  Kollektor für elektrische Maschinen. 



   An denjenigen Stellen der Kollektoroberfläche, welche weder von den Borsten be strichen noch durch Isolationsmaterial geschützt sind, sammelt sich leicht Staub an, der, wenn er leitend ist, unter Umständen die schmalen Isolationslamellen   überbrückt. Ins..   besondere kann es bei den Innenflächen raschlaufender Kollektoren vorkommen, dass sich infolge der Zentrifugalkraft leitende Teilchen quer über die Isolationslamellen legen und zwei leitende Lamellen   kurzschliessen.   



   Um derartige   Missstände   zu verhüten, ist man bestrebt, grosse isolierende Flächen zwischen den stromführenden Metallamellen zu schaffen, was durch Verlängerung der Isoiationslamellen nach der Innenseite des Kollektors zu erzielt wird. 



   Um beträchtliche Verlängerungen der   Isolationslamellen   zu erzielen, ist es nötig, die freien Enden mechnisch zu versteifen, was mit vorliegender Erfindung erreicht wird, und zwar dadurch, dass jede zweite   Metallamelle   nach innen verlängert wird und sich die dünnen freien Enden der Isolationssegmente auf diese Metallamellen abstützen. 



   Die Figur zeigt einen Ausschnitt aus einem Kollektor mit kurzen Metallamellen   a,   langen Metallamellen b und langen Isolationalamellen o.

  Collector for electrical machines.



   At those points on the collector surface that are neither coated by the bristles nor protected by insulation material, dust easily collects, which, if conductive, may bridge the narrow insulation lamellas. In particular, it can happen with the inner surfaces of rapidly rotating collectors that, as a result of centrifugal force, conductive particles lay across the insulation lamellae and short-circuit two conductive lamellae.



   In order to prevent such problems, efforts are made to create large insulating surfaces between the current-carrying metal lamellas, which is achieved by extending the insulating lamellae towards the inside of the collector.



   In order to achieve considerable extensions of the insulation lamellas, it is necessary to stiffen the free ends mechanically, which is achieved with the present invention, namely in that every second metal lamella is extended inward and the thin free ends of the insulation segments are supported on these metal lamellas .



   The figure shows a section of a collector with short metal slats a, long metal slats b and long insulating slats o.
