Actually 1) Armature winding have greater current than field winding.For large current in armature the greater amount of magnetic material required to produce linear magnetic curve. But rotor have lesser material than stator.
2) The heating loss on slip rings and brush contact will be increase if armature winging is om rotor.
Thank you.
