Commutator, especially a flat commutator for an electrical machine

摘要

The invention relates to a commutator, in particular a flat commutator of an electrical machine, which includes a commutator body 12 made of plastic and a plane surface arranged transversely to the axis of rotation of the commutator and carrying a metal coating 14, preferably a copper coating, on which surface are formed commutator segments 20, to each of which is respectively connected a connecting conductor belonging to the machine. A particularly simple and stable connection of a carbon-containing segmented coating 20 on the plane surface of the carbon-containing segmented coating 20 on the plane surface of the metal coating 14 is achieved in that the carbon-containing coating is connected to the commutator body 12 by means 18 and/or 22 for holding in at least positive engagement. <IMAGE>
