Abstract
An inductive position sensor including a stator element having an exciter coil to which a periodic alternating voltage is applied and having a receiving system, wherein the signal of the exciter coil is inductively coupled into the receiving system. A rotor element influences the strength of the inductive coupling between the exciter coil and the receiving system according to its angular position relative to the stator element. An evaluation circuit determines the angular position of the rotor element relative to the stator element from the voltage signals induced in the receiving system. The position sensor has an unambiguous range E, in which the angular position can be unambiguously determined. The receiving system extends over a first angular range, wherein the first angular range is N=n*E where n≥1, and the exciter coil extends over a second angular range, wherein the second angular range is N=m*E where m≥2.
