1. A stator for an electric motor, the stator comprising a carrier component that extends along a virtual longitudinal axis defining an axial direction, the carrier component that is notionally passed through centrally by the virtual longitudinal axis comprising a carrier portion having an externally located surface; the externally located surface facing in a radial direction orthogonal to the virtual longitudinal axis; the carrier portion comprising a metal framework overmolded by a thermoplastic carrier plastic, so that the metal framework is surrounded at least in portions by a plastic casing made of carrier plastic; the stator comprising a cover at at least one axial longitudinal end of the carrier portion; the cover comprising a connecting configuration having cover plastic compatible with or identical to the carrier plastic; the plastic casing comprising a counterpart connecting configuration; the connecting configuration being welded to the counterpart connecting configuration, wherein one of the connecting configuration and the counterpart connecting configuration comprises an axially extending projection, and the respective other of the connecting configuration and the counterpart connecting configuration comprises an axially extending recess that at least partly receives the one of the connecting configuration and the counterpart connecting configuration, the weld between the connecting configuration and the counterpart connecting configuration includes the axially extending projection being welded to the axially extending recess.
