Q. A three phase induction motor is sometimes called 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 greater than stator frequency? (Solved)
1. rotor will be driven against rmf
2. rotor will be driven in direction of rmf
3. no emf will be induced
4. the losses will be maximum
- a. rotor will be driven against rmf
