Abstract

Ein Kurzschlussrotor (1) besitzt ein Rotorpaket (2), in dem geschrägte oder achsparallele Nuten (4), in die Kupferstäbe (3) eingesetzt sind, vorgesehen sind. An die Kupferstäbe (3) sind Streusegmentstege (5) angeformt, die zur Außenfläche (7) des Rotorpaketes (2) ragen. Die Kupferstäbe (3) sind gegenüber den Innenflächen (9) der Nuten (4) isoliert und an diesen über achsparallele Rippen (8) abgestützt. Die über die seitlichen Stirnflächen (12) des Rotorpaketes (2) vorstehenden Enden der Kupferstäbe (3), die Kerben (11) aufweisen, sind auf beiden Seiten des Rotorpaketes (2) mit angegossenen Kurzschlussringen (20) aus Aluminium elektrisch leitend verbunden. In einzelnen Nuten (4) sind aus dem Werkstoff Aluminium der Kurzschlussringe (20) bestehende und mit den Kurzschlussringen (20) einstückig ausgebildete Stäbe (15) vorgesehen. Die Aluminiumstäbe (15) sind mit gleichen Winkelabständen, 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) stray segment webs (5) are formed, which protrude to the outer surface (7) of the rotor core (2). The copper rods (3) are insulated from the inner surfaces (9) of the grooves (4) and supported on these over axially parallel ribs (8). The ends of the copper rods (3) projecting beyond the lateral end faces (12) of the rotor core (2) and having notches (11) are electrically conductively connected on both sides of the rotor core (2) with cast aluminum short-circuiting rings (20). In individual grooves (4) of the material of the aluminum shorting rings (20) existing and with the short circuit rings (20) integrally formed rods (15) are provided. The aluminum rods (15) are arranged at equal angular intervals, in particular 90 °, from each other.
