Abstract: An apparatus comprises a support structure, one or more oscillator coils, a first sense coil, and a second sense coil. The one or more oscillator coils have a circular winding pattern around an axis of rotation for a target. The first sense coil has a coil winding pattern arranged around the axis and surrounded by the circular winding pattern of the one or more oscillator coils. The second sense coil has a coil winding pattern arranged around the axis and surrounded by the circular winding pattern of the one or more oscillator coils. The coil winding pattern of the second sense coil offset from the coil winding pattern of the first sense coil by an angle of substantially Φ degrees, where Φ=60°/N, and N is an integer number of pole pairs of the apparatus.
