Description

  

  Einrichtung an Kollektoren elektrischer     Naschinen    zur Vermeidung  von     lamellenschlüssen,       Elektrische Maschinen, deren Kollektor  durchmesser kleiner als der zugehörige An  kerdurchmesser ist, werden in der Regel so  ausgeführt, dass an den     Kollektorlamellen     sogenannte Fahnen angebracht werden, um  die Wicklungsstäbe     wagrecht    zum Kollektor       zli    führen.

   Diese Kollektoren werden vor  dem Zusammenbau der Maschinen     bezw.    vor  Einlegen der Wicklung auf der Stirnseite,  wo die Fahnen eingelötet werden, nochmals       iiberdreht,    um eventuell durch das Löten  verkohlte     Lamellenisolation    (Schellack) zu  entfernen.  



  Bei     Maschinen,    deren     Kollektordurchmes-          ser    gleich dem Ankerdurchmesser oder nur  wenig vom Ankerdurchmesser verschieden  ist, kann diese Bearbeitung nicht mehr aus  geführt werden. Es ist deshalb für solche  Maschinen eine gewisse Gefahr vorhanden,  dass im Betriebe Defekte infolge     Windungs-          schluss        bezw.    Schluss einzelner Lamellen auf  treten.    Die     Erfindung    gibt eine Einrichtung an  Kollektoren an, welche diese     Windungs-          bezw.        Kollektorlamellenschlüsse    der beschrie  benen Art vermeiden soll.

   Erfindungsge  mäss wird die     Lamellenisolation    auf der       Wicklungsanschlussseite    des Kollektors um  das mehrfache der     Lamellenisolationsdicke     vorstehend ausgeführt, wodurch der Kriech  weg zwischen den     Kollektorlamellen    etwa  verzehnfacht werden kann, wie aus den bei  liegenden Figuren, die ein Ausführungsbei  spiel des     Erfindungsgegenstandes    in Seiten  ansicht und in Draufsicht zeigen, ersichtlich  ist. 1 sind die     Kollektorlamellen,    2 ist     die          Lamellenisolation,    und 3 sind Stäbe der       Ankerwicklung.  



  Equipment on collectors of electrical machines to avoid lamella closures, electrical machines whose collector diameter is smaller than the associated anchor diameter are usually designed in such a way that so-called flags are attached to the collector lamellae so that the winding bars lead horizontally to the collector.

   These collectors are BEZW before assembling the machines. Before inserting the winding on the front side where the flags are soldered in, turn it over again in order to remove any lamellar insulation (shellac) that may have been charred by soldering.



  This processing can no longer be carried out on machines whose collector diameter is the same as the armature diameter or only slightly different from the armature diameter. There is therefore a certain risk for such machines that defects as a result of interturn short circuits or The end of individual slats occurs The invention specifies a device on collectors, which these Windungsbezw. Collector lamella connections of the type described should be avoided.

   According to the invention, the lamellar insulation on the winding connection side of the collector is carried out by a multiple of the lamellar insulation thickness above, which means that the creep away between the collector lamellas can be increased tenfold, as can be seen from the enclosed figures, which show an exemplary embodiment of the subject matter of the invention in side and top view can be seen. 1 are the collector lamellas, 2 is the lamellar insulation, and 3 are the rods of the armature winding.

PATENTANSPRUCH: Einrichtung an Kollektoren elektrischer Masehinen zur Vermeidung von Lamellen- Schlüssen, dadurch gekennzeichnet, dass die Lamellenisolation auf der Wicklungsan- schlussseite des Kollektors um das mehrfache der Lamellenisolationsdicke vorsteht, zu dem Zwecke, daselbst den Kriechweg zwischen den Kollektorlamellen zu vergrössern. Claim: device on collectors of electrical machines to avoid lamellar shortings, characterized in that the lamellar insulation on the winding connection side of the collector protrudes by several times the lamellar insulation thickness, for the purpose of increasing the creepage distance between the collector lamellas.
