Description

  

  Drehfeld-Asynchronmotor rmit genutetem Kurzschlussanker und in der Höhe  unterteilten Ankerleitern.    Die Erfindung bezieht sich auf einen  Drehfeld-Asynchronmotor mit genutetem  Kurzschlussanker und in der Höhe unter  teilten Ankerleitern, deren Widerstand bei  grossen Schlüpfungen durch die Wirkung  der Stromverdrängung vermehrt wird. Er  findungsgemäss soll durch ein besonderes  Mittel die Wirkung der Nutenstreuung auf  die Stromverdrängung der Leiter vergrössert  werden, nämlich durch in die Ankerleiter  eingelagerte magnetische Schichten.  



  Die magnetischen Schichten können so  wohl zwischen den einzelnen Teilleitern des  unterteilten Ankerleiters liegen, als in die  Teilleiter eingebettet sein.  



  Die Zeichnung betrifft zwei Ausführungs  beispiele der Erfindung.  



  Fig. 1 zeigt einen Ankerleiter im Quer  schnitt mit den Nutenumrissen, Fig. 2 einen  Käfiganker im Längsschnitt; Fig. 3 ist  ein Querschnitt nach der Linie x-x in  Fig. 2.    Der in Fig. 1 dargestellte Ankerleiter  besteht aus sechs kupfernen Teilleitern k  und fünf dazwischen gelagerten Eisenstäben  e. Die sechs Teilleiter k sind hierbei von  den Eisenstäben e isoliert und durch die  Stirnverbindungen in Reihe geschaltet zu  denken.  



  Bei dem Käfiganker nach Fig. 2 dagegen  liegen die Eiseneinlagen in den Teilleitern.  Hier liegen in jeder Nut zwei parallel ge  schaltete Teilleiter a, b übereinander, die  in der Mitte verschränkt sind, so dass der  in der einen Hälfte seiner Länge unten  liegende Teilleiter in der zweiten Hälfte  oben liegt, und umgekehrt, und die Span  nungen beider Teilleiter einander stets genau  gleich sind. Jeder Teilleiter besteht aus zwei  übereinander liegenden Kupferstäben k und  einer eisernen Zwischenlage e (Fig. 3). An  den Enden sind die Teilleiter unter sich und  mit den Kurzschlussringen r leitend ver  bunden. Die Eisenstäbe e können zur Strom-      leitung mitbenutzt werden, was natürlich  zweckmässig ist.  



  Statt die mit Eiseneinlagen versebenen  Kupferstäbe gemäss Fig. 2 miteinander zu  verschränken, kann man sie auch miteinander  verseilen.  



  Trotz der vergrösserten Nutenstreuung  ist die totale Streuung des Ankers nach  Fig. 2 durchaus erträglich, indem die Stirn  streuung eines Käfigankers wegen des Fort  falles von weit ausladenden Stirnverbindun  gen gering bleibt.



  Rotary field asynchronous motor with grooved short-circuit armature and armature ladders divided in height. The invention relates to a rotating field asynchronous motor with a grooved short-circuit armature and armature conductors that are divided in height, the resistance of which is increased by the effect of the current displacement in the case of large slippage. According to the invention, the effect of the slot scattering on the current displacement of the conductor is to be increased by a special means, namely by magnetic layers embedded in the armature conductor.



  The magnetic layers can lie between the individual subconductors of the subdivided armature conductor as well as be embedded in the subconductors.



  The drawing relates to two execution examples of the invention.



  Fig. 1 shows an anchor conductor in cross section with the groove outlines, Fig. 2 shows a cage anchor in longitudinal section; Fig. 3 is a cross section along the line x-x in Fig. 2. The armature conductor shown in Fig. 1 consists of six copper partial conductors k and five iron rods e between them. The six sub-conductors k are insulated from the iron bars e and connected in series through the end connections.



  In the case of the cage anchor according to FIG. 2, on the other hand, the iron inserts are located in the sub-conductors. Here, two parallel sub-conductors a, b lie one above the other in each slot, which are interlaced in the middle, so that the sub-conductor lying at the bottom in one half of its length is on top in the second half, and vice versa, and the voltages of both sub-conductors are always exactly the same. Each sub-conductor consists of two copper bars k lying on top of one another and an iron intermediate layer e (Fig. 3). At the ends, the sub-conductors are conductively connected to each other and to the short-circuit rings r. The iron bars e can also be used to conduct electricity, which is of course useful.



  Instead of interlacing the copper rods with iron inlays according to FIG. 2, they can also be stranded together.



  Despite the increased distribution of the grooves, the total distribution of the anchor according to FIG. 2 is quite tolerable, in that the forehead scatter of a cage anchor remains low because of the case of sweeping frontal connections.
