ABSTRACT:
A flat commutator is described with carbon segments, metal segment-supporting parts supporting these and a hub body of an electrically insulating moldable plastic compound, which supports the segment-supporting parts, a solder layer is provided lying between the two segments for the connection between the carbon segments and the segment-supporting parts. The side surfaces of directly adjacent carbon segment-supporting parts which are facing one another are covered completely by the moldable plastic compound of the hub body. The method for producing this commutator is also described wherein the segment-supporting parts are soldered together with an annular plate later forming the carbon segments before the hub body is fitted onto the segment-supporting parts. The intermediate spaces between the segment-supporting parts are filled with moldable plastic material. Not until after the fitting is the annular plate subdivided into the individual carbon segments.
