Abstract
An electrically driven power system includes a carrier structure rotatably supporting a power output. A plurality of individually electrically powered primary drive units are also mounted in the carrier structure. Each of the power units are in driving engagement with the power output for driving said power output in a rotating manner. The electric motors driving the power units are interchangeable thus eliminating a single point motor failure and their smaller size facilitates ease of replacement and repair.
Claims28
An electrically driven power system for providing a rotational power output, said power system comprising:
- a carrier structure;
- a power output rotatably supported in said carrier structure;
- a plurality of individually electrically powered primary drive units mounted in said carrier structure, each said power unit in driving engagement with said power output for driving said power output in a rotating manner;
- and
- at least a first secondary drive unit mounted in said carrier structure, said first secondary drive unit being independently powered separate from said primary drive units and further wherein said first secondary drive unit is coupled in driving engagement with one of said primary drive units;
- a second secondary drive unit mounted in said carrier structure, said secondary drive unit being independently powered separate from others of said drive units and further wherein said second secondary drive unit is coupled in driving engagement with said first secondary drive unit.
An electrically driven power system for providing a rotational power output, said power system comprising:
- a carrier structure;
- a power output rotatably supported in said carrier structure;
- an electrically powered primary drive unit mounted in said carrier structure, said primary power unit in driving engagement with said power output for driving said power output in a rotating manner;
- and
- a plurality of individually electrically powered secondary drive units mounted in said carrier structure, each said secondary power unit in driving engagement with said primary drive unit for augmenting said primary drive.
An electrically driven power system for providing a rotational power output, said power system comprising:
- a first carrier plate;
- a second carrier plate affixed to said first carrier plate in a substantially parallel spaced apart manner defining a gear space therebetween;
- a sun gear rotatably supported in said gear space;
- at least one primary planet gear supported in said gear space in like manner and intermeshed with said sun gear;
- at least one secondary planet gear supported in said gear space in like manner and intermeshed with said primary planet gear;
- and
- an electric motor drivably coupled to each of said primary planet gear and said secondary planet gear for providing power to said power system.
