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

Abstract 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. The use of a permanent magnet to provide a suspension...
