    The rotor’s magnetic field interacts with the stator’s rotating magnetic field, creating a torque that causes the rotor to rotate. The direction of the torque depends on the relative direction of the magnetic fields. In a three-phase induction motor, the rotor always tries to follow the rotating magnetic field of the stator. Step 4: Rotor Slip.
