Abstract
An engine includes: a first rotating component; a second rotating component separate from the first rotating component; and an electric machine, the electric machine including a first rotor rotatable with the first rotating component; a second rotor rotatable with the second rotating component; and a stator assembly arranged between the first rotor and the second rotor, the stator assembly including a first set of windings arranged adjacent to the first rotor, a second set of windings arranged adjacent to the second rotor, and a non-ferromagnetic inner housing arranged between the first set of windings and the second set of windings.
Claims20
An engine comprising:
- a first rotating component;
- a second rotating component separate from the first rotating component;
- and
- an electric machine, the electric machine comprising
- a first rotor rotatable with the first rotating component;
- a second rotor rotatable with the second rotating component;
- a stator assembly arranged between the first rotor and the second rotor, the stator assembly comprising a first set of windings arranged adjacent to the first rotor, a second set of windings arranged adjacent to the second rotor, and a non-ferromagnetic inner housing arranged between the first set of windings and the second set of windings.
An electric machine for an engine, the electric machine comprising:
- a first rotor;
- a second rotor;
- and
- a stator assembly arranged between the first rotor and the second rotor, the stator assembly comprising a first set of windings arranged adjacent to the first rotor, a second set of windings arranged adjacent to the second rotor, and a non-ferromagnetic inner housing arranged between the first set of windings and the second set of windings.
A method of operating an electric machine for an engine, the electric machine comprising a first rotor rotatable with a first rotating component of the engine, a second rotor rotatable with a second rotating component of the engine, and a stator assembly arranged between the first rotor and the second rotor, the method comprising:
- operating a first set of windings of the stator assembly with the first rotor as a first electric motor or a first electric generator;
- and
- operating a second set of windings of the stator assembly with the second rotor as a second electric motor or a second electric generator independently of operating the first set of windings of the stator assembly with the first rotor as the first electric motor or the first electric generator.
