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.

Abstract: Swinging choke with a winding body, a core, which is integrated into the winding body such that the core forms at least one air gap in the winding body, at least one main winding which is wound onto the winding body, wherein the main winding is designed for a high voltage, and at least one ancillary winding the number of turns of which is designed such that a low voltage can be tapped and which is arranged above or close to the air gap.
