Upgraded AC Motors Make Fiber Spinning More Efficient

Synthetic-fiber producer ENKA de Colombia SA, Medellín, Colombia, replaced dc and ac motors with advanced ac versions coupled to efficient variable-frequency drives on a fiber spinning line. The strategy saves the company more than $883,000 annually in electricity and downtime. The spinning line extrudes nylon and polyester filaments from melted resins. Before the upgrade, motor and drive efficiency was about 50%. Part of the production line used an uninterruptible power supply (UPS) meant for protection from power outages, but the UPS ran at 80 to 93% efficiency at best. One outcome of the inefficiencies was that the old equipment produced enough heat to demand its own a/c system. Elevated temperatures led to more breakdowns and repairs. The new variable-frequency drives, Yaskawa F7 and G7 ac VFDs, have a nominal 98% efficiency. They create so little heat that ENKA was able to remove nine a/c units formerly needed to cool its factory. The new ac motors are also smaller than

XYZ: AC Motors vs. DC Motors for Power Presses

Depending on the drive style, a high-tonnage mechanical press can stamp out metal parts at up to 1,000 strokes per minute. Even so, it’s a remarkably durable machine. The steel frame will long outlive the motor and electronic controls that drive the flywheel. And therein lies a problem. Most mechanical presses built in the 1980s or earlier were powered by DC brush motors. And they are expensive and difficult to replace, retune and maintain. A new DC motor can take weeks to get. Once installed, it must be tuned with potentiometers and jumpers. The process requires considerable tweaking, even if the original motor’s “pot” settings are known. “We have several customers where engineers used a paint marker to note how the potentiometers were set,” says Steve Spero, service engineer with Yaskawa America Inc. “We have other customers where no one knew how they were set, and it can be all sorts of fun turning those knobs to get the motor back in working condition.” To avoid such issues,

Yaskawa Commemorates First U.S.-Manufactured MV1000 Medium-Voltage Drives

Yaskawa Electric Corp. and Yaskawa America Inc. celebrated the start of U.S. manufacturing for the Yaskawa MV1000 in a ceremony at the Yaskawa America Oak Creek, Wis., plant on Nov. 30. Yaskawa offered the medium-voltage drive (for motors up to 5000 hp) earlier this year, but ordering and shipping from Japan takes about 6 months. That’s expected to be reduced to 8 weeks or less after more than $3 million is invested by 2014 for new manufacturing and testing areas in the 30,000-sq-ft plant. By late 2013, models serving up to 5,000 hp are expected to be available, including UL and CSA listings. Yaskawa MV1000 is said to be the smallest 1000 hp drive available, with 30%-60% smaller volume compared to the last generation of Yaskawa product. It also has the longest mean time between failures (MTBF) at 200,000 hours, a number expected to increase, said those involved. Yaskawa Smart Harmonics Technology reduces input harmonics, meeting IEEE519-1992 and eliminating the need for other fil

Han® PushPull Signal: reliable transmission for all important conductors

The new HARTING PushPull Signal connectors meet the demands of industry for the reliable transmission of energy, signals and data in all power ranges, consistently and in a uniform connector system. HARTING PushPull Signal has 10 contacts to transmit rated currents of 5 A with conductor wiring gauges of up to 0.75 mm². To ensure EMC interference immunity, the contact inserts are fully screened, as they are with RJ45 data connectors. Screened cables can be connected. The connectors have PushPull locking for reliable and intuitive connection. Perfect locking is indicated by an acoustic signal (a click). Hybrid applications can also be created with PushPull Signal. For example, one part of a connector face can be used for energy transmission, whereas other contacts are available for communication. PushPull Signal connectors are obtainable in the PushPull 14 and 4 version series in accordance with IEC 61076-6-107. Han® PushPull version 14 is the preferred connector for decentralized

Han-Yellock® 10 connector

In the form of the Han-Yellock® 10, HARTING is now introducing a new, compact connector. Based on the established Han-Yellock® 30 and 60 sizes, functionalities have been adapted to meet the requirements of compact units and systems. Universality and efficiency are the keynotes of the uses the new Han-Yellock® 10 can be put to. Currently with 25 different contact inserts, it meets all needs from energy supply to data transmission. Consequently, one size can reliably transmit power of up to 40 A / 690 V and sensitive data signals, as in Ethernet applications, for example. In addition, multipole varieties with up to 21 contacts are also available. Contact inserts are also possible for optical data transmission. The key features are ease of handling and operation. The locking mechanism integrated in the housing locks both housing halves reliably during the connection process. Unlocking is a similarly intuitive process. A brief push on the activation button is all that is required. The

D-Sub SMT connector: new straight design

HARTING is expanding its product portfolio with the introduction of a new straight D-Sub SMT connector series. This will complement the already globally established angled D Sub SMT range.  The optimized design allows for easy handling and a long working life. The new series is compatible with other surface mount components which results in a simplification of PCB design and manufacture and opens up new application opportunities. 100% co-planarity is achieved by combining stamped contacts with our uniquely designed insulator. This concept provides a robust solution capable of effortlessly withstanding all stresses encountered during normal assembly procedures. The straight D Sub SMT connector is available in two mounting formats, with flat grounding pads or with the addition of two PIHIR pins for an increased retention performance. The black insulator ensures good positional camera recognition and the two plastic locating pins included in the molding prevent the connector moving fol

