非正规定子绕组的谐波分析

Harmonic wave analysis of the non-normal stator winding

为解决定子绕组采用非正规排列的电机的谐波分析难题,以单个线圈为基础,对定子采用非正规排列的异步机的绕组谐波进行分析,推导出每相绕组谐波的分布系数、绕组系数的计算公式,进而导出绕组谐波的三相综合分布系数和三相合成磁动势等相关参数的表达式,并通过计算机辅助设计系统给出非正规异步电机的谐波分析结果和转矩-转差率曲线.

It is difficult that analysis of harmonic waves of the magnetic motive force of non-normal winding is carried out. This paper presents a detailed analysis on harmonic waves of the magnetic motive force of non-normal winding based on the single winding, the calculating formulas of the parameters such as the distribution coefficient and winding coefficient, of per-phase coil were deduced, and furthermore the calculating formula of the parameters such as the distribution coefficient and multi- phase synthetic magnetic motive force, of 3-phase integration was deduced. The result of harmonic analysis of non-normal winding and the torque-slip curve of motor were given by computer aided design system.
