Kohlehalter für Kollektormotoren mit integrierter EntstördrosselCoal holder for collector motors with integrated Interference suppression choke

Der Erfindung lag die Aufgabe zugrunde, eine Entstördrossel räumlich möglichst nahe an den Störer (Kohle-Kollektor) heranzubringen und den Aufwand für die Herstellung und Montage dieser Drossel zu verringern.The invention was based on the object of providing a spatial interference suppression choke Bring as close as possible to the interferer (coal collector) and the To reduce the cost of manufacturing and assembling this throttle.

Das Problem wird erfindungsgemäß dadurch gelöst, daß eine Drossel direkt in dem Kohlehalter integriert wird. Dies hat den Vorteil, daß die Störstrahler nur aus sehr kleinen Gebilden bestehen (Antennenwirkung) und die Funkenbildung am Kollektor verringert wird.The problem is solved according to the invention in that a throttle directly is integrated in the charcoal holder. This has the advantage that the interference radiators only consist of very small structures (antenna effect) and sparking on the collector is reduced.

Die Drossel besteht aus einem Ferritkern aus magnetisch gut - elektrisch jedoch schlecht - leitenden Material, z.B. einem Nickel-Zink-Ferrit, der drei, ggf. auch fünf, axiale Bohrungen aufweist, durch welche die Anschlußlitze der Kohle mäanderartig hindurchgeführt wird, um so eine Induktivität zu bilden.The choke consists of a ferrite core from magnetically good - electrical but poorly conductive material, e.g. a nickel-zinc ferrite, which has three, possibly also five, axial bores through which the pigtail the carbon is passed through in a meandering manner in order to form an inductance.

Der Kohlehalter ist dergestalt ausgebildet, daß weder die Druckfeder noch das Kontaktstück die integrierte Drossel elektrisch überbrücken können und damit ein Kurzschluß für die Induktivität vermieden wird.The carbon holder is designed in such a way that neither the compression spring nor the contact piece can electrically bridge the integrated choke and thus a short circuit for the inductance is avoided.

Die Abbildung zeigt in drei Ansichten den erfindungsgemäßen Kohlehalter (1) mit Kohle (2) und Entstördrossel (3), Andruckfeder (4), Anschlußlitze (5) und Kontaktstück (6), an dem die Anschlußlitze (5) durch ein übliches Verfahren (Schweißen oder Löten) elektrisch leitend befestigt wird.The figure shows the carbon holder (1) according to the invention in three views with carbon (2) and interference suppression choke (3), pressure spring (4), connecting wire (5) and contact piece (6) to which the pigtail (5) is attached in an electrically conductive manner by a conventional method (welding or soldering).

Die konische Bohrung (7) verhindert, daß die Entstördrossel (3) durch die Andruckfeder (4) und das Kontaktstück (6) überbrückt werden kann.The conical bore (7) prevents the interference suppression throttle (3) through the Pressure spring (4) and the contact piece (6) can be bridged.
