一种低谐波绕组设计方法

A Design Method of Low Harmonic Winding

电机的绕组设计对于实现电机系统节能减排意义重大。首先梳理了若干提升电机效率的定子绕组连接方式,集中研究其中的不等匝低谐波绕组,再结合现有方法提出新的低谐波绕组设计方法,最后利用由此方法得出的方案计算绕组系数,验证谐波含量有大幅降低。

The winding design of the motor is of great significance to the realization of energy saving and emission reduction of the motor system.Firstly,several stator winding connection methods for improving motor efficiency were summarized,and the unequal turn low harmonic winding was studied.Then,combined with the existing methods,a novel low-harmonic winding design method was proposed.Finally,the solution obtained by this method was used to calculate the winding coefficient and it was verified that the harmonic content was greatly reduced.
