Dual-rotor, single input/output starter-generator
First Claim
Patent Images
1. A dual-rotor, single input/output starter-generator, comprising:
- a housing assembly;
a first motor/generator disposed within the housing assembly, the first motor/generator including at least a first main rotor shaft rotationally mounted within the housing assembly;
a second motor/generator disposed within the housing assembly, the second motor/generator including at least a second main rotor shaft rotationally mounted within the housing assembly;
a first main rotor shaft gear coupled to the first main rotor shaft;
a second main rotor shaft gear coupled to the second main rotor shaft; and
an input/output gear rotationally mounted on the housing assembly and in engagement with the first and second main rotor shaft gears, whereby the input/output gear receives a drive force from, or supplies a drive force to, one or both of the first and second main rotor shaft gears.

Abstract
A starter-generator includes redundant motor/generator sets disposed within a common housing. Each motor/generator set is electrically and mechanically independent of one another, with the exception of a common input/output gear. The starter-generator is configured such that if one of the motor/generator sets experiences a predetermined torsional load, it will decouple from the input/output gear, allowing the other motor/generator set to continue operation uninterrupted.

11. A dual-rotor, single drive shaft starter-generator, comprising:
-
a housing assembly;
a first main rotor shaft rotationally mounted within the housing assembly;
a first main rotor mounted on the first main rotor shaft;
a first main stator surrounding at least a portion of the first main rotor;
a first main rotor shaft gear coupled to the first main rotor shaft;
a second main rotor shaft rotationally mounted within the housing assembly;
a second main rotor mounted on the second main rotor shaft;
a second main stator surrounding at least a portion of the second main rotor;
a second main rotor shaft gear coupled to the second main rotor shaft; and
an input/output gear rotationally mounted on the housing assembly and in engagement with the first and second main rotor shaft gears, whereby the input/output gear receives a drive force from, or supplies a drive force to, one or both of the first and second main rotor shaft gears. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A dual-rotor, single drive shaft starter-generator, comprising:
-
a housing assembly;
a first motor/generator disposed within the housing assembly, the first motor/generator including at least a first main rotor shaft rotationally mounted within the housing assembly;
a second motor/generator disposed within the housing assembly, the second motor/generator including at least a second main rotor shaft rotationally mounted within the housing assembly;
a first main rotor shaft gear coupled to the first main rotor shaft;
a second main rotor shaft gear coupled to the second main rotor shaft; and
an input/output gear rotationally mounted on the housing assembly and in engagement with the first and second main rotor shaft gears, whereby the input/output gear selectively receives a drive force from, or supplies a drive force to, one or both of the first and second main rotor shaft gears, wherein the first and second motor/generators are each configured to selectively and independently prevent supply of the drive force to, or receipt of the drive force from, the input/output gear. - View Dependent Claims (20, 21)
