DC motor Direction control circuit in Proteus | Project file available for download
Speed and direction control of DC motor is always a crucial process. This looks simple but when this
comes to applications it has to be more precise and accurate. The speed and direction in mainly applied in stator motor
and wiper motor of 2 wheelers apart from that it is also used in many paper mills, printing machine tools and cranes.
There have been previously many researches with speed and direction control in a single circuit or separate circuit. The ultimate objective of this project is to design a cost efficient, precise and compact circuit for speed and direction control of DC motor without the use of microcontroller. Designing a circuit without microcontroller will reduce the cost also overcomes other drawbacks like limited range. This circuit has used transistorized H-Bridge for controlling the direction and 555 Timer for controlling the speed. By adjusting the duty cycle by means of Pulse Width Modulation is the basic principle in the speed control of DC motor.
