Abstract
An electromagnetic transmission has three cylindrical structures concentric about a common longitudinal axis, the inner structure being a rotatably mounted primary armature having an input shaft extending along the axis and connected to a prime mover capable of rotating the primary armature, the outer structure being a stationarily mounted secondary armature, and the intermediate structure being a rotatably mounted field member having an even number of pole shoes whose surface-to-surface spacing from the primary and secondary armatures define the primary and secondary air gaps of the electromagnetic transmission, the field member having an output shaft extending along the axis for connection to a mechanical load.
