sind in beliebiger Weise, z. B. starr miteinander verbunden. Die Hilfswicklung o ist in solchem Sinne geschaltet, dass sie die Hauptwicklung b unterstützt, und der Regler I ist'so angeordnet, dass die durch die Hi1fswicklung c verursachte Magnetisierung abnimmt, während die Magnetisierung der Anlassmaschine durch die Feldwicklung a wächst. Der Regler f dient beispielsweise dazu, einen der Wicklung c vorgeschalteten Widerstand stufenweise zu vergrössern (Fig. 1) oder die Windungszahl der Hilfsmaschine c stufenweise zu verringern (Fig. 2).
Bei dem Ausführungsbeispiel der Fig. 3 ist die hier mit c'bezeichnete Hilfswicklung des Motors entgegengesetzt der Hauptfeldwicklung b geschaltet. In diesem Falle muss die durch die Hi1fswickhmg c'verursachte Gegenmagnetisierung des Motors gleichzeitig mit der Magnetisierung der Anlassmaschine 9 durch die Feldwicklung a wachsen. Man kann daher in diesem Falle unter Fortfall jedes besonderen Reglers für die Hilfsfeldwicklung letztere mit der Feldwicklung a der Anlassmaschine einfach zusammenschalten, sei es in Reihe, wie Fig. 2 zeigt, oder parallel. Es darf nicht übersehen werden, dass diese Anordnung mehr Feldkupfer erfordert und grössere Erregerverluste aufweist als die Anordnungen nach Fig. 1 und 2.
Selbstverständlich können die einzelnen Anordnungen auch vereinigt werden. So kann man insbesondere die Einrichtung auch so treffen, dass die Hilfsfeldwicklung des Motors anfänglich die Hauptfeldwicklung b unterstützt und später ihr entgegenwirkt. In diesem Falle

PATENT-ANSPRÜCHE :
1. Einrichtung zur Regelung von Elektrorr-agneten, insbesondere für den Antrieb von Fördermaschinen, durch Änderung der dem Anker zugeführten Spannung unter Verstärkung des Magnetfeldes für niedrige Ankergeschwindigkeiten, dadurch gekennzeichnet, dass der Motor ausser der von einer konstanten Stromquelle gespeisten Hauptfeldwicklung eine ebenfalls von einer konstanten Stromquelle erregte Hilisfeldwicklung besitzt, die gleichzeitig mit der Feldwicklung der Anlassmaschine aber unabhängig von der Grösse der Last geregelt wird.

are in any way, e.g. B. rigidly connected to each other. The auxiliary winding o is connected in such a way that it supports the main winding b, and the regulator I is arranged in such a way that the magnetization caused by the auxiliary winding c decreases, while the magnetization of the starting machine through the field winding a increases. The controller f is used, for example, to gradually increase a resistor connected upstream of the winding c (FIG. 1) or to gradually reduce the number of turns of the auxiliary machine c (FIG. 2).
In the exemplary embodiment in FIG. 3, the auxiliary winding of the motor, denoted here by c ', is connected opposite to the main field winding b. In this case, the counter-magnetization of the motor caused by the auxiliary winding c ′ must increase simultaneously with the magnetization of the starting machine 9 by the field winding a. In this case, therefore, with the omission of any special regulator for the auxiliary field winding, the latter can simply be connected to the field winding a of the starting machine, be it in series, as FIG. 2 shows, or in parallel. It should not be overlooked that this arrangement requires more field copper and has greater excitation losses than the arrangements according to FIGS. 1 and 2.
Of course, the individual arrangements can also be combined. In particular, the device can also be designed in such a way that the auxiliary field winding of the motor initially supports the main field winding b and later counteracts it. In this case

PATENT CLAIMS:
1. A device for the control of Elektrorr-agneten, in particular for the drive of hoisting machines, by changing the voltage supplied to the armature with amplification of the magnetic field for low armature speeds, characterized in that the motor in addition to the main field winding fed by a constant power source also from a constant current source excited Hilisfeld winding, which is regulated simultaneously with the field winding of the starting machine but regardless of the size of the load.
