PROJECT DESCRIPTION

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

The four-quadrant operation of the DC motor provides ultimate solution for industries wherein motors are used as per the requirement of the application or load. Such motors 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 a rectified power supply. In this system, the motor is interfaced to the microcontroller through a motor-driver IC for controlling the DC motor. The Bluetooth transceiver is interfaced to the microcontroller for communication.

Once a user connects the Android-application device to this system through a Bluetooth, then the user can send the control signals through the Bluetooth attached to this system. The user can also enter the selected speed option on the Android application through the GUI for the corresponding direction by varying the duty cycles from the microcontroller, and changing their polarity with H-bridge IC by appropriate key pressing on the Android application.

This project in future can be improved by using high-power electronic devices to operate high capacity DC motors. Regenerative braking for optimizing the power consumption can also be incorporated in this system.

Q & A
Q:  Which microcontroller is used in this project?
A:  A 40 pin microcontroller from 8051 family 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 it possible to control speed of motor?
A:  Yes, it is possible to control speed at both directions, from 0 to 100% in steps of 10%, using PWM method.
Q:  Can the speed control be done wirelessly?
A:  Yes see model 228 with microcontroller and 241 without microcontroller.
