Abstract
Description
Es ist bekannt, Elektromotoren werden über Schleifkontakte (Kohlebürsten) mit elektrischem Strom versorgt. Da die Kohlebürsten schleifen, geht ein Teil der Bewegungsenergie des Motors an Reibung verloren. Das wiederum hat einen relativ hohen Verschleiß der Kohlebürsten zufolge.It is known that electric motors are made using sliding contacts (Carbon brushes) with electric current provided. Since the carbon brushes grind, a part works the kinetic energy of the motor lost in friction. This in turn has a relatively high wear on the According to carbon brushes.
Der im Patentanspruch angegebenen Erfindung liegt das Problem zugrunde, die Reibung und den Verschleiß der Kohlebürsten zu vermindern.The invention specified in the claim is The problem is based on friction and wear of the carbon brushes.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß anstelle Kohlebürsten Kugellager verwendet werden, die nicht schleifen sondern abrollen. Das wiederum führt zu einer Verminderung der Reibung. Dadurch ergibt sich eine längere Lebensdauer.The advantages achieved with the invention exist especially in that instead of carbon brushes Ball bearings are used that do not grind but roll off. That in turn leads to one Reduction of friction. This results in a longer lifetime.
