Claim 15:
16. A method for operating a generator coupled to an engine including:
rotating an exciter armature device relative to an exciter field device to generate a rotating exciter magnetic field in a first air gap;
imparting a first voltage at a first set of coils via the rotating exciter magnetic field and the first air gap;
rotating a rotor field device including a second set of coils;
generating a main magnetic field that imparts a second voltage on a main stator device via a second air gap; and
outputting a generator voltage of the generator in response to the main magnetic field as a function of at least a rotating speed of the rotating exciter magnetic field,
wherein the generator voltage of the generator is independent of a speed of the engine,
wherein the main stator device and the exciter field device lie in on a common plane normal to an axis of rotation, and the exciter armature device is inwardly spaced from the exciter field device, main stator device, and the rotor field device, and
wherein the exciter armature device and the rotor field device are integrally formed with a flywheel of an engine.
