Hitachi America, Ltd., Industrial Components & Equipment Division, today announced the new WJ200 series of inverters. This new model advances the benchmark for performance and functionality in micro-size AC drives. The WJ200 is a sensorless vector (SLV) drive capable of 200% or greater torque across the speed range.  Speed regulation at low speed is dramatically improved – fluctuation is half that of previous models. Improved trip avoidance measures have been incorporated for unsurpassed system reliability and availability.

The WJ200 offers PLC-like functionality by means of the integrated Easy Sequence (EzSQ) programming function. Programs up to 1024 lines can be created on a PC using this structured language tool, and can then be transferred to the WJ200. In this way, very sophisticated control schemes can be created without the use of external controllers.

Simple position control applications are also possible with the WJ200 utilizing the integrated pulse input. Together with EzSQ, intricate motion profiles can be developed. Further adding to its flexibility, the WJ200 has the capability to drive both induction motors and permanent magnet (PM) motors – a single drive for two motor realms.

A new EzCOM peer-to-peer communications function is standard and allows multiple WJ200s to share data. One drive is designated as the “administrator,” and controls the network. Other drives on the network can be master or slave, with masters able to write data to any designated slave(s). Master/slave roles are rotated under the control of the administrator automatically. Up to 8 masters can reside on the network, and up to 32 drives (up to 247 drives, if external signal repeaters are used). The administrator can be master or slave also. EzCOM allows for creation of sophisticated coordinated systems without any additional external hardware or programming.

Other desirable standard features include a safe-stop function (meets ISO/IEC standards), password protection of parameters, real-time clock, standard Modbus/RTU RS-485 serial port, micro surge voltage suppression, dynamic braking circuit, and much, much more. The WJ200 is designed for long service with bus capacitors and cooling fans designed for 10 year life and varnish coating of circuit boards. The WJ200 also is RoHS compliant. Option boards will be released in the near future to allow communication via DeviceNet, CompoNet, ProfiBus, CANopen, and others.


http://www.clrwtr.com/Hitachi-SJ700.htm

Hitachi America, Ltd., Industrial Systems Division, today announced the introduction of the SJ700 Series of inverters. The SJ700 significantly expands on the performance, capabilities and functions of its predecessor, the SJ300.

Hitachi reasserts its technological leadership with an improved sensor-less vector (SLV) control algorithm that enables the SJ700 to develop more than 200% starting torque at 0.3 Hz. The SJ700 can develop 150% torque at 0 Hz, ideal for vertical lift applications, using Hitachi’s unique “0 Hz Domain” open-loop control mode. Hitachi has also greatly simplified the auto-tuning process, making commissioning trouble-free.

A noteworthy enhancement in the SJ700 is Hitachi’s EzSQ (Easy Sequence) built in programming function. It’s like having a PLC built into the inverter! In many cases, the need for a separate PLC can be eliminated. The program is developed on a PC and then downloaded to the inverter using the simple to use EzSQ software provided at no charge.

The SJ700 also incorporates true servo-like position control, offering a low-cost motion control solution. Mated with a general-purpose induction motor with an encoder, the SJ700 is given a position command, speed command, and acceleration/deceleration times. The shaft will move from position A to position B following the defined profile and then maintain the shaft in servo lock status.

Hitachi has also packed many new features into the SJ700. Features such as, but not limited to include, patented micro-surge voltage suppression (to protect the motor winding insulation), advance trip avoidance functions, configurable sink/source logic on I/O, built-in dynamic braking circuit in models up to 30 hp (22 kW) and built-in EMC filter up to 75 hp (55 kW), have been added.

The SJ700 also includes anticipated features, such as built-in RS485 Modbus/RTU communication, and options for other communications networks, such as Ethernet Modbus/TCP, DeviceNet, Profibus and LonWorks. The SJ700 can be configured via the front-mounted keypad or using Hitachi’s ProDrive PC-based software.

The SJ700 carries CE, UL, cUL and c-Tick marks, and is RoHS compliant, exemplifying a true global product. The SJ700 series will be released in stages, with the 250 hp to 500 hp ratings currently available. Other power ranges from 200 hp and down will be released later this year.


http://www.clrwtr.com/PDF/Hitachi/Hitachi-Regenerative-Converter-Unit.pdf

Hitachi America, Ltd. today announced the release of its RCU Series of regenerative converter units. The RCU Series offers an affordable “green” alternative to traditional dynamic braking (DB) systems. Instead of wasting regenerative energy as heat, the RCU reclaims that energy, converting it into 3-phase alternating current (AC) power. The energy is recycled through the AC line, resulting in increased energy efficiency and reduced energy consumption. In many applications, the amount of energy that can be reclaimed is quite significant, thus providing a measurable return on investment and short pay-back cycle relative to the cost of the RCU.

Furthermore, the waste heat generated by conventional DB often creates the need for additional cooling and air-conditioning, which can be costly. Thus, the elimination of DB waste heat is a secondary benefit of the RCU Series. In this way, incorporating an RCU in the system allows for a smaller cooling system (HVAC), offsetting the up-front cost of the regenerative unit, and additionally, reducing the demands placed on the cooling system.

The RCU is simple to install and operate, with only five connections necessary for basic operation. It incorporates LC-filtering to mitigate harmonics and an LED display for monitoring of operation and faults. The RCU is available in several sizes, and units can be parallel-connected for higher power handling.



Hitachi America, Ltd., today announced the release of a new series of NEMA3R and NEMA12 rated panels. Three tiers of standardized panel design are offered with an assortment of available options. Now, Hitachi can deliver a pre-engineered panel design for almost any application that is available for quick delivery. Models are available from 7.5 hp to 75 hp at 230 VAC, and 7.5 to 150 hp at 460 VAC. Additionally, larger capacity versions are available on a custom basis. Each standard panel includes a Hitachi L300P Series inverter ideally suited for pump, fan or other applications in demanding indoor or outdoor environments. The "Base" model features AC input line reactors; thermostat controlled cooling fans with filters; and convenient terminal for user connection to power, motor and control circuits.

