Abstract
A rotation angle sensor includes a stator element and a rotor element, which is mounted in a rotatable manner about an axis of rotation with respect to the stator element. A rotation angle is captured via inductive coupling between the rotor element and the stator element. A compensation element is arranged on the stator element. The compensation element has a compensation transmitting coil configured to emit an alternating electromagnetic compensation field and at least one compensation receiving coil configured to receive alternating electromagnetic fields. The rotor element has a first electrically conductive section. The first electrically conductive section is arranged on the rotor element and is inductively coupled to the compensation transmitting coil and to the at least one compensation receiving coil of the compensation element.
