Title: Segmented induction electric machine with interdigitated disk-type rotor and stator construction

Abstract: The present invention relates to an A. C. electrical machine comprising: a plurality of disk-shaped annular stator elements stacked and spaced equidistantly from each other and mounted on a frame; a plurality of disk-shaped rotor elements mounted on a rotational axis and spaced equidistantly from each other such that successive rotor elements are positioned between successive stator elements; a plurality of electrical windings on each of the first stator elements, which when energized with a current flow, produce a magnetic field in a direction substantially parallel to the axis; and a return path for completing a magnetic flux path in a second direction perpendicular to the first direction on successive stator elements and through the rotor elements for generating a rotational force in the rotor elements.
