Abstract

A rotor for an electrical machine includes a laminated core with stack of sheets extending in an axial direction from a first axial end to a second axial end. The stack of sheets has layered layers in the axial direction. Each layer has a plurality of sheet areas with flow conduction blocks situated between adjacent sheet areas. At least one flow conduction block is cast with a non-ferromagnetic potting compound. The potting compound extends in the at least one flow conduction block from the first axial end to the second axial end. Fastened sheet areas, respectively, having at least one web protrudes into the potting compound. The protruding web, at least in part, extends in a direction, having a component in the axial direction. In each layer, at least one sheet area is a fastened sheet area.
