ABSTRACT:
A magnetic transmission having an input shaft and an output shaft with two or more gear assemblies, each gear assembly having an input sprocket affixed to the input shaft, an output armature with peripheral electromagnets affixed to the output shaft, a transfer drum concentric with the output armature and having electromagnets inset from the inside surface of the transfer drum and a drum sprocket on the periphery of the transfer drum, and a transfer chain engaging the input sprocket and the drum sprocket. A gear assembly actuator is used to select and energize a desired gear assembly. A hysteresis clutch can also be used in lieu of the output armature and the transfer drum.
