US 12,637,995 B2 · Integrated gear motor (IGM)

Abstract

An example machine-gear system that connects to a prime mover in which the prime mover may operate at a first rotational speed and the machine may operate at a different rotational speed. The gear system, of the machine-gear system, may be configured to connect the prime mover and the machine such that the prime mover operates at the first rotational speed and the machine may operate at the different speed. The gear system may be located within the housing of the machine, which may result in a more compact machine-gear system, than for other arrangements. In some examples, the gear system may include two or more stages. In some examples, the multiple stage gear systems may be configured to engage or disengage from one, or more, stages, which may result in a machine-gear system that operates at two or more different rotational speeds as the operational modes change.

Dependent claims

A method comprising:

selectively engaging a first stage to a second stage of an integrated gear machine during a starting mode, wherein:
the integrated gear machine comprises a multi-stage epicyclic gear assembly and an electric machine,
the multi-stage epicyclic gear assembly comprises the first stage and the second stage,
the electric machine comprises a drum rotor, wherein the drum rotor is rotationally coupled to a prime mover;
the epicyclic gear assembly is located at least partially within an open interior space of a drum rotor for the electric machine, and
a ring gear for the epicyclic gear assembly is attached to the drum rotor;
selectively disengaging the first stage from the second stage during a generating mode;
and
operating the electric machine in either a first operating mode or the generating mode.
