Abstract:
A rotary assembly comprising a rotor mounted to rotate in a stator about a mean axis of rotation, and comprising a detector for detecting the radial position of the rotor within the stator, itself comprising three sensors distributed in the stator at substantially 120Â° from one another about the rotor and at equal distances from the mean axis of rotation, wherein:the sensors are inductive sensors placed facing a segment of the rotor that is made of magnetic material; a balanced three-phase sinusoidal voltage source having a neutral point feeds the inductive sensors which are wired in a star configuration; means sense the output voltage between the neutral point of the balanced three-phase voltage source and the connection point common to the star-connected inductive sensors, and deduce therefrom the radial position of the rotor within the stator.
