Abstract

A rotor for an electrical machine includes a rotor carrier of metallic material with a back wall extending radially to the axis of rotation of the electrical machine and a tubular section extending in the axial direction, in which a laminated core is installed. The rotor carrier is designed as a single, flow-formed part with axially extending ribs which engage in grooves on the laminated core.
