Rotor and process for producing the same

摘要

The invention relates to a rotor that exhibits a rotor shaft, by which a rotor axis is defined, and also a core stack that is arranged around the rotor shaft along a longitudinal portion of the rotor axis. Along the longitudinal portion the rotor shaft exhibits a first surface region, the shape of which describes a circular cylinder, and also a second surface region which is constituted by structural elements that with respect to the rotor axis rise radially outwardly above the first surface region. For the purpose of producing the rotor, the core stack can be pushed over the rotor shaft and in the process can be pushed against the structural elements) in such a manner that it is deformed and by this means a positive connection between the rotor shaft and the core stack is generated. In this way, in particularly simple manner in terms of production engineering a reliable and torsion-proof connection between the core stack and the rotor shaft can be formed.
