Abstract
An inductive rotary transmitter includes a rotor and a stator, which form a rotary transmitter. A rotor winding is arranged on the rotor, and a stator winding is arranged on the stator. Apart from the rotor winding, the rotor does not have any ferromagnetic or soft-magnetic material parts for inductive coupling to the stator or the stator winding. The annularly closed magnetic field lines for inductive coupling are formed on the stator side via the stator winding and a plurality of separate stator elements, which are produced from ferromagnetic or soft-magnetic material. The stator elements overlap both the rotor winding and the stator winding at a respective mounting point of the stator element and direct the magnetic field lines (M) around the rotor winding and around the stator winding to effect a magnetic coupling.
