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...

| description | 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 bias magnetic field reduces power consumption. The relationship between the torque and suspension systems is weak coupling, which is beneficial to the decoupling control. To verify the aforementioned advantages of HEBM, its topology and principle are introduced, and its electromagnetic characteristics are analysed by finite element method. The HEBM is compared with the single‐winding bearingless switch reluctance motor by focusing on suspension loss and force density. |
