Method for producing a flat commutator and a commutator produced according to this method

摘要

A method for producing a flat commutator includes forming a metallic supporting body with segment supporting parts and forming a hub of an electrically insulating material. The supporting body is connected in an electrically conductive and mechanically fixed manner to an annular disc resistant in a reaction-promoting environment. The supporting body is divided into segment support parts. The annular disc is divided into annular segments. The surfaces of the metallic segment supporting parts which are bare as a result of the division of the supporting body are coated with a coating that is resistant to the environment. The coating is carried out by currentless deposition. The commutator produced according to this method has the hub adjacent to the supporting body in the vicinity of the division.
