Abstract

A torque sensor includes a disk comprising a magnetostrictive, magnetically biased, or magnetizable material, and a magnetic field sensor assembly. A torque acting about an axis of rotation of the disk can be applied to the disk and the magnetostrictive material is configured to generate a magnetic field outside the disk that changes dependent on the effective torque. The magnetic field sensor assembly is configured to output a signal based on the magnetic field generated by the magnetostrictive material, and the torque sensor is configured to determine a value of the acting torque based on the signal that is output.
