AC MACHINE FUNDAMENTALS
1010603AC MACHINE FUNDAMENTALSAC machines are motors that convert ac electric energy to mechanical energy and generators that convert mechanical energy to ac electric energy. The two major classes of ac machines are synchronous and induction machines. The field current of synchronous machines (motors and generators) is supplied by a separate dc power source while the field current of induction machines is supplied by magnetic induction (transformer action) into the field windings.AC machines differ from dc machines by having their armature windings
