The invention relates to a rotation-angle sensor (10) comprising a stator element (12), a rotor element (14) mounted to rotate relative to the stator element (12) about an axis of rotation (A), the rotation angle being detectable by means of an inductive coupling between the rotor element (14) and the stator element (12). According to the invention, at least one compensation element is located onthe stator element (12) and the at least one compensation element has at least one compensation transmitter coil (22, 28) for emitting an electromagnetic compensation alternating field and at least one compensation receiver coil (30) for receiving electromagnetic alternating fields. The rotor element (14) has at least one first electrically conductive portion (32). The at least one first electrically conductive portion (32) is both located on the rotor element (14) and inductively coupled to the at least one compensation transmitter coil (22, 28) and the at least one compensation receiver coil(30) such that when the at least one compensation transmitter coil (22, 28) emits the electromagnetic compensation alternating field, an alternating voltage induced in the at least one compensation receiver coil (30) is primarily dependent on a relative mutual radial location of the stator element (12) and the rotor element (14) with respect to the axis of rotation (A).
