MOSFET BASED DC MOTOR SPEED AND DIRECTION CONTROL SYSTEM

The objective of this project is to employ MOSFETs to design a DC motor speed and direction control system. Using MOSFETs as electronic switches, the system can change the direction of the motor by adjusting the power supply's polarity while controlling its speed using Pulse Width Modulation (PWM). The PWM signals and control logic for direction reversal are produced by a microcontroller. Protective circuits are incorporated into the design to guard against harm during polarity shifts. The system's capacity to maintain smooth direction changes and precise speed control under various load scenarios is tested. The project demonstrates a compact, effective, and economical method of controlling DC motors that can be used in robotics and industrial applications.
