Homopolar, Flux-Biased Hysteresis Bearingless Motor
Described is a bearingless motor based upon a homopolar flux-biased magnetic bearing for force generation and a hysteresis motor for torque generation. The bearingless slice motor levitates and rotates a ring-shaped rotor made of a semi-hard magnetic material. The rotor is biased with a homopolar permanent-magnetic flux, on which 2-pole flux can be superimposed to generate suspension forces. Torque is generated by a hysteretic coupling between the rotor and a rotating multi-pole stator field.
