Title (EN) METHOD AND DEVICE FOR ROTOR POSITION DIAGNOSIS IN AN ELECTRIC-MOTOR DRIVE
(FR) PROCÉDÉ ET DISPOSITIF DE DIAGNOSTIC DE POSITION DE ROTOR DANS UN ENTRAÎNEMENT À MOTEUR ÉLECTRIQUE
(DE) VERFAHREN UND VORRICHTUNG ZUR ROTORLAGEDIAGNOSE IN EINEM ELEKTROMOTORISCHEN ANTRIEB
Abstract:
(EN) The invention relates to a method and to a device for rotor position diagnosis in an electric-motor drive, which drive has a sensor unit (S) arranged on the rotor or on a shaft connected to the rotor for determining the rotor position, which sensor unit has a plurality of magnetoresistive sensor elements (TMR), which are interconnected to each other in order to form at least two measuring bridge circuits, which serve as full bridges (VB, VB') and provide at least two measurement signals (cos, sin), which are phase-shifted with respect to each other, for signal processing. In order to detect errors occurring in the measurement signals, two half bridge signals (cosP, cosN), which are provided by the half bridges (HB1, HB2) of the same full bridge (VB), are combined with each other and evaluated in the signal processing.
(FR) L'invention concerne un procédé et un dispositif de diagnostic de la position du rotor d'un entraînement à moteur électrique qui comporte une unité de détection (S), disposée sur le rotor ou sur un arbre relié à celui-ci, pour déterminer la position du rotor, laquelle unité de détection comporte une pluralité d'éléments de détection magnéto-résistifs (TMR) qui sont interconnectés pour former au moins deux circuits en pont de mesure servant de ponts intégraux (VB, VB') et délivrant au moins deux signaux de mesure (cos, sin), déphasés les uns par rapport aux autres, pour effectuer un traitement du signal. Pour détecter les erreurs se produisant dans les signaux de mesure, deux signaux de demi-pont (cosP, cosN), délivrés par les demi-ponts (HB1, HB2) du même pont intégral (VB), sont combinés entre eux et évalués dans le traitement de signal.
(DE) Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Rotorlagediagnose in einem elektromotorischen Antrieb, der zur Bestimmung der Rotorlage eine an dem Rotor oder an einer damit verbundenen Welle angeordnete Sensoreinheit (S) aufweist, die mehrere magnetoresistive Sensorelemente (TMR) aufweist, die miteinander verschalten sind, um mindestens zwei als Vollbrücken (VB, VB') dienende Messbrückenschaltungen zu bilden, die mindestens zwei zueinander phasenverschobene Messsignale (cos, sin) für eine Signalverarbeitung zu liefern. Zur Erkennung von in den Messignalen auftretenden Fehlern werden zwei Halbbrückensignale (cosP, cosN), die von den Halbbrücken (HB1, HB2) derselben Vollbrücke (VB) geliefert werden, in der Signalverarbeitung miteinander kombiniert und ausgewertet.
