  • Patent number: 4146805
    Abstract: The drive uses a recessed wall or partition between the pole-rings of the two rotors to substantially diminish the occurrence and strength of eddy currents. The recesses may be in the form of grooves, depressions or axial bores which reduce the mass of the wall. The wall is further reinforced by non-magnetic electrically non-conductive or insulated elements of high tensile strength to compensate for the reduction in strength caused by the grooves, depressions or bores.
