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.
