A three phase induction motor is sometimes calles a generalized transformer in so far as voltage and frequency transformation has been concerned. How a three phase induction motor operates when rotor frequency is equal to stator frequency?
A)it will not operate
B)it will operate as induction motor only
C)it will operate as induction generator
D)it will operate in braking mode

When the rotor frequency is equal to the stator frequency in a three-phase induction motor, it means the rotor is not moving relative to the magnetic field produced by the stator. This condition implies that the motor will not operate because induction motors rely on the relative motion between the rotor and the stator's magnetic field to induce current in the rotor, which in turn creates the magnetic field necessary for the rotor to turn.
