Speed Control of Three Phase Induction Motor using Arduino

This project is proposed to control the speed of the three-phase induction motor by using the Arduino. 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 have two switches are used to increment and decrement the speed of the Three Phase Induction Motor. The speed variation can be viewed in the tachometer.

Description

ABSTRACT

This project is proposed to control the speed of the three-phase induction motor by using the Arduino controller. The Arduino controller is used to produce the pulse width modulation (PWM) signals. 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 have two switches are used to increment and decrement the speed of the Three Phase Induction Motor. The speed variation can be viewed in the tachometer.

DETAILS FOR 3 PHASE INVERTER BOARD

The inverter card comes with an inbuilt full bridge rectifier and filter capacitor. 6 No’s of IRFP250 MOSFETs are mounted with a Heat sink. The output of the inverter is terminated with 3 pin PTB Connector. The user should get soldered on the backside of the board for the gate pulse interface.

➣6 No’s of IRFP250 MOSFET are mounted with proper Heat sink

➣5A Bridge Rectifier with DC Filter Capacitor (1000uF/250V)

3 Pin PTB Connector provided to connect Three Phase Induction Motor
