Q.If we put field winding on stator and armature winding on rotor then how will it operate? Will it rotate at synchronous speed or not? (Assuming that the alternator is feasible?
Ans:-
Yes, It would surely operate and run at synchronous speed. But it would be uneconomical because we should have 3 slip rings of very high current handling capacity and because of this efficiency will decrease and we will require to have high level of insulation ...
