Abstract (en)
[origin: US2007294877A1] 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.
