Tech collaboration blowing wind turbines into the next generation
Oxford University Innovation and IEMS collaborate on energy efficient electric generators for wind turbines to get the most out of wind power.
Oxford University Innovation (Hong Kong) and Australia’s Intelligent Electric Motor Solutions (IEMS) today announced the launch of the Torrent Technology for Wind Generators (TTWG) series of energy efficient electric generators.
Large-scale wind generators have become firmly established as a key source of renewable energy sources, and are a central part of any future energy strategy. However, until now, the market for smaller domestic or community scale wind turbines (up to 5kW) has been limited due to the poor efficiency and performance of small-scale wind generators.
The launch of the TTWG series marks the next phase of development of Intelligent Electric Motor Solutions, a company founded on award winning technology from Australian electric motor and generator experts. In order for small wind turbines to become economically viable and complement the environmental impact of larger turbines, they must become more efficient – efficiency that the TTWG series is bringing to market.
Dr David Baghurst, Managing Director of Oxford University Innovation (Hong Kong), said:
“Most conventional electric generators are built from 2D laminated structures that limit power density and efficiency. IEMS generators use soft magnetic composites or SMC’s that they process into more compact 3D designs offering higher power density and higher efficiency. The clever part is the way IEMS have developed the design, manufacturing and assembly operations together so that cost effective highly efficient generators can be produced for a wide spectrum of applications when compared to competitors”.
David Gehlert, Director of Intelligent Electric Motor Solutions, added:
“To achieve high level of efficiency in small generators we usually work to match the generator and controller combination for the specific turbine application. Our design team has developed a suite of modular components and works closely with clients to provide them with an optimised solution. In addition to energy efficiency, other advantages of our designs include efficient operation at very low wind speeds, elimination of cogging giving greater stability, better heat distribution and much smaller size/weight.”

Energy Efficient electric motors from IEMS
Isis 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).
Isis Innovation (Hong Kong) and IEMS today announce the launch of the Torrent TechnologyTM Series of energy efficient electric motors. The launch of the Torrent TechnologyTM 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 TechnologyTM 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 Isis 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 TechnologyTM Series is available to selected parties through Isis Innovation.

Novel materials produce small motors with 90% efficiencies
(article by Drives and Controls Magazine)
Australian researchers have used novel magnetic materials to design and build small motors with energy efficiencies of up to 90%, compared to 60-70% for conventional designs. The new motors are also smaller in size for a given power output.
The researchers, from the University of Adelaide, are working with an industrial partner, Intelligent Electric Motor Solutions (IEMS).
They have used emerging magnetic material – soft magnetic composite (SMC) – combined with novel production techniques, to form stators suitable for use in motors or generators.
The SMC material consists of iron powder that can be pressed easily into any required shape. It is said to simplify manufacturing and to offer improved design flexibility. The technology can be scaled easily to higher output powers.
“Currently all commercial motors are made by pressing very thin metal sheets of silicon iron together and then stamping out the shape of the stator from the metal,” explains the lead researcher, associate professor Nesimi Ertugrul from the University’s School of Electrical and Electronic Engineering. “This process is wasteful of the metal sheeting, and also limits the best use of available space for the copper wire needed in motors.
“We’ve produced new stators using SMC with no need for machining, no scrap metal and improved space utilisation for copper wire for greater power output,” he adds.
The researchers have developed and patented prototype small motors, using SMC technologies. They say that these machines are achieving energy efficiencies of up to 90%.

The first project resulted in a 2kW motor based on soft magnetic composites. IEMS designed and specified the SMC elements, while the University built a computer-controlled four-quadrant dynamometer testbed using an inline torque transducer.
The SMC-based motors operate at low speeds with high power outputs. Their production costs are expected to be low, and they are aimed at general-purpose applications such as swimming pool pumps.
The research has been funded through two grants from the Australian Research Council. The researchers are now looking for further investment partners to commercialise the technology.
The University researchers are also working with IEMS to develop a low-cost micro wind turbine generator based on the SMC materials. They say that this machine will have a high power density and low cogging torque.

AN Australian motor manufacturer hopes to secure an unfettered portion of the global market with a new moulded electric motor design. Intelligent Electric Motor Solutions (IEMS) is a spin-off company from a manufacturing business with a 77 year operating history and has now been producing electric motors for five years . Like many Australian companies however, IEMS has faced increasing difficulty competing with large-scale production facilities in the US, Europe and Japan, and low cost labour countries, particularly China.
With this impetus, IEMS recently channelled over $1 million dollars into research and development, the company's CEO, David Gehlert told FEN. "The Australian market is being inundated by imports and so we decided we should develop our own product range," Gehlert said. The result was "moulded" motors with enormous commercial potential. The motors have an iron core, constructed in a single step by moulding iron powder into the required shape using a large press. This is a revolution upon the traditional method of stacking hundreds of thin sheets of iron (laminations), one on top of one another. IEMS' moulded designs are an estimated 30-40% cheaper to produce than conventional electric motors and eliminate the scrap material inevitably left over from conventional processes. They also use less copper.
These motors have the inherent benefits of brushless DC variable speed motors, with electronic controllers making them highly efficient. Gehlert said he expected the total efficiency of the power transmissions to be around 90%.
IEMS aims to establish the primary manufacturing capabilities of such high-efficiency, low-cost motors in Australia and is working with the University of Adelaide to optimise the manufacturing rocess.
Researchers at the school of Electrical and Electronic Enginnering are currently testing IEMS' designs with a computer aided test setup and developing faster design tools for future motor configurations.
The project has been supported by a $170,000 Australian Research Council Linkage Grant and IEMS is looking for further financial support from companies in end-user markets. Initial manufacturing targets are for applications in wheel-chairs, golf carts, scooters, electric-assisted bicycles and air-conditioners. The motor has already been used in a car under the University of South Australia's Two Person Renewable Energy Vehicle Project.

Mr Rodney Smith – Chairman – is pleased to announce the collaboration efforts of Intelligent Electric Motor Solutions Pty Ltd and The University of Adelaide – School of Electrical and Electronic Engineering in the awarding of an Australian Research Council (ARC) Linkage Project Grant.
The Research Grant is directed to the:
Innovative Design of Soft Magnetic Composite Brushless Permanent Magnet Motors with Enhanced Characteristics and Manufacturing Advantages for Commercial Applications.
The Chief Investigator for this Grant from the University of Adelaide is Dr Nesimi Ertugrul and he recently stated: “The importance and relevance of R&D in this area relates directly to the poor efficiencies of fixed-speed motors, the manufacturing cost and low efficiency of conventional variable speed motor drive systems, and the increasing demand for, and cost of electricity in industrialized countries. These factors exacerbated by complex stator winding requirements in conventional lamination machines and an excessive defect rate commonly caused by stator winding failures”.
Mr Smith acknowledged the importance that independent, third party validation plays in attracting credible investors and manufacturers into this technology. He said: "Whilst our motor designs have progressed to prototype models, it is the limited low volume manufactured model runs planned in conjunction with the University of Adelaide that will validate the quality and quantity of improvement achievable by this technology".
