Patent ID: 7449807

Claim:
Magnetic transmission comprising: a) input shaft having an input central axis; b) output shaft having an output central axis; c) plurality of generally cylindrical output armatures affixed to the output shaft, the output armatures having a longitudinal armature axis, each armature axis being aligned with the output central axis, the output armatures being generally concentric with the output shaft, each output armature having an output armature periphery which is generally concentric with the output shaft, each output armature having a plurality of generally longitudinal magnetic insets, each magnetic inset being inset from the output armature periphery, each magnetic inset containing an output armature magnet affixed in the magnetic inset; d) plurality of transfer drums, each transfer drum having a drum axis, each transfer drum having one or more transfer drum support members rotatably attached to the output shaft by a respective transfer drum bearing, each transfer drum having an inside circumferential drum surface, the transfer drum support members aligning the drum axis with the output central axis and spacing the inside circumferential drum surface from the output armature periphery of a respective output armature by a desired armature clearance, each transfer drum having a plurality of generally longitudinal magnetic elements, each magnetic element being inset from the transfer drum inside circumferential drum surface, each magnetic element containing an output transfer magnet affixed in the magnetic element; e) plurality of transfer belts, one or more transfer belts for each transfer drum; f) input transfer belt engagement means for each transfer belt for engaging the transfer belt by the input shaft and transferring energy from the input shaft to the transfer belt; g) output transfer belt engagement means for each transfer belt for engaging a selected transfer drum by the transfer belt and transferring energy from the transfer belt to the selected transfer drum; and h) gear assembly actuation means for selecting a desired output armature and a corresponding transfer drum and activating magnetic engagement between the selected output armature and the selected corresponding transfer drum.
