摘　　要：为了改善传统电机调速系统成本高、灵活性差、系统复杂的缺点,设计了一种用89C2051单片机控制可控硅进行电机调速的电路,达到了灵活控制并显示转速的目的.可控硅采用过零检测触发方式,主回路由软硬件协调完成,简化了系统,便于检测和维护.In order to eliminate the shortcomings such as high cost, poor flexibility, and complex systems of the traditional motor speed control system, a design with 89C2051 MCU to control thyristor is used to motor speed circuit to accomplish the purposes of flexibility control and speed indication. SCR is triggered by the way of zero trigger, and the main circuit is harmonized by software and hardware, so the system has the advantages of simplicity, easy detection and maintenance.
