METHOD FOR PRODUCING A FLAT COMMUTATOR, AND FLAT COMMUTATOR
First Claim
1. A method for producing a flat commutator for a dynamoelectric machine, which commutator comprises an insulating support body (1), a plurality of carbon segments (2) and a plurality of conductor segments (5) connected electrically conductively therewith, wherein the carbon segments define a substantially plane brush running surface (4) and the conductor segments each have a rotor-winding terminal (6), the method comprising:
- preparation of an annular carbon disk (14);
molding of the support body (1) onto the annular carbon disk by injection-molding plastic material thereon in such a way that the support body bears interlockingly and frictionally thereon in radially outward position and radially inward position as well as on the end face (13) of the annular carbon disk opposite the brush running surface;
creation, in the support body, of openings (23) that extend from a surface (24) of the support body opposite the brush running surface to a surface (19) of the carbon segments (2) or of the annular carbon disk (14) opposite the brush running surface;
mounting of the conductor segments (5) on the support body in such a way that a contact pin (26) of the conductor segments passes respectively through one of the openings and at its free end contacts the surface (19) of the carbon segments (2) or of the annular carbon disk (14) opposite the brush running surface; and
separation of the annular carbon disk (14) into carbon segments (2) insulated from one another.

Abstract
A flat commutator having a support body, carbon segments, and conductor segments, wherein the support body is formed on the carbon ring disk, which is later separated into carbon segments that are insulated from one another, the support body sitting against the carbon ring disk radially outward, radially inward, and against the end face of the carbon ring disk, said end face lying opposite the brush contact surface. The conductor segments are subsequently applied individually such that a contact pin of each segment penetrates a cavity that extends from the support body surface lying opposite the brush contact surface to the surface of the segments or of the carbon ring disks, said surface lying opposite the brush contact surface; and the free end of said contact pin contacts the surface of the segments or of the carbon ring disk, said surface lying opposite the brush contact surface.
