(FR) PROCÉDÉ DE SURVEILLANCE DU FONCTIONNEMENT D’UNE MACHINE À ROTATION ÉLECTRIQUE
(DE) VERFAHREN ZUM ÜBERWACHEN DES BETRIEBES EINER ELEKTRISCHEN ROTIERENDEN MASCHINE
Abstract:
(EN) The invention relates to a method for monitoring the operation of an electrical rotating machine (2) comprising a rotor (8), a stator (10), and a machine housing (18), in which the rotor (8) and the stator (10) are accommodated. In order to allow the method to be carried out without structural changes to the electrical rotating machine (2), according to the invention, outside the machine housing (18) a first physical value of the stator (10) and a second physical value of the rotor (8) is measured, wherein at least one state variable of the electrical rotating machine (2) is determined from the first physical value and the second physical value.
(FR) L’invention concerne un procédé de surveillance du fonctionnement d’une machine à rotation électrique (2), comprenant un rotor (8), un stator (10) et un carter (18) qui abrite le rotor (8) et le stator (10). Afin de permettre la mise en oeuvre du procédé sans modification de la conception de la machine à rotation électrique (2), l’invention propose de mesurer une première caractéristique physique du stator (10) et une deuxième caractéristique physique du rotor (8) hors du carter (18), la première caractéristique physique et/ou la deuxième caractéristique physique permettant de déterminer au moins une caractéristique d’état de la machine à rotation électrique (2).
(DE) Verfahren zum Überwachen des Betriebes einer elektrischen rotierenden Maschine (2) mit einem Rotor (8), einem Stator (10) und einem Maschinengehäuse (18), in dem der Rotor (8) und der Stator (10) aufgenommen sind. Um eine Durchführung des Verfahrens ohne konstruktive Änderungen an der elektrischen rotierenden Maschine (2) zu ermöglichen, wird vorgeschlagen, dass außerhalb des Maschinengehäuses (18) eine erste physikalische Größe des Stators (10) und eine zweite physikalische Größe des Rotors (8) gemessen wird, wobei aus der ersten physikalischen Größe und der zweiten physikalischen Größe mindestens eine Zustandsgröße der elektrischen rotierenden Maschine (2) ermittelt wird.
