    摘要: A high frequency starter-generator system uses an electric machine design that does not employ rotating rectifiers installed on the rotor. The output frequency of such a starter-generator is increased by about 200% as compared with a conventional starter-generator with the same number of poles operating in the same speed range. This design allows significant weight and volume reductions of the electric machine while its reliability is increased. The present invention may find application in any starter-generator application, including more electric architecture-type aircraft designs currently in development.

    摘要: When driven by a variable speed prime mover, a generator system provides relatively constant frequency AC power by independently controlling the main rotor flux rotational speed. The generator system includes an exciter stator that induces current in the exciter rotor windings at a desired frequency and phasing. The exciter rotor windings are electrically connected to and located in a common core as the main rotor windings to provide two-phase excitation current to the main rotor windings. The exciter stator winding is also located in a common core as the main generator stator windings. Excitation is supplied to the exciter stator from an exciter controller, which controls the frequency and phasing of the exciter excitation, based on the rotational speed and rotor position of the generator, to maintain a constant output frequency. The exciter frequency control function of the exciter controller may be eliminated when the generator system is driven by a constant speed prime mover or when a narrow band variable frequency output is required.

    摘要: A rectifier hub and associated cooling method provide increased cooling efficiency for rotating rectifier diodes in a dry cavity generator. The rectifier hub has an inner and an outer circumferential surface and includes at least one pair of flow passages, and at least one flow channel. Each pair of flow passages extends between the hub inner and outer circumferential surfaces, and each flow channel is formed in the hub outer circumferential surface and couples the pair of flow passages in fluid communication with one another. This configuration allows a cooling medium to flow directly across the rectifier hub and cool the rectifier diodes mounted within drive cavities formed in the hub.

    摘要: A wedge cooling apparatus and method for cooling a rotating machine, such as a generator, disperses a spray of cooling fluid into the wedges of the generator via a pipe that runs along the length of each of the wedges. The pipe may include a plurality of spray delivery devices to spray cooling fluid from the pipe to the inside of the wedges. The spray cooling method results in a high heat transfer coefficient of about 2000-3000 W/m2C as opposed to conventional conduction cooling, which has a heat transfer coefficient of about 200-300 W/m2C. The apparatus and method of the present invention efficiently removes heat from high powered, high current density designed generators.

    摘要: An axial impact liner comprises a bearing liner having a shear member and a pocket. A spring and a supply of oil may be included within the pocket. In the event of an axial load, such as from a bearing or main rotor failure, the axial impact liner can shear in the axial direction and absorb the energy of the axial load by forcing the shear member into the oil filled pocket and against the spring. The pocket comprises a volume capable of accommodating the full axial distance that the rotor could move.

    摘要: An electrical power system may comprise a power source, an electrical load and an interconnection path between the power source and the electrical load. At least one power-source current transformer may be positioned at the power source. At least one remote current transformer may be positioned remotely from the power-source current transformer so that a portion of the interconnection path is between the power-source and the remote current transformer. A control circuit may be interposed between the power-source and remote current transformers and may be responsive to current imbalance between the power-source and remote current transformers to disconnect the power source from the electrical load in the event of such imbalance. The at least one power-source current transformer may comprise a secondary winding having first and second ends, and a resistor connected across the first and second ends. This resistor may provide a path for current transformer secondary current to flow in the event of an open circuit failure in the control circuit or the interconnection path between the current transformer and the control circuit. Consequently voltage across the current transformer secondary may be limited to a level that will not damage the secondary windings. The control circuit may detect the open circuit failure and act to isolate the power source from the load with the minimum of time delay. The current transformer is thereby protected from open circuit failures.

    摘要: A shear gear arrangement with gear teeth on the bearing liner positioned to engage complementary teeth on a shear gear main body. The bearing liner is static, while the shear gear main body mounts on the rotating drive shaft. If a failure occurs, the drive shaft displacement causes the shear gear main body gear teeth to engage the bearing liner teeth, instantaneously loading the shear section of the shaft with a sufficient torque load to shear the section as designed.

    摘要: Apparatus for preventing incorrect installation of machinery components together includes a tab, pin and pin-receiving hole. The tab on the seal plate protrudes angularly from its periphery and laterally beyond it so as to prevent incorrect installation of two seal plates together in a faulty sealing relationship with machinery components by their tabs making interfering contact with one another producing a visible gap between the two seal plates. The pin is mounted on and protrudes axially from a surface of one machinery component facing the seal plate and prevents incorrect installation of the machinery components together in a faulty sealing relationship without the seal plate between them by the pin contacting the surface of the other machinery component and producing a gap between the machinery components. The hole extends through the seal plate to receive the pin within it when one seal plate is correctly installed between the machinery components.
