Different Types of Rotors and their Characteristics

As a general rule, construction of an induction motor consists essentially of two main parts :

a) a stator and b) a rotor

In rotor construction, there are two types of motors are coming..

  • Squirrel cage rotor motor

  • Phase wound or wound rotor motor

Let’s know something about the construction:

  1. Squirrel cage rotor: 

Almost 90% of induction motors are squirrel cage type because this type rotor has the simplest and most rugged construction. The rotor consists of a cylindrical laminated core with parallel slots for carrying the rotor conductors.

2. Phase wound or wound rotor: 

This type rotor is provided 3 phase, double layer, distributed winding consist of the coil as used in alternators.
