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.