“Standard” models add input power disconnects and fusing, and a second inner door with an inverter digital operator and associated indication lights. A "Standard with Bypass" model adds two-contactor bypass functionalities with a drive/bypass mode selector switch.

Add-on options include surge suppression, output motor reactor, manual disconnect, local-off-remote switch, internal space heaters, and others. The panels are also offered for leg or pole mount.



Hitachi America, Ltd., Industrial Systems Division, today announced the availability of the IPU-PSM option board. When installed in a Hitachi L300P Series inverter, the IPU-PSM adds Pump Sleep Mode functionality to the standard built-in PID function.

Standard PID control may, depending on system demand, allow a pump to operate at undesirably low speeds for prolonged periods of time. This can cause mechanical issues with certain pump types, and in general is a wasteful use of energy, since most pumps do not generate significant flow or head at low speeds.

The IPU-PSM allows for the specification of a lower limit on inverter output frequency. Should the PID function call for a frequency below that limit for a user defined period of time, the inverter will go to “sleep”, meaning the inverter output will shut off and the pump stops. The IPU-PSM continues to monitor the system pressure feedback via the inverter’s PID Deviation parameter. If system pressure drops below a defined level for a specified period of time, the inverter will “wake” and resume normal PID pressure regulation. In addition to this automatic operation, two digital inputs are available on the IPU-PSM: to force the inverter to wake, and to disable the sleep function.

The IPU-PSM is easily configured by means of four inverter parameter settings, and no additional hardware is required.



Hitachi America, Ltd., Industrial Systems Division, today announced the introduction of the high-capacity SJ700 Series of inverters. The SJ700 extends Hitachi’s model range up to 500 hp, and significantly expands on the performance, capabilities and functions of the SJ300. Three models, 250 hp, 400 hp and 500 hp are being released at this time. The SJ300 remains to cover the range from 200 hp and below.

Hitachi reasserts its technological leadership with an improved Sensorless Vector (SLV) control algorithm that enables the SJ700 to develop more than 150% starting torque at 0.3 Hz. Using Hitachi’s unique “0 Hz Domain” open-loop control mode, the SJ700 can develop 130% torque at 0 Hz, ideal for vertical lift applications. At the same time, Hitachi has greatly simplified the autotuning process, making commissioning trouble-free.

Another noteworthy enhancement in the SJ700 is Hitachi’s Easy Sequence ( EzSQ) built in programming function. It’s like having a Industrial Control System (PLC) built into the inverter. In many cases, the need for a separate PLC can be eliminated. The program is developed on a PC, and then downloaded to the inverter using the simple-to-use EzSQ software provided at no charge.

As if those improvements were not enough, Hitachi has packed other new features into the SJ700, such as patented Micro Surge Voltage suppression (to protect the motor winding insulation), advance trip avoidance functions, configurable sink/source logic on I/O, and much more.

The SJ700 also has features you’ve come to expect, such as built-in RS485 Modbus/RTU communication, and options for other communications networks, such as Ethernet Modbus/TCP, DeviceNet, Profibus and LonWorks. The SJ700 can be configured via the front-mounted keypad or using Hitachi’s ProDrive PC-based software.

A global product, the SJ700 carries CE, UL and c-Tick marks, and is RoHS compliant.

Littelfuse, Inc., the global leader in circuit protection, today announced its LSP05/LSP10 Series Surge Protection Device Modules were named a winner in the EE Times and EDN 2015 UBM Canon ACE Awards in the “Ultimate Products: LEDs and Lighting” category. The awards program honors the people and companies behind the technologies and products that are changing the world of electronics.

The winners were announced at an awards ceremony on Tuesday, July 21, at the Santa Clara Convention Center, during the Embedded Systems Conference Silicon Valley. Bharat Shenoy, the director of technical marketing at Littelfuse, was on hand to receive the award. He noted, “I know everyone at Littelfuse, especially those on the product development and marketing teams, feels very honored today by this award. The LSP05 and LSP10 Series products represent the collective efforts of many people striving to offer our customers the most advanced and cost-effective circuit protection solutions available.”

Constructed with Littelfuse thermally protected varistors, the LSP05 and LSP10 Surge Protection Device (SPD) Modules provide robust surge current handling capability. These optimized surge immunity solutions protect outdoor LED fixture investments with maximum lightning surge current ratings of 20,000A (LSP10) and 10,000A (LSP05). Their compact form factor (48x48x30mm) makes them easy to mount inside a luminaire; mounting tabs simplify installation and replacement. A built-in thermal disconnect function provides additional protection from catastrophic failures and fire hazards, even under the extreme circumstances of varistor end of life or sustained overvoltage conditions.

Metal Oxide Varistors (MOVs) used to protect LED luminaires degrade gradually after a large surge or multiple small surges. This leads to increasing MOV leakage current, raising MOV temperature under normal conditions. A thermal disconnect like that used in the LSP05 and LSP10 senses this temperature increase as the MOV approaches its end-of-life condition, at which point it will open, removing the MOV from the circuit and preventing its catastrophic failure.

“We are continually amazed at the level of creativity in the design, innovation and technology exemplified by these award winners,” said Suzanne Deffree, Executive Editor at UBM Canon's EDN. “The ACE Awards celebrate the highest achievements in innovation and creativity in electronics design, and selecting one organization or individual that stands out above the rest is incredibly challenging. We are pleased to be able to celebrate their achievements.”

Littelfuse, Inc., the global leader in circuit protection, has introduced the XGD Series XTREME-GUARD™ ESD Suppressor, available in 0402- and 0603-sized, flat-topped surface mount packages. Based on breakthrough ESD technology, it protects sensitive electronics against electrostatic discharges as high as 30kV and is suitable for high voltage applications up to 32VDC. When correctly integrated into a circuit design, the XGD Series can safely absorb repetitive ESD strikes nearly four times the maximum level specified in the IEC61000-4-2 international standard without performance degradation. Extremely low capacitance makes the XGD Series suitable for use in high-frequency and high-speed data, video, antenna and I/O circuits. Even after multiple ESD strikes, it exhibits ultra-low current leakage (<1nA), ensuring minimal power losses, so it’s well-suited for protecting battery-powered electronics like wearables. Both sizes offer much higher voltage ratings than other ESD suppressors with similar board footprints; they also offer far greater ESD protection than many TVS Diodes while providing much lower capacitance and leakage current and higher voltage ratings.

