Abstract:
1. A method of manufacturing a commutator which comprises an electrically non-conductive base supporting a plurality of commutator segments forming a planer brush contact surface, each segment having a connector and a segment part fixed to the connector, the method comprising the steps of: forming a connector plate having a plurality of connectors arranged circumferentially about a central opening and interconnected by links, each connector having a terminal portion, a segment portion and a number of anchors, adjacent segment portions being separated circumferentially by slits, the segment portions having a first face and a second face opposite the first face, fixing a conductive layer on the first face of the segment portions to form a brush contacting surface, severing the links to separate the connectors, fixing the base to the second face of the connectors, separating the conductive layer into circumferentially arranged segment parts by cutting radial slots through the conductive layer aligned with the slits, the width of the slots being narrower that the width of the slits to avoid cutting the connectors.
