| Abstract |
In a plane commutator with a support member, a plurality of conductor segments and an equally large number of carbon segntents connected interlockingly and electrically conductively to the conductor segments, each carbon segment is provided with an annular projection disposed opposing the brush running surface, the end face of the said projection being in contact with a corresponding annular contact face of the associated conductor segnaent. The annular contact faces are each surrounded by a contact ring of the conductor segment in question, which segment is in gap-free contact with the associated annular projection. On each conductor segment, there projects a contact pin, which engages without gaps in a corresponding bore of the associated annular projection of the carbon segement in question.Thus the carbon segments are each connected electrically conductively via the outer circumferential face, the annular end face and the inner circumferential face of the annular projection to the conductor segments. |
