Abstract
The magnetoelastic torque sensor includes a shaft that is magnetized in a first axial section in a first circumferential direction and to which a torque to be measured can be applied; a first magnetic field sensor outside of the shaft for recording a magnetic field, which is generated by the first section of the shaft and independent of the applied torque. The first magnetic field sensor comprises a first 3D Anisotropic MagnetoResistance (3D-AMR) sensor.