Applications can be found in the industrial, consumer electronics, telecom/datacom, and white goods/home appliances markets.

“XGD Series XTREME-GUARD™ ESD Suppressors are designed for high-frequency, high-speed applications that demand high voltage ratings and extreme ESD protection,” said Johnny Chang, global product manager for the XGD Series line. “At the same time, they are ideal for general-purpose ESD protection in wearable technology, smart TVs, smartphones, tablets, set-top boxes, gaming consoles, stationary and portable medical devices, etc.”

Littelfuse, Inc., the global leader in circuit protection, has introduced two new product series, the SP4044 and SP4045 Series TVS Diode Arrays (SPA® Diodes), designed to protect sensitive electronics from destructive electrostatic discharges (ESD) and lightning-induced surge events. Low capacitance diodes are integrated with an additional zener diode to protect each I/O pin against ESD and high surge events. These robust devices offer a benchmark-setting surge protection/capacitance ratio; safely absorbing up to 24A of lightning-induced surges while presenting only 1.5pF per I/O-to-Ground connection. This helps to assure minimal signal degradation. The array can also handle a minimum of ±30kV ESD, so electronics manufacturers can realize greater protection and enhance product reliability in the field. The low loading capacitance also makes the SP4044 and SP4045 Series ideal for protecting high speed signal pins. “Straight-through” routing allows these components to sit on top of the lines they protect, eliminating stub parasitic capacitance and inductance and ensuring higher signal integrity.

Typical applications for the SP4044 and SP4045 Series TVS Diode Arrays include protecting HDBaseT, 2.5 and 5 Gigabit Ethernet, and 10/100/1000 Ethernet ports, as well as secondary protection for T1/E1, T3/E3, and high-end audio-visual equipment lines.

“These low capacitance, low clamping protection devices will make the design engineer’s life just a little bit easier,” said Tim Micun, product manager for the TVS Diode Array (SPA® Diodes) line. “By allowing straight-through routing, they eliminate complicated trace capacitance calculations and data reflections, and support high signal integrity on the ultra-fast HDBaseT, 2.5 and 5 Gigabit Ethernet ports.”

Vactor Manufacturing, the industry leader in vacuum excavators, sewer and catch basin cleaners and industrial vacuum loaders featuring innovative technology and custom configurable designs, today introduced the HXXpose™ nozzle for increased productivity and operator safety in typical hydro excavation applications. The nozzle works with Vactor’s line of vacuum excavators, as well as all other makes and models of vacuum excavation trucks. The rotating water jet agitates a larger area of soil with the same amount of water as a straight jet nozzle for higher efficiency, blasting a 0-degree stream of water rated for pressures up to 3,200 psi, while rotating at a high speed to provide an 18-degree cone of coverage.

“At Vactor Manufacturing, we are committed to continuous improvements of our products so we can deliver the best possible performance solutions to our customers,” said Ben Schmitt, product manager at Vactor Manufacturing. “The heavy-duty HXXpose nozzle, which is standard on all Vactor vacuum excavators, addresses our customers’ growing demand for increased productivity for their hydro excavation projects. This smaller nozzle provides the same productivity as similar, higher water-flow nozzles, while using less water. This allows the operator to remain on the job longer and complete the project with less mess and less downtime to refill the water tank.”

The rugged HXXpose nozzle features high-wear resistant, tungsten carbide internals and a ½-inch, corrosion-resistant FNPT stainless steel casing to hold up against the harshest environments and conditions. The nozzle’s urethane outer coating protects the operator and underground utilities on the site from electrical conduction. The HXXpose nozzle also features a minimum inlet pressure of 1,000 PSI (69 bar) and a maximum water temperature of 180 degrees F (82 degrees C). For extended life and lower operating costs, rebuild kits are available.

Power management company Eaton today introduced its new Bussmann series 1000 volts direct current (Vdc) NH size photovoltaic (PV) solar fuses specifically designed for protecting and isolating array combiners, re-combiners, disconnects and inverters. With the industry’s highest current density and two available mounting options, the NH PV fuses provide design flexibility in a compact size.

Eaton’s NH PV fuses meet global agency standards, simplifying designs for worldwide markets, and are available in traditional blade and bolt-on versions. The traditional blade version can be used with a fuse block to provide quick, tool-less replacement for easy maintenance. The bolt-on version can be bolted directly to a bus bar, reducing components and assembly time. With a common bolt pattern, the NH PV fuses are designed to easily integrate into a standardized bus bar design, regardless of fuse ampacity.

“Eaton delivers a range of overcurrent protection devices for solar applications that protect valuable balance of system equipment and support uptime,” said Kevin Calzada, product manager, solar fuses, Eaton’s Bussmann Division. “Our latest NH fuses for PV applications maintain Eaton’s industry-leading efficiency and low-operating temperatures.”
Both fuse versions come with system monitoring accessories that provide dual visual indication and optional microswitches (for traditional blade version only) to make it easier to monitor system processes.

Power management company Eaton today announced a game-changing fused disconnect switch designed to help data centers achieve critical reliability and support advanced power distribution architecture. The new Bussmann® series Low Profile Compact Circuit Protector (CCPLP) is the industry’s most compact Underwriters Laboratories (UL®) 98 Listed fused disconnect switch.

“Eaton’s fusible circuit protection solutions are engineered to support higher energy efficiency and greater power density data center designs, while helping meet code compliance with respect to interrupting rating and safe work practices,” said Nick Stone, Eaton’s Bussmann Division. “The new CCPLP provides expansive features in the industry’s smallest fusible switch footprint to benefit designers, maintainers and owners of modern mission-critical environments by enhancing efficiency, reliability and safety.”

Designed to streamline panel installation and simplify selective coordination requirements in mission-critical environments, the new Bussmann series CCPLP accepts branch circuit rated fuses that are current limiting and up to a 200 kiloampere (kA) interrupting rating. All configurations are designed for use in global applications and offer alternating current voltage ratings up to 600 volts.

