开关磁阻电动机的PLC驱动控制

PLC driving control of switch reluctance motor

以OMRON公司的CQM1PLC为基础,结合开关磁阻电动机(SR电动机)的工作原理及电压斩波控制方式,讨论了由PLC构成的SR电动机驱动控制器中有关SR电动机的起动程序、转速切换程序、制动程序、角度位置控制(APC)程序及速度显示程序的设计思想,并给出了三相六拍两步起动的梯形图程序。

On the basis of OMRON company's CQM1-PLC,the work principle of SR motor and the control method of voltage chopper, the design thought of starting program of SR motor's , the speed conversion program,the braking program, the angle position control (APC) program and speed show program were discussed. And the ladder diagram of three phase six clap and of two step starting were given in this paper.
