 Schlitz 12 geteilt und mit einem Flansch 6 versehen, welcher die Spulen in ihrer Lage festhält. Die Hilfspole sind mit je einer in sich geschlossenen oder   Kurzschlussspule 8   ausgestattet, die aus zwei Windungen besteht, welche 8-förmig zusammengestellt sind (Fig. 4) und von denen jede einen Schenkel   9,   10 des gespaltenen Endes des Hilfspoles umgibt. 



   Vermöge dieser Anordnung der Kurzschlussspule 8 wirken ihre beiden Windungen einander entgegen und erzeugen unter normalen Umständen, wenn nämlich der von der Spule 5 erzeugte   Kraftfluss   vorherrscht, keine wahrnehmbare Wirkung. Sie setzen aber den Durchgang der Kraftlinien aus den Zahn 13 des Motorankers durch einen der Schenkel des gespaltenen Hilfspoles und zurück durch den anderen Schenkel in den anderen Zahn 15 des Ankers einen sehr beträchtlichen Widerstand entgegen. Die Wirkung erklärt sich sehr leicht aus Fig. 5, in welcher die Kurzschlussspule 8 aus zwei Windungen von gewöhnlichem Runddraht besteht.

   Das Ende des Hilfspolschuhes ist dabei mit einem Schlitz. 11 zur Aufnahme der Kurzschlussspule versehen und ferner verstärkt,

 Fig. 4 gezeigten Einrichtung, welche die gewöhnliche Anordnung der Kommutierspule ermöglicht, der Vorzug gegeben. Diese Kurzschlussspule kann aus Blech hergestellt sein und wenn sie auf das   Polstück   aufgeschoben ist, so bildet sie im allgemeinen zwei hohle. rechteckige Prismen, deren einander zugekehrte Seiten in den Schlitz 12 zwischen den beiden Schenkeln    des'Polstück-es   liegen. Diese Seiten sind, wie Fig. 4 zeigt nur halb so hoch, wie die Prismen und es geht immer eine Seite von einem Prisma zum anderen. 



   Die baulichen Einzelheiten können natürlich abgeändert werden, ohne vom Wesen der Erfindung abzuweichen.

 EMI2.1
 Split slot 12 and provided with a flange 6 which holds the reels in place. The auxiliary poles are each equipped with a self-contained or short-circuit coil 8, which consists of two turns which are arranged in an 8-shape (FIG. 4) and each of which surrounds a leg 9, 10 of the split end of the auxiliary pole.



   By virtue of this arrangement of the short-circuit coil 8, its two turns counteract one another and, under normal circumstances, namely when the flow of force generated by the coil 5 prevails, do not produce any noticeable effect. However, they oppose the passage of the lines of force from tooth 13 of the motor armature through one of the legs of the split auxiliary pole and back through the other leg into the other tooth 15 of the armature. The effect can be explained very easily from FIG. 5, in which the short-circuit coil 8 consists of two turns of ordinary round wire.

   The end of the auxiliary pole piece has a slot. 11 provided to accommodate the short circuit coil and also reinforced,

 4, which enables the usual arrangement of the commutation coil, given preference. This short-circuit coil can be made of sheet metal and when it is pushed onto the pole piece, it generally forms two hollow ones. rectangular prisms, the mutually facing sides of which lie in the slot 12 between the two legs of the pole piece. As shown in FIG. 4, these sides are only half as high as the prisms and one side always goes from one prism to the other.



   The structural details can of course be changed without departing from the essence of the invention.
