Answer Posted / swapnil
if we use ac exitation it will creat alternatly changing
flux and pole will also be changing with flux in case of dc
it will produce constant flux and constant pole as rotor is
rotating sin wave will be genrated in genrator if ac will
be given for exitation sine wave distortion will take place.
