Abstract
The present invention relates to an arrangement for measuring a force and/or a torque on a machine element extending in an axis, using the inverse magnetostrictive effect. The machine element has at least one permanent magnetization. The permanent magnetization extends along a closed magnetization path. The magnetization path runs preferably at least partially along the surface of the machine element. The arrangement further includes at least one magnetic field sensor which is arranged opposite the machine element. The magnetic field sensor serves to determine a magnetic field and is designed to measure at least one vector component of a magnetic field coming from the machine element, which field is produced on the one hand by the permanent magnetization and on the other hand by the force and/or by the torque. According to the invention, the orientation of the permanent magnetization relative to the axis changes along the magnetization path.
