摘要
同步电动机的转速与电源频率保持严格的同步关系 ,只要电源频率不变 ,同步电动机的转速就保持不变 ,使同步电动机在许多领域得到广泛的应用。但同步电动机存在起动困难的缺点 ,使它的应用在很大程度上受到了限制。本文介绍了一种解决大型同步电动机起动的电路 ,详细介绍了起动装置的组成以及起动过程实现。
The speed of a synchro motor keeps strict synchronous relation with supply frequency.If the supply frequency is not changed,the speed of the synchro motor keeps invariant.This makes the sychro motor to be widely used in many fields.There are many shortcomings in difficult starting in the synchro motor.Its application is limited to a great extent.The paper presents a kind of circuit to solve the starting of the high capacity synchro motor,and introduces the formation of the starting device and the process achievement.
