Zweistabwicklung für elektrische Maschinen.
Bei den, üblichen Zweigabwicklungen treten in den den Stromabführungen nächst gelegenen Nuten zwischen Ober-und Unterstab einer Nut Spannungsunterschiede auf, die sich dem Werte der Phasenspannung stark nähern. Dieser Übelstand ist dadurch gemildert worden, dass der Wicklungszug der hintereinander geschalteten Leiter eines Poles erst über einen Teil der einen Lage, dann über sämtliche Leiter der andern Lage und schliesslich über die übrigen Leiter der ersten Lage geführt wurde. Auch bei dieser Anordnung treten aber in den meisten Nuten noch Spanungsunterschiede zwischen den Stäben einer Nut auf, die grösser sind als die Spannung einer Windung.
Nach der Erfindung wird der Spannungsunterschied zwischen den beiden Stäben einer Nut für alle Nuten dadurch gleich der Spannung einer Windung gehalten, dass der 1Vicklungszug der hintereinander- geschalteten Leiter nur in Doppelschleifen geführt wird.
Ein Ausführungsbeispiel hiefür ist in Fig. 1 der Zeichnung veranschaulicht. Diese zeigt eine vier-
EMI1.1
artige Schaltung ist durch Fig. 2 veranschaulicht0
Die Wicklung nach der Erfindung ist nicht nur in solchen Fällen ausführbar, in denen wie bei dem beschriebenen Ausführungsbeispiel die Nutenzahl pro Pol und Phase eine ganze Zahl (z. B. 3) ist, sondern sie lässt sich auch dann ausführen, wenn die Nutenzahl pro Pol und Phase durch eine gebrochene Zahl

der hintereinandergeschalteten Leiter mir in Doppelschleifen (z. B. 1, 2. 1', 2') geführt ist, deren Leiter einem Nutenpaar angehören.

Double handling for electrical machines.
In the usual branch developments, voltage differences occur in the grooves closest to the current conductors between the upper and lower bar of a groove, which differences closely approach the value of the phase voltage. This inconvenience has been alleviated by the fact that the winding pull of the conductors connected in series of a pole was first passed over part of one layer, then over all conductors in the other layer and finally over the remaining conductors in the first layer. Even with this arrangement, however, in most of the grooves there are still differences in stress between the bars of a groove which are greater than the stress in one turn.
According to the invention, the voltage difference between the two bars of a slot is kept equal to the voltage of one turn for all slots in that the winding of the conductors connected in series is only routed in double loops.
An exemplary embodiment for this is illustrated in FIG. 1 of the drawing. This shows a four-
EMI1.1
like circuit is illustrated by FIG
The winding according to the invention can be carried out not only in those cases in which, as in the described embodiment, the number of slots per pole and phase is an integer (z. B. 3), but it can also be carried out when the number of slots per Pole and phase by a fractional number
EMI1.2
the one behind the other connected conductor is led in double loops (e.g. 1, 2, 1 ', 2'), the conductors of which belong to a pair of slots.
