摘要
简要分析了分数槽永磁同步电动机电枢磁场的谐波,利用Maxwell 2D有限元分析软件分别仿真计算了36槽30极、32极、34极三台永磁同步电动机的永磁体磁场,通过傅里叶分解得到永磁体磁场的各次谐波及幅值,进行了径向力波分析。通过径向力波分析结果确定最佳的槽极配合,同时分析了不同极弧系数对永磁同步电动机齿槽转矩的影响。此分析方法对永磁同步电动机的优化设计具有一定的参考价值。
Harmonic of armature magnetic field of fractional-slot permanent magnet synchro- nous motor （PMSM） was briefly analyzed. Simulation calculations for magnetic fields of perma- nent magnets of three PMSMs with 36 slots and 30,32,34 poles were respectively carried out by finite-element software of Maxwell 2D. Various order harmonics and amplitudes of magnetic fields of permanent magnets were obtained by Fourier decomposition, and radial force waves were ana- lyzed. The optimal slot/pole combination was confirmed based on analysis result of radial force wave, and the influence of pole-arc coefficient on cogging torque of PMSM was analyzed simulta- neously. The analysis method in this paper has a certain reference value in optimal design of PMSM.
