Abstract
A position sensor is provided. The position sensor includes a target and a segment sensor element. The segment sensor element defines a circumferential direction and a radial direction. The segment sensor element includes a transmit coil. The segment sensor element includes a plurality of receive coils positioned within a space defined by the transmit coil. The plurality of receive coils are offset relative to one another. The shape of each of the plurality of receive coils corresponds to a periodic waveform having a radial width that varies along the circumferential direction. Furthermore, the shape of at least one receive coil of the plurality of receive coils is distorted along at least one of the radial direction or the circumferential direction.
