摘要

本研究的目的是预测多相轴向磁通永磁(AFPM)电机在磁体移动和步进时的转矩质量性能。对三相电机、三相电机和七相电机进行了研究，并对两步、三步电机的设计方案进行了分析比较。结果表明，采用三步换档和两步换档的多相电机，转矩脉动均有所减小。就平均转矩而言，磁体步进位移对高相数电机的影响大于对低相数电机的影响。

Influence of Rotor Magnet Step Shifting on Torque Ripple of Multiphase Axial Flux Permanent Magnet Machines

The aim of this study is to predict the torque quality performance of multiphase axial flux permanent magnet (AFPM) machine when magnet shifting and stepping are applied. Three, live and seven phase machines are investigated and design options such as two-step, three-step are compared analytically. It was found that torque ripple is reduced in all multiphase machines with three-step and two- step shifting. As far as the average torque is concerned, step shifting of the magnet has more influence on high-phase number machine when compared with low-phase number machine.
