Abstract
Electric motor, in particular series-, split-pole- and single-phase synchronous motor, having a bent stator iron, pole shoe shanks formed by the stator iron which form pole shoes at their free ends. Induction coils are provided on the pole shoe limbs. A rotatable, radially magnetized permanent magnetic rotor is present between the pole shoes. In this electric motor the oppositely located pole shoes are formed at the end faces of the pole shoe shanks. The rotor shaft intersects the central longitudinal line of the two pole shoe shanks. Finally, the parts of the pole shoe shanks facing away from the pole shoes are bent and interconnected in the form of a bridge.
