Abstract

Ein Kurzschlussrotor (1) besitzt ein Rotorpaket (2), in demgeschrägte oder achsparallele Nuten (4), in die Kupferstäbe (3)eingesetzt sind, vorgesehen sind. An die Kupferstäbe (3) sindStreusegmentstege (5) angeformt, die zur Außenfläche (7) desRotorpaketes (2) ragen. Die Kupferstäbe (3) sind gegenüber denInnenflächen (9) der Nuten (4) isoliert und an diesen überachsparallele Rippen (8) abgestützt. Die über die seitlichenStirnflächen (12) des Rotorpaketes (2) vorstehenden Enden derKupferstäbe (3), die abwechselnd Kerben (11) aufweisen, sind aufbeiden Seiten des Rotorpaketes (2) mit angegossenenKurzschlussringen (20) aus Aluminium elektrisch leitendverbunden. In einzelnen Nuten (4) sind aus dem WerkstoffAluminium der Kurzschlussringe (20) bestehende und mit denKurzschlussringen (20) einstückig ausgebildete Stäbe (15)vorgesehen. Die Aluminiumstäbe (15) sind mit gleichenWinkelabständen, insbesondere 90°, voneinander angeordnet.A short-circuit rotor (1) has a rotor core (2) in which are provided slanted or axially parallel grooves (4) in which copper rods (3) are inserted. To the copper rods (3) are formed Trussegmentstege (5), which protrude to the outer surface (7) of the rotor assembly (2). The copper rods (3) are insulated from the inner surfaces (9) of the grooves (4) and supported on these over-axis-parallel ribs (8). The ends of the copper rods (3) projecting beyond the lateral end faces (12) of the rotor core (2) and alternately having notches (11) are electrically conductively connected on both sides of the rotor core (2) to aluminum sheathed short rings (20). In individual grooves (4) made of the material aluminum of the short-circuit rings (20) and with the short-circuiting rings (20) integrally formed rods (15) are provided. The aluminum rods (15) are arranged at equal angular intervals, in particular 90 °, from each other.
