Energy Efficient electric motors from IEMS
9th March 2015
Oxford University Innovation (Hong Kong) is pleased to announce the launch of the Torrent Technology Series of energy efficient electric motors by portfolio project company Intelligent Electric Motor Solutions (IEMS).
Oxford University Innovation (Hong Kong) and IEMS today announce the launch of the Torrent Technology TM Series of energy efficient electric motors. The launch of the Torrent Technology TM Series of brushless permanent magnet electric motors marks the next phase of development of IEMS, a company founded on award winning technology from Australian electric motor experts.
Electric motors are widely used in all kinds of applications. For example, about 45% of the world’s electric energy is used by motors with pump applications representing 20% of consumption. However, the biggest issue is with smaller electric motor-based products (100W – 5kW) as they offer very low combined system efficiency. This lack of efficiency is a huge cost both financially and environmentally.
As energy saving is becoming an increasingly important selection criterion for consumers to achieve the highest operating efficiency, Torrent Technology TM aims to develop future electric motors and drives not in isolation to achieve significant energy saving opportunities specifically in pumps. For example, while the total system efficiency of a small variable speed pump system can be as low as 22% (assuming a pump efficiency of 40%, a motor efficiency of 70% and an inverter efficiency of 80%), the total system efficiency can be greater than 49% (assuming a pump efficiency always above 60%, a motor efficiency of 90% and an inverter efficiency of 90%) in a matched high efficiency inverter/motor/pump unit and an adaptive control system.
The same technology can be applied to many other motor drive applications, as the energy utilisation is highly critical in any domestic or industrial products.
On the novelty of the IEMS approach to motor design, Dr David Baghurst, Director of Oxford University Innovation (Hong Kong) explains: “Most conventional electric motors are built from 2D laminated structures that limit power density and efficiency. IEMS motors use soft magnetic composites or SMC’s that they process into more compact 3D designs offering higher power density and efficiency. The clever bit is the way IEMS have developed the design, manufacturing and assembly operations together so that cost effective highly efficient motors can be produced for a wide spectrum of motor applications when compared to competitors.
On overall system design David Gehlert, Director of IEMS says: “To achieve high level of efficiency in small motors we usually work to match the motor and controller combination for the specific end application. Our design team has developed a suite of modular components and works closely with clients to provide them with an optimized solution.”
The target markets for the motors include:
· Integrated seal-less inline pump
· Swimming pool pumps
· Engine cooling pumps
· Submersible pumps
· Air circulation air conditioning, heating fans
· AC and DC powered refrigerator compressors
· Production line/conveyor belt motors
· Servo motors
· Low cogging torque wind generator
Isis is keen to talk to companies interested in obtaining samples of the motors and testing them for this broad range of applications. The motors meet and exceed the new IEC normative efficiency classes of IE5 super premium efficiency motors and can be utilized in variable speed modes in the range 0-4000 rpm.
A brochure including technical specifications of the Torrent Technology TM Series is available to selected parties through Oxford University Innovation.
