Overview of Bearingless Induction Motors
Mathematical Problems in Engineering, 2014 Bearingless induction motors combining functions of both torque generation and noncontact magnetic suspension together have attracted more and more attention in the past decades due to their definite advantages of compactness, simple structure, less maintenance, no wear particles, high rotational speed, and so forth.

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