Abstract
A rotary sensor includes a stator element and a rotor element that is rotatably mounted in respect of the stator element about an axis of rotation. A rotary angle can be captured by inductive coupling between the rotor element and the stator element. The rotary sensor further includes a measuring device configured to capture the rotary angle depending on the inductive coupling between the rotor element and the stator element. The stator element has at least one transmission coil for emitting alternating electromagnetic fields and at least two reception coils for capturing alternating electromagnetic fields, when the measuring device is configured to excite the at least one transmission coil with at least two mutually different frequencies for emitting at least two alternating electromagnetic fields.
