Abstract
A method of manufacturing a commutator. A connector plate is formed with a plurality of connectors arranged circumferentially about a central opening and interconnected by links, with each connector having a terminal portion, a segment portion and a number of anchors, with adjacent segment portions being separated circumferentially by slits. A conductive layer is fixed onto a first face of the segment portions to form a brush contacting surface. The connectors are separated by severing the links. The base is fixed to a second face of the connectors. Then the conductive layer is separated 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.
