Abstract

A rotation angle detection sensor system for a rotational body is provided, which has a reduced sensitivity against an interfering magnetic field and an interfering electric field. The rotation angle detection sensor system comprises an encoder structure that is attached to the rotational body of a machine and is movable along with this rotational body. A stationary sensor assembly is positioned opposite to this encoder structure and supplies at least one sensor signal for determining the angle position. The sensor assembly includes a first inductive element, the inductance of which is dependent on the angle position of the encoder structure.
