DC Motor Speed Controller Circuit

This motor speed controller uses a single IC LM1014 to control the speed of a DC motor. It senses the increase in the motor-current when the rotation of the motor slows down due to a load. The IC then increases the motor voltage so that the original speed is recovered. P1 potentiometer varies the speed of the motor.
