Abstract:
An inductive torque sensor for a motor vehicle is provided that has an excitation coil, an oscillator circuit which is coupled with the excitation coil and which generates a periodic alternating voltage signal and couples it with the excitation coil during operation, a stator circuit board with first receiver means and second receiver means with each having a number of periodically repeated receiver structures, at least two rotors which can be rotated relative to one another and relative to the stator circuit board and which influence the strength of the inductive coupling between the excitation coil and the receiver means, and evaluation means suitable for evaluation of the signals induced in the receiver means.
