EMI1.1
Es ist bekannt, boi Spulen für elektrische Maschinen und Apparate dadurch günstige Abkuhlungsverhältnisse zu erreichen, dass man die Spulen aus blankem Flachkupfer wickelt und nur zwischen den einzelnen Lagen isoliert. Dabei kommt aber nur der vergleichsweise schmale Rücken jeder Windung zur unmittelbaren Abgabe der Wärme an die umgebende Luft in Betracht.
Man hat vorgeschlagen, die Abkühlung dadurch zu verbessern, dass einzelne Windungen der Spulen breiter ausgeführt werden als die übrigen, derart, dass sie über diese seitlich weit hervorragen. Man ist aber dann genötigt, für dieselbe Spule zwei verschiedene Leiterprofile zu verwenden.
Nach vorliegender Erfindung kann man auch bei Verwendung eines einzigen Profiles eine erheblich vergrösserte Abküh1ungsfläche dadurch erreichen, dass man das Flachkupfer an einzelnen Stellen mit vergrössertem Wicklungsradius wickelt. Hierdurch wird die betreffende Windung seitlich zwischen den benachbarten Windungen vorgerückt und bietet durch ihre freiliegenden Flächen die Möglichkeit besserer Abkühlung.
Die Fig. 1 und 2 der Zeichnung zeigen z. B. eine solche Spule für einen Polkern mit länglichem Querschnitt.

EMI1.1
It is known to use coils for electrical machines and apparatus to achieve favorable cooling conditions by winding the coils from bare flat copper and only isolating them between the individual layers. However, only the comparatively narrow back of each turn comes into consideration for the direct transfer of heat to the surrounding air.
It has been proposed to improve the cooling by making individual turns of the coils wider than the others, in such a way that they protrude far laterally over them. But then you have to use two different conductor profiles for the same coil.
According to the present invention, even when using a single profile, a considerably enlarged cooling surface can be achieved by winding the flat copper at individual points with an enlarged winding radius. As a result, the turn in question is advanced laterally between the adjacent turns and offers the possibility of better cooling due to its exposed surfaces.
Figs. 1 and 2 of the drawing show, for. B. such a coil for a pole core with an elongated cross section.
