Description

Es sind neuerdings Drähte mit dünner hochwertiger Isolation bekanntgeworden, die ohne tutisolation den elektrischen Beanspruchungen standhalten könnten, aber der mechanischen Beanspruchung beim Einführen in die Nut nicht immer gewachsen sind.Recently, wires with thin, high-quality insulation have become known, which could withstand electrical stresses without insulation, but are not always able to cope with the mechanical stress when inserting them into the groove.

Um nun trotzdem solche Leiter unmittelbar in die Nut einführen zu können, versieht man erfindungsgemäl-4 wenigstens einen Teil der zwischen den Blechlamellen befindlichen Isolierblätter mit über die Nutenwände vorstehenden Rändern. Diese überstehenden Blattränder werden am besten eingeschnitten. Es sind zwar Stromwender für elektrische Maschinen be-kannt. bei denen zwischen den einzelnen Stegen angeordnete Glimmerscheiben über die eine Stirnfläche des Stromwenders hinausragen. Diese Maßnahme soll jedoch eine völlig andere Aufgabe- läsen. nämlich beim späteren Einlöten der Wicklungsenden eine leitende Verbindung zwischen zwei benachbarten Stegen durch abfließendes Lot zu vermeiden.In order to introduce such conductors directly into the groove anyway can, according to the invention, at least a part of the between the sheet metal lamellas is provided located insulating sheets with over the groove walls protruding edges. These protruding leaf margins are best cut. It is true that they are commutators known for electrical machines. those arranged between the individual webs Mica washers protrude beyond one end face of the commutator. This measure should, however, have a completely different task. namely when soldering in the later Winding ends through a conductive connection between two adjacent webs to avoid flowing solder.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Ff-. i zeigt einen Teil des Ständerblechpaketes mit der Nut i, den Zähnen 2 und den überstelinden Blatträndern 3; Fig. 2 zagt das Blechpaket von innen gesehen; Fig. 3 zeigt, wie sich die überstellenden Ränder 3 beim Einführen der Leiter .1 umlegen und wie ein Schutzbelag den Leiter gegen Berührung mit den scharfkantigen S tanzrändern der Bleche schützen. Ff-. i shows part of the stator core with the groove i, the teeth 2 and the overlapping sheet edges 3; 2 shows the laminated core seen from the inside; Fig. 3 shows how the transferring edges 3 fold over when inserting the conductor .1 and protect the conductor against contact with the sharp edges of the metal sheets like a protective covering.

Es genügt. wenn beispielsweise, wie in g 3 iew'-'ls auf eine Anzahl von Blechen , - , - ei ein Isolierblatt mit itb°rstehenden Rändern folgt. Diese Blätter kiJ innen aus Papier, Film oder ähnlichem -Material bestehen.It is sufficient. if, for example, as in g 3 iew '-' ls, a number of metal sheets , -, - ei are followed by an insulating sheet with protruding edges. The inside of these sheets may consist of paper, film or similar material.

Die Erfindung bietet den Vorteil. daß elektrisch hoch isolierte Leiter. z. B. solche, die in mehrfache Schichten mit sehr dünnem Film umhüllt sind, unmittelbar in die Nuten eingebracht «erden können. ohne daß sie mit den scharfen Blechkanten in Berührung kommen.The invention offers the advantage. that electrically highly insulated conductor. z. B. those that are wrapped in multiple layers with a very thin film, directly brought into the grooves «can be grounded. without them with the sharp metal edges come into contact.
