摘要
单相异步电动机往往采用电容分相的方式,方便电机启动和正反转控制。然而,传统的单相异步电动机驱控电路,无法兼容两端子和三端子引出的单相异步电机,且往往仅针对单台电机,无法自行扩展,模块化层次较低。为此,该文设计了一种单相异步电动机驱控系统,其主控模块采用MCU微处理器,负责多台电机总电源的供电和总控;分控模块集成电机控制电路,用于实现单个电机的正反转控制、电流监控、调压调速等功能。其与主模块采用可扩展接口连接,根据所带电机数量的不同,合理扩展分控模块,即可实现电机数量的扩展,且分控模块的电机接口端子,可以通过简单的短接,实现多种单相异步电动机的兼容。
Single-phase asynchronous motors often use capacitor phase separation to facilitate motor starting and forward/reverse control of drive control circuit.However,traditional single-phase asynchronous electric motor drive control circuits cannot accommodate both two terminal and three terminal single-phase asynchronous motors,and are often only applicable to a single motor,unable to expand on their own,resulting in a low level of modularity.Therefore,this article designs a single-phase asynchronous motor drive control system,whose main control module adopts STM32 microcontnller,responsible for the power supply and overall control of multiple motors.The sub control module integrates motor control circuits,which are used to achieve functions such as forward and reverse control,current monitoring,voltage and speed regulation of a single motor.It is connected to the main module through an expandable interface.Depending on the number of motors carried,the sub control module can be reasonably expanded to achieve the expansion of the number of motors.The motor interface terminals of the sub control module can be easily short circuited to achieve compatibility with various single-phase asynchronous motors.
