 auch die in Fig. 4 dargestellte Form geben und mit einer Wicklung w versehen, die mit der Wicklung der Wendepole in Reihe geschaltet ist. 



   Bei einem Anker mit   Wellenwicklung   liegen die durch die Bürsten kurzgeschlossenen und in Reihe geschalteten Spulen unter verschiedenen Polen, man kann daher mehrere aufeinanderfolgende Wendepole weglassen und z. B. einen   zwölfpoligen Anker   mit dreifacher Reihenschaltung z. B. mit nur drei bis sechs Wendepolen ausführen. 



   Bei einer einfachen Reihenschaltung sind p kurzgeschlossene Spulen hintereinandergeschaltet, worin p die Anzahl der Polpaare bedeutet ; man kann in diesem Fall sämtliche Wendepole fortlassen bis auf einen und diesen so stark erregen, dass er in einer   Sputensoite   die kom-   mutin'rende   elektromotorische Kraft für die p hintereinandergeschalteten Suplen induziert,
Das Weglassen von   Wendepolcn     oder Wendespulen   ist auch bei anderen Anordnungen, z.   B.   derjenigen von Swinburne, der einen Hufeisenmagnet zwischen je zwei Hauptpolen anordnet, möglich. 



   Die Anordnung ist sowohl für Gleichstrommaschinen als für   Wechselstrommaschinen mit     Kommutator   verwendbar. So werden z. B. bekanntlich bei den einphasigen Wechselstrom-   seriemotoren   ebenfalls Wendepole angeordnet, die auf verschiedene Art erregt werden   können.

   Ersparnis an Kupfer   für die Wendepole.   



   Fortfall einer Anzahl Wendepole und dadurch verbesserte Ventilation der Maschine. 



     Verminderte Reaktanz   der kurzgeschlossenen Spulen, weil nicht alle Spulenseiten derselben   sich vor dem Eisen der Wendepole befinden.   



   Kleinere   magnetische Streuung   der Wendepole, weil weniger Pole vorhanden sind.

 also give the shape shown in Fig. 4 and provided with a winding w which is connected in series with the winding of the reversing poles.



   In the case of an armature with a wave winding, the coils short-circuited by the brushes and connected in series are at different poles. Therefore, several consecutive reversing poles can be omitted and B. a twelve-pole armature with triple series connection z. B. run with only three to six reversing poles.



   In a simple series connection, p short-circuited coils are connected in series, where p means the number of pole pairs; In this case, one can omit all reversing poles except for one and excite this so strongly that it induces the commutating electromotive force for the p series-connected suplen in a sputensoite
The omission of Wendepolcn or reversing coils is also in other arrangements, such. B. that of Swinburne, who arranges a horseshoe magnet between two main poles, possible.



   The arrangement can be used both for DC machines and for AC machines with a commutator. So z. B. As is well known, reversing poles are also arranged in the single-phase AC series motors, which can be excited in various ways.
 EMI2.2
 



   Savings on copper for the reversing poles.



   Elimination of a number of reversing poles and thus improved ventilation of the machine.



     Reduced reactance of the short-circuited coils because not all coil sides of the same are in front of the iron of the reversing poles.



   Smaller magnetic dispersion of the reversing poles because fewer poles are available.
