WIRELESS SPEED CONTROL OF DC MOTOR USING MICROCONTROLLER

Abstract

Direct Current (DC) motor has already become an important drive configuration for many applications across a wide range of powers and speeds. The ease of control and excellent performance of the dc motors will ensure that the number of applications using them will continue grow for the foreseeable future. The aim of developing this project is to control the speed of DC motor. In this project the classical technique control which is PI controller has been studied for servo application to drive the system or loads to control speed and torque. To achieve the speed control an electronic technique called pulse width modulation (PWM) is used which generates high and low pulses. These pulses vary the speed in the motor. For the generation of these pulses a microcontroller (atmega16) is used. The PWM signal will send to motor driver to vary the voltage supply to motor to maintain a constant speed.During this project a wireless system amplitude shift keying (ASK) is going to be used to enhance the dc motor operated manually. This system will actually adapt the requirements of the modern technology. With the help of this system one can control the speed of the dc motor controller from remote sites. It can also control the direction of the dc motor. This project is practical and highly feasible in economic point of view, and has an advantage of running motors of higher ratings. This project gives a reliable, durable, accurate and efficient way of speed control of a dc motor
