Abstract

The invention refers to a Rotary Solenoid comprising a stator and rotor that can rotate around a rotational axis. The rotor has a rotor shaft on which a rotor disc is arranged. The rotor disc is, seen in the direction of the circumference, polarized alternating magnetically. The stator carries at least one coil. On the coil windings of electrically conducting wire are provided. For guiding the magnetic flow of the magnetic field generated by the coil a pole face consisting of several partial pole faces is provided.
