Abstract :
The speed control of dc motor is very crucial, especially in applications where precision and protection are of essence. Different methods employing solid-state switches are available for a precise control for speed and protection of dc motor. In this paper, the use of micro controller for speed control and protection of dc motor is presented. The peculiarity of this method is its adaptability to different ratings of motors. Experimental results have been obtained which show the employment of microcontroller for acceleration, speed reversal, and deceleration and over current protection of a dc motor.
