ABSTRACT:
An axial field flow-through rotor apparatus comprises a structure formed of magnetic strip wound around a hub in such a way that the first and last layers of strip have surfaces that form coaxial cylinders and edges that define the inner and outer perimeters of parallel washer-shaped faces. The distance between the washer-shaped faces corresponds to the width of the magnetic strip. A plurality of equally spaced radial slots are cut into one of these faces to a selected depth corresponding to a portion of the strip width. A spider that is formed of conductive material and has one spoke for each slot is then placed into the cut face. A plurality of equally spaced radial slots are then cut into the other face at locations that correspond to those at which slots were cut into the first face and to a depth that corresponds to the previously uncut strip width. Thereafter, a second spider, formed of a conductive material and having one spoke for each slot, is placed into said other face.