To support application flexibility, mounting and panel layout dimensions match common low-profile circuit breakers, providing an easy, alternative fused circuit protection solution. Additionally, all versions are disconnect rated to provide means for load isolation while Class CC, 20 ampere (A) Class G, and IEC 10x38 versions are suitable for both branch circuit disconnect and branch circuit protection.

To enhance safety, the fused disconnect switches are IP20 rated and meet International Electrotechnical Commission (IEC) finger-safe requirements for panel mount installations. Further, a built-in switch handle interlocks the fuse access to help prevent removing the fuse under load, and the use of a pin-out device provides a lockout/tagout means for enhanced safety.

Power management company Eaton today announced the C308F Bussmann Series of fast-acting, ceramic tube fuses for intrinsic safety requirements used in hazardous environments such as network barriers and other equipment used in mines, oil drilling structures, gas stations, gas meters, chemical refineries and hazardous material transportation.

“Manufacturers of intrinsically safe barrier networks need fast-acting devices that prevent explosions in extremely hazardous conditions,” said Vincent Wang, global product manager for Eaton’s Electronics Division. “This fuse line offers advanced overcurrent protection that meets internationally-defined safety requirements where electrical equipment is required in the presence of highly volatile materials.”

Intrinsic Safety (IS) is universally recognized under the specification EN60079-11, which is a low-energy signaling technique that prevents explosions from occurring during industrial activity by ensuring that the energy transferred to a hazardous area is well below the energy required to initiate an explosion.

The ceramic tube construction of these fuses meets EN60079-11 standards for explosive environments and delivers a high interrupting rating for circuit protection up to 250 volts (V) and 250 milliAmperes (mA) for both alternating current (AC) and direct current (DC) power.

These fast-acting C308F fuses provide a high breaking capacity of 4,000 amperes (A) in a compact 3 x 8.4-millimeter size.

The C308F Bussmann series fuses can be used in intrinsically safe devices defined according to the international standard by the International Society for Automation (ANSI/ISA-RP12.6: less than1.5V, less than 0.1A, and less than 25 milliWatt during operation) such as contactors, thermocouples, LEDs, non-inductive potentiometers and resistors. They can also be used for non-simple devices such as transmitters, transducers, solenoid valves, and relays.

Through the integration of the communication interface IO-Link for the sensor principles diffuse mode sensor with background suppression and SmartReflect (the light barrier without a reflector), the optical O300 and O500 NextGen sensors have improved their already outstanding efficiency. The IO-Link interface facilitates the rapid startup of systems through the automated transmission of various parameters such as sensing distance accurate to the millimeter, light or dark operate, or switching points. In addition, the new Baumer filter functions guarantee the safe and reliable detection of difficult objects, for example objects with holes.  Through the option of automatically changing the locking times of the sensors, these sensors also have a high level of user-specific functional reliability.

Thanks to two powerful filter functions, the new O300 and O500 sensors with IO-Link are also suitable for difficult detection tasks. The first filter function delays the response and/or the release time of the sensor. For example, this function makes it possible to reliably detect objects with small holes or also objects on conveyor belts with holes. The second filter function makes it possible to set a minimum pulse length, thus facilitating the detection of small, narrow, fast objects. Here, the sensor lengthens very short switching signals until the minimum pulse length is reached for the controller in question, which can then further process the switching signals reliably.

A further special feature of Baumer is the increased functional reliability of the sensors. Thanks to the innovative qTeach procedure, optical NextGen sensors have a standard locking time. This protects the sensors from unintentional manual manipulation. With the Baumer IO-Link profile, this locking time can be individually set or changed, depending on everyday production requirements.

IO-Link also offers the option of efficiently using the diagnostics features integrated in the optical NextGen sensors. Information about soiling or signal quality can be retrieved directly and used to optimize system availability (e.g. through preventive maintenance) and productivity.

The Baumer company presents a new version of the OptoPulse® EIL580 incremental encoder family, which offers protection from induced shaft currents.

The new version with hybrid bearings also improves reliability, since in comparison to all-steel bearings these have a current-insulating effect and thus completely eliminate bearing damage caused by shaft currents.

OptoPulse® EIL580 encoders are characterized by robust design and extreme durability. The ShaftLock bearing design was invented by Baumer, and guarantees reliable functioning even under the most adverse conditions. The metal shoulder between the two ball bearings reliably protects the internal sensor technology from axial impacts and stresses. The high-quality materials and the precision-machined mechanical system guarantee optimum radial and axial running over the entire service life.

The modular system of the OptoPulse® EIL580 series forms the basis of a wide variety of product versions, which are compatible with all current electrical and mechanical standards. The product design unites form and function, making installation easier. With their clean lines, the encoders integrate themselves unobtrusively into the application.

With a repeat accuracy of 1µm, about 1/5 of a normal hair, the My-Com precision switch from Baumer has been mastering precision tasks such as quickly and reliably setting reference points and monitoring tolerances for a good 50 years. Despite its grand old age, My-Com is still one of the most precise and compact mechanical limit switches in its class worldwide. Even measuring equipment and machine tools of every kind can be verified or referenced by a micrometer.

The name My-Com is based on the term Micro Commutator. This precision switch was the first proof of the high performance levels that Baumer Electric was and still is able to achieve. My-Com's success story started back in 1966. The smallest and most precise limit switch in the world was launched by consistently applying the latest technologies, procedures and materials at that time. Thanks to its unique design, it can meet the highest requirements for precision and robustness with only three moving parts, and high-quality individual components such as bright gold-plated contacts.  Another reason for its precise repeat accuracy is based on the mechanical refinement of a highly accurate and industrialized ceramic tappet, which can move the gold-plated ball inside the housing with a force effect from 30 cN, thereby interrupting the high-quality switch contacts. My-Com therefore retains its high precision and repeat accuracy over up to 10 million switch cycles.

