Patent ID: 7576533

Claim:
An inductive angular-position sensor, comprising: a partially metallized disk ( 3 ) that moves in rotation around the axis of revolution (A) of the disk; a feeding means ( 11 ); and a stator that comprises a i) primary coil ( 6 ), with a second axis that is essentially merged with said axis of revolution, connected to the feeding means ( 11 ), and ii) several secondary coils ( 7 , 8 , 9 , 10 ) configured to allow an inductive coupling between said primary coil and said secondary coils, wherein an axis of each of the secondary coils is essentially parallel to said axis of revolution, wherein said secondary coils are arranged in pairs essentially symmetrical relative to said axis of revolution, so as to form one or more pairs of secondary coils, wherein said secondary coils of each pair are connected i) to one another both in series and in phase opposition relative to one another, and ii) to terminals of a measuring means ( 12 , 13 ) configured to generate an output signal depending on a voltage at the terminals, and wherein said feeding means ( 11 ) is a pulse generator, and wherein the primary coil ( 6 ) and the secondary coils ( 7 , 8 , 9 , 10 ) occupy a same plane.
