Abstract

This project is about controlling DC motor direction and speed for buggy. DC motor is one of the easiest motor to control the speed and the direction. For the purpose, brushless DC motor (BLDC) has been used. For the speed controller, speed regulation for BLDC motor is achieved by alternating between low duty and high duty ratios. This new concept helps to reduce the cost and complexity of motor control hardware. Among the different control methods for DC motor armature voltage control method using pulse width modulation (PWM) is the best. Power that applied to motor can be controlled by varying the width of applied pulse and DC voltage applied to terminal of motor. To control the speed of the motor, CCP module will be used in the coding create for microcontroller. Concept of changing the direction is using the H-bridge concept which located in motor drive. Motor drive will rotate the motor in either clockwise or counter clockwise rotation. Direction control can also be achieved by the same microcontroller using slight modifications in its programming language. The combination provides smooth speed control in both clockwise as well as anticlockwise direction. Overall this project can provide higher efficiency and smooth operations control for any industrial plant.
