摘　　要：为了分析研究定子绕组在流过非正弦电流时，多相对称电机的运行性能，必须了解绕组谐波磁动势与谐波电流的对应关系。本文以五相对称绕组为例，在非正弦供电情况下，对对称电机中的非正弦电流进行了傅里叶分解，分解得到了基波电流和一系列的谐波电流，然后计算得到了谐波电流与谐波磁动势的定量关系。在此基础上，把谐波电流与谐波磁动势的对应关系推广到聊相对称绕组，为多相对称电机的设计和性能计算提供基础。The relationship between the harmonic currents and the corresponding harmonic magnetic motive force （MMF） should be learned, with the purpose of analysis on the performance of the multiphase symmetrical motor in the course of stator windings flowing through the non- sinusoidal currents. Take five-phase symmetrical winding as an example, in the case of non-sinusoidal power supply, Fourier analysis was used to resolve the no-sinusoidal waveform currents into the fundamental component and a series of harmonic components, the quantitative relationship between harmonic currents and harmonic magnetic, the corresponding relationship between harmonic currents and harmonic magnetic is extended to be m-phase symmetrical winding, which provides a base for muttiphase symmetrical motor design and performance calculations
