Abstract

This project is aimed to create a device that can automatica1ly control the speed of the motor at the certain speed even thought there is any disturbance. The motor's speed also can be selected in certain speed. There is low, medium and high speed. The PIC (Programmable Interface Controller) is used as a controller to control the speed of DC motor. Optoelectronic sensor will be used to measure the speed of DC motor. In this system, the photo detector sensor was used for measure the rotation speed of DC motor. This system is also can measure the speed of rotation even there is any disturbance occurred in systems. The disturbances could be such as wind, oil or water. When there is any disturbance occurred in system, the PLC will be triggered and control the rotation of motor to the setting speed. The main objective of this project is to design a system with PLC to measure the speed of rotation of DC motor even there is any disturbance occurs in systems. The speed of rotation be detected by using the optoelectronic sensor. This LED will emit a beam of light to rotated disk. The interrupted beam light will be captured by the photo detector and the speed will be measured. The PLC acts as a main part in this projects as it triggers and controls the whole circuit. The PLC controller is controls the speed of rotation. The measured speed will be display in a seven segment display.
