摘要： An electromagnetically variable transmission includes an outer rotor (14) and an inner rotor (12). The inner rotor (12) is independently rotatable within a center aperture of the outer rotor (14). The outer rotor (14) is independently rotatable about the inner rotor (12). One of the rotors has a plurality of permanent magnets configured in pairs (18) and facing an air gap (30) disposed between the outer rotor (14) and the inner rotor (12). The other rotor has a plurality of slots (32) spaced about a magnetically permeable core having embedded windings (38). The outer (14) inner (12) rotors are simultaneously rotatable in one direction. In response to rotation of the outer rotor portion (14) and the inner rotor portion (12), a magnetic flux path is generated between the permanent magnet pairs (18), the air gap, the outer rotor core (14) and the inner rotor (12) portion core, to induce electrical power in the windings (38), which transfers power between the inner rotor portion (12) and the outer rotor portion (14).

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.

摘要： A system for generating supplemental electrical power from the low-pressure (LP) turbine spool (30) of a turbofan engine (10) includes a high-speed, high magnetic pole count, generator (50), a gearbox (44), a controller (52) and a power converter (54). The LP turbine spool (30)is mechanically coupled to the generator (50) portion by the gearbox (44) for driving the generator portion (50). The controller portion (52) has a speed-sensing element for sensing the LP turbine speed. The controller portion (54) disables the power converter (54) when the generator (50) exceeds a predetermined speed, and enables the power converter (54) when the generator portion (50) is less or equal to the predetermined speed. The effective load on the generator (50) is reduced to approximately zero when the LP turbine spool (30) exceeds the predetermined speed, permitting the generator (50) to be electrically bound up to the predetermined speed and mechanically bound in excess of the predetermined speed.
