Samad Power

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 sleeve of the rotor 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.
