Our proposed project puts forward a DC motor four quadrant based controlling system. This allows user to operate the DC motor in four different quadrants:

• Clockwise

• Anti-Clockwise

• Forward Brake

• Reverse Brake

The system is very useful for industrial operation since industries usually require DC motors to operate in all four quadrants for various operational cases. Our system enables to operate motors in all four quadrants. Well most industrial scenarios dc motors are required to run in clock wise as well as anticlockwise motions as and when required. Some scenarios also need the motor to be stopped in its motion. At such times our front braking and reverse braking mechanisms are used.
The instant braking in any direction occurs by applying a reverse voltage across the running motor in a small period. The needed pulses are applied by a 555 timer IC. The motor can be handled by user by the use of push buttons provided on the circuit. The push buttons when pressed operate the motor through driver IC.
