Abstract
A torque sensor can measure torque introduced into an upper shaft that is rotatable around a longitudinal axis and is connectable to a lower shaft via a torsion rod. A first component is connectable to the upper shaft, and a second component is connectable to the lower shaft. The components have surfaces that protrude in a longitudinal direction and at least partially overlap. A sensor coil that can generate a high-frequency alternating magnetic field is arranged on one of the surfaces of one component, and a metallic element is arranged on one of the surfaces of the other component. A torque introduced into the upper shaft causes a change in distance between the sensor coil and the metallic element. A device can measure a frequency change of the alternating magnetic field caused by the change in distance and determine the torque introduced into the upper shaft.
