  Triebkern für Ferrariszähler. 



   Die Erfindung gründet sich auf die bekannte Tatsache, dass die Fehlerkurve eines   Ferrariszählers   verbessert wird, wenn die Induktion im Hauptstromeisen niedriger ist als im Spannungseisen. Um dieses   V6rhältnis   der Induktionen bei   dreizinkigen Triebkernen   mit auf den   Aussl3nzinken   angeordneten Stromspulen und auf der   Mittelzinke   angeordneter Spannungsspule zu erreichen, werden nach der Erfindung zum Aufbau des Triebkernes zwei Blechformen verwendet. Die eine Form besitzt alle drei Zinken, die andere nur die beiden Aussenzinken, so dass der Querschnitt des Mittelzinkens kleiner wird als die Querschnitte der Aussenzinken. 



   Die Erfindung ist in den Fig. 1 bis 3 im Aufriss, Grundriss und lotrechten Schnitte dargestellt. Der Triebkern besteht aus zwei Blechpaketen ; das eine enthält Bleche mit drei   Zinken 1, 2   und 5, das andere Bleche, die nur die beiden Aussenzinken 1, 2 besitzen. 



  Die Ansätze 6,7 an den   Aussenzinken dienen   in bekannter Weise zur Erhöhung der Phasendifferenz zwischen Hauptstrom-und Spannungsfeld. 

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

  Drive core for Ferrari meters.



   The invention is based on the known fact that the error curve of a Ferraris meter is improved when the induction in the main current iron is lower than in the tension iron. In order to achieve this induction ratio in three-pronged drive cores with current coils arranged on the external prongs and voltage coils arranged on the central prong, two sheet metal forms are used according to the invention to construct the drive core. One shape has all three prongs, the other only the two outer prongs, so that the cross-section of the central prong is smaller than the cross-sections of the outer prongs.



   The invention is shown in FIGS. 1 to 3 in elevation, plan and vertical sections. The drive core consists of two laminated cores; one contains sheets with three prongs 1, 2 and 5, the other sheets that only have the two outer prongs 1, 2.



  The approaches 6, 7 on the outer prongs serve in a known manner to increase the phase difference between the main current field and the voltage field.
