摘　　要：利用PLC控制实现三台电动机共用一台自藕补偿器进行降压启动的系统设计,给出了相关的程序、梯形图、电路图,具有较强的容错能力,并可根据数量不同的电机和容量对程序进行简单修改。设计系统运行可靠。The article shows a design that how to make three electro motors share one transformer step-down started using PLC Control, gives the correlative process, ladder diagram, circuit diagram. The design has strong fault-tolerance ability and can modify easily based on the different electromotor and capacitance. This design system runs reliably.
