Why synchronous machine is called doubly excited machine?

Why synchronous machine is called doubly excited machine?

Last answer: Armature windings of synchronous machines either deliver 3 phase AC or absorb 3 phase AC source, whereas field windings are energized from DC source. Thus due to presence of AC on armature and DC on field windings, synchronous machines are often referred as doubly excited machines.
