Description
In dem Hauptpatent 525 723 ist ein Doppelkäfiganker beschrieben, bei dem die für den Anlauf dienende obere Käfigwicklung isoliert ist. Eine gute, einfache, billige und doch ausreichende Isolation wird erfindungsgemäß dadurch erreicht, daß die oberen Stäbe mit einer Oxydschicht überzogen werden. Besonders zweckmäßig ist es, die Oxydschicht nicht unmittelbar auf die oberen Stäbe aufzubringen, sondern vorher die Stäbe mit einer die Oxydation fördernden Schicht, z. B. Aluminium, zu überziehen, die dann mit der Oxydschicht überzogen wird.In the main patent 525 723 a double cage anchor is described in which the for Starting serving upper cage winding is isolated. A good, simple, cheap and yet sufficient one According to the invention, insulation is achieved in that the upper rods are covered with an oxide layer be coated. It is particularly useful not to direct the oxide layer to apply to the upper rods, but before the rods with an oxidation promoting Layer, e.g. B. aluminum, to be coated, which is then coated with the oxide layer.
