摘要： A hysteresis brake is provided, such as for an electric camshaft adjuster, has with an excitation coil, a stator with an inner and outer stator part, and a moveable rotor with a hysteresis band which is movable between the inner and outer stator part. The excitation coil, which produces a main magnetic flux for a magnetic adjuster is arranged between the inner and outer stator part. A sensor enables the rotor and/or the hysteresis band to receive a secondary magnetic flux caused by the main magnetic flux, or enables the excitation coil to receive the main flux. An evaluation and control unit evaluates the magnetic flux received and determines angle and/or rotational speed information from detected changes of the magnetic flux.
