Design and Implementation of an IoT-Based Induction Motor Protection and Control System Using Arduino and ESP32

Abstract

Induction motors are critical components in both industrial and domestic applications due to their reliability, efficiency, and low maintenance requirements. However, their susceptibility to failures caused by overvoltage, undervoltage, overcurrent, excessive vibration, and temperature extremes necessitates robust monitoring and protection systems. This project proposes an IoT-based induction motor protection and control system that leverages the capabilities of Arduino Nano and ESP32 microcontrollers, along with various sensors, to ensure safe and efficient motor operation. The system continuously monitors key motor parameters such as voltage, current, temperature, vibration, and RPM, and employs a relay to de-energize the motor under fault conditions. Additionally, the system integrates IoT technology, utilizing the ThingSpeak platform for remote monitoring, enabling users to access real-time data and historical logs from anywhere. The proposed system not only enhances motor reliability and lifespan but also reduces energy consumption and operational costs. The design, implementation, and validation of the system are presented, demonstrating its effectiveness in preventing motor failures and optimizing performance.
