Abstract
DC motors are widely used in industrial and domestic applications due to their simple construction, high efficiency, and easy speed control. Speed control of DC motors is an important requirement in automation, robotics, conveyor systems, and electric vehicles. Conventional speed control techniques such as rheostat control or armature voltage variation lead to high power losses and reduced efficiency. Pulse Width Modulation (PWM) provides an efficient and economical method for controlling motor speed by varying the duty cycle of the applied voltage. In this research paper, a microcontroller-based PWM speed control system is proposed. The microcontroller generates PWM pulses which are applied to a motor driver circuit to reg ulate motor speed smoothly. The proposed system offers high efficiency, reduced power loss, and precise control suitable for industrial automation.
