Influence of MainWinding Connection on Vibration and Acoustic Noise of Bearingless Switched Reluctance Motors

摘要：

Fundamental principle and control strategy of main winding square-wave current of bearingless switched reluctance motors are introduced. Since rotor eccentric exists when operation of BSRM, influence of eccentric on air-gap flux distribution with different main winding connections is analyzed. As pulsation of radial force is origin of vibration and noise of SRM, a radial force mathematic model is introduced considering magnetic saturation. Winding currents are different with different main winding connections even under the same load, thus radial forces of stator poles are different. Influence of main winding connections on vibration of stator is researched and the conclusion of all parallel of main winding coils is in favor of vibration reduction is draw.
