<p>Angle sensor comprising at least a first and a second detection means (10,20), each detection means (10,20) comprising a stator (11,21) consisting of electromagnetic means (13,14, 23,24) forming inductive detectors and a rotor (12,22) having at its periphery turned towards the stator (11,21), a ring made of ferromagnetic material. The rotors (12,22) of the detection means (10,20) are mounted offcentred in opposite directions on a common rotating shaft (40), the windings of the said inductive detectors (13,14, 23,24) constituting the different branches of a bridge circuit (50) which are excited by a single carrier signal supplied by a generator (30). Application of the angle sensor in particular for driving a synchronous motor with permanent magnets. <IMAGE></p> |
