konstant. Eine kleine weitere Steigerung der Drehzahl bewirkt ein Fallen des von der Zentrale gelieferten Stromes bis auf den Betrag der Leerlaufarbeit, da infolge der Zunahme der Drehzahl und des zusätzlichen Feldes die elektromotorische Gegenkraft steigt.
Wird die Arbeitsmaschine jetzt wieder belastet, so sinkt die Drehzahl des Motors. Der von der Zentrale gelieferte Strom erreicht wiederum seinen Höchstwert, bei welchem der Spannung- abfall an den Klemmen des Hauptstromfeldes die elektromotorische Kraft der zusätzlichen Strom- quelle e übersteigt. Hier würde sich der Strom in diesem Kreise umkehren, wenn nicht das elektrische Ventil t'eingebaut wäre. Da dieses aber den Mehrstrom absperrt, so muss bei weiterem Anwachsen des Stromes dieser durch das Hauptfeld. Der Motor hat also wieder die Eigenschaften des Hauptmotors bei sinkender Drehzahl angenommen.

constant. A small further increase in the speed causes the current supplied by the control center to drop to the amount of idle work, since the counter electromotive force increases due to the increase in speed and the additional field.
If the machine is now loaded again, the speed of the motor drops. The current supplied by the control center in turn reaches its maximum value at which the voltage drop at the terminals of the main current field exceeds the electromotive force of the additional current source e. Here the current in this circuit would be reversed if the electric valve t 'were not installed. However, since this blocks the additional flow, it must pass through the main field as the flow increases. The motor has thus again assumed the properties of the main motor with decreasing speed.
