ABSTRACT:
An AC synchronized generator includes an exciter stage and a generating stage, the exciter stage comprising an exciter stator connected for excitation to any conventional AC source and an exciter rotor driven in rotation therein by any convenient source of rotary power. The exciter rotor is mounted for common rotation with a generator rotor, the windings of the exciter rotor being connected in subtraction, or in an inverted connection with those of the generator rotor. A generator stator is then used to produce the current to a load. In this form the rotating magnetic field of the exciter stator will be added to the angular rate of the exciter rotor, which is therefor induced at an AC rate corresponding to the sum of these two angular rates. The generator rotor, being electrically connected in opposite direction but driven along with the exciter rotor, will carry a magnetic field which travels as the difference between the magnetic field in the exciter rotor and the rotor angular rate. The net difference that will appear at the generator stator will be equal to the rate of the AC source. Thus the load will see a generated current at the frequency of the AC source.