Users receive the standard My-Com version with the same level of consistent simplicity and precision as before, with the usual "normally closed function". Through integrated electronics, "normally open" versions are also possible for directly controlling SPS and other electronic inputs as well as LED output indicators. For use in harsh environments with soiling, drilling water or even abrasive dust there is the My-Com version with protection class IP 67, thanks to a sealing membrane made of Viton, an extremely resistant sealing material. The modular structure of the switch's inner workings enables a high degree of flexibility. Various single parts can be freely combined and enable a number of variants and tailor-made customer solutions. This is precisely what makes the precision switch from Baumer unique and universal.

Since it was patented, the My-Com has been used in thousands of different application possibilities. So it's not surprising that even space research has become aware of Baumer's My-Com. Since 2005, My-Com has been ensuring precise mirror adjustment for micrometers in various models of ESA's weather satellites, and is also used on the international space station ISS and other space probes. Other industries such as graphics, machine tools, textile machines, packaging and handling, robotics and pharmaceuticals, etc. are also impressed by the My-Com precision switch's range of services and reliability. Wherever accuracy and precision are crucial for the end product, My-Com from Baumer finds its place and works reliably.

Since their inception more than 100 years ago, the two main types of motors in use have been open drip proof (ODP) and totally enclosed fan-cooled (TEFC). When a motor is operated in a dry environment with little or no exposure to water or contaminants, the ODP motor is a viable choice. TEFC is typically the motor choice for equipment exposed to moisture or the environment.

As industry demands increased and sealing technologies improved during the latter part of the past century, manufacturers were able to do more to protect motors from the environment. With the growth of the food industry, guidelines were created to ensure that the equipment used to produce food was clean and sanitary. The washdown motor was the result.

Early washdown motors include painted white motors, which provide a clean appearance and improved sealing (compared with general purpose motors), and paint-free motors, which provide a combination of aluminum and stainless parts with no painted surfaces. The more costly cousin to these first two lines of motors is the stainless steel motor.

Although the varieties of washdown motors have increased over the years, many end users still buy motors based on the price tag, looking for the most cost-effective design that will provide the best longevity. Because of this paradigm, some users may not be willing to pay 40 to 50 percent more for a stainless steel motor. In the past several years, however, motor users have embraced the idea of total cost of ownership, which goes beyond the initial purchase price.

Washdown motors are generally categorized in three categories, listed here in order of price and feature set: painted white washdown, paint-free aluminum and stainless steel. Many end users, particularly those in large food processing facilities, may utilize all three. Painted washdown motors still offer users a good value in that they can use them in a variety of wet or dry applications that see some levels of moisture and some light washdown. Others may upgrade an area of the plant to a paint-free motor, which utilizes a combination of stainless steel and processed aluminum components (no paint). These motors also have better shaft seals and can withstand higher water pressures and some cleaning solutions.

In the most harsh applications, however, the stainless steel motor is the motor of choice, as it uses a number of the best technologies available, such as fully welded conduit boxes, O-rings in endplate to stator joints and enhanced sealing around the shaft exit points. Understanding these feature levels will greatly improve the end user's ability to apply the proper motor to the proper application.

When evaluating total cost of ownership, value is a vital factor. While white washdown motors are still widely accepted and used more than stainless motors, the food industry is beginning to recognize the value of spending the extra money on a premium efficient stainless product.

Stainless steel motors continue to gain acceptance, and much of the need for them in the U.S. is driven by the passage of the Food Safety Modernization Act. This act covers facilities registered with the Food and Drug Administration (FDA) under the Bioterrorism Act of 2002. This law gives the FDA the authority to shut down a food processor or other related facility that indicates by reasonable belief that a hazard exists. A shutdown for an indefinite period of time can have far-reaching implications for a food processor. The purpose of the law is to ensure beyond any reasonable doubt that all equipment in a facility does not pose any risk or even an appearance of risk that would cause a negative FDA inspection. Stainless steel motors can help provide this assurance.

One point of contention with washdown motors, especially foot-mounted designs, has been the perception that food can collect in crevices. Most motor designs contain models that have crevices around the motor feet that can collect food, which can lead to contamination. When selecting a stainless motor, users should consider equipment that has smooth corners and minimal crevices or areas that can collect contamination. Better use of seals around the motor shaft, such as dual seals or labyrinth seals, as well as O-rings used in place of traditional caulk-style materials have also improved washdown motors over the past several years.

While these designs are more costly up front, stainless steel premium efficient motors are key to improved total cost of ownership and a more sanitary environment.

An innovative generator cooling system from ABB enables increased turbine genset performance and economy in demanding applications where cooling water is not available. The space-saving solution helps OEMs to offer higher power levels from standard turbine skids.
ABB, the leading power and automation technology group, is introducing an independent, closed water cooling system for generators in turbine gensets. The new CAWA* cooler meets clear demands for a compact and cost-saving solution on oil and gas platforms.

Water cooling (CACW) offers the best generator efficiency, but it can only be used if there is a separate cold water supply on-site. The new CAWA cooler is designed for demanding applications such as oil and gas platforms, where cooling water is not available or space limitations are a key issue. It integrates an additional water-to-air cooler on top of the generator’s air-to-water heat exchanger, providing an independent closed circuit water cooling system.

This smart space-saving concept offers over 60% weight reduction by replacing the large, less efficient and more expensive air-to-air cooler (CACA) and can be delivered with shorter lead times. At the same time, the CAWA-cooled system will enable higher power levels from standard sized gensets which already fit OEM’s standard turbine skids. The CAWA’s compact frame can also handle the strong winds encountered by offshore platforms, while larger air to air coolers require more rigid support.

The CAWA cooler consists of three sub-systems: the Machine Cooler which cools down the internal air in the generator, the Air Blast Cooler, which has six fans to cool down the water coming from the generator’s Machine Cooler, and the Piping System that circulates the cooling medium (ethylene glycol / water mixture) between the two cooler units.

The cooler comes in two versions, standard for safe areas and premium for ATEX certified Zone 2, ExnA requirements for potentially explosive atmospheres. The separately delivered cooler weighs a maximum of 4,500 kg in total - considerably less than a comparable air-to-air cooler, which typically weighs 7,500 kg and it requires no additional piping. ABB has patent protection pending for the CAWA cooler concept.

Though it's long been rumored that step motors are driven by tiny hamsters on wheels contained inside, I can assure you that this is not only untrue, but also promulgated by unscrupulous pneumatic actuator salesmen.

