Title (EN) ENERGY-EFFICIENT ASYNCHRONOUS MACHINE
(FR) MACHINE ASYNCHRONE À EFFICACITÉ ÉNERGÉTIQUE
(DE) ENERGIEEFFIZIENTE ASYNCHRONMASCHINE
Abstract:
(EN) In a method for determining a flux (4) of an asynchronous machine (1), the flux (4) is adjusted according to a loss (7) of the asynchronous machine (1). Therefore, an apparatus for determining the flux (4) of the asynchronous machine (1) is provided with a model (5) for calculating a loss (7) of the asynchronous machine (1) according to the flux of the asynchronous machine and with a selector device (8) for selecting a flux (7) according to the loss.
(FR) L’invention concerne un procédé permettant de déterminer un flux (4) d’une machine asynchrone (1), selon lequel le flux (4) est ajusté en fonction d’une perte (7) de la machine asynchrone (1). L’invention concerne en conséquence un dispositif destiné à déterminer le flux (4) de la machine asynchrone (1), ledit dispositif comportant un modèle (5) pour calculer une perte (7) de la machine asynchrone (1), en fonction du flux de la machine asynchrone, et un dispositif de sélection (8) pour sélectionner un flux (7), en fonction de la perte.
(DE) Bei einem Verfahren zur Ermittlung eines Flusses (4) einer Asynchronmaschine (1), wird der Fluss (4) in Abhängigkeit eines Verlustes (7) der Asynchronmaschine (1) eingestellt. Demnach ist eine Vorrichtung zur Bestimmung des Flusses (4) der Asynchronmaschine (1), mit einem Modell (5) zur Berechnung eines Verlustes (7) der Asynchronmaschine (1) abhängig vom Fluss der Asynchronmaschine und mit einer Auswahleinrichtung (8) zur Auswahl eines Flusses (7) abhängig vom Verlust vorgesehen.
