International Classification:

H02K 346

US Classification:

310270

Abstract:

A new improved system and method for end turn retention for wires on a generator rotor for use in high speed applications such as in aircraft applications. The rotor includes a shaft, spokes, supports, and wire winding coils, and at least one cap device. The spokes extend radially outwardly from the shaft, and each support is positioned on an associated spoke. Each coil wraps around an associated support and spoke. Each cap device is coupled to an end of its associated spoke to prevent the windings from moving radially outwardly while the rotor spins. Each support is coupled to an associated cap device, and includes at its radially inward edge a flange protruding away from the respective spoke. Because of the flange and the cap device, slack of the wire coil between the flange and the associated cap is taken up.

International Classification:

H02K 1101

US Classification:

310 61, 310 58, 310 52

Abstract:

An improved apparatus and method of having a pair of end caps on a rotor assembly of a multi-pole high-speed generator is provided for use with a turbine engine. The rotor assembly provides improved balancing and/or cooling during generator operation. The rotor assembly includes a plurality of poles and at least one support wedge positioned between each of the poles. The rotor assembly is mounted on a shaft. An annular flange of the end caps restrains the support wedges in the rotor assembly for improved balancing and maintaining concentricity. The end caps may also include a manifold for circulating a cooling medium through the shaft to and from the support wedges to cool the generator.

Honeywell International, Inc. - Morristown NJ

International Classification:

H02K 516

US Classification:

310 91, 310 90, 31015616

Abstract:

A high speed generator with a hydraulic rotor mounting system that dampens rotor vibrations at the rotors critical speeds. Oil is supplied to a gap formed between the outer race of the rotor bearing assembly and the bearing liner. The oil provides soft bearing support for, and viscous damping of, the rotor.

International Classification:

H02K 900

US Classification:

310 54, 310 58, 310 59, 310 60 A

Abstract:

A lubricating and cooling system for a high speed generator that directs a lubricating and cooling medium through the generator housing. The lubricating and cooling medium may be supplied to the generator on either end of the housing. A portion of the medium is supplied to the generator bearings. The remaining portion then flows through the rotor shaft, through the rotor, back to the shaft, where a portion may be sprayed onto the rectifier assemblies, then passed through the stator, and out of the generator.

Abstract:

A rotor with wedges and a method of retaining wedges in a rotor are disclosed. The rotor includes a shaft, first and second poles extending radially from the shaft, and first and second coils of windings respectively wrapped around the first and second poles. Each coil includes a respective outer face including two end portions and two side portions, and a respective inward-facing edge including two end sections and two side sections. The rotor further includes a first outer wedge positioned between neighboring side portions of the first and second coils, and a first inner wedge positioned between neighboring side sections of the first and second coils. The first inner wedge is coupled to the first outer wedge so that the first outer wedge is at least partly retained from moving radially outward away from the shaft.
