Description

Polumschaltung «für Mehrphaseninduktionsmotoren. Der im Hauptpatent 357436 angegebenen Polumschaltung für Mehrphaseninduktionsmotoren dient eine Dreiphasenwicklung als Grundlage, bei der in jeder Phase auf jeden Pol eine Spule (oder Windungsgruppe) entfällt und jede Spule je zwei Spulen der beiden anderen Phasen ü'Lergreift. Eine solche Dreiphasenwicklung wird dadurch in eine Zweiphasenwicklung umgeschaltet, daß in jeder Phase der Dreiphasenwicklung die aufeinanderfolgenden Spulen abwechselnd in die eine und andere Phase der Zweiphasenschaltung geschaltet werden, und zwar so, daß in der Zweiphasenschaltung jede Spule die in die gleiche Phase geschalteten zwei Nachbarspulen um j e eine Spulenseitenbreite übergreift, wodurch eine n # 6-polige Zweiphasenwick= lang entsteht.Pole changing «for multiphase induction motors. The one in the main patent 357436 specified pole changing for multi-phase induction motors is a three-phase winding as a basis, in which in each phase a coil (or group of turns) on each pole omitted and each coil overlaps two coils of the other two phases. One such a three-phase winding is switched to a two-phase winding, that in each phase of the three-phase winding the successive coils alternate be switched into one and the other phase of the two-phase circuit, namely so that in the two-phase circuit each coil is connected in the same phase overlaps two adjacent coils by one coil side width each, creating an n # 6-pole Zweiphasenwick = long arises.

Läßt man nun gemäß der Erfindung in der Zweiphasenschaltung die Spulen an der einen Seite mit drei Spulenseitenbreiten übergreifen, am anderen Ende aber in dem Abstande einer Spulenseitenbreite aufeinander folgen, so läßt sich die Polumschaltung auch für das Verhältnis 8 : 6 verwenden.If one now leaves the coils in the two-phase circuit according to the invention on one Overlap side with three spool side widths, on but follow one another at the other end at a distance of one coil side width, so pole changing can also be used for the ratio 8: 6.

Die Zeichnung stellt beispielsweise die in Abb. i des Patentes 357436 angegebene 8-polige Dreiphasenwicklung in eine 6-polige Zweiphasenwicklung umgeschaltet dar, wobei die in die eine Phase der Zweiphasenschaltung geschalteten Spulen mit vollen Linien, die in die andere Phase geschalteten Spulen aber mit gebrochenen Linien gezeichnet sind. Wie hieraus hervorgeht, übergreifen sich zwei benachbarte Spulen, z. B. die Spulen A,, und Ba, an der einen Seite um den Abstand dreier Spulenseitenbreiten, während an der anderen Seite die Spule A8 der Spule A, und die Spule B$ der Spule BZ in dem Abstande einer Spulenseitenbreite folgt.For example, the drawing represents that in Fig. I of patent 357436 specified 8-pole three-phase winding switched to a 6-pole two-phase winding with the coils connected to one phase of the two-phase circuit full lines, the coils switched to the other phase but with broken lines Lines are drawn. As can be seen from this, two adjacent ones overlap Coils, e.g. B. the coils A ,, and Ba, on one side by the distance of three coil side widths, while on the other side coil A8 is coil A, and coil B $ is coil BZ follows in the spacing of a coil side width.

Eine augenblickliche Stromrichtung in den Spulen der mit vollen Linien gezeichneten Phase und die durch diesen Strom erzeugten Pole sind mit Pfeilen angedeutet. Es ist ohne weiteres ersichtlich, daß 6 Pole entstehen. Man kann demnach eine 8-polige Dreiphasenwicklung entweder gemäß Patent 357436 in eine "i2-polige oder gemäß dem vorliegenden Patent in eine 6-polige Zweiphasenwicklung umschalten.An instantaneous direction of current in the coils with full lines drawn phase and the poles generated by this current are indicated with arrows. It is readily apparent that 6 poles are created. You can therefore use an 8-pin Three-phase winding either according to patent 357436 into an "i2-pole" or according to the present patent switch to a 6-pole two-phase winding.
