Abstract

Die Erfindung betrifft eine Kohlebürste (1) für eine elektrische Maschine, die einen Kollektor (2) federnd beaufschlagt, wobei die Kohlebürste (1) in einer Führung (3) radial zu dem Kollektor (2) bewegbar angeordnet und mit einem Biegeschenkel (7) biegesteif verbunden ist. Die Kohlebürste läßt sich einfach und kostengünstig in einen Motor einbauen und elektrisch kontaktieren. Der Biegeschenkel (7) dient einerseits der federnden Zustellung der Kohlebürste (1) zu dem Kollektor (2) und andererseits der elektrischen Stromversorgung.

Figure 00000001
The invention relates to a carbon brush (1) for an electrical machine, which resiliently acts on a collector (2), the carbon brush (1) being arranged so as to be movable in a guide (3) radially to the collector (2) and having a bending leg (7) is rigidly connected. The carbon brush can be easily and inexpensively installed in a motor and electrically contacted. The bending leg (7) serves on the one hand for the resilient delivery of the carbon brush (1) to the collector (2) and on the other hand for the electrical power supply.
