Title (EN) DEVICE AND METHOD FOR DETERMINING THE ROTOR POSITION
(FR) DISPOSITIF ET PROCÉDÉ POUR DÉTERMINER LA POSITION DU ROTOR
(DE) VORRICHTUNG UND VERFAHREN ZUR BESTIMMUNG DER ROTORPOSITION
Abstract:
(EN) The invention relates to a device and to a method for determining the rotor position of a permanent-magnet synchronous motor (1), wherein an excitation signal having a low-frequency component (NF) and at least and at least one high-frequency component (HF) is applied to the motor terminals and the rotary position of the rotor (2) is determined from the high-frequency component (HF) and the enveloping of the response function received as a measuring signal.
(FR) L'invention concerne un dispositif et un procédé pour déterminer la position du rotor d'un moteur synchrone à aimants permanents (1), un signal d'excitation comportant une composante basse fréquence (NF) et au moins une composante haute fréquence (HF) étant appliqué aux bornes du moteur, et la position de rotation du rotor (2) étant déterminée à partir de la composante haute fréquence (HF) et des enveloppes de la fonction de réponse obtenue en tant que signal de mesure.
(DE) Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Ermittlung der Rotorposition eines Permanentmagnet-Synchronmotor (1), wobei an dessen Motorklemmen ein Anregungssignals mit einer niederfrequente Komponente (NF) und wenigstens eine hochfrequente Komponente (HF) angelegt wird und die Drehlage des Rotors (2) aus der hochfrequenten Komponente (HF) und der Einhüllenden der als Messsignal erhaltenen Antwortfunktion ermittelt wird.
