  Wechseistrominduktionsmotorzähler. 



     'Es sind Wochielstrommotorzähler bekannt,   bei denen sich Strom-und Spannungs. feld mischen,   Diele      Zähle1'haben   zumeist den Nachteil, dass die Fehlerkurve bei geringer Last wesentlich von einer geraden Linie abweicht
Die vorliegende Erfindung hat nun den Zweck, durch eine besonders günstige Anordnung der   Spannungsspule   und der Stromspulen die magnetischen Verhältnisse so zu gestalten, dass die Fehlerkurve auch bei geringer Last einen geradlinigen Verlauf hat. 



   Eine Ausführung des Erfindungsgegenstandes zeigt die Figur. 



   Der dreizinkige Triebkern 1 trägt auf einem Mittelzinken 2 eine Spannungsspule   9.   



  Zwischen dem Mittelzinken 2 und den Aussenzinken 4 und 5 sind magnetische Bracken 6 und 7 vorgesehen, durch welche ein magnetischer Nebenschluss für das Feld der Spannungsspule gebildet wird. Dieser magnetische Nebenschluss ist unvollkommen gemacht, indem entweder Lufträume vorgesehen sind oder Stücke 8 aus Isoliermaterial zwischengelegt sind. 



   Auf den Enden der Aussenzinken sitzen oberhalb der magnetischen Brücken 6 und 7 die Stromspulen 9 und 10. 11 ist die Ferrarisscheibe. Auf der anderen Seite derselben befindet sich das   Schlnssatssck   12. Auf dem Mittelzinken befindet sich ein verstellbarer   Kurzschlussring   13. 



   Durch diese neue Anordnung wird der obenbezeichnete Effekt in vollkommenster Weise erreicht, im Gegensatz zu den bekannten Zählern. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  AC induction motor meter.



     'There are Wochielstrommotorcounter known, in which current and voltage. Mix field, plank count1 'usually have the disadvantage that the error curve deviates significantly from a straight line when the load is low
The present invention now has the purpose of designing the magnetic conditions through a particularly favorable arrangement of the voltage coil and the current coils so that the error curve has a straight course even with a low load.



   The figure shows an embodiment of the subject matter of the invention.



   The three-pronged drive core 1 carries a voltage coil 9 on a central prong 2.



  Magnetic brackets 6 and 7 are provided between the central prongs 2 and the outer prongs 4 and 5, by means of which a magnetic shunt is formed for the field of the voltage coil. This magnetic shunt is made imperfect by either providing air spaces or interposing pieces 8 of insulating material.



   On the ends of the outer prongs sit the current coils 9 and 10 above the magnetic bridges 6 and 7. 11 is the Ferraris disc. The key assembly 12 is located on the other side of the same. An adjustable short-circuit ring 13 is located on the central prong.



   With this new arrangement, the above-mentioned effect is achieved in the most perfect way, in contrast to the known counters.
