摘要
文章论述了利用改变晶闸管的触发角来调节异步电动机定子两端电压,进而改变电机的转速和定子电流的软起动的原理。这种软起动方式结构简单,性能好,调试容易,对于要求不高的风机、泵类负载非常适用。
This article discusses the use of Thyristor firing angle changed to adjust the voltage across the induction motor stator, thereby changing the motor speed and stator current soft start works. This soft-start mode structure is simple, excellent performance and is easy to be adjusted. For less demanding fan and pump load is very applicable.
