The invention relates to a method for producing a beveled cage rotor (1) for an asynchronous machine (2) and to a cage rotor (1) that can be produced by means of such a method. In order to improve the efficiency of the asynchronous machine (2), the cage rotor (1) comprises a laminated rotor core (5) having grooves (4), short-circuit rings (6) made of a first material and case onto the end face of the laminated rotor core (5), and short-circuit bars (3; 11; 12) made of a second material having a higher specific electrical conductivity than the first material and disposed in the grooves (4), wherein the laminated rotor core (5) and the short-circuit bars (3; 11; 12) comprise a bevel and nearly completely fill in an inner groove region (7) as seen in the radial direction of the laminated rotor core (5). |
