Abstract
In at least one general aspect, an inductive sensor can include a shaft having an axis of rotation, and a rotor physically coupled to the shaft and including a rotor coil. The rotor and the rotor coil can be aligned along a plane orthogonal to the axis of rotation. The inductive sensor can include a stator including a stator layer, an excitation coil, and an eccentricity receiver coil where the excitation coil and the eccentricity receiver coil are physically coupled to the stator layer.
