Answer Posted / pundlik wanwe
A pilot exciter is a small ACgenerator with permanent magnets mounted on the rotor shaft and a 3-phase winding on the stator. It produces the power for the field circuit of the exciter, which in turn controls the field circuit of the main machine.
By using an integral AC exciter the necessity for brushes within the generator has been eliminated. The AC output of the rotating exciter armature is fed directly into the 3 phase, full-wave, rectifier bridge located inside the rotor shaft, which uses high temperature silicon rectifiers. The DC output from the rectifier bridge is fed to the main ac generator rotating field.
