Abstract: front page image
(EN)A method for measuring a rotor angular position of a permanent-magnet synchronous motor and a position sensor. The position sensor includes a hardware circuit, a probe coil (102) and a signal plate (3). The hardware circuit generates a high-frequency oscillating current. The high-frequency oscillating current causes the probe coil (102) to generate alternating magnetic field. The magnetic field induces eddy currents on the surface of the signal plate (3). The eddy currents cause an effective impedance of the probe coil (102) to change. The effective impedance corresponds to the rotor angular position.
(FR)L'invention porte sur un procédé de mesure d'une position angulaire de rotor d'un moteur synchrone à aimant permanent et sur un capteur de position. Le capteur de position comprend un circuit matériel, une bobine de sonde (102) et une plaque de signal (3). Le circuit matériel génère un courant oscillant haute fréquence. Le courant oscillant haute fréquence amène la bobine de sonde (102) à générer un champ magnétique alternatif. Le champ magnétique induit des courants de Foucault sur la surface de la plaque de signal (3). Les courants de Foucault amènent une impédance effective de la bobine de sonde (102) à changer. L'impédance effective correspond à la position angulaire du rotor.
