基于PLC的步进电动机控制系统研究

摘要

According to working principle and control method of stepper motor, the design scheme of the control system of stepper motor is discussed. Micro PLC of SIMENS is chosen as controller to work out the control system of stepper motor. Multiple control modes including speed, direction, three-phase three steps and three-phase six steps can be implemented in the control system. The control system is simple, functional, high reliability.%依据步进电动机的工作原理以及控制方法，提出了步进电动机控制系统的设计方案。使用西门子CPU224可编程控制器作为核心控制器设计出步进电动机控制系统，可以实现对三相步进电动机速度、正反转、三相单三拍、三相六拍等多种运方式的控制。给出控制系统软硬件的实现方法，整个控制系统结构简单，功能较强，可靠性高。
