Abstract

Die Erfindung bezieht sich auf eine Kohlehalteranordnung bestimmt für Elektromotoren umfassend einen aus elektrisch isolierendem Material wie Keramik- oder Kunststoffmaterial bestehenden Träger (16) mit zumindest einem von diesem ausgehenden aus Metall bestehenden köcherformigen Kohlebürstenhalter (16). Um eine entsprechende Kohlehalteranordnung kostengünstig herstellen zu können und gleichzeitig sicherzustellen, dass eine in dem Kohlebürstenhalter axial verschiebbare Kohlebürste (14), wie Schichtkohlebürste hinreichend genau geführt wird, ohne dass Querströme fließen, wird vorgeschlagen, dass zumindest zwei gegenüberliegende Innenflächen (30, 32) des Kohlebürstenhalters aus elektrisch isolierendem Material bestehen oder dieses aufweisen oder jeweils mit einer aus elektrisch isolierendem Material bestehenden Abdeckung versehen sind.

Figure 00000001
The invention relates to a carbon holder arrangement intended for electric motors, comprising a support (16) made of electrically insulating material such as ceramic or plastic material with at least one tubular carbon brush holder (16) made of metal. In order to be able to produce a corresponding carbon holder arrangement inexpensively and at the same time to ensure that a carbon brush (14), such as a layered carbon brush, which is axially displaceable in the carbon brush holder, is guided with sufficient accuracy without cross currents flowing, it is proposed that at least two opposite inner surfaces (30, 32) of the Carbon brush holder consist of electrically insulating material or have this or are each provided with a cover consisting of electrically insulating material.
