Abstract: Manufacturing plant in industries like chemical, pharmaceutical, plastic and textiles all need speed variation. And it could be flat belt application, flow management application or combining of liquids. There are different kinds of motors-AC, PMDC, Servo or steppers which are used according to the applications. Of these, PMDC motors have widely used .The PMDC motors are easy to control compare to other types of motors. The treadmill is a walker which is used for exercise. This is one application in which a PMDC motor plays an important role in its operation. The PMDC motors are used to operate these machines. In this paper, implementation of PIC 16F877A microcontroller to change the speed of PMDC motor fed by a MOSFET has been investigated .The MOSFET is driven by high frequency PWM signal .Controlling the PWM duty cycle is same as to control the motor terminal voltage, that changes directly the motor speed. Experimental results are obtained that shows the use of microcontroller for speed management and over current protection of a DC motor.
