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.
