Hysteresis Bearingless Slice Motors with Homopolar Flux-biasing. [PDF]

open access: yesIEEE ASME Trans Mechatron, 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 ...

A 5‐degrees of freedom hybrid excitation bearingless motor for vehicle flywheel battery

open access: yesElectronics Letters, 2021
To deal with the restriction of vehicle space on a flywheel battery, a 5‐degrees of freedom (DOF) hybrid excitation bearingless motor (HEBM) was proposed. The 5‐DOF suspension force required for the flywheel battery is provided by HEBM.

Research on the Influence of Multi‐Harmonic Magnetic Field on the Stability of the Radial Suspension Force and Electromagnetic Torque of Bearingless Motors

open access: yesIET Electric Power Applications
Bearingless motors can realise the rotor active suspension by the radial electromagnetic force, whereas the suspension force and torque ripple will increase the difficulty of motor control, which may lead to the stator and rotor collision and ...

Mathematical model of a novel 12/14 conical bearingless switched reluctance motor

open access: yesEnergy 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 ...
