Question

What will happen if ac power supply is given to the rotor of an alternator?

Answer 1

What would happen if a rotor of an alternator was supplied withAC supply? If you remember principle of operation of a single phase induction motor,it states that a single phase excitation produces a time varying stationary field which can be seen as a forward rotating and backward rotating field at synchronous speed.

Answer 2

we give DC supply to field winding constant field is developed and we make the rotor rotate so that flux will be rotated and it cuts the conductors in stator and emf is induced in the armature winding.
