The invention relates to a method for producing a cage rotor for an asynchronous machine, comprising the steps of: providing a rotor body (2) having a conductor bar segment (10) in which a plurality of conductor bars (11) are provided; producing conductor bar slots (12) in the conductor bar segment (10), wherein one of the conductor bar slots (12) is provided for each of the conductor bars (11), and producing short circuit ring recesses (6, 7) for short circuit rings (4, 5), wherein the conductor bar slots (12) each open into the short circuit ring recesses (6, 7); pressure die casting cage material in the conductor bar slots (12) in situ, so that the conductor bars (10) are formed of the conductor bar material in the conductor bar slots (12) and the short circuit rings (4, 5) are formed in the short circuit ring recesses (6, 7); and generating an area in the conductor bar material and the rotor body material comprising a metallurgical bond between the conductor bar material and the rotor body material at interfaces between the conductor bars (10) and the rotor body (2), wherein the metallurgical bond is formed such that the conductor bars (10) can be retained in the conductor bar slots (12) at the interfaces when operating the cage rotor (1), and the short circuit rings (4, 5) can be retained in the short circuit ring recesses (6, 7). |
