High-speed, high-power rotary electrodynamic machine with dual rotors
First Claim
1. A rotary dynamoelectric machine comprising:
- a stator having a plurality of windings;
a first rotor mounted on a first rotor shaft having first and second ends, the first rotor being mounted within the stator for rotation about a first rotor shaft axis, the first rotor having a magnetic device formed integral therewith and being disposed in proximity to one of the plurality of stator windings, and a second rotor mounted on a second rotor shaft having junction and pivot ends, the second rotor shaft being connected to the first rotor shaft at the junction end, the second rotor having a magnetic device formed integral therewith and being disposed in proximity to a second one of the plurality of stator windings.

Abstract
A high-power electrodynamic machine operates at a relatively high rotational speed and has dual rotors. In a preferred generator embodiment, one relatively massive first rotor having a magnetic device integral therewith is dedicated to the main generator. The exciter generator, which is relatively less massive, is isolated on a second rotor, which has a magnetic device integral to it. Only three bearings are required. The distance between the two bearings for the first rotor is relatively short, and the first rotor is relatively stiff, both of which facilitate operation of the first rotor below the critical speed. The junction of the first and second rotors further includes support of a junction end of the second rotor. The second rotor is driven by a prime mover via the first rotor. Means for providing electrical connections between the magnetic devices of the first and second rotors is also provided.
