摘　　要：论述了异步电动机的新型电子软启动器的设计及其原理,提出利用PIC单片机控制集成脉冲触发器TC787A的移相电压来产生6路脉冲触发晶闸管,实现电机的软启动;在电机启动与运行过程中利用单片机对常见电机缺相、过载故障进行循环检测,保护电机.The paper discusses the principle to design a new electric soft starter of three-phases asynchronous electromotor . It proposes utilizing PIC single chip microcomputer to control the phase-moved voltage of TC787A which is a integrate pulse producer in order to produce six pulses which touch off thyristor to realize soft-startup of electromotor. During the process of startup and running of electromotor, the single microcomputer is detecting the trouble of phase-lacked and overload circularly to protect the electrometer.
