Abstract: An eddy-current angular displacement sensor includes a stator including a coil array including N coils, wherein N is an integer greater than 1, one exciting circuit connected via a switching system to the coil array that generates a changing magnetic field, a measuring circuit connected via a switching system to the coil array that generates output signals that depend on the eddy currents caused by the changing magnetic field, and a partially metallized rotor, through which the eddy currents travel, and the angular displacement of which would be determined by the output signals.
