The four switches are connected to the circuit to control motor movement. A slider switch connected to the circuit is for controlling the alternate direction of the DC motor. A 555 timer is used in the project to develop the PWM pulses needed for speed control. The relays are used to change the polarities of the motor, as well as to apply the brake to the motor. In the regenerative mode, the current is applied to the circuit in such a way that a torque is produced to stop the motor instantaneously.
The control of four quadrants of the DC motor is archived by the variable duty cycles of a 555 timer and its changing polarity with the bridge IC H by appropriate switch pressure. The alternative speed control feature is achieved by a slider switch operation.
This project in the future can be improved by using higher power electronic devices to operate high capacity DC motors. Regenerative brakes can also be incorporated to optimize energy consumption.
