   gleichem   Querschnitte ungleich belastet, während eine verschiedene Bemessung der einzelnen Abschnitte den Aufbau verwickelter macht und die Maschine verteuert. Diese Nachteile vermeidet die oben angegebene Regelung durch Änderung des   Transformatorübersetzungsverhältnisses   oder durch im Erregerkreis liegende Widerstände, welche noch den weiteren Vorteil hat, dass sie auch dann anwendbar ist, wenn die Erregerwicklung mit der Arbeitswicklung kombiniert ist. 



   Maschinen nach den im Vorhergehenden beschriebenen Anordnungen können sowohl als Motor als auch als Stromerzeuger laufen, wodurch unter anderem die Möglichkeit der Bremsung gegeben ist.

   The same cross-sections are unevenly loaded, while a different dimensioning of the individual sections makes the structure more complex and makes the machine more expensive. The above regulation avoids these disadvantages by changing the transformer transformation ratio or by using resistors in the exciter circuit, which has the further advantage that it can also be used when the exciter winding is combined with the working winding.



   Machines according to the arrangements described above can run both as a motor and as a power generator, which, among other things, gives the possibility of braking.

Claims

Device for the excitation and regulation of single-phase collector machines, each with a working winding on the stator and rotor of approximately the same axis, the latter of which is designed as a collector winding with brushes, and one combined with the stator winding or separately from it arranged on the stator with an excitation winding against the axis of the Arbeitswicklullg axis offset by half a pole pitch, with one of the working windings being short-circuited to itself or to resistors of any kind, while the other working winding and the exciter winding are externally working respectively.

Excitation voltage is supplied, characterized in that the excitation winding is fed from the secondary circuit ewes in the main circuit connected series transformer, or from a voltage which is the resultant of the secondary voltage of a series and a parallel transformer, in all cases this excitation circuit by resistance or by change the transformation ratio of the transformers can be regulated and reversed by a common changeover switch.
