The squirrel cage induction motor uses a magnetic field to drive a rotor. Its induced voltage is one to three percent higher than the synchronous speed of a magnetic field. This difference in speed is called "motor slip." A squirrel cage induction motor is not a loss-free motor, and the current it produces is not loss-free.

The construction of squirrel cage induction simple and rugged. Construction of slip ring induction motors needs slip rings, brushes, short-circuiting device, etc. This type of motor has less overhang and better space factor in slots. These motors have the highest overhang and poor space factor in slots. Cost and maintenance are less.

In a double-cage induction motor, it is assumed that the two cages develop two separate torques. Thus, the total torque developed in the double-cage induction motor is equal to the sum of the two cage torques. The torque-slip characteristics of the two cages and the total torque of the motor is shown in the figure.
