COMMUTATOR

A commutator has an electrically non-conductive base and a plurality of commutator segments fixed to the base. Each segment comprises an electrically conductive connector and a segment part, wherein the connector has a segment portion, a terminal portion and anchors all formed as a monolithic construction. The terminal and anchors extend from the segment portion at radial ends thereof. The anchors fix the connectors to the base by being embedded therein. The segment part is a part of an annular disc forming an electrically conductive brush-contacting layer fixed to a side of the segment portion remote from the base. The segment portions are circumferentially separated by slits into which the base extends and the segment parts are separated circumferentially by slots. The slots are aligned with the slits, are narrower than the slits and extend axially into the material of the base within the slits between adjacent connectors.
