Abstract
Methods and systems are provided for integrating a gearbox into an electric motor. In one example, a system may include enclosing a gearbox containing a planetary gear set and a differential within an envelope of a rotor of the electric motor.
Claims18
A system for an electric motor, comprising:
- one or more of a planetary gear set and a differential integrated within an envelope of a rotor of the electric motor wherein the planetary gear set includes a first planet gear meshing with a first sun gear mechanically coupled to a housing of the electric motor, and wherein the first planet gear is coupled to a core of the rotor.
A system for an electric motor, comprising:
- each of a compound planetary gear set and a planetary differential gear set positioned within an envelope of a rotor of the electric motor, the compound planetary gear set and the planetary differential gear set aligned along a central axis of the envelope, wherein the compound planetary gear set comprises a first sun gear grounded to a housing of the electric motor, the housing enclosing the rotor of the electric motor.
A system for an electric motor, comprising:
- a first planetary gear set housed within an enclosure of a rotor;
- a second planetary gear set housed within the enclosure of the rotor;
- and
- a differential gear set housed within the enclosure of the rotor, the first planetary gear set positioned on a side of the differential gear set along a central axis and the second planetary gear set positioned on another side of the differential gear set along the central axis;
- and
- a cooling system coupled to the enclosure of the rotor, the cooling system including a plurality of passages coupling a heat exchanger and a pump to each of the differential gear set, the first planetary gear set, and the second planetary gear set.
