Verfahren und System zur Bestimmung der Innentemperaturen einer elektrischen Maschine, die synchron mit den Zustandsbeobachtern läuft

摘要

The invention relates to a method for determining internal temperatures (2) (coil and magnet temperatures) of a synchronous electric machine (4) by means of state observers of the resistance of the coils and the magnetic flux. of the magnet. The invention also relates to a method of diagnosis, a method and a control system (3) of a synchronous electric machine from determined internal temperatures.
