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.
