Four Quadrant Dc Motor Speed Control Using Arduino

The project is designed to develop a four-quadrant speed-control system for a DC motor. The motor is operated in four quadrants: clockwise, counter clock-wise, forward brake and reverse brake. It also has a feature of speed control. The four-quadrant operation of the DC motor is best suited for industries where motors are used according to the requirement. They can rotate in clockwise, counterclockwise directions and also one can apply brakes immediately in both the directions. In case of a specific operation in industrial environment, the motor needs to be stopped immediately. In such a scenario, this proposed system is very apt as forward brake and reverse brake are its integral features. Instantaneous brake in both the directions happens as a result of applying a reverse voltage across the running motor for a brief period and the speed control of the motor can be achieved with PWM pulses generated by the Arduino Board. Arduino Development Board is used for this operation. Push buttons are provided for the operation of the motor which are interfaced to the Arduino that provides input signal to it and in turn controls the speed of the motor through a motor driver IC. Speed control feature by push-button operation is also available in this project.
