EC 40 Ø40 x 80 mm = 170 W. A Formula for High Power Density.

Every single maxon motor clearly proves how high performance can be packed in a miniature space without efficiency and reliability falling by the wayside; for many years, every day, millionfold. How to fit 170 Watts of power in a Ø40 x 80 mm, palm-sized housing is being demonstrated by the new brushless direct current motor EC 40.

The new EC 40 is characterized in particular by two things; high quality materials and superb technical data. In respect to materials, the motor features a neodymium permanent magnet, stainless steel housing and welded flanges. Even a glance at the technical data implies big things: very flat speed/torque gradient (about 3.7 rpm/mNm), mechanical time constant 2.1 ms, permissible speed 18'000 rpm, and efficiency 89%. The ironless winding offers extra quiet running and high stall torque.

As all maxon motors, the EC 40 can be combined with a multitude of components, such as encoders or gears. As a new member, the permanent magnet brake AB 32 joins the maxon …

CAN DRYING - Secomak Supplies Powerstrip Drying System to Carlsberg

Two Powerstrip complete can drying systems are now in use at Carlsberg’s Northampton site.

Cans of beers are dried at very high speed. The Powerstrips are being used after the pasteurising process, and before packing.

Mild detergent based lubricants used to ease the passage of cans through the conveyor system can become concentrated on can tops due to evaporation of water. If moisture form the pasteurising process is left on the can, cans can then become subject to stress corrosion at the final packaging stage.

To counter the problem, can manufacturers, beverage producers and major supermarkets have jointly agreed a new standard of dryness that ensures that the cans are in optimum condition. Secomak’s Powerstrip systems are the first to be able to perform this function at the high speeds required.

High speed lines require special consideration with regard to the handling of the cans through the drying machine, and positioning of the airknives in relation to the can in order to meet the v…

Drying of Containers in the Food and Drinks Industry - The Future

The modern production lines in the Food and Drinks Industry demand high speed drying which is quiet, energy efficient, reliable and easy to clean and maintain, whilst providing a level of dryness which is a challenge to the laws of aero-thermodynamics and physics.

Any lay-person will understand the drying problems encountered with wet, glazed surfaces in the washing-up process and the dewatering and demisting of vehicle windscreens.

In the industrial process, the time available for these drying operations reduces from minutes to hundredths of a second. With the increase in line speeds there is an increased requirement for a studied approach to container drying – it is now a specialist subject in its own right. Simply trusting to a crude compressed air or blower driven solution will not be enough as drying expectations increase.

An investigation of drying equipment on food and drink lines will show that there are already many different approaches to drying problems. A canning factory may…

Type 80 Iso-Ring

With the Ashcroft® isolation ring, the instrument is in contact with the fill fluid, not directly with the process flow.  Clogging or fouling is never a problem.  The Iso-Ring has a flexible inner cylinder, behind which is the fill fluid.  As process liquid flows through the pipe, it exerts pressure.  The pressure exerted by the fill fluid is then monitored by the instrument-sensing element.  A 360-degree flexible cylinder means no plugging, assuring reliable and accurate pressure readings.  A built-in threaded needle valve is provided as standard.  This permits the removal of a pressure instrument for calibration, repair, or replacement without shutting down the process flow.

Intrinsically Safe Ultrasonic Testers: How Important Are They?

The use of ultrasonic devices for non-destructive testing (NDT) has become more common in recent years as equipment has increased in capability and decreased in price. Ultrasonic NDT devices work by creating a pulse of high-frequency sound, generally in the range of 2.5Mhz to 10Mhz, and then measuring the return, a process that makes it possible to measure and resolve anything from the simple thickness of a material through to corrosion and even weld or flaw inspection. The use of ultrasonic NDT devices is attractive because of their non-invasive nature. They don’t require a plant shutdown to obtain a measurement. However, deploying this kind of device within a hazardous (classified) location has implications for safe use that even NDT inspectors may not be fully aware of.

As briefly outlined above, an ultrasonic device operates by combining the creation of a pulse or series of pulses of sound with measurements of the return of those pulses from target back to device. These pulses and…

Vortex Donates Books to the Kilimanjaro Orphanage Centre

Over the past two years, Vortex employees in the UK and the USA have collected over 6,000 children's books for the Kilimanjaro Orphanage Centre in Moshi, Tanzania.

