KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es ist bekannt, die Leiter elektrischer Maschinen aus parallelgeschalteten, gegeneinander isolierten und verdrillten Stäben oder Drähten herzustellen, um die von der einseitigen Strom-Verdrängung in den Nuten herrührenden zusätzlichen Kupferverluste zu verringern. Die Verdrillung kann in bekannter Weise im Innern der Nut oder in den Stirnverbindungen liegen.It is known that the conductors of electrical machines from parallel-connected, against each other to produce isolated and twisted rods or wires in order to avoid the one-sided current displacement to reduce additional copper losses originating in the grooves. the Twisting can be done in a known manner in the interior of the groove or in the end connections lie.
ίο Das Charakteristische der Verschränkung ist eine solche Leiterführung, daß die Summe der von irgendeiner, möglichen Strombahn umschlossenen Nutkraftlinien (Σ N) ein Minimum wird. Bei der gewöhnlichen Verschränkung, bei der der oberste Stab der einen Nut zum untersten Stab der nächsten, der zweite Stab zum zweituntersten Stab der nächsten Nut wird usf. (vgl. Fig. 1), wird die Forderung Σ (N) = Minimum im allgemeinen deshalb nicht erfüllt, weil das Nutenfeld mit der Entfernung vom Nutengrund wächst (vgl. Fig. 2).ίο The characteristic of the entanglement is such a conductor routing that the sum of the slot force lines enclosed by any possible current path (Σ N) becomes a minimum. In the usual entanglement, in which the top bar of one groove becomes the bottom bar of the next, the second bar becomes the second bar from the next groove, and so on (see Fig. 1), the requirement Σ (N) = minimum in general therefore not fulfilled because the slot field grows with the distance from the slot base (see. Fig. 2).
Bei nur zwei parallelen Drähten (vgl. Fig. 3) ist ohne weiteres zu erreichen, daß Σ (N) — ο wird. Ebenso entspricht die gewöhnliche Verschränkung bei drei Stäben (Fig. 4), bei der Ober litze und Unterlitze nach jeder halben Windung verschränkt sind und die Mittellitze glatt durchgeführt wird, mit für den praktischen Betrieb genügender Annäherung der genannten Forderung Σ (N) = Minimum.With only two parallel wires (see. Fig. 3) can easily be achieved that Σ (N) - ο. Likewise, the usual entanglement of three rods (Fig. 4), in which the top strand and bottom strand are interlaced after every half turn and the middle strand is carried out smoothly, with a sufficient approximation of the stated requirement Σ (N) = minimum for practical operation.
Gemäß der Erfindung wird eine größere Anzahl von parallelen Leitern in der Weise verschränkt, daß je zwei bzw. drei Leiter unter sich und die hieraus gebildeten Leitergruppen gegeneinander verschränkt werden. Fig. 5 zeigt die neue Art der Verschränkung für vier Leiter, Fig. 6 für sechs Leiter. In gleicher Weise lassen sich alle praktisch vorkommenden Anzahlen von Leitern parallel schalten ohne nennenswerte Wirbelstrombildung.According to the invention, a larger number of parallel conductors are interlaced in such a way that that two or three leaders among themselves and the leader groups formed from them are entangled against each other. Fig. 5 shows the new type of entanglement for four Ladder, Fig. 6 for six conductors. In the same way, all practically occurring Connect numbers of conductors in parallel without significant eddy currents.
Diese Verschränkung höherer Ordnung kann nur dann in der gleichen Lochspule erfolgen, wenn zwei oder mehr Leiter nebeneinander in der Nut liegen, andernfalls muß sie beim Übergang von einer Lochspule in die andere oder von einer Spule in die andere erfolgen.This higher order entanglement can only take place in the same perforated coil if two or more conductors are next to each other in the groove, otherwise it must be at Transition from one perforated coil to the other or from one coil to the other take place.
Es sei noch darauf hingewiesen, daß beispielsweise bei zwei parallelen Litzen nur eine Verschränkung pro Phase erforderlich ist, wenn die Parallelschaltung nur an dem Phasenanfang und -ende erfolgt. Ähnliches gilt bei drei-, vier- und sechsfacher Parallelschaltung.It should be noted that, for example, with two parallel strands only one Entanglement per phase is required if the parallel connection is only at the beginning of the phase and end takes place. The same applies to three, four and six-fold parallel connections.
