Bei einem   Zahler,   der mit der vorbeschriebenen Einrichtung versehen ist, erhält nun der Anker ein zusätzliches   Drehmoment, je weiter   die Belastung sinkt. Diese entsteht dadurch, 
 EMI2.1 
 der   Strom im Widerstand W sinkt.

   Dabei kommen   die Bürsten B,   BX in eille tiefere   Lage zum   Kommutator,   und infolge der   schraubenförmig   verlaufenden Lamellen wird in diesen Stellungen die gegenseitige Lage der Linien des   Ankorkraftfeldes   zu den Kraftlinien des permanenten Magneten günstiger, oder das durch die Verschiebung der Kommutierungslage um ein ent- 
 EMI2.2 
 und es ist leicht zu ersehen, dass durch geeignet, e Bemessung der wirkenden Teile die Eichkurve des   Zählers   ohne Schwierigkeit innerhalb 1 Prozent für jeden Punkt der Belastung konstant gehalten werden kann. 



   Zur Erzielung eines sicheren Anlaufs bei den geringsten Belastungen ist diese Einrichtung bei   Amperestundenz l1lern   besonders vorteilhaft, und es kann infolgedessen die   Windungs-   zahl und das Gewicht des Ankers verringert sowie auch der Strom, der durch den Anker fliesst, kleiner gehalten werden, wodurch der Kommutator wesentlich geschont wird. 



   Fig. 2 zeigt eine andere Schaltungsart der Spule'S ; dieselbe ist in diesem Falle parallel zum Anker geschaltet. 



   PATENT-ANSPRÜCHE : 
1. Amperestundenzähler mit im   permanenten   Magnetfeld umlaufendem Anker, dadurch 
 EMI2.3 
 als zusätzliche Kraft zur Wirkung kommt.

In the case of a payer that is provided with the device described above, the armature receives an additional torque the further the load decreases. This arises from
 EMI2.1
 the current in the resistor W decreases.

   The brushes B, BX come in a lower position to the commutator, and as a result of the helical lamellas, the mutual position of the lines of the anchor force field to the lines of force of the permanent magnet is more favorable in these positions, or by shifting the commutation position by a
 EMI2.2
 and it is easy to see that by appropriately dimensioning the acting parts, the meter's calibration curve can be kept constant within 1 percent for each point of loading without difficulty.



   In order to achieve a reliable start with the lowest loads, this device is particularly advantageous when learning ampere hours, and as a result, the number of turns and the weight of the armature can be reduced, and the current flowing through the armature can also be kept smaller, thereby reducing the commutator is significantly spared.



   Fig. 2 shows another type of circuit of the coil'S; the same is connected in parallel to the armature in this case.
