主要研究了单双层绕组及不同的极槽配合对分数槽绕组永磁同步电动机性能的影响.通过建立8极18槽、16极18槽、20极18槽的单、双层绕组分布的永磁同步电动机的二维模型,得到绕组分布图.分别进行有限元仿真计算,得到各模型的磁力线分布图、电磁转矩波形、转矩脉动波形、齿槽转矩波形和空载反电动势波形,通过对这些波形的分析得出不同绕组类型与极槽配合对电机性能影响的规律.

This paper mainly discusses the effects on fractional slot/pole PMSM with different winding layers and slot/pole combinations. According to the proposed 2D models of 18 slot/8 pole,18 slot/16 pole and 18 slot/20 pole PMSM with single or double layer windings, the phase winding distribution was obtained.Torque ripple, cogging torque,back-EMF and magnetic field distribution waveforms were obtained by finite element analysis,then the deduction of the effects on fractional slot/pole PMSM performance was studied.
