Abstract:
1. A starter-generator system comprising: a main generator having a main generator rotor and a main generator stator, the main generator rotor including two phase main rotor windings wound thereon; an exciter having an exciter rotor and an exciter stator, the exciter rotor having two phase exciter rotor windings wound thereon; wherein the two phase exciter rotor windings are configured to provide AC excitation current to the two phase main rotor windings without passing through a rectifier; and wherein a lack of rectifier diodes on the generator rotor results in a frequency addition at a generator output; and wherein the main generator produces power having a frequency higher than a generator that contains rectifier diodes and the main generator has the same number of poles as the generator that contains rectifier diodes.
