Step motor is a common electro-mechanic actuator, and the related drive and control circuits influence its over and high power transistors, higher reliability, lower cost and more versatile, and it is worth to be promoted. The advantages of stepping motor are regulating-rate, quickly rise-stop, positive-reverse controlling and brake etc by changing the frequency of pulse. The stepping motor opening-ring system is simple, cheap, stability and reliability, therefore its application is very extensive in many realmKey words :Step motor;S7-300PLC;PLC目录1 绪 论 61.1 设计的背景和意义 61.2 步进电机的工作原理 81.3 系统设计的目标 92 步进电机的分类、基本结构 102.1 步进电机的分类.............................................................................102.2 步进电机的基本结构.......................................................................112.3 步进电机主要特点..........................................................................112.4 步进电机在工业控制领域的主要应用情况介绍....................................122.5 西门子 PLC ...
