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.

Stator fastening in torque sensor

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.
