Classification: CPC H  F | IPC H

Claim 16:
17. 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; and
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 including an axial portion extending in an axial direction;
electrical machine bearings radially extending from the axial portion of 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 axial portion of the bearing support frame to the electrical machine shaft; and
a rotor assembly comprising:
a rotor support structure connected to the electrical machine shaft; and

a rotor attached to the rotor support structure such that the rotor is disposed radially inward of the stator and the rotor support structure is disposed radially between the electrical machine shaft and the rotor, wherein the rotor support structure extends in a radial and an axial direction from the end of the electrical machine shaft to mechanically alter a natural vibration mode of the electrical machine shaft,
wherein at least one of:
the rotor rotates in conjunction with the shaft of the propulsion engine via the intermediate shaft member to generate a power signal, and
the electrical machine receives power from an external source to provide rotational energy to the shaft.
