    Nachstehend ist eine Anordnung beschrieben, welche konstante Spannung eines   Generators bei veränderlicher   Umlaufzaht   durch geeignete Schaltung der Anker-und Feldmagnetwindungen der zu regulierenden und dreier kleiner Hilfsmaschinen geeigneter Bauart ergibt. Hiebei wird das Vorhandensein wenigstens einer Hilfsstromquelle mit möglichst konstanter Spannung vorausgesetzt.

  Der Anker des Generators B speist die Feldmagnete des Motors C, der Anker des   Generators A)   liefert Strom für die eldmagnete des Generators A, dessen Anker auf konstante Spannung reguliert werden soll. 



     Lässt man   die Garnitur A-B laufen, so liefert der Anker des Generators B zunächst

Steigt die Umlaufzahl der Garnitur A-B beispielsweise auf die doppelte, so liefert der Generator B infolge konstanter Erregung doppelte Spannung, der Motor C erhält daher doppelte Erregung, wodurch seine Tourenzal auf die Hälfte sinkt.

   Die Spannung des Generators D ist zufolge   halber Tourenzahl bei konstanter   Erregung die Hälfte, somit auch   die Erregung   der   Maschine ,   die Maschine A ergibt aber bei doppelter   Umtanfzaht   und

Es ist dabei   selbst\ erfindlich,   dass der Generator.A ebensowohl eine Gleichstromals auch eine ein- oder mehrphasige Wechselstrommaschine sein kann. Ebenso   können   die Schenkelwicklungen der Maschinen B und D sowie der Anker des Motors C von ver-   schiedenen   Stromquellen mit verschiedener, aber konstanter Spannung gespeist werden.

 EMI1.2
 



    An arrangement is described below which produces a constant voltage of a generator with a variable number of revolutions by suitable switching of the armature and field magnet windings of the three small auxiliary machines to be regulated and of suitable design. The presence of at least one auxiliary power source with a voltage that is as constant as possible is assumed.
 EMI1.3
 



  The armature of generator B feeds the field magnets of motor C, the armature of generator A) supplies current for the field magnets of generator A, whose armature is to be regulated to constant voltage.



     If the set A-B is allowed to run, the armature of the generator B initially delivers
 EMI1.4
 comes into operation and driving the generator 7) also excites the field magnets of machine A.
 EMI1.5
 
If the number of revolutions of the set A-B increases to double, for example, the generator B delivers double the voltage as a result of constant excitation, the motor C therefore receives double the excitation, which reduces its speed by half.

   The voltage of the generator D is half the number of revolutions with constant excitation, thus also the excitation of the machine, the machine A results in double number of revolutions and
 EMI1.6
 Completely self-regulating and enables constant tension at armature A with an increase up to a multiple of that depending on the type of machine A and D.
 EMI1.7
 
It is even inventive that the generator.A can be a direct current as well as a single or multi-phase alternating current machine. Likewise, the leg windings of machines B and D and the armature of motor C can be fed from different power sources with different but constant voltages.
