With our highly qualified design and development team and in-house production capabilities, we offer a wide range of permanent magnet electric motors to give you the maximum flexibility you need from High speed (optimised power) to Low speed (optimised torque).
High Speed PM Motors
Designed for our micro gas turbine application, the current product portfolio includes PM electric motors with a power density of 4.5 kW/kg and a speed of up to 230,000 rpm. Depending on the environmental conditions and customer specifications the rotor’s sleeve can be made from steel alloys or carbon-fibre reinforced plastic. Our most recent product can generate up to 3 kW of power at 170,000 rpm with 90% output efficiency. This product is fully compatible with the requirements of high-speed micro gas turbines that require two-way energy transmission. It’s also suitable for all applications that require high speed, including: micro-CHP, dental-medical, precision machineries, high-performance compressed air ventilators, vacuum cleaners and fuel cells.

Low Speed PM Motors
With a compact size and special rotor structure, this low speed permanent magnet motor offers the possibility of ultra-high torques. Thanks to its unique construction and a torque density of 12N.m/kg, this product is the first of its kind in the PM motor industry. It generates 450 watts at a speed of 200 rpm (torque of 23 nm) with more than 90% efficiency (depending on the operating point).
