DC Motor Controller Using PWM
Abstract
DC Motor Controller Using PWM project is developed for the
users to control the operation of a DC motor using Microcontroller PIC16F73. It consists of a key pad and microcontroller unit. The key
pad consists of keys to increase and decrease the speed and to change the
direction of the motor.
In a DC motor, there are two terminals called positive and
negative. If voltage is given to DC motor, the motor runs in a particular
direction and if the polarities are reversed, the motor runs in opposite
direction. This project uses a Pulse width modulation technique to
control the operation of a DC motor.
The main part of this project is microcontroller PIC 16F73.
The microcontroller generates different PWM pulses. The user can change the
pulses through key pad. According to the pulse generated, the microcontroller
sends signal to the driver section. The DC motor is energized through the
driver section(FET Z44).
The user can control the speed as well as direction of the
DC motor. The microcontroller program is written in assembly language
