Abstract

A 12/10 flux-switching permanent magnet motor (FSPM) is described. Qualitative analysis of magnetic circuit indicates that a connection between stator segments is benefit to motor operation. From the basic principle of flux-weakening speed-extension operation, weaken magnetic factor and speed-extension multiple are calculated. The analysis results show that this kind of motor has higher flux-weakening capability than that of other general permanent magnet motors. According to finite element analysis, influences of changing permanent magnet width, air-gap length and rotor-tooth width on flux weakening capability are studied. The results lay an instructive significance for further development of FSPM.
