Abstract
The present invention is an improved electrical cylindrical circuit collector ring assembly. The assembly includes an axial stack of multiple torodial-shaped spacer members and at least one electrical conductor ring member. The spacer members each include one insulating face and one electrically conductive face. The ring assembly also includes a general adhesive for mounting the insulator face to the ring members and an electrically conductive adhesive for mounting the conductive face to the ring members and for mounting ring members to ring members where applicable. The ring assembly also includes a radial extension on each of the conductive faces of the spacer members beyond the ring member diameter providing for an electrical connecting point. Finally, radial tabs provide lead wire channels and means of improved electrical shielding.
