Electrical – Poles of induction motor rotor

induction motormotormotor controllerpower electronicsthree phase

For a three phase squirrel cage induction motor (IM,) we can have 2 or 4 or 6 etc. pole pairs on its stator and when these stator windings are energized by 3 phase mains supply then we get a rotating flux inside the motor.

Can we say the same for the rotor of a squirrel cage IM also?

Please correct me if I am wrong that the rotor of an IM always has 2 poles regardless of the poles on its stator.

Best Answer

Induction motors have an even number of poles or any number of pole pairs formed on the stator by the winding pattern. The stator field induces currents in the rotor that form a matching number of poles on the rotor.
