Answer Posted / rahul
alternators are called ac generators,they are synchronous generators that runs at synchronous speed, ac&dc generators works on same principle of electromagnetic induction.in case of dc generator armature rotates and field remains stationary, where as in alternator field rotates and armature winding(stator winding) remains stationary. in case of alternator the generated voltage are taken out from the stator winding where as in dc generator the induced ac voltage is first converted to dc by using a commutator and the output is taken from the rotating commutator by using brushes. in case of alternator better insulation can provided if generated voltage are taken from stationary winding and the dc supply to field winding is provided by using brushes.
