Description

Verschränkter Leiter für elektrische Maschinen mit großer Nutenstreuung. In der Patentschrift 259879 ist ein Leiter für elektrische Maschinen mit großer Nutenstreuung beschrieben, der aus mehreren übereinanderliegenden parallelgeschalteten Flachdrähten besteht: Die Flachdrähte sind in der Mitte der Nut so gegeneinander verschränkt, daß sie dort in zwei Gruppen mit ihren Schmalseiten aneinanderstoßen. Das- vom Leiterstrom erzeugte Nutenquerfeld erreicht seinen größten Betrag am Ankerumfang und ruft dort die größten Verluste pro Zentimeter Nutenhöhe hervor. Gemäß der Erfindung werden daher die äußersten Flachdrähte eines solchen Leiters, die teils vor, teils hinter der Verschränkung dem Ankerumfang zunächst liegen, nochmals parallel ihren Flachseiten in einige Schichten gespalten; die Schichten werden elektrisch parallel .geschaltet und bei der Verschränkung als Ganzes behandelt. Durch die dabei erfolgende Verdrehung jedes gespaltenen Flachdrahtquerschnittes um i8o° wird die Aufeinanderfolge der den Flachseiten parallelen Schichten vertauscht. In jeder durch die Mittellinien zweier Schichten eines Flachdrahtes gebildeten Schleife heben sich die durch das Nutenquerfeld erzeugten EMKe ebenso auf wie in einer durch zwei ungeteilte Flachdrähte gebildeten Schleife.Crossed conductor for electrical machines with a large number of slots. Patent specification 259879 describes a conductor for electrical machines with a wide range of slots, which consists of several superimposed parallel-connected flat wires: The flat wires are interlaced in the middle of the slot so that their narrow sides abut in two groups. The groove transverse field generated by the conductor current reaches its greatest amount at the armature circumference and causes the greatest losses per centimeter of groove height there. According to the invention, the outermost flat wires of such a conductor, which are partly in front of, partly behind the entanglement of the anchor circumference, are again split parallel to their flat sides into several layers; the layers are electrically connected in parallel and treated as a whole when they are entangled. As a result of the twisting of each split flat wire cross-section by 180 °, the sequence of the layers parallel to the flat sides is reversed. In each loop formed by the center lines of two layers of a flat wire, the EMFs generated by the groove transverse field cancel each other out just as in a loop formed by two undivided flat wires.

Abb. i zeigt einen in zwei Schichten gespaltenen Leiter. Infolge der Verschränkung des Leiters bietet jeder Flachdraht an der Verschränkungstelle, dem Nutenquerfeld, eine bedeutend größere Oberfläche, doch lassen sich die zusätzlichen Verluste an diesen Stellen verringern, wenn die gespaltenen Flachdrähte in ihrem verschränkten Teile einen oder mehrere Einschnitte längs der Faserrichtung, parallel zu den Schmalseiten, erhalten. Auch bei massiven Leitern läßt sich, wie Abb. 2 zeigt, dieses Mittel anwenden.Fig. I shows a conductor split into two layers. As a result of Every flat wire offers entanglement of the conductor at the entanglement point, the Groove transverse field, a significantly larger surface, but the additional Losses at these points decrease when the split flat wires are in their entangled parts one or more incisions along the grain direction, parallel to the narrow sides. Even with solid ladders, as Fig. 2 shows, apply this remedy.
