What is a 3-Phase Squirrel Cage Induction Motor?

These types of motors function through the electromagnetism principle. It has a rotor inside that is commonly known as a squirrel cage rotor. Hence, it is called a squirrel cage motor. The rotor found in the 3-phase squirrel cage induction motor has a cylindrical shape with steel lamination. An aluminum, copper, or any conductive metal is embedded in its surface.

The rotor’s bar can be adjusted to increase speed-torque characteristics. Because of their ease of adjustment, self-starting, and reliability, these motors are widely used by different industries.

Construction and Structure

Construction and Structure

We manufacture a 3-phase squirrel cage induction motor with different parts such as the following:

Stator. A stator is composed of a metal housing and 3-phase winding.

Rotor. It is a part of the motor that rotates to provide the necessary amount of electrical energy. These are composed of aluminum bars, shaft, core, etc.

Fan. It is attached to the rotor’s backside to ensure heat exchange and maintains temperature.

Aside from that, these motors are also constructed with bearings for motion and rotation.

Difference of Slip Ring and 3-Phase Squirrel Cage Induction Motor

Below is the comparison of the two types of induction motors.

  • 3-phase squirrel cage induction motors are low-cost that slip ring.
  • Slip ring motors have high maintenance compared to squirrel cages.
  • A squirrel induction motor has higher efficiency during operation, unlike a slip ring motor.
  • 3-phase squirrel cage motors have good heat regulation than slip rings.
