The invention relates to the production of a planar commutator with a carbon running surface, wherein an annular closed corrugated conductor blank (1), comprising conductor segments (3) and bridging parts (4) connecting said bridging segments to each other, is produced by rolling from a longitudinal-stepped profiled strip section which is stamped on the edges thereof in order to create contact studs (7) and connection hooks (6). After the band section has been rolled, the contact studs (7) of the conductor segments are bent inwards in the direction of the axis (2) and are profiled on both axial front surfaces by means of a shearing process. The conductor blank is assembled with an annular carbon disk to form a composite part onto which a support element is molded by injection. The annular carbon disk is then subdivided into individual carbon segments and the bridging parts are removed or severed. ® KIPO & WIPO 2007 |
