电压变化对电励磁同步电动机的影响

Influence of Voltage Variation on Electrically-Excited Synchronous Motor

介绍了同步电动机在三相对称电压下运行时电压变化对电动机的各项性能的影响以及在三相不对称电压下运行时电机的运行状态和产生的危害,通过分析,明确什么情况下是可以短时运行,什么情况下是必须停机检查的,对后续同步电动机的实际使用具有一定的指导作用。

This paper introduces the influence of voltage variation on various performances of synchronous motor running under three-phase symmetrical voltage,as well as the running state and harm of the motor running under three-phase asymmetrical voltage.Through the analysis,it is known that under which conditions the motor can operate for a short time and which conditions the motor must be stopped for inspection.It has a certain guiding significance for the practical use of the follow-up synchronous motor.
