3-phase Induction Motor:Supply given to Rotor & Stator winding shorted

Click For Summary
SUMMARY

In a 3-phase slip ring induction motor, applying a balanced 3-phase supply to the rotor while short-circuiting the stator winding results in the rotor rotating against the direction of the rotating magnetic field. This phenomenon occurs due to the interaction between the rotor's magnetic field and the stator's magnetic field, even when the stator is not energized. The discussion clarifies the mechanics behind this operation, emphasizing the role of slip rings in supplying power to the rotor.

PREREQUISITES

In a 3 phase slip ring Induction motor, 3 phase balanced supply is given to rotor winding & stator winding is short circuited . Then rotor would - run against the direction of rotating field.

Can anyone explain this phenomenon?

Are you unable to understand why a motor housing would turn if you held the shaft and used slip rings to supply power to the motor housing?
