Flat commutator for e.g. electrical machine, has bar widened in circumferential direction when axially viewed from brush running surface in direction of connection hook and/or viewed from connection hook in direction of running surface

摘要

The commutator (1) has contact segments (4) fixed and connected with a radial section of a metallic segment carrier part (6) in an electrically conductive manner. A hub body is made of an electrically insulating material to carry the segment carrier part. A bar (9) is widened in a circumferential direction when axially viewed from a brush running surface (5) in a direction of a winding connection hook (8) and/or viewed from the winding connection hook in a direction of the brush running surface.
