摘要:
A system for transferring torque between a pair of independently, concurrently rotating shafts of a turbofan engine includes a magnetic gearbox. The magnetic gearbox has a first ring structure (116), a second ring structure (112) and an intermediate ring structure (114). Each ring structure has an annular aperture therethrough and a plurality of permanent magnets embedded therein. The intermediate ring structure (114) is disposed between the first (116) and the second ring structures (112). Each ring structure is coaxially concentric with, and independently rotatable with respect to the remaining ring structures. The first (116) and second ring (112) structures are each coupled to separate ones of the rotating engine shafts, and the intermediate ring (114) is operable to transfer torque between the pair of shafts. Preferably, the intermediate ring structure (114) is coupled to a rotating machine. The rotating machine has a controller, and is operable for adjusting a ratio of torque transferred between the pair of shafts.

The present invention provides an electric actuator motor (5) for controlling multiple linkages. The invention comprises a housing, a plurality of stator portions (14,15,16) within the housing wherein each of the stator portions (14,15,16) comprises laminated magnetic sections includes a plurality of stator poles. The invention further comprises a plurality of rotors (11,12) movable between the stator portions (14,15,16) wherein each rotor includes a plurality of rotor poles (21) comprising magnetic laminated portions positionable between nonmagnetic spacers (26) of the rotor. Electromagnetic means for moving the rotors (11,12) between the stator portions (14,15,16) are also included. The invention further comprises bearings (5') for guiding the rotors (11,12) as they traverse between the stator portions (14,15,16). The rotors (11,12) include posts (19,20) that are used for mounting the rotors (11,12) on a support ring (13).
摘要:
An electromagnetic machine that generates electric power from an engine by having rotor poles on the tips of the fan blade airfoils and stator elements circumferentially placed around the blade airfoils. As the pole tips on the blade airfoils are excited, they rotate past the stator elements, causing a magnetic flux change in the stator. The magnetic flux change results in an electric potential that is used to provide power.
