摘　　要：为了分析定子绕组流过非正弦电流时,多相异步电机的运行性能,必须了解谐波电流与谐波磁势的关系。对异步电机中的非正弦的谐波电流进行了傅里叶分解,将其分解为基波电流和一系列的谐波电流,然后分别计算各次谐波电流的产生的不同的谐波磁势。通过对五相、十五相异步电机在非正弦供电情况下谐波电流与谐波磁势的定量关系的分析,归纳出谐波电流与谐波磁势的一般关系式,以及各次谐波磁势之间的比例关系。In order to analyse the performance of the muhiphase induction motor with non-sinusoidal currents in stator windings, the relationship between the harmonic currents and the corresponding harmonic magnetic motive force （MMF） should be understood. Fourier analysis was used to resolve the no-sinusoidal waveform currents into the fundamental component and a series of harmonic components. The corresponding MMF of each component was calculated. The relationship between harmonic currents and harmonic MMF was got through analyzing the five-phase and fifteen-phase induction motor.
