Zur Verbindung der Wicklung sind dann Schleifringe und Bürsten zu Hilfe zu nehmen. 



   Ausser der einfacheren und voneinander abhängigen Herstellung der beiden Wicklungen hat die kleine   Phasen zahl   der Läuferwicklung bzw. die grössere Lamellonzahl der Gleichstromwicklung noch den Vorzug, dass die Abteilungen oder Spulen    der Läuferwicklung   nicht durch die   Dürsten direkt   kurzgeschlossen werden.

 EMI2.1
 It is absolutely necessary that the rotor of the asynchronous machine and the armature of the direct current machine sit on the same shaft, but the asynchronous machine and the direct current machine can be designed as independent machines and be coupled firmly or elastically in some way. To connect the winding, slip rings and brushes are then used.



   In addition to the simpler and interdependent production of the two windings, the small number of phases in the rotor winding or the greater number of lamellons in the direct current winding has the advantage that the sections or coils of the rotor winding are not directly short-circuited by the thirst.

   It should also be noted that the waveform of the electro-

     The improvements mentioned are so significant for the manufacture and the mode of operation of the converter that it cannot be carried out successfully in practice without these improvements.



   The machine unit can be used both for converting single-phase or Mohr-phase electricity into direct current and for converting direct current into single-phase or multiphase electricity. The unit can also be used as an AC motor, u. between you have two

PATENT. ANSPRUCH : Wechselstrommaschine, bestehend aus einer asynchronen Maschine mit mehrphasiger Läuferwicklung und einer Gleichstrommaschine, wobei die Läuferwicklung der asynchronen Maschine ebenso wie die Ankerwicklung der Gleichstrommaschine in Abteilungen geteilt ist, welch letztere parallel zu den Abteilungen des Gleichstromankers mit den Stromwenderstegon desselben derart verbunden sind, dass die parallel geschalteten Abteilungen der beiden Wicklungen zu einer durch die Achse dos Maschinenaggrogats gehenden Ebene symmetrisch liegen, dadurch gekennzeichnet, dass die Zahl der Stromwenderlamellen der Gleichstrommaschine grösser ist als die Zahl der Phasen der Läuferwicklung der asynchronen Maschine. PATENT. CLAIM : AC machine, consisting of an asynchronous machine with polyphase rotor winding and a DC machine, the rotor winding of the asynchronous machine as well as the armature winding of the DC machine being divided into sections, the latter being connected in parallel to the sections of the DC armature with the commutator bars of the same in such a way that the parallel connected departments of the two windings are symmetrical about a plane going through the axis dos machine aggregates, characterized in that the number of commutator lamellas of the DC machine is greater than the number of phases of the rotor winding of the asynchronous machine.
