Abstract
A rotor () with a rotation axis () is provided for an electric drive machine (). The rotor () has a plurality of rotor assemblies (), each of which has a plurality of laminated cores () and a number of magnets () corresponding to a pole pair arrangement (). The rotor also has a rotor shaft () on which the rotor assemblies () are fixed. The rotor assemblies () are positioned on the rotor shaft () such that they are rectified in accordance with their axial runout (), while taking into account the pole pair arrangement (). The rotor can reduce a thermally induced change in imbalance.
