Low-Cost Wireless Speed Control and Fault Mitigation of Three-Phase Induction Motor
This chapter presents a design proposal for low-cost speed control and electrical fault mitigation of three-phase induction motors. The proposed system can control and monitor TIMs (three-phase induction motors) from far-flung areas. Here authors have proposed a relay-free system for fast fault clearance. IoT technology and low-cost microcontrollers have helped in achieving a system that is more reliable, economical, user friendly, and fast. It can be controlled by mobile application at the comfort of home. Data related to fault occurrence can be stored and analyzed for preventive maintenance. V/f scalar control method is used for speed control of TIM and able to control it in a wide range. Electrical faults such as over-current, over-temperature, over-voltage, and under-voltage are considered in this chapter. Simulation of the proposed design is done using Proteus 8 software. ESP32 is used to runs a web server that connects the mobile app with simulation.
