Abstract
A stator for an electric motor, encompassing 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 including a carrier portion having an externally located surface; the externally located surface facing in a radial direction orthogonal to the longitudinal axis; the carrier portion including 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 including a cover at at least one axial longitudinal end of the carrier portion; the cover encompassing a connecting configuration having cover plastic compatible with or identical to the carrier plastic; the plastic casing including a counterpart connecting configuration; the connecting configuration being welded to the counterpart connecting configuration.
