Which exciter component rotates and provides AC voltage to the rectifier components?

Which exciter component rotates and provides AC voltage to the rectifier components?

• A. Exciter Armature
• B. Rotor
• C. Stator
• D. Exciter Field

Answer: (A)

The rotating winding that generates the alternating voltage is the exciter armature. As it spins, it cuts the magnetic field and induces three-phase AC, which is then fed to the rectifier assembly to be converted to DC for the main generator’s field. The exciter field provides the magnetic field and stays stationary, while the rectifiers sit in a stationary position to convert the AC to DC. So the part that actually supplies the AC to the rectifiers is the rotating exciter armature.
