Abstract: An inductive sensor for detecting a position. In one example, the sensor includes an oscillator circuit which generates an AC voltage signal and couples it into an exciter coil, and a pair of receiving coils including first and second receiving coils which each form a repeating loop structure and whose arrangement forms a receiving geometry. The exciter coil is arranged to induce a signal in each receiving coil based on the coupled AC voltage signal. An evaluation circuit outputs a sensor signal that depends on the position to be detected, based on the signals induced in the receiving coils, and a movable coupling element influences the strength of the inductive couplings between the exciter coil and the receiving coils as a function of the position to be detected. The receiving coils are located in a geometrical position having an intermediate space between them and are electrically connected to each other.

Abstract: The invention relates to a device (9) for generating a measurement signal (19) that is dependent on a torque (13) exerted on a torsion shaft (10) around a rotation axis (8) comprising: a magnet ring (16) fixed to a first axial position of the torsion shaft (10) and having a predefined number of magnet poles (28, 29) for generating a magnetic field (17), characterized by a magnet sensor (18) that is fixed to a second axial position of the torsion shaft (10) different from the first axial position and that includes a first sensor element (33) located in a radial plane (36) around the rotation axis (8) and outputting a first sensor signal dependent on the magnetic field (17) arriving the first sensor element (33), and a second sensor element (34, 38) located in the radial plane (36) of the first sensor element (33) but spaced from the first sensor element (33) with a distance (35) that is smaller that a cirumferencial extension of two neighboring magnet poles and outputting a second sensor signal dependent on th

Abstract: A stator to guide a location-dependent magnetic field around a rotation axis including a first stator ring and a second stator ring arranged concentrically to the first stator ring. First claws project axially from the first stator ring in the direction of the second stator ring and are arranged circumferentially around a rotation axis and at a distance with the first claw gaps engaging in second claw gaps between second claws which are arranged circumferentially around the rotation axis, and protrude axially in the direction of the first stator ring at a distance to the second claw gaps. Each of the first and second claws includes a claw head. In at least one of the first claw gaps and in one of the second claw gaps relative to the corresponding claw head, a stator fastening element is arranged to fasten the first and second stator rings.

Abstract: A stator to guide a location-dependent magnetic field in a circumferential direction around a rotation axis. In one example, the stator includes a first stator ring revolving around the rotation axis, and a second stator ring revolving around the rotation axis and arranged concentrically with the first stator ring. The first and second stator rings include claws which are arranged so as to revolve around the rotation axis and at a distance from one another in the circumferential direction and engage with one another at least on a toothing axial plane. The claws are separated from one another by an air gap so that, when the magnetic field is arranged in the toothing axial plane, the magnetic field is guided towards the stator rings via the claws according to a relative angular position. Each claw has the contour of a mathematically smooth curve when viewed across the circumferential direction.
