Zusammenfassung:Rotor for an electric motor, having a rotor shaft and, mounted on the rotor shaft, a rotor core having a number of core laminations arranged along an axis of the rotor core. Each core lamination includes a central contoured aperture which is traversed by the rotor shaft and which includes at least two radially extending elevations and at least two cutouts positioned between the elevations, wherein, to form a press fit of the core laminations on the rotor shaft, a distance between the free ends of the elevations is less than a diameter of the rotor shaft, and wherein a duct extending peripherally on the rotor shaft is formed by the respective cutout in the successively arranged core laminations.
