ELECTRICAL MACHINES FOR INTEGRATION INTO A PROPULSION ENGINE

An electrical machine includes a stator assembly (302) coupled to an engine stator component of a propulsion engine (100). The stator assembly includes a stator support assembly (308) fixedly attached to the engine stator component and a stator (314) disposed on the stator support structure. An electrical machine shaft (502) 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 (514) extends from the propulsion engine, the bearing support frame defining a bearing cavity (520) in conjunction with the electrical machine shaft. Electrical machine bearings (522, 524) radially extend from the bearing support frame to rotatably contact the electrical machine shaft. A rotor (346) is 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.
