摘要： A rotor for an electric machine includes a laminated core and a groove which extend in axial direction from a first axial end to a second axial end along a rotation axis. The groove has a groove filling having a first material with a metal element of the periodic table. The groove filling has a cast metal region, which extends with an end region at the first axial end at least partially over the laminated core. The cast metal region extends through the groove from the first axial end to the second axial end, and fills up a first part of the groove with a first material. An insert fills up a second part of the groove with a second material which has the metal element of the periodic table. The insert part and the cast metal region are connected in a bonded manner by a connection zone.
