A bearingless flux-switching permanent magnet memory machine

A bearingless flux-switching permanent magnet memory machine (BFSPMMM) is proposed, which demonstrates the advantages of good suspension performance and wide-ranging speed regulation. The bias magnetic field radial force generated by motor provided magnet, can flexibly decide whether to adopt a single-phase or two-phase mode conduction according needs levitation in X- Y-directions, so as ensure tracking forces therein. This paper introduces its structure, lays foundation for subsequent establishment an accurate mathematical model BFSPMMM.
