Abstract

The invention relates to an electric motor having a U-shaped stator iron such as a series-, split-pole- or single-phase synchronous motor. Between the free shank ends of the stator, pole shoes are formed, and on the shanks, induction coils are provided. The shanks of the stator iron in the area between the pole shoes and the coils are bent with respect to the central plane of the stator iron in such manner that the shaft of the rotor with the central plane of the stator iron encloses an angle differing from the perpendicular to the central plane.
