Abstract

In a method for producing a rotor of an asynchronous electric machine, a carrier shaft is produced with shaft slots and a squirrel cage rotor is applied to the carrier shaft. The carrier shaft and an electrically conductive bulk material of nickeled copper is placed into a container so that the bulk material fills up the shaft slots. The bulk material is compacted in the container by hot isostatic pressing and thereby bonded to the carrier shaft such that nickel as diffusion material causes permanently bonding of copper to the carrier shaft. The container is then detached from the carrier shaft.
