Abstract: A device for rotary or linear position sensing includes a stator with a plurality of teeth, an excitation winding wrapped around at least some of the plurality of teeth, and multiple sense windings for detecting changes in voltage output. The windings are in two sets in which each set can independently determine the change in voltage output. A control circuit generates a first output signal representing a relative position of the stator based on excitation of the first sense winding set by the excitation winding and a second output signal representing a relative position of the stator based on excitation of the second sense winding set by the excitation winding.
