Generally the field winding is placed on rotor but it can
be placed on stator, without loss of generality however
such arrangement has limiataions.
Rotating armature type synchronous machines:
DC Field winding is placed on stator where as AC armature
winding is placed on rotor.The electrical input(in case of
motor)and output(in case of alternator)is supplied to or
taken from rotating armature respectively by means of
brush.The brush cann't be employed satisfactorly for large
ratings.So this arrangement is lmited for small rated
machines only.
Rotating field type synchronous machines:
DC Field winding is placed on rotor where as AC armature
winding is placed on stator.The electrical input(in case of
motor)and output(in case of alternator)is supplied to or
taken from stationary armature respectively.This
arrangement is suitable for large rating because it is
relatively easier to design insulation for stationary
armatrure as compared to rotating armature.
