A Variable Speed Bidirectional DC Motor Drive

Abstract

The ubiquity of DC motor in industrial, and home applications makes it one of the most important components in various categories of machines. The unending demands for automation in appliances productions have led to continuing efforts aimed at advancing simpler, cost-effective, and efficient DC motor drive to take maximum advantage of its performance. A simple but robust bidirectional DC motor drive has been presented in this work. The PWM technique is used to generate pulses signals which are used to vary the speed of the motor. The device is designed to run bi-directionally, and the Hbridge was used to control the direction of the DC motor.
