Abstract
Device for determining a torque exercised on a shaft, wherein the shaft comprises a first shaft section and a second shaft section, wherein the two shaft sections can be rotated relative to another, with a multi-pole magnetic ring which surrounds the first shaft section and is connected thereto, and a stator holder which is mounted to the second shaft section, wherein two stator elements are mounted to a stator holder and each stator element comprises fingers projecting in an axial or radial direction which are distributed uniformly at least over part of the periphery with gaps between them, wherein the fingers of each stator element are interconnected via a magnetic flux ring, wherein the magnetic flux rings have a mutual separation and a magnetic field sensor is disposed between the magnetic flux rings, wherein at least one magnetic flux concentrator is associated with the magnetic field sensor, wherein the magnetic flux concentrator surrounds the magnetic flux rings.
