Abstract

A novel parallel permanent magnet flux-switching motor with trapezoidal back EMF is presented in this paper. This structure inherits the advantages of flux-switching motor, e.g. salient and robust rotor, strong flux-weakening capability and also has superiority in high speed sensorless control for its trapezoidal back EMF like brushless DC (BLDC) motor. Based on motor topology, this paper makes a detailed analysis on the motor flux-linkage and back EMF and focuses on comparing the performance of the motor with different stator and rotor pole numbers. The results of comparison are confirmed by finite element and MATLAB simulation.
