 Regelung des Widerstandes 12 in Reihe mit dieser Feldwicklung erfolgen kann. 



   Die Wirkung dieser Einrichtung kann in folgender Weise erklärt werden :
Sobald die Stromstärke in der Reglerspule 9 aus irgend einer Ursache von dem Werte, der

 dass die Spannung des   Stromerzeugers   und somit auch die Geschwindigkeit des Motors 2 und der Welle 1 sowie die Spannung der Hilfsmaschine 10 vermindert bzw. vergrössert wird. Die Abnahme oder der Zuwachs setzt sich fort. bis der Gleichgewichtszustand wieder erreicht, d. h. bis der Strom in der   Reglerspule auf seinen   richtigen Wert wieder zurückgeführt worden ist.

   Der selbsttätige Regler 9 regelt somit seine eigene   Stromstärke   auf einen konstanten Wert, und da

 Stromes herbeiführt, so dass der von diesem Strom durchflossene Regler arbeiten kann. bis die eingetroffene Geschwindigkeitsänderung praktisch wieder ausgeglichen worden ist.

 EMI2.1
 Regulation of the resistor 12 can be done in series with this field winding.



   The effect of this facility can be explained in the following way:
As soon as the amperage in the regulator coil 9 for some reason of the values that

 that the voltage of the power generator and thus also the speed of the motor 2 and the shaft 1 as well as the voltage of the auxiliary machine 10 is reduced or increased. The decrease or the increase continues. until the equilibrium is reached again, d. H. until the current in the regulator coil has been returned to its correct value.

   The automatic controller 9 thus regulates its own current strength to a constant value, and there

 Current brings about so that the controller through which this current flows can work. until the change in speed that has occurred has practically been compensated for.
