Construction of A Pulse Width Modulation, (Pwm) Dc Motor Controller

Abstract

Control is very important in all mechanical systems. Given the very valuable role DC motor play in our everyday life and in industries, there is need for a control system in other to apply them efficiently and effectively to achieve desired goal. This project aim at constructing a Pulse Width Modulation DC motor control, using microcontroller and Arduino Programming Language. The system is powered from a 5v rectified power source which pulse was determined by a potentiometer. The varying pulse width generated by the microcontroller as affected by the DC analogue sensor regulates the speed with which the Motor runs. It also incorporates a Dc drive through which the motor is supplied in a manner that prevents a back EMF. The construction was carried out on a Vero board by soldering each component permanently after testing it temporarily on a bread board. Result shows that output tests confirmed the workability of the construction and can therefore be recommended for use.
