PROJECT DESCRIPTION

The main concept of this project is to develop a speed-control system for a DC motor for all four quadrants with the help of a four-quadrant chopper to control clockwise, counter-clockwise, forward brake, reverse brake modes of a DC motor.

The four quadrant operation of the DC motorprovides ultimate solution for industries wherein motors are used as per the requirement of an application or load where they can rotate in clockwise, counter-clockwise directions, and also can apply brakes immediately in both the directions.

The proposed system uses a microcontroller of the 8051 family and rectified power supply. In this system,a motor is interfaced to the microcontroller through an H-bridge driver IC to control the DC motor by a switch as the user presses the button. Seven switches are connected to the microcontroller for controlling the movement of the motor.

The four-quadrant speed control of the DC motor is archived by varying the duty cycles from the microcontroller and changing their polarity with the H-bridge IC by appropriate switch pressing. A speed control feature through a push-button operational provision is also available in this project.

The scope of this project can be further improved by using a high-power electronic device to operate the high-capacity DC motors. Regenerative braking for optimizing the power consumption can also be incorporated.

Q & A
Q:  Which microcontroller is used in this project?
A:  A 40 pin 8051 microcontroller is used in this project.
Q:  What are four quadrant operations?
A:  Four quadrant operation of a DC motor means operating a DC motor in Forward, Reverse, Forward brake and Reverse brake.
Q:  Is any speed control feature available?
A:  Yes, in both the directions speed can controlled using PWM technique
