1. An electrical machine comprising:
a stator assembly coupled to an engine stator component of a propulsion engine, the stator assembly comprising:
a stator support structure fixedly attached to the engine stator component;
a stator disposed on a supporting surface of the stator support structure; and
an electrical machine shaft 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 extending from the propulsion engine, the bearing support frame defining a bearing support cavity in conjunction with the electrical machine shaft;
first and second electrical machine bearings radially extending from the bearing support frame to rotatably contact the electrical machine shaft;
a sealing member disposed axially aft of the electrical machine bearings, the sealing member extending from the bearing support frame to the electrical machine shaft;
a rotor support structure connected to the electrical machine shaft; and
a rotor attached to the rotor support structure, wherein the rotor rotates in conjunction with the electrical machine shaft to exchange energy with the shaft of the propulsion engine.