So, how does a step motor work? In reality, step motors operate by electromagnetism. Specifically, a permanent magnet rotor such as the one shown below is attracted to electromagnets that reside in the stator.

Observe that the rotor teeth on the front of the rotor are offset from those on the back. Between the two rotor halves is a strong permanent magnet that ensures all the teeth on the front of the rotor are magnetic north while those on the back are south poles. Remember this; you'll be tested later. When electromagnetic stator coils are connected to a suitable step motor driver, the motor's position, velocity and acceleration can be precisely controlled without any need for feedback. Such simplicity is the reason step motors are a hallmark of the automation industry.

Those “in the know” think ServoSETS packaged servo systems are the way to go! At the beginning of June we announced that 100 and 200 Watt ServoSETS packaged servo systems are available for immediate shipment from stock. On June 18 they went live on our website. Look for the banner ad on our home page and the new link under the Products menu.

ServoSETS packaged servo systems have already started shipping. The proud owner of the first system shipped is a researcher from one of the most prestigious universities in the U.S. doing a study on state-of-the-art manufacturing solutions. He chose a ServoSET packaged servo system because it was quick and easy to order, competitively priced, and exactly what he needed for his research project. He was up and running immediately, and then used this application note to refine the drive configuration for his final requirements.

Applied Motion is pleased to announce the addition of 0.9 degree step motors to our product offering. 0.9 degree step motors are advantageous when a microstepping drive is not available. Because 0.9 degree motors have twice the step resolution (400 steps/rev) than 1.8 degree step motors (200 steps/rev), they run inherently smoother when driven with full or half step drives.

Microstepping drives, like Applied Motion’s ST, STR and STAC drives, nullify the smoothness benefit of 0.9 degree step motors because these drives are capable of creating equal smoothness with 1.8 degree motors. However in some applications microstepping is not available, such as when a very basic full or half step drive is used, and for these applications a good way to gain smoothness is to use a 0.9 degree motor.

These new motors offer the same great performance and price as our other step motors. They come in NEMA frame sizes 14, 17 and 23. Please visit the 0.9 degree motor page to learn more.

Advantech (TWSE: 2395.TW) today introduced HVC-6300, an HEVC capable Full HD video streaming solution in a small lightweight form-factor. HVC-6300 connects directly to a video source via SDI or HDMI, and allows live video to be encoded, stored, and transmitted via 3G/4G/LTE/Wi-Fi to an OB van, a broadcast station or uploaded to a server-based cloud environment. Applications for HVC-6300 include live streaming for sports events and electronic news gathering, tele-medicine, and remote video surveillance.

HVC-6300 supports the High Efficiency Video Codec (HEVC) at up to FullHD 1080p resolutions. HEVC support offers a substantial benefit over existing solutions by reducing the bit rate by approximately 50% when compared to an equivalentquality video stream encoded using AVC / H.264. This reduces the network bandwidth required, or enables either more channels or a higher resolution video delivery over the same infrastructure. It is particularly relevant for mobile video transmission which often has a limited bandwidth.

Advantech, a leading embedded computing solution provider, today announced the release of its new thermal solution for COM Express Basic Module — the Dynamic Heat Conduction System (DHCS).

This is an advanced technology which differs from traditional COM Express thermal solutions; DHCS uses a built-in dynamic block to resolve the dimension tolerance between CPU and thermal module, so the block can contact the CPU surface directly and tightly without any gap pad. This revolutionary design shortens the heat conduction path, and makes heat dissipation more efficient. In a direct comparison test with a traditional two-piece thermal module, the thermal solution with DHCS delivered a CPU temperature 20 ˚C lower. This can benefit applications that require high computing performance, and is especially suitable for high-end COM Express solutions and harsh application conditions, such as those in the traffic, medical, and military sectors.

DHCS is different from the traditional thermal module, which usually uses a gap pad as thermal interface material to fill any mechanical gap. In the DHCS solution, we have replaced the gap pad with a self-adjusting copper block that directly contacts the CPU. Moderate pressure keeps the dynamic block in tight contact with the CPU surface for excellent heat transfer. This pulls heat away from theCPU quickly and helps the CPU achieve ultimate computing performance.

In order to improve heat dissipation, we reduced theheat conduction path; now the CPU contacts the copper block directly without any intervening material. Since the DHCS is a compressible and resilient unit, moderate pressure is sufficient to mate the block with the CPU. This reduction in pressure on the CPU die takes a load off the underlying PCB. Reduced loading means the board stays flat.

The DHCS thermal solution uses standard screws for assembly, so users need only follow the torque specification of the screw type to assemble the thermal module to the carrier board. This makes assembly easy, and screw heads can be firmly locked to the thermal module to avoid loosening if the system is to be operated in a vibrating environment.

Machine components and installations in the F&B industry have to be easy to clean. As a result, Murrelektronik's new MVP12 Steel distribution box is made of high-quality stainless steel. It is an ideal solution to implement a decentralized approach in F&B machines and installations.

The F&B industry doesn't make any compromises where cleanliness and corrosion protection are concerned. Dirt must be easy to remove. Parts are exposed to high pressure wash downs with aggressive cleaning agents.

This makes stainless steel the preferred material. Murrelektronik's MVP12 Steel distribution boxes feature a closed stainless steel housing and threaded sleeves made of V4A stainless steel ensuring an IP69K rating. No matter if you are cleaning, rinsing or disinfecting MVP12 Steel will always operate reliably.

Prior to the introduction of MVP Steel, individual cables had to be routed through a system - a very complex task in the F&B industry because of the cleanliness requirements. Now a single homerun cable replaces the individual ones. This reduces material costs, the amount of wiring and space required. Moreover, terminal boxes are no longer required in the field. MVP12 Metal is installed close to the process so sensors and actuators can be connected to one of its eight ports with the shortest possible cables.

To complement the MVP12 Steel distributors, Murrelektronik offers M12 Steel connectors that are fully potted and made of corrosion resistant stainless steel. Together the distribution box and cordset form a closed and rugged unit for F&B applications.

