HELIOS ELECTRIC MOTORS
ULTRA HIGH TEMPERATURE BRUSHLESS MOTORS
Permanent magnet brushless motors (surface mount or interior magnet) to 550 °C (1020 °F) ambient
Synchronous reluctance motors (no magnets) up to and in excess of 550 °C (1020 °F) ambient
Custom designed and built
For geothermal, oil & gas, nuclear, aerospace, and industrial applications
At ultra high ambient temperatures electric motor design is extremely specialized. The thermal and mechanical characteristics of motor materials become critically important. Conventional organic materials, particularly above 240-300 °C, are no longer suitable. Helios motors are deployed in extreme environments. Helios Principal and electromagnetic designer is Dr Richard Strahan, who has twenty years of motor design experience. He was awarded the 2006 IET Premium (best paper) for IET Proceedings - Electric Power Applications. Helios draws upon highly experienced Associates for mechanical design, and electronic requirements. Helios is located in Christchurch, New Zealand.
Helios motors can be designed to operate on the Venusian surface (92 bar, 462 °C, sulphuric acid atmosphere)!
Electromagnetic, mechanical, and electronic design
Construction and testing
Design includes 3D finite element modelling capability. Helios has access to a wide array of laboratory equipment, and workshop and testing facilities. In-house capacity is from prototype to small production run. A custom designed motor can be provided, or a complete motor drive solution including a controller developed in conjunction with an electronics associate can also be provided.