"It was quite a challenging effort," commented Travis Young, Vice President of Global Business Development. "We originally intended the books to be delivered to a local primary school in Moshi, but we found it difficult to communicate and get support. Luckily we found the great people at the Kilimanjaro Orphanage Centre, as they have tremendous need for books and educational materials."

The Kilimanjaro Orphanage Centre in Pasua was founded in early 2009 by Edward Lazaro responding to the recognized need to provide care and shelter to an increasing population of orphaned children in the Moshi area. The Centre is a registered NGO (Charter #3959) that provides residency care for orphaned children as well as day care and community support for other children at risk.

Miniature LVDT Position Sensors Provides Highly Accurate Position Feedback in Robotic Applications

The compact size and highly accurate output of Macro Sensors CD 375 Series of miniature LVDTs make the linear position sensors ideal for providing displacement feedback in different robotic applications.

Robots and robotic arms rely on sensors to determine range of motion or force applied to an object. Attached to a robotic arm, the Macro Sensors miniature LVDT linear position sensors detect position change when an actuator moves the robotic arm, providing an analog voltage signal, proportional to the amount of motion, to a controller that makes appropriate adjustments based on programmable set points. With the data provided by the sensor, the controller can determine when the robotic arm should stop or slow down. For example, on a pick and place machine, if the robotic arm exceeded its travel distance, it could drive right through the board it intended to populate. Macro Sensors miniature linear position sensors evaluate the robotic arm movement for optimum performance.

In addition to…

Macro Sensors Subminiature LVDT Linear Position Sensor Serves as Critical Component in Ophthalmic Ultrasound System

The MD 188 Series Sub-miniature LVDT Position Sensor serves as a critical component of a probe within an ophthalmic ultrasound system used to image the eye and tissues around and behind the eye to determine the presence of pathology.

The Eye Cubed™, manufactured by Ellex Innovative Imaging (, a global leader in the design and manufacture of ophthalmic laser and ultrasound systems used by ophthalmologists to diagnose and treat eye disease, uses sound waves to penetrate into an “opaque media” eye for examination when doctors are prohibited from viewing pathology directly due to an opacity of the cornea, lens or the vitreous gel that fills the eye. The Eye Cubed is used in conjunction with CT or MRI for imaging orbital tumors, optic nerve abnormalities, and to locate 'foreign bodies' that get lodged in the eye or orbit from accidents.

Renowned for its unparalleled sensitivity and highest-quality image resolution, this diagnostic ophthalmic ultrasound technology featu…

Inline Ultrasonic Mixing of Oil and Methanol

Ultrasonic mixing reactors replace tank agitators and other dynamic shear mixers. The ultrasonic reactors are generally installed to mix two feed streams. Oil and methanol (with catalyst). For this, a crude pre-mix is pumped into the ultrasonic reactor, where the ultrasonic cavitation mixes and emulsifies both reagents within 5 to 15 seconds. This is an inline mixing process.

When the mix exits the flow cell reactor, the glycerin will separate by gravity within less than 60 minutes. Alternatively, you can feed the mix into a centrifuge after several minutes of residence / reaction time. The inline mixing reduces the number and volume of tanks used for conventional batch processing. This improves capital utilization.

Lower Material Costs and Boost Biodiesel Yield

Excess methanol and catalyst are significant cost factors in biodiesel production. Hielscher ultrasonic reactors add cavitational shear to the mixing process. This gives you much smaller methanol droplets resulting in improved methanol and catalyst utilization. Therefore, less methanol and catalyst are required. In addition to that, the cavitation influences the reaction kinetics, leading to faster and more complete transesterification.

Full Scale Industrial Biodiesel Reactors

For industrial processing biodiesel production plants Hielscher offers the UIP4000, UIP10000 and UIP16000. These ultrasonic processors are designed for the continuous processing of high flow rates. The UIP4000 and UIP10000 can be integrated into standard sea freight containers. Alternatively, all three processors are available in stainless steel cabinets. The upright installation requires minimal space. Below you find recommended setups for typical industrial processing rates.
