摘　　要：针对异步电动机因缺相运行而频繁烧坏的现象,通过优化电动机磁力起动器的工作原理和保护功能,杜绝了该现象的再发生,降低了设备故障率。In view of the phenomenon of frequent burn out of the asynchronous motor due to default phase operation,it is eliminated by optimizing the working principle and protection function of the magnetic motor starter. The equipment failure rate is reduced.
