Why excitation is required?If the voltage not developed in
field,because of poor resuidual voltage in stator.thats why
externely giving some dc less voltage to stator field for
improveing resudial voltage. Resuidal voltage means ,some
few flex has alwayes present in stator poles,that is a
Resuidal voltage.
