   Bei den in den Fig. 2 und 3 dargestellten Ausführungsformen sind die Kurzschlussscheiben 8 an der den Luftspalten 7 zunächstliegenden Stirne der Magnetwicklung 1 unverschiebbar befestigt. 



   Zwecks Erzielung einer festen Verbindung mit der Spule können die   Kurzschlussseheiben   8 bei-

 von mit Flanschen versehenen   Spulenhülsen,   in   die Flansche eingebettet, insbesondere miteingepresst   oder in sonstiger   Weise   unverschiebbar an dem Spulenkörper befestigt sein. 



   Die Wirkungsweise ist folgende : Einerseits wirken die Kurzschlusscheiben wegen ihrer elektrischen   Leitfähigkeit   als sekundäre Bürde für den Gesamtfluss. wodurch in an sieh bekannter Weise die 90-Grad-
Abgleichung herbeigeführt wird; anderseits vergrössern sie wegen ihrer   magnetiscien Leitfähigkeit   den Streufluss. Hat die Magnetwicklung 1 beispielsweise die in Fig.   2   dargestellte Lage gegenüber dem 
 EMI2.2 
 als beim Anliegen der unteren Spulenstirne an den Teilen   J.   Es   würde sich   also bei   dun   in Fig. 2 dar- gestellten Spulensitz wegen der höheren Streuung des Magnets ein kleineres Drehmoment ergeben, als wenn die Spule weiter nach unten   geliich1   würde. 



  Andererseits würde, wenn die Wicklung in der Lage der Fig. 2 festgehalten   würde,   die Kurzschluss- scheibe 8 dagegen verschiebbar wäre. in der gezeichneten Lage der   Kurzschlussscheibe   der in sie über- tretende Fluss   ldeiner   sein als in der Lage, wo die Kurzsehlussseheibe an den Teilen 3 anliegt.

   In the embodiments shown in FIGS. 2 and 3, the short-circuit disks 8 are non-displaceably attached to the face of the magnet winding 1 lying next to the air gaps 7.



   To achieve a firm connection with the coil, the short-circuit washers 8 can be
 EMI2.1
 of bobbin sleeves provided with flanges, embedded in the flanges, in particular pressed in or fastened in some other non-displaceable manner to the bobbin.



   The mode of operation is as follows: On the one hand, the short circuit disks act as a secondary burden for the overall flow due to their electrical conductivity. whereby the 90-degree
Alignment is brought about; on the other hand, because of their magnetic conductivity, they increase the leakage flux. Has the magnet winding 1, for example, the position shown in Fig. 2 relative to the
 EMI2.2
 than when the lower end of the coil is in contact with parts J. In the case of the coil seat shown in FIG. 2, because of the greater scatter of the magnet, a smaller torque would result than if the coil were adjusted further downwards.



  On the other hand, if the winding were held in the position of FIG. 2, the short-circuit disk 8 would, on the other hand, be displaceable. In the position of the short-circuit disk as shown, the flow that flows into it must be less than in the position where the short-circuit disk rests on the parts 3. It would
 EMI2.3
 shift along the magnetic leg 2 and with correct adjustment of the magnetic conditions, the two above-mentioned effects on each other. d. H. the voltage magnet is insensitive to the winding displacement.
