Design of Three-phase Induction Motor

4.1 Introduction

Three-phase induction motor is an important class of electric motor, which finds its application in various industrial and agricultural sectors. More than 80% of industrial motors are induction motors.

A three-phase induction motor essentially consists of two parts, namely the stator and the rotor. The fixed stator core carries three-phase balanced stator winding placed in the stator slots. Two different types of rotors are usually used in induction motors. They are as follows:

  1. Cage rotor that resembles the cage of a squirrel usually referred as squirrel cage rotor and
