Patent number: 11901799Abstract: An electrical machine includes a stator assembly coupled to an engine stator component of a propulsion engine. The stator assembly includes a stator support assembly fixedly attached to the engine stator component and a stator disposed on a supporting surface of the stator support structure. The electrical machine also includes a rotor assembly including a rotor support structure connected to a shaft of the propulsion engine and a rotor attached to the rotor support structure such that the rotor is disposed radially inward of the stator. The rotor exchanges rotational energy with the shaft to operate as either an electrical motor or an electrical generator.Type: GrantFiled: February 8, 2021Date of Patent: February 13, 2024Assignees: General Electric Company, General Electric Company Polska sp. z o.o., General Electric Deutschland Holding GmbHInventors: Miroslaw Czarnik, Adam Tomasz Paziński, Bartłomiej Drozd, Darek Zatorski, Maciej Krzysztof Grunwald, Mohamed Osama, John R.

Publication number: 20230139068Abstract: An electrical machine includes a stator assembly coupled to an engine stator component of a propulsion engine. The stator assembly includes a stator support assembly fixedly attached to the engine stator component and a stator disposed on the stator support structure. An electrical machine shaft is coupled to an end of a shaft of the propulsion engine via an intermediate shaft member extending axially between the end of the shaft and the electrical machine shaft. A bearing support frame extends from the propulsion engine, the bearing support frame defining a bearing cavity in conjunction with the electrical machine shaft. Electrical machine bearings radially extend from the bearing support frame to rotatably contact the electrical machine shaft. A rotor attached to a rotor support structure attached to the electrical machine shaft. The rotor rotates in conjunction with the electrical machine shaft to exchange energy with the shaft of the propulsion engine.Type: ApplicationFiled: December 27, 2022Publication date: May 4, 2023Applicants: General Electric Company, General Electric Company Polska sp. z o.o., General Electric Deutschland Holding GmbHInventors: Miroslaw Czarnik, Adam Tomasz Pazinski, Bartlomiej Drozd, Darek Zatorski, Maciej Krzysztof Grunwald, Mohamed Osama, John R.

Patent number: 11492924Abstract: In one exemplary embodiment, a gas turbine engine is provided. The gas turbine engine defines a radial direction, an axial direction, and an axis extending along the axial direction of the gas. The gas turbine engine includes: a shaft configured to rotate about the axis; an electric machine comprising a rotor coupled to and rotatable with the shaft and a stator, the rotor defining an end along the axial direction; and a cooling manifold rotatable with the rotor and positioned at the end of the rotor, the cooling manifold configured to receive a flow of cooling fluid and provide the cooling fluid to the stator during operation of the gas turbine engine.Type: GrantFiled: July 21, 2021Date of Patent: November 8, 2022Assignees: GENERAL ELECTRIC COMPANY POLSKA SP. Z O.O, GENERAL ELECTRIC COMPANYInventors: Miroslaw Czarnik, Adam Tomasz Pazinski, Pawel Zdrojewski, Christopher N. Delametter, Lukasz Maciej Janczak, Maciej Krzysztof Grunwald, Scott Alan Schimmels
