The first and second electromagnets (120, 130) each comprising a magnetic circuit (121; 131) essentially constituted by a first ferromagnetic material and co-operating with said ferromagnetic body to define an airgap, together with an excitation coil (122; 132) powered from a power amplifier whose input current is servo-controlled as a function of the position of the ferromagnetic body relative to the magnetic circuits of the first and second electromagnets. The position of the ferromagnetic body (110) being measured from the inductance detected between the two electromagnets (120, 130) in response to simultaneous injection into both opposing electromagnets of a sinusoidal current at a frequency that is greater than the closed loop passband of the system.

The detector device comprises a calculation circuit (40) having measurement means (41) for measuring the voltage Vu of a given phase U, first subtracter means (44) for subtracting from the voltage Vu as determined by the measurement means (41) a magnitude (C1) corresponding to the resistive voltage drop across the resistance (Rm) of the winding under consideration carrying a current iu, integrator means (42) for integrating the signal from the first subtracter means (44), second subtracter means (47) for subtracting from the signal delivered by the integrator means (42) a magnitude (C2) corresponding to the inductive voltage drop across the inductance (Lm) of the winding under consideration carrying the current iu, and a comparator circuit (43) for detecting the zero crossings of the rotor flux sinewave signal as delivered by the second subtracter means (47) and thus for supplying an information signal identifying the angular position of the rotor relative to the stator. The angular position detector device avoids any need to make use of sensors of the Hall effect type or of the inductive type.
