PROJECT DESCRIPTION

The project is designed to control the speed of a DC motor using a PIC16F8 series microcontroller. Speed of the DC motor is directly proportional to the voltage applied across its terminals. Hence, if voltage across motor terminal is varied, then the speed can also be varied. 

This project uses the above principle to control the speed of the motor by varying the duty cycle of the pulse applied to it (popularly known as PWM control). The project uses two input buttons interfaced to the microcontroller, which are used to control the speed of motor. PWM (Pulse Width Modulation) is generated at the output by the microcontroller as per the program. The program can be written in Assembly language or in Embedded C.

The average voltage given or the average current flowing through the motor will change depending on the duty cycle (ON and OFF time of the pulses), so the speed of the motor will change. A motor-driver IC is interfaced to the microcontroller for receiving PWM signals and delivering desired output for speed control of a small DC motor. 

 

Furthermore, the project can be enhanced by using power electronic devices such as IGBTs to achieve speed control higher capacity industrial motors.
