Optimal Design of Flux-Switching Permanent Magnet Machine Based on Finite Element Analysis

This paper investigates the optimal design of a 12/10-pole flux-switching permanent magnet (FSPM) machine based on finite element analysis, including two parts. Firstly, the optimal rotor pole arc to alter the waveform of phase back EMF more sinusoidal is obtained. Secondly, the optimal dimensions of the machine, namely, stator pole width, rotor pole width, PM thickness in magnetization direction, and split ratio (the ratio of stator outer diameter to inner diameter), are obtained to produce the maximum torque under the same copper loss
