Rotating angle sensors, stator elements and rotor elements for rotational angle sensors

摘要

The present invention includes a stator element 12 and a rotor element 14 mounted to rotate about an axis of rotation A with respect to the stator element 12, To the rotation angle sensor (10) which can be detected by inductive coupling between the stator element (12) and the stator element (12). According to the invention, at least one compensation element is arranged on the stator element (12), said at least one compensation element comprises at least one compensation transmission coil (22, 28) for the delivery of an electromagnetic compensating alternating magnetic field, And at least one compensation receiving coil 30 for receiving a magnetic field. The rotor element 14 comprises at least one first electrically conductive portion 32. The at least one first electrically conductive portion 32 is disposed on the rotor element 14 and is inductively coupled to the at least one compensation transmission coil 22 and 28 and the at least one compensation reception coil 30, The compensating alternating voltage induced in the at least one compensating receiving coil 30 is mainly transmitted to the rotor element 14 for the rotational axis A when the electromagnetic compensating alternating magnetic field is transmitted through the compensating transmitting coils 22, And the relative radial orientation of the stator elements 12.
