Squirrel Cage Induction Motor
In Squirrel Cage Induction Motor, the rotor conductor are permanently shorted by the Aluminum /Copper ring called the end ring forming a complete closed circuit like squirrel cage , That's why it is known as Squirrel Cage Induction Motor
Construction:
Rotor:
The rotor is in cylindrical in shape. It consists of two rings which are permanently shorted with each others by parallel aluminum bars which are a slightly skewed to prevent the magnetic locking of the stator and the rotor teeth, makes the working of motor more smooth and quiet. Rotor resistance is very small and as the bars of the rotor is permanently shorted, no external resistance can be added.

Insulated iron core lamination are inserted in squirrel cage rotor to aid the current loss in the rotor bars.
