DC Motor Heat Protection System

Abstract

This project is developed for the users to protect the motor from over heat. It mainly consists of DC motor, heat sensors, display and electronic parts. Normally DC motors are used to drive mechanical parts in electronic devices. A heat sensor is connected with the body of the motor. The sensor senses the heat and sends signal to a microcontroller. The microcontroller analyses the signal and sends signal to the LCD display. The display displays the temperature of the motor. If the heat exceeds a particular limit, the microcontroller sends signal to a buzzer through driver unit. Thus the user can identify the status of the motor and can switch off the motor. The microcontroller automatically switches off the motor through driver and relay. Since microcontroller is used, the operations are very sensitive. The microcontroller used is PIC 16F73. The microcontroller program is written in assembly language.