Murrelektronik's new power connectors (M12, M15 and M23) make motors easy to connect. The M12 power connector is the most compact and powerful 5 pole M12 connector on the market. The new M15 power standard connection technology of the MQ15-X-Power connector enables extremely quick assembly. Murrelektronik's M23 connectors are an established standard solution to connect servo motors.

Perfect contacts, seal and media resistance are basic requirements to all connector types. The field of motor connections requires additional, special features. Wide connection cross sections, high performance in a very compact design and most important: an integrated anti-vibration locking mechanism that makes sure the connector is tight even with very strong vibrations. Murrelektronik offers power cables for different applications and motor types that meet these requirements.

Its very compact design makes the M12 Power connector ideal for linear drives, brushless DC or step motors.  It has a capacity of up to 2 x 16 A at max. 63 V AC/DC. The Murrelektronik product range is comprised of cord sets with open ended wires, connection cables, flange connectors and adapters - which offers a vast number of installation options.

The MQ15 X is designed for quick connections with reverse polarity protection of asynchronous motors up to 7.5 kW. The connector offers three power contacts up to 16A, PE and two auxiliary contacts up to 10A. The quick connection technology ensures sealed connections in no time. The molded plugs make sure the connector is sealed, tamper-proof and prevents wiring errors. The program range is complemented by flange connectors with an M20 outer thread. These connectors are simply attached to terminal boxes with a screw connection.

With the M23-Drives range, Murrelektronik offers the most powerful 8 pole M23 connector on the market (with a reference ambient temperature of 40° C). With 28 A/ 630V per pin for the power contacts and 8 A/300V for the signal contacts, the connectors are suitable even for high performance drives and servo motors of the AC/DC range.  A complete 360° shielding ensures very low interference emission. The M23 also features a high-quality locking mechanism that ensures permanently sealed connections with the hex thread and the suitable torque wrench. The coding arrow on the housing is a practical installation aid. A corrugated tube connection, high-quality, original Siemens cables and excellent seal even when exposed to oil in industrial applications are additional strong points of Murrelektronik's M23-Drives cordsets.

Murrelektronik's MICO protective modules for UL508A control cabinets are a proven solution for intelligent power distribution and efficient branch circuit’s protection. 8 different MICO modules are now NEC Class 2 approved, so you can efficiently design your power distribution scheme.

Class 2 Circuits are circuits with limited energy and a maximum power of 100 VA. According to the NEC & UL definition, class 2 circuits limit the risk of electrical fires and electric shocks due to their limited energy. Therefore, according to UL508A standard (for control cabinets), any component used and attached devices on the branch circuit in a Class 2 circuit don’t require investigation.

So far, an individual NEC Class 2 approved power supply was used to create a class 2 circuit and it required a lot of space. This method wasn't cost effective and caused a lot of wiring and planning effort.

With Murrelektronik's MICO NEC Class 2 approved module, it is now possible to design NEC Class 2 circuits even faster, in a more compact and cost effective way. All you need is a standard power supply unit (that doesn't necessarily has to be NEC Class 2 approved) combined with MICO to design two, four or eight separate load circuits with limited energy in a simple way. By connecting several MICO modules with the integrated bridging system, the number of channels can be increased up to a total current of 40 A. Components attached to the MICO’s marked NEC Class 2 outputs devices no longer need UL-approval.

Murrplastik Systems, leaders in cable drag chain products and innovation, have introduced a new model into their PowerLine Cable Drag Series designed to meet the growing demand for greater loading, distance and speed capacities. The new MP 52.6 features a significant increase in chain side link wall thickness resulting in a 1.5X increase in maximum tractive force.

In addition to the optimized distribution of tensile forces, the MP 52.6 cable drag chain also features more stable operation and less wear while considerably extending the chain’s useful life. Additionally, a new latch mechanism answers the demand for even greater simplification of installation and servicing work. This new latch system makes it possible to open the frame bridges from the top allowing the cable drag chain to be left where it is in the guide channel during upgrades and repairs.

Another new optional feature of the MP 52.6 are sliding blocks that serve to further minimize wear to the chain side links. They feature a specially designed 4 mm wear zone and are fitted onto the side links in the cable drag chain’s inside bend instead of the usual frame bridge interlocks. This results in the sliding blocks wearing down first and foremost, thus extending the life of the cable drag chain.

The new MP 52.6 features a chain side link thickness of 25 mm (compared to the standard product 16 mm) and an inside chain height of 52 mm. The flexible MP shelving system permits the definition of any internal width from 45 mm to 600 mm. It is designed specifically for heavy-duty tasks in the mid-size performance category where operating loads are increasing due to extra control, data and supply cabling and/or extended travel distances.   The MP 52.6 is designed specifically to handle the resultant exponential increase in tensile.

With a larger print area, a huge capacity of up to 600,000 characters per cartridge and an integrated WLAN and Ethernet interface, the new pictor2 inkjet label printer by Murrplastik sets the standard for colour-based inkjet printing systems. The technical highlight: The pictor2 is the first industrial printer capable of independently measuring the print area, providing you 100% assurance of repeatability and reliability.
Figure 1: The pictor2 high-end inkjet printer, an evolution of the previous pictor model, is the first ever industrial printer capable of independently measuring the print area.

The labelling specialists Murrplastik Systemtechnik, Oppenweiler will be presenting the pictor2 high-end inkjet printer, an evolution of the previous pictor model, at the SPS/IPC/DRIVES 2012 trade exhibition. Razor-sharp and photorealistic quality with 720 dpi and fast printing are features that the pictor2 inherits from its predecessor. Murrplastik’s engineers have developed a new ink specifically for the pictor2. The robust typeface is ideal for use in tough industrial environments. An important additional benefit is the greatly improved range of the ink, with an increase in capacity of up to 50%.
Figure 2: Six polycarbonate labelling mats are fixed on the base plate of the pictor2 and labelled simultaneously within 90 seconds.

The pictor2 is really easy to operate. Six polycarbonate labelling mats are fixed on the base plate and labelled simultaneously within 90 seconds. Different sign types can also be “mixed” on a single base plate. That means that your company can manufacture its entire daily requirement of labelling plates in just a few minutes with virtually no effort. The ACS labelling software can be used to read in design data through CAD interfaces.

