Aus Profillackdrähten gebildete Wicklungsspulen, elektrischer Maschinen Winding coils formed from enameled wire, electrical machines
Verwendet man bei der Herstellung von Wicklungsspulen elektrischer Maschinen Profillackdrähte, insbesondere lackierte Kupferflachdrähte, dann können beim Biegen derselben sowie auch beim Einlegen in die Nuten Fehlerstellen in der Lackschioftt auftreten. Diese Fehlerstellen wiederum können in den aufeinander liegenden Drähten zu Windungsschlüssen und damit zum Ausfall der Maschine führen.Used in the manufacture of winding coils electrical Machines profile enameled wires, especially enamelled flat copper wires, can then be used when bending them as well as when Inserting into the grooves, defects in the paintwork occur. These faults in turn can lead to shorted turns in the wires lying on top of one another and thus to failure of the machine to lead.
Um diese Ausfallmöglichkeit zu verhindern, schlägt die Neuerung vor, daß wenigstens einer von jeweils zwei nebeneinander liegenden Leitern mit einem Gewebeschlauch überzogen ist. Dieser auf die ganze Länge des Leiters aufgezogene Schlauch ergibt einen Abstandhalter zu den beiden angrenzenden Leitern, so daß auch bei Fehlerstellen in den Lackschichten der Drähte keine Windungs-Schlüsse auftreten können. Beim Imprägnieren der fertigen Wicklung nehmen die Gewebeschläuche Harz auf, so daß auch zwischen den einzelnen Leiterdrähten eine einwandfreie Isolation vorhanden ist und außerdem die Wicklung zu einem festen Verband zusammenbackt. In order to prevent this possibility of failure, the innovation suggests that at least one of two adjacent ones Ladders is covered with a fabric tube. This hose drawn over the entire length of the conductor results in one Spacer to the two adjoining conductors, so that even if there are flaws in the lacquer layers of the wires, there are no turns may occur. When the finished winding is impregnated, the fabric hoses absorb resin, so that between the individual conductor wires are properly insulated and the winding is also caked to form a firm association.
Zweckmäßig bestehen die Gewebeschläuche aus einem Glasfasergewebe. Dies hat den zusätzlichen Vorteil, daß bei starker Erwärmung der Wicklung sowie auch bei Schweiß- oder Lötbearbeitung der Glasfaserschlauch erhalten bleibt, während die organischen Drahtlacke stark beschädigt werden können.The fabric tubes expediently consist of a glass fiber fabric. This has the additional advantage that when the winding becomes very hot and also when welding or soldering the Fiberglass tubing is retained while the organic wire enamels can be severely damaged.

In den Fig. 1 und 2 besteht die Wicklungsspule aus drei Leitern 1,2 und 3 aus lackiertem Kupferflachdraht. Mit a ist in Fig. 1 der Spulenteil bezeichnet, welcher in den Nuten der Maschine liegt. 4 ist ein die Leiterdrähte aufnehmender Spulenkasten.In Figs. 1 and 2, the winding coil consists of three conductors 1, 2 and 3 made of lacquered flat copper wire. With a in Fig. 1, the coil part is referred to, which in the grooves of the machine located. 4 is a coil box accommodating the lead wires.
Gemäß der Neuerung ist der mittlere Leiter 2 mit einem Schlauch 5 aus Glasfasergewebe überzogen, der zwischen den einzelnen Leitern einen Abstandhalter bildet, welcher bei Beschädigung des Drahtlackes Windungsschlüsse verhindert.According to the innovation, the middle conductor 2 is covered with a tube 5 made of glass fiber fabric, which is between the individual conductors forms a spacer which prevents interturn short circuits if the wire enamel is damaged.
In dem Ausführungsbeispiel nach Fig. 3 sind alle drei Leiter 6, 7 und 8 mit je einem Schlauch 5 überzogen.In the exemplary embodiment according to FIG. 3, all three conductors 6, 7 and 8 are each covered with a hose 5.
