Abstract

Disclosed is a position sensor, in particular a rotor position sensor, comprising a base. A track that is provided with a conducting coating is formed within the surface of the base relevant for evaluating signals. Since the track is formed within the base, the desired position-dependent modulation of the eddy current behavior is obtained by design measures, resulting in low manufacturing tolerance and reduced production costs.
