A 40 kW high-speed bearingless permanent magnet (PM) synchronous motor with surface mounted magnets represents the focus of this paper. The rotor suspension system is composed of a bearingless unit that generates torque and suspends magnetically the non drive end (NDE) and a permanent magnet biased...
