摘　　要：电力拖动自动控制设备的控制对象为各类电动机或其他执行电器,控制原理为通过对控制对象的起动、停止、正反转、调速、制动等的运行方式采用电气控制的方法实现控制,进而在生产过程中实现自动化控制。为了更好地控制电动机的运行,需要设计相应的控制线路。从逻辑代数的基本概念入手,探讨逻辑代数在设计三相异步电动机控制线路中的应用,针对三相异步电动机连续运转和正反转控制线路设计进行详细介绍。The control objects of electric drive automation control equipment are all kinds of motors or other executive electrical appliances,and its control principle is to use electrical control methods to control the operation modes of control objects,such as starting,stopping,positive and negative rotation,speed regulation and braking,and then realize automatic control in the production process.In order to better control the operation of the motor,it is necessary to design corresponding control circuits.This paper starts with the basic concept of logic algebra,discusses its application in the design of control circuits for three-phase asynchronous motors,and introduces the design of the continuous operation and forward-reverse control circuits of three-phase asynchronous motors in detail.
