Answer Posted / thuranga

I exactly does not know the right answer for it...but what I
think is ,in the alternator the AC voltage collected at
sliprings where it turns out to be ac becoz there will be
not breaks as on commutator(for DC gen/mot)

so as far as I know if the alternator consists the mica gaps
on the shaft or commutator then it acts DC gen....
but without those gaps even if we put the brushes also the
current collected at brushes will be ac only.but the only
problem is the maximum power will be wasted at the brushes.
(this is my view,tell me if it is wrong).thanking you
