Ultra
High Speed Motor
Working in collaboration with the Gas Turbine designers, Equipmake has developed a high speed motor generator for an electric vehicle range extender application.
The motor has a surface samarium cobalt permanent magnet rotor with a titanium retention sleeve. Equipmake has developed a power electronic inverter to allow the motor to interface to a 350V lithium ion battery pack and interface to the vehicle control system.
The motor runs on greased ceramic ball bearings and has integral air cooling of the stator and rotor.
