Abstract
In one an exemplary aspect of the present disclosure, an engine includes a drive shaft; an electric machine including a stator assembly and a rotor assembly, the rotor assembly rotatable relative to the stator assembly; and an electrical break, the drive shaft coupled to the rotor assembly through the electrical break.
Claims19
An engine defining an axial direction, the engine comprising:
- a drive shaft;
- an electric machine comprising a stator assembly and a rotor assembly, the rotor assembly rotatable relative to the stator assembly, the rotor assembly comprising a rotor shaft;
- and
- an electrical break, the drive shaft coupled to the rotor shaft of the rotor assembly through the electrical break, wherein the drive shaft and the rotor shaft overlap along the axial direction, and wherein electrical break is positioned at least partially between the drive shaft and the rotor shaft.
1 more element
A method for operating an engine defining an axial direction, the method comprising:
- rotating a rotor assembly of an electric machine relative to a stator assembly of the electric machine with a drive shaft of the engine by transferring substantially all of a thrust between the rotor assembly and the drive through an electrical break;
- wherein the drive shaft is coupled to a rotor shaft of the rotor assembly through the electrical break, wherein the drive shaft and the rotor shaft overlap along the axial direction, and wherein electrical break is positioned at least partially between the drive shaft and the rotor shaft.
