Description

IoT Based Three Phase Induction Motor Speed Monitoring and Control

This project is proposed to control and monitor the speed of the three-phase induction motor by using the Arduino and node MCU controller. The Arduino controller is used to produce the pulse width modulation (PWM) signals. IoT Based Three Phase Induction Motor Speed Monitoring and Control

And the motor speed is controlled by using the driver and three-phase inverter circuits. And also this project has reduced the harmonics and switching losses of the circuit. In this project Node, MCU is used to increment and decrement the speed of the induction motor. The speed feedback is connected to the Node MCU controller. The Node MCU transfer the speed signal through Wi-Fi. IoT Based Three Phase Induction Motor Speed Monitoring and Control
