Hysteresis Bearingless Slice Motors With Homopolar Flux-Biasing [PDF]
IEEE/ASME Transactions on Mechatronics, 2017 We present a new concept of bearingless slice motor that levitates and rotates a ring-shaped solid rotor. The rotor is made of a semi-hard magnetic material exhibiting magnetic hysteresis, such as D2 steel. The rotor is radially biased with a homopolar permanent-magnetic flux, on which the stator can superimpose 2-pole flux to generate suspension ...

Mathematical model of a novel 12/14 conical bearingless switched reluctance motor
Energy Reports, 2022 Aiming at the defect that the traditional bearingless switched reluctance motor cannot control the axial suspension force, so that the rotor cannot achieve five-degree-of-freedom suspension by itself, this study presents an innovative 12/14 conical ...

Self-Sensing Hysteresis-Type Bearingless Motor
, 2022 Bearingless motors use a single stator assembly to apply torque and magnetic suspension forces on the rotor, making these machines compact with frictionless operation and thus well suited to high-speed applications. One major challenge that prevents wide usage of bearingless motors is the need for air-gap position sensors, which are typically expensive.
