Answer Posted / neeraj insa
All m/c generating AC power supply in the universe except
battery.in the gen. we apply dc power on rotor which r
short ckt at ends(some times on stator also),that create a
magnetic field on rotor name north & south pole.as rotor
rotate than the magnetic field north pole cut by stator
conductor that produce +ve half cycle.as rotor move north
pole magnetic field cut by stator conductor,that create -ve
cycle.so in this whole process we get ac.The function of
the
commutator to convert ac into dc,becouse commutator is a
mech. rectifier.