Han-Quick Lock® Termination Technology

Since its launch, Han-Quick Lock® termination technology has found a firm footing in the market and is installed in numerous HARTING products. The new feature is that most connectors are available for two wire gauge ranges. This is shown by the different coloring of the Han-Quick Lock® actuators. The termination wire gauge ranging from 0.25 mm² to 1.5 mm² has a black actuator, whereas the actuator for the 0.5 mm² to 2.5 mm² range is blue. The innovative termination technology makes it possible to connect a stranded wire to a connector contact without having to use any special tools such as a crimping tool. The contacts are already pre-assembled in the connectors with Han-Quick Lock®. With its space-saving design, the patented termination technology boasts very high contact density, making it ideal for integration in various types of connectors. For example, many HARTING connectors are available with two alternative termination technologies, though of course they are still mutually

Han® Q 3/0 and Han® Q 4/0 connector

With the Han® Q 3/0 and Han® Q 4/0, HARTING is expanding its portfolio in the smallest Han® 3A size range. An area measuring 42 mm² is enough room for 3 power contacts and the protective earth contact (Han® Q 3/0) or 4 power contacts (Han® Q 4/0). This makes them both the most powerful in the compact industrial connector class. The connector boasts the following performance data: clearance and creepage distances with the Han® 3/0 allow a 400 V rated voltage, which increases to as much as 830 V with the Han® Q 4/0. Both have roughly similar current load capacities – this is approx. 40 A given an ambient temperature of 40°C and a connection wire gauge of 4 mm². Because connectors with standard Han® C contacts can be used with a wire gauge of up to 10 mm², currents of over 80 amps are possible but in these cases the diameter of the cable entry need to take into account. Both connectors are used in industrial environments. They are ideally suited to the needs of the semi-conductor i

HARTING har-link®: Now also with solder bucket contacts

HARTING is expanding its space-saving har-link® metric product range with a version equipped with solder bucket contacts. Up to now, connectors were supplied on the cable side only with an insulation displacement termination. The new har-link® with solder bucket contacts now enables fast and easy harnesses prototyping for test purposes for example without the use of a special dedicated tooling. With this new contact style, now wires from the AWG 30 up to the AWG 24 can be mounted on the cable side of the har-link® connection, providing a high flexibility and compatibility with a large range of cables available on the market.

har-flexicon®: tool-free individual conductor wiring with 1.27 mm spacing

The HARTING Technology Group is creating new standards in the PCB field with har-flexicon®, the new miniaturized and field-assemblable individual conductor connection technology with 1.27 mm spacing. Flexible individual conductor wiring of industrial devices with PCBs as their key component is one of the principal requirements in modern device technology – and it will always stay that way. Because sensoric and actoric subassemblies need to be connected on site rapidly, PCB connection technology must continue to be universally applicable. What is required is flexibility in the connection of I/O signals with tool-less individual conductor wiring – which enables on-site assembly in the field. It is always the overall, not the individual, costs of components which are paramount in the development of industrial subassemblies. The use of reflow and SMD solderable components in automated assembly and soldering processes leads to manufacturing costs which are lower than those for the manu

har-flex®: Compact, versitile and rugged

HARTING's har-flex® product family connectors with 1.27 mm contact pitch are expanding the design options for industrial devices.

All har-flex® connectors are available with from 6 to 100 contacts, in increments of two. In addition to the connectors for flat ribbon connection, HARTING also offers assembled cables. The compact but rugged design of har-flex® also guarantees reliable operation under adverse conditions. Two large holders ensure that the connectors are firmly held in place after the soldering. A low-wear insertion and withdrawal procedure is achieved by a very smooth con

Energy management at HARTING

HARTING has successfully tested energy data acquisition with smart Power Networks in its own production area. Now the company is presenting the application at this year’s SPS in Nurnberg. HARTING has created its own software for data handling and data visualization. The HARTING solution provides users with the necessary energy flow transparency, which represents the foundation for energy policy decisions. Data transparency is therefore the first step for successful energy management. HARTING has consequently created the database that ISO 50001 demands.  The acquired transparency is consulted for the analysis and then transferred into actions for improvement. The company operating a machine or system consequently gains an insight into the state of the machinery and is able to identify energy peaks, form operating figures, control the consumption depending on the energy costs and prepare benchmarks for individual machines.

RFID-sensor combination

RFID technology makes it possible to identify goods and substances with the help of electromagnetic waves within certain frequency ranges. HARTING regards UHF RFID technology as the right choice for the transportation, automation, machinery and energy markets. This technology stands up to the harsh environmental conditions that prevail in these markets and also reliably registers rapidly moving objects with metal surfaces, such as railway cars. A read range of from 5 cm to 12 m ensures the greatest flexibility for the applications. Thanks to its special patented transponder properties, the HARTING portfolio is optimally suited for these conditions. The High Performance Reader, which is capable of registering and processing more than 300 transponders per second, is joined by a selection of reading antennas. These allow HARTING to offer modular solutions for the widest range of applications in the RFID field. In the age of the "Internet of Things" in which goods or even li
