Description

  

  Selbstkühlender Käfiganker für Induktionsmotoren.    Gegenstand der Erfindung ist ein neu  artiger Käfiganker für Induktionsmotoren, der  mit Ventilationsflügeln versehen ist. Darnach  werden die Stäbe selbst, und zwar min  destens teilweise, über den Kurzschlussring  der betreffenden Läuferseite hinaus verlän  gert und abgeflacht,. so dass die verlänger  ten flachen Stabenden als Ventilationsflügel  wirken.  



  In welcher Weise die Erfindung beispiels  weise ausgeführt werden kann, ist aus der  Zeichnung ersichtlich. Der stabförmige Leiter  a ist kurz nach seinem Austritt aus dem  Läufereisen b an den innerhalb des     Stab-          käfiges    angeordneten Kurzschlussring c ange  lötet und über diesen hinaus verlängert. Der  verlängerte Teil d ist abgeplattet und bildet  dadurch einen Ventilatorflügel.  



  Für höhere Drehzahlen kann zur Auf  nahme der Fliehkraft vorne ein Tragring e,  eine Bandage f oder ein Schlussring g ange  bracht werden. Man kann die Stäbe beid  seitig oder nur einseitig verlängern oder auch    abwechselnd einen Stab nach links, den an  dern nach rechts verlängern.



  Self-cooling cage armature for induction motors. The invention relates to a new type of cage armature for induction motors which is provided with ventilation blades. Then the bars themselves, at least partially, are lengthened and flattened beyond the short-circuit ring of the rotor side in question. so that the extended flat rod ends act as ventilation blades.



  The way in which the invention can be carried out, for example, can be seen from the drawing. Shortly after it emerges from the armature b, the rod-shaped conductor a is soldered to the short-circuit ring c arranged within the rod cage and is extended beyond it. The extended part d is flattened and thus forms a fan blade.



  For higher speeds, a support ring e, a bandage f or a locking ring g can be attached to the front to absorb the centrifugal force. You can extend the bars on both sides or only on one side or alternately extend one bar to the left and the other to the right.
