The main characteristics of an electric drive system are reliability, variable speed, high performance are used due to which it can be easily control. The speed control of dc motor is very important because protection and precision are used . The main aim of motor speed control is its takes signal which represents the required speed and drive the motor at that speed. The easy way to control the dc motor is provided by microcontroller. In this paper, the speed control of dc motor has been investigated by the use of an ATmega8L microcontroller. The high frequency PWM signal is driven by the chopper. This work has high feasibility and accuracy according to economic point of view. The main objective of this system is to achieve a constant speed at an different loading condition.
