Description

  

  Mehrphasenkommutatormaschine mit einer im Ständer untergebrachten und vom  Anker durch Induktion gespeisten Wicklung.  
EMI0001.0000     
  
       Induktion gespeisten Wicklung (Käfig- oder  Phasenwicklung) derart gegeneinander ab  geglichen sein, dass Selbsterregung eintritt.  Wie die Versuche gezeigt haben, lässt sich  die Selbsterregung in jedem Falle durch  richtige Bemessung des Ohmschen Wider  standes der Ständerwicklung erreichen. Die  mathematischen Angaben, aus denen her  vorgeht, wie das erforderliche Verhältnis  zwischen dem Ohmschen und dem induk  tiven Widerstand zwecks Selbsterregung der  Kommutatorhintermaschine in jedem Falle  hergestellt werden kann, sind in dem Artikel  von Brüderlin: ,Drehstromerregermaschine  als selbständiger Generator von Schwingun  gen kleiner Frequenz" in der Zeitschrift  ,Archiv für Elektrotechnik", Jahrg. 1925,  15. Band, 3.

   Heft, enthalten.  



  Die Zeichnung zeigt ein Ausführungs  beispiel der Erfindung. Für die     Phasen-          kompensierung    des Induktionsmotors 1 ist  
EMI0001.0003     
  
       vorgesehen. 3 ist die Antriebsmaschine für  die Kommutatorhintermaschine. Die Hinter  maschine ist nun im Ständer mit einer  Phasenwicklung 4 ausgerüstet. In dem  Stromkreis der Phasenwicklung liegt zur  Abgleichung des induktiven und des Ohm  schen Widerstandes ein einstellbarer     Ohm-          scher    Widerstand 5. Diese Anordnung hat  die Eigenschaft, dass die Kommutatorhinter  maschine sieh selbst erregt, so dass also eine  Phasenkompensierung auch bei Leerlauf des  Aggregates eintritt.

   Der in die Wicklung 4  eingeschaltete Regulierwiderstand 5 dient vor  allem dazu, das richtige Verhältnis des  Ohmschen zum induktiven Widerstand der  Wicklung 4 herzustellen, um die Selbst  erregung auf den gewünschten Wert zu  bringen.  



  Statt die Hintermaschine im Ständer mit  einer Phasenwicklung für die Selbsterregung  auszurüsten, kann man auch eine     Kurz-          sehlussivieklung    verwenden, wenn nur der  Ohmsche und der induktive Widerstand die  ser Kurzschlusswicklung in dem für die    Selbsterregung erforderlichen Verhältnis  stehen.



  Multi-phase commutator machine with a winding housed in the stator and powered by induction from the armature.
EMI0001.0000
  
       Induction-fed winding (cage or phase winding) must be balanced against each other in such a way that self-excitation occurs. As the tests have shown, self-excitation can be achieved in any case by correctly dimensioning the ohmic resistance of the stator winding. The mathematical information, from which it goes, how the required ratio between the ohmic and the inductive resistance for the purpose of self-excitation of the commutator rear machine can be produced in each case, are in the article by Brüderlin: "Three-phase exciter as an independent generator of vibrations of low frequency" in the magazine, Archiv für Elektrotechnik ", year 1925, volume 15, 3.

   Booklet included.



  The drawing shows an embodiment of the invention. For the phase compensation of the induction motor 1 is
EMI0001.0003
  
       intended. 3 is the prime mover for the commutator back machine. The rear machine is now equipped with a phase winding 4 in the stator. In the circuit of the phase winding there is an adjustable ohmic resistance 5 to balance the inductive and ohmic resistance.

   The regulating resistor 5 switched into the winding 4 is used primarily to produce the correct ratio of the ohmic to the inductive resistance of the winding 4 in order to bring the self-excitation to the desired value.



  Instead of equipping the rear machine in the stator with a phase winding for self-excitation, one can also use a short-circuit if only the ohmic and inductive resistance of this short-circuit winding are in the ratio required for self-excitation.
