Abstract: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.