With its attractive design and a weight of just 20 kg, the pictor2 is the ideal desktop printer. All in all, the pictor2 is the most economical labelling system for companies with medium to high labelling volumes.

This latest development means cable drag chain systems from Murrplastik Systemtechnik GmbH can now do more than just connect a power, hydrau-lic oil, air, water, gas or steam supply to mobile equipment.

Cable drag chain systems made by Murrplastik Systemtechnik, Oppenweiler (nr. Stuttgart) are a smart solution: they supply mobile equipment with both power and data. Without an “umbilical cord” of this kind – which routes and protects the embedded, flexible cables or pneumatic/hydraulic hoses and ensures that the smallest possible bending radius can be maintained – the equipment’s supply lines would be rendered unusable in no time at all.

Thanks to the innovative skills of engineers at Murrplastik, the impressive utility of the Swabian-produced cable drag chains can now be improved still further. The basic idea couldn’t be simpler: instead of using the chain only on the equipment’s supply side, enhance the system so that it can also be used for waste ducting. Often, such enhancements use tubing made from many kinds of materials, for the suction removal of airborne particulates or welding gas at the workplace. In woodworking, too, waste – chippings and sawdust – very often needs removal by suction. Thanks to the existing modular system, it is now very simple to ensure the safe routing of this kind of suction tubing by using the new Murrplastik brackets attached to the PowerLine range of cable drag chains.

The brackets for suction tubing are either mounted on the frame bridges or (for closed chains) on the plastic or aluminium covers. With open chains, the brackets snap onto the frame bridges. If the chains are equipped with closed covers, then the brackets are bolted onto the covers. Tubing can be attached to the inside or outside bend of the chain. No modifications are made to the chains themselves. Accordingly, the standard shelving systems continue to be usable within the chain: these maintain the proper position of the various services, ensuring lines can move freely but not become twisted. If an application already has cable drag chains installed, then it is also very simple to retrofit the brackets to the system. If a piece of tubing needs replacing, the bracket can be removed and re-attached without difficulty and without needing to open up the chain. Since many different diameters of tubing are available, brackets can of course be supplied in several sizes.

Standard guide channel systems (VAW) from Murrplastik can be used to route the chains. We can supply matching adapters for this scenario, ensuring that the chain and brackets have sufficient clearance.

The new Z3 series of photoelectric sensors is the next evolution of the globally acclaimed Z series of sensors. With the longest in-class sensing distance of 25m, the Z3 series includes a built-in amplifier that greatly improves detection performance and yet retains its ease of use and affordability.

The Z3 series through-beam type sensor has a 25m sensing distance, the longest in its class. This high power provides a significant increase in excess gain, which helps the sensor overcome interference from dust or other fine particles. The Z3 series also provides easy optical axis adjustment thanks to its large spot size with good visibility. Its four element LED also helps reduce beam degradation during long-term use.

The output and stability indicator lights are brighter than conventional models making them easily viewable from any direction.

The diffuse-reflective type features an optimized optical receiver system that minimizes the dead zone in front of the lens. This makes it easier to detect objects with a low reflectivity that pass close to the sensor, even objects with varying heights.

Oriental Motor USA is pleased to announce the expansion of our popular BMU Series brushless DC motor and driver package, now including a 200 W (1/4 HP) package. The 200 W (1/4 HP) brushless DC motor is available in round shaft or geared type with inch or metric output shafts. The 200 W (1/4 HP) package is available with 200~240 VAC Single-Phase or Three-Phase input power. Single-Phase versions coming soon.

The new 200 W (1/4 HP) brushless DC motor produces about 50% more starting torque than the 120 W (1/6 HP) motor and about 30% more continuous running torque, creating significant advantages for adoption into larger load application. The flat speed torque “continuous duty” of the 200 W (1/4 HP) motor is now extended to 3,000 r/min, with a total speed torque range of up to 4,000 r/min.

When combined with a gear head, these advantages become even greater with maximum output torque now capable of reaching 610 lb-in (70 N•m).

Oriental Motor USA is pleased to introduce our latest technology for advanced positioning applications, the AZ Series 0.36° Battery-Free, Absolute Sensor Equipped Motor and Driver package.

The AZ Series offers closed loop control, substantially reduces heat generation from the motor and incorporates a newly developed Absolute Sensor for absolute-type positioning. The new Absolute Sensor operates autonomously, without additional battery back-up or external sensors to buy. The AZ Series driver offers advanced and powerful operational programing and function control through our MEXE02 software (available as a free download). With no additional sensors, high speed return-to-home or restart without homing is possible and even common repeat move functions can be programed into the driver, saving wiring, lowering costs, increasing throughput and saving controller command functions.  

The AZ Series is offered with built-in controller or pulse input type with single-phase 100-120 VAC, single-phase/three-phase 200-240 VAC or 24/48 VDC input. Round shaft motor only type or four different geared types are available as standard product, including our newest Harmonic Planetary gear (HPG) with a center shaft or flange mount. All cables are included. Packages start from $762.

Oriental Motor USA is pleased to announce the BXII Series Brushless Motor and Driver Package. The BXII replaces our popular BX Series and now offers an all new driver incorporating a built-in controller with all the features necessary for speed control, position and torque control.

The BXII Series now provides the highest level of speed control, up to 4,000 r/min with a speed regulation of +0.05% and is available from 30 W up to 400 W, in round shaft, parallel shaft gearheads or the hollow shaft flat gearhead and electromagnetic brake options. The new driver features a digital setting directly on the face of the drive to utilize the built-in speed control, positioning or torque limiting functions with no additional control module required.

The new driver can also work in conjunction with our popular MEXE02 software (free download) or if remote programming is required, our standard OPX-2A control module (sold separately) can be utilized. The BXII Series comes standard with a 3m (9.8 ft) cable included.

The parallel geared type produces up to 610 lb-in (70 N·m) of torque and the hollow shaft flat geared type products produces up to 970 lb-in (110 N·m) of torque. The motor and gears come pre-assembled. Packages start from $753 and available to ship in 5 business days.
