摘要： The invention relates to a multilayer brush (10), which substantially has a composite having a graphite component and having a copper component and a layered construction, wherein a first layer (11) is provided with a high copper component and a further layer (12) is provided with a comparatively low copper component. It is provided that the copper component of the first layer (11) in comparison to the copper component of the second layer (12) corresponds to a ratio of ≤ 3/2.

摘要： The invention relates to a carbon brush comprising a base body produced from a carbon material by pressing and optionally sintering, and a layer consisting of a metallic material and applied to an outer surface of the base body by pressing and optionally sintering. The metallic layer can be connected to the metallic carrier by welding or soldering.

摘要： The invention relates to a method of producing a flat commutator with a hub body formed from an insulating molded material, a plurality of conductor segments and a equal number of carbon segments that form the bearing surface. The hub body (9) is formed onto a conductor blank that is provided with radial grooves, said grooves being filled with the molded material. The composite (10) from the conductor blank and the hub body (9) is machined on the face of the conductor blank facing away from the hub body (9). A carbon ring (19) is glued onto the machined front face of the composite (10) and electrically conductive connections to the conductor blank or the conductor segments produced from the conductor blank are produced. The carbon ring (19) is then divided into carbon segments by cutting deeply into the molded material filling the grooves. The conductor blank is divided into the conductor segments either during machining of the front face by opening the radial grooves that are filled with the molded material or later on by separating cuts.
