    摘要: A rotating electric machine is provided which includes multiple independent control windings for compensating for rotor imbalances and for levitating/centering the rotor. The multiple independent control windings are placed at different axial locations along the rotor to oppose forces created by imbalances at different axial locations along the rotor. The multiple control windings can also be used to levitate/center the rotor with a relatively small magnetic field per unit area since the rotor and/or the main power winding provides the bias field.

    摘要: A gas turbine engine assembly includes an electromagnetic machine for extracting power from the turbine engine. The electromagnetic machine includes an outer rotor and an inner rotor rotatably supported adjacent to a stator disposed between the inner and outer rotors. The stator has an inner set of windings disposed on an inner surface adjacent to the inner rotor, and an outer set of windings on an outer surface of the stator adjacent to the outer rotor. The inner stator windings form a set of multiple-phase windings, and the outer stator windings form a set of multiple-phase windings.

    摘要: A system for transferring torque between a pair of independently, concurrently rotating shafts of a turbofan engine includes a magnetic gearbox. The magnetic gearbox has a first ring structure, a second ring structure and an intermediate ring structure. Each ring structure has an annular aperture therethrough and a plurality of permanent magnets embedded therein. The intermediate ring structure is disposed between the first and the second ring structures. Each ring structure is coaxially concentric with, and independently rotatable with respect to the remaining ring structures. The first and second ring structures are each coupled to separate ones of the rotating engine shafts, and the intermediate ring is operable to transfer torque between the pair of shafts. Preferably, the intermediate ring structure is coupled to a rotating machine. The rotating machine has a controller, and is operable for adjusting a ratio of torque transferred between the pair of shafts.

    摘要: In a dynamoelectric generator, a low-resistance electrical contact is provided by a multilam or belleville spring mounted between the outer surface of the rotor body and an overlapping retaining ring. This contact forms a conductive current path for high-frequency eddy currents induced on the surface of the rotor and retaining rings at all operating speeds.
