  Polanordnung für elektrische Maschinen mit   runden Polkernen.   



   Bei elektrischen Maschinen mit ausgeprägten Polen bereitet die Unterbringung der Erregerwicklung grosse Schwierigkeiten, wenn die Maschinen einen kleinen Durchmesser erhalten sollen. Diese Schwierigkeiten werden für Maschinen mit runden Polkernen nach der Erfindung dadurch vermieden, dass benachbarte   Polkerne   in einander entgegengesetzter Richtung gegen ihre Polschuhe, u. zw. in Richtung der   Maschinenaehse   versetzt werden. 



   In der Zeichnung ist als Ausführungsbeispiel ein Polrad mit Rundpolen dargestellt. Darin ist 1 der Polradkörper, in dem die runden Polkerne 2 mit den   Polsehuhen   3 aufgesetzt sind. 4 sind die auf den Polkernen aufgebrachten Wicklungen. 



   Nach der Erfindung sind die Polkerne 2 gegen die   Polschuhe   3 in Richtung der Maschinenaehse verschoben, u. zw. so, dass benachbarte   Polkerne   in einander entgegengesetzter Richtung versetzt sind. 



   Gegenüber den bekannten Polanordnungen, bei denen die Pole in der Mitte des Polschuhes angeordnet sind, wird hiedurch Wickelraum zwischen den Polen gewonnen. Die Polsehenkel können jetzt verkürzt werden, wodurch der Durchmesser des Polrades und damit die Grösse der ganzen Maschine verringert wird. 



   Weitere Vorteile ergeben sich daraus, dass die   Polwiellungen über   das Jocheisen hinausragen. 



  Einmal werden   hiedureh   die Polwicklungen besser   gekühlt,   zum ändern wird die Bewegung der Kühlluft für die   Ständerwickelköpfe   gefördert. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Pole arrangement for electrical machines with round pole cores.



   In electrical machines with pronounced poles, it is very difficult to accommodate the field winding if the machines are to have a small diameter. These difficulties are avoided for machines with round pole cores according to the invention that adjacent pole cores in opposite directions against their pole pieces, u. be offset in the direction of the machine axis.



   In the drawing, a pole wheel with round poles is shown as an exemplary embodiment. 1 is the pole wheel body in which the round pole cores 2 with the pole shoes 3 are placed. 4 are the windings applied to the pole cores.



   According to the invention, the pole cores 2 are shifted against the pole shoes 3 in the direction of the machine axis, u. betw. so that neighboring pole cores are offset in opposite directions.



   Compared to the known pole arrangements, in which the poles are arranged in the middle of the pole piece, winding space is gained between the poles. The pole arm can now be shortened, which reduces the diameter of the pole wheel and thus the size of the entire machine.



   Further advantages result from the fact that the pole lungs protrude beyond the yoke iron.



  On the one hand, the pole windings are cooled better, on the other hand, the movement of the cooling air for the stator winding heads is promoted.
