Question

What are the 2 main categories of induction motors?

Answer 1

The two main categories of induction motors are:

1. Squirrel Cage Induction Motor:
   

   - This is the most common type of induction motor.
   - It has a rotor made of laminated iron cores, with conducting bars (usually aluminum or copper) embedded in it, forming a "cage-like" structure.
   - It’s simple, durable, and requires little maintenance.

1. Wound Rotor Induction Motor:
   

   - In this motor, the rotor has windings similar to the stator windings.
   - External resistors or controllers can be connected to the rotor windings to control speed or torque.
   - This type is used when high starting torque is needed or for adjustable-speed applications.

Both types work on the principle of electromagnetic induction, but the rotor construction and performance characteristics differ.
