逆变器驱动异步电动机的稳定性分析

Analysis of Stability of the Asynchronous Motor Driven by a Inverter Inverter Fed Induction Motor

从电动机角度分析了逆变器驱动异步电动机的稳定性，得出电动机在低速、轻负荷状态下不稳定的原因是受定子电阻Ｒ１影响的结论。

According to the electric principles of the induction motor,this paper discusses the stability of the motor driven by a inverter,and presents the result that,when motor′s load is light and the motor is driven by a inverter at lower speed,the stability of the motor running will be influenced by its stator resistance.
