摘要 为使电动机获得理想的性能,设计每一相绕组的合成磁动势应尽量接近正弦波以抑制谐波降低损耗.本文介绍绕组合成磁动势的基本原理,提出基于Matlab的线圈磁动势谐波分析方法.通过Matlab仿真生成相绕组的合成磁动势,并对磁动势进行傅里叶变换,得到基波与谐波的幅值,为合理的选择节距降低线圈的谐波含量提供依据.以2极,4极的电动机为例进行仿真与试验,仿真结果表明文中方法适用于电动机设计应用.

Abstract:To make the motor obtain the ideal performance, the design of each phase winding's synthetic magnetic motive force should be as close as possible to the sine wave to suppress the harmonics and reduce the loss. The basic principle of synthesis of magnetic motive force and coil MMF harmonics analysis method based on the Matlab are proposed in this paper. Simulation of the force and FFT transform through Matlab are introduced. Get the amplitude of fundamental wave and harmonic wave. Provide the basis for reasonable selection of the pitch and reduce harmonic content of the coil. Taking 2 and 4 pole motor as an example, the simulation and experiment results show that the method is suitable for the design of motor.
