Abstract: An electric motor, especially for a fluid-handling system, comprises an external stator and an internal rotor mounted to rotate around an axis. The said external stator comprises a multiplicity of ferromagnetic pole pieces disposed around the axis and having winding cores extending substantially radially, an injection-molded plastic structure having a bushing and, molded thereon, winding supports enveloping the winding cores, as well as stator windings received on the winding supports. The bushing comprises a sleeve having a closed inner face extending radially inside the pole pieces and an end piece that closes the sleeve in the end region. The rotor is disposed inside the sleeve and mounted in a bearing disposed in the end piece.
