Abstract:
Electrical rotating machine comprising a rotor and a stator, at least one of the rotor and the stator comprising bundles of laminations positioned by way of a carrying element (rotor hub 3 or stator housing), anda non-rotatable connection between the carrying element and the bundle of laminations by a form-locking contact of the carrying element on the bundle of laminations which is caused by plastic deformation, wherein the bundle of laminations has a profiled contact surface for the carrying element (rotor hub 3), wherein formn-locking contact is achieved on the profiled contact surface of the bundle of laminations by an electromagnetic forming of the carrying element (the rotor hub 3 or the stator housing) effective at least in certain areas, wherein the rotor has a bundle of laminations with longitudinal grooves. wherein a contact surface for the rotor hub has a wave profile, and wherein a surface-enlarling wave crest is radially aligned with each longitudinal groove.
