Abstract
Inductive angular-position sensor, including a partially metallized disk that moves in rotation around its axis of revolution; and a stator that includes a primary coil and several secondary coils, whereby the secondary coils are arranged essentially symmetrically in pairs relative to the axis of revolution, so as to form one or more pairs of secondary coils, whereby the secondary coils of each pair are connected, on the one hand, to one another, in series and in phase opposition relative to one another, and, on the other hand, to the terminals of a measuring element that can generate an output signal that depends on the voltage at the terminals of the pair.
