电机寄生转矩产生的原因及削弱办法

The Cause of Motor Parasitic Torque and Its Solutions

主要简述对寄生转矩产生的原因,以实例对电机可能产生的3次谐波、5次谐波、7次谐波和其它谐波进行分析,来避免寄生转矩的产生,并采用斜槽来削弱谐波电动势。

This paper mainly describes the causes of parasitic torque. The 3rd, 5rd, 7rd and other order harmonics, which may produced in motor, are analyzed by the practical examples to avoid the parasitic torque and the skewed slot is applied to weaken the harmonic electromotive force.
