CONTROL OF DC MOTOR BY USING MICROCONTROLLER

Abstract

The Electric Motor System (EMS) is used widely in different industrial, agricultural and mining applications. However, the speed of the DC electric system is a very vital factor in accomplishing the tasks effectively. This study tries to find out the most effective way of achieving an electric motor system with a regular speed at any load. A microcontroller ATmega16 used to control the speed of the EMS using the DC motor .The microcontroller ATmega16 sends signals to the DC motor, which equal to the motor terminal voltage, and in turn the DC motor drives at speed according to the amount of the signal received from the microcontroller. is It found that using the microcontroller ATmega16 provides three levels of stable speeds, and can be seen on display screen LCD. This result is of economical value because it reduces energy consumption and operation time.
