Abstract

Direct current (DC) motor has already become an important drive configuration for many applications across a wide range of powers and speeds. The ease of control and excellent performance of the DC motors will ensure that the number of applications using them will continue grow in future. This paper is mainly concerned on DC motor speed control system by using microcontroller PIC 16F877A. The objective of developing this project is to control the speed of DC motor. The main advantage in using a DC motor is that the Speed-Torque relationship can be varied to almost any useful form. To achieve the speed control DAC is used which generates voltages gradually according to microcontroller digital pulses. These voltages vary the speed in the motor. This project can be used in automation field where it is needed to control the speed and direction of a dc motor.
