Design and Implementation of Arduino Based Star Delta Starting, F/R Direction Control and Fault Protection of Three Phase Induction Motor

Abstract

Three-phase induction motors have varied usage in industrial applications. At 50 Hz the most common reduced voltage starter is Star Delta. The popular applied method to minimize the start current of an induction motor is star to delta conversion. This project is designed to remotely control the starting of the induction motor through the star to delta conversion via mobile message command. The project also enables controlling of the forward and reverses motor direction along with phase fail and overload relay trip monitoring through the mobile communication system. The vital components of this project include a Two-channel relay board, a Magnetic Contactor, an Overload Relay, a Phase fail Relay, Timer Relay, Arduino Uno, and GSM SIM900A. The GSM module connected to the microcontroller sends a start command to the motor and after the system is ready the star to delta conversion happens after a certain time by an automatic timer relay. The user receives the current status of the motor and a call if any fault occurs during operation. This design of remotely Arduino controlled star delta starter, forward/ reverse motor movement, overload, and phase failure protection is safer to be used in factories and industries where the number of induction motors is widely popular.
