  Parallelschaltung von Mehrphasen-Serienmotoren mit über Serientransformatoren gespeisten Rotoren. 



   Werden Mehrphasen-Serienmotoren in Parallelschaltung mit über Serientransformatoren   geMpcisten Rotoren betrieben, so   arbeitet die Schaltung nur dann befriedigend, wenn sich der   gesamte,   den Motoren zugeführte Strom auf die einzelnen Motoren ihrer   Grösse   entsprechend verteilt, anderenfalls tritt eine   Überlastung einzelncr Motoren ein.   Die verlangte Stromverteilung besteht auch wirklich, solange die    einzelnenMotorengenau gleichartigsind. Doch genügen   
 EMI1.1 
 der gewünschten wesentlich abweichende Stromverteilung herbeizuführen.

   Durch den Versuch wird dies   bestätigt.   Am gefährlichsten ist die ungleiche Stromverteilung im sekundären Kreis, weil dadurch die empfindlichsten Teile einzelner Motoren, Bürsten und Kollektor überlastet werden. 



   Gegenstand vorliegender Erfindung ist nun eine   Schattung,   bei der dieser Missstand dadurch vermieden wird, dass die Rotoren der einzelnen Motoren in Serie geschattet werden. 



   Ein   Aunführungsbeispiel der   Art zeigt Fig. 1 für Sternschaltung des Stators und sechs-   phasige Rotorapeisung. doch ittt die Schattung auch anwendbar bei   den bekannten Variationen 
 EMI1.2 
 Rotortransformators. Bei   scchsphattiger Speisung von   in Serie geschalteten Rotoren muss bekanntlich die Sekundärwicklung des Rotortransformators in ebenso viele Teile unterteilt sein,

  Parallel connection of multi-phase series motors with rotors fed by series transformers.



   If multi-phase series motors are operated in parallel with rotors driven by series transformers, the circuit only works satisfactorily if the entire current supplied to the motors is distributed to the individual motors according to their size, otherwise individual motors will be overloaded. The required power distribution really exists as long as the individual motors are exactly the same. But enough
 EMI1.1
 to bring about the desired significantly different current distribution.

   This is confirmed by the experiment. The most dangerous is the uneven distribution of current in the secondary circuit, as it overloads the most sensitive parts of individual motors, brushes and collectors.



   The subject matter of the present invention is a shading in which this deficiency is avoided by shading the rotors of the individual motors in series.



   An exemplary embodiment of this type is shown in FIG. 1 for star connection of the stator and six-phase rotor output. but the shading is also applicable to the known variations
 EMI1.2
 Rotor transformer. When it comes to the supply of rotors connected in series, it is known that the secondary winding of the rotor transformer must be divided into as many parts as
