Patent number: 11719122Abstract: A method of removing heat from an electrical machine located in a gas turbine engine at least partially inward of a core airflow path in a radial direction, the electrical machine comprising an outer electrical machine stator and an inner electrical machine rotor is provided. The method includes directing a liquid coolant radially inward past the outer electrical machine stator and toward an inner electrical machine rotor using a coolant passageway. The liquid coolant is directed onto and/or through one or both of the inner electrical machine rotor and a rotor support thereby removing heat from the inner electrical machine rotor.Type: GrantFiled: February 8, 2021Date of Patent: August 8, 2023Assignees: General Electric Company, General Electric Company Polska sp. z.o.o., General Electric Deutschland Holding GmbHInventors: Adam Tomasz PaziĆski, Tomasz Jan Bulsiewicz, Bartlomiej Drozd, Miroslaw Czarnik, 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.
