Design and simulation of PWM DC motor speed regulator based on Proteus

This design uses Proteus software to design and simulate for the DC motor PWM speed regulator and get the main control of the motor. This article is designed primarily to achieve DC motor PWM governor of forward, reverse, speed up, slow down, stop and other operations. And it also includes simulation of the circuit and program design. To realize the microcomputer control system, the core part of the entire control circuit in the design is the use of 80C51. In order to achieve realistic and accurate measurement of motor parameters, it is equipped with all kinds of display module, drive module. The overall system is composed of the command module, the photoelectric isolation module and the H module. In the design, the pulse width modulation technique (PWM) is used to change the speed of the motor by changing the duty ratio of PWM. In the design of the overall framework, the integrated circuit module can simplify the hardware circuit, and improve the stability and reliability of the overall system, thereby improving overall system performance through the use of a large degree.
