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?

It will operate as induction motor only

It will operate as induction generator

It will operate in braking mode
