摘要: 利用Maxwell 2D有限元软件,对一台8极内嵌式永磁同步电机(IPM)中转子辅助槽位置、深度和宽度3个参数改变时,对电机齿槽转矩 和波形的影响进行了计算,绘制了3种参数变化与齿槽转矩和谐波含量值变化的关系图,从而可得到最小齿槽转矩及相应最优辅助槽结构参 数,最后分析了辅助槽参数对漏磁系数的影响。

Abstract: Maxwell 2D finite element software was used to calculate the influence of the position, depth and width of the rotor auxiliary slot on the cogging torque and waveform of an 8-pole embedded permanent magnet synchronous motor. The relationship diagram between the change of three parameters, the change of cogging torque and harmonic content was drawn. Therefore, the minimum cogging torque and the corresponding optimal structure parameters of the auxiliary slot could be obtained. Finally, the influence of the parameters of the auxiliary slot on the magnetic flux leakage coefficient was analyzed.

Key words: mechanical and electrical engineering, permanent magnet synchronous motor (PMSM), auxiliary slot, cogging torque, induced electromotive force
