construction of phase synchronous machine

Introduction of Construction of synchronous machines Like other rotating machines an alternator comprises of two main parts namely the stator and the rotor The stator is the fixed stationary part of the alternator Alternator carries the armature winding in which the voltage is induced The output of the alternator is taken from the stator
