   Die vorliegende Erfindung bezieht sich auf eine Einrichtung zur Kühlung der Magnetwicklungen bei solchen Feldmagneten, bei welchen die Wicklungen auf einem zweckmässig zylinderischen Kern, der an beiden Enden Polschuhe trägt, gewickelt sind. 



   Einer der grössten   Übelstände   bei derartigen Feldmagneten ist die Schwierigkeit, die Feldwicklungen in wirksamer Weise zu kühlen und hat diese Schwierigkeit dazu beigetragen, dass

   Durch diese Einrichtung werden zwei Vorteile gewonnen.
Teils kann man die der Kühlluft ausgesetzte Oberfläche der Wicklungen durch Vermehrung der Anzahl von Gruppen beliebig gross machen, teils können die Wicklungen aus bandförmigen Leitern, die spiralförmig von innen nach aussen gewickelt werden, bestehen.

 EMI1.1
 



   The present invention relates to a device for cooling the magnet windings in such field magnets in which the windings are wound on an expediently cylindrical core which has pole shoes at both ends.



   One of the greatest drawbacks with such field magnets is the difficulty in cooling the field windings in an effective manner and this difficulty has contributed to that

   Two advantages are gained by this facility.
In part, the surface of the windings exposed to the cooling air can be made as large as desired by increasing the number of groups; in part, the windings can consist of strip-shaped conductors that are wound in a spiral from the inside out.



   The edges of the windings facing the intermediate spaces are expediently not insulated. The edges can also be provided with tines or the like to the surface

   They are also cut off at an angle or provided with prongs or the like in order to enlarge the upper part and thereby increase the cooling effect.



   The outermost winding groups will be. as can be seen in the drawing, supported by the protruding edges of the pouches, while the middle group is exposed to the centrifugal tensions of the same magnitude, which act in opposite directions. is exposed and
