A Novel Single Winding Structure and Closed Loop Control of the Suspension Force Vector of Bearingless Permanent Magnet Synchronous Motors

Abstract: At present, because of their advantages of simple structure, low cost, low power consumption and high efficiency, single winding bearingless permanent magnet synchronous motors (SBPMSMs) have become one of the research hotspots in the bearingless technology field. However, a high motional-electromotive force (EMF) is generated by rotor rotation in the single winding, which already has side-effects on the normal suspension force current, and the suspension force response can be delayed. Because the method of do… Show more

“…It needs a single multiphase inverter. In order to generate two magnetic fields with pole‐pair numbers of pm and ps, and pmps=±1, the stator phase currents should be composed of two current systems [15]. One magnetic field can generate the torque to control the rotation of the rotor and another one can produce suspension force for rotor levitation.…”
