DC motor speed control is one of the most useful features of the motor. By controlling the speed of the motor, you can vary the speed of the motor according to the requirements and can get the required operation. The speed control mechanism is applicable in many cases like controlling the movement of robotic vehicles, movement of motors in paper mills and the movement of motors in elevators where different types of DC motors are used. The movement speed study of electric motors and of rotation direction is considered an important research because of its primordial roles in many electronic circuits. This project studied how to control the DC motor speed, as well as its rotation direction, by adjusting the pulse width PWM.
