Title
(EN) MOTOR/GENERATOR SYSTEM AND FAULT TOLERANT CONTROL METHOD
(FR) SYSTÈME DE MOTEUR/GÉNÉRATEUR ET PROCÉDÉ DE COMMANDE À TOLÉRANCE AUX PANNES
Abstract
(EN)
A motor control method comprises providing a machine comprising a plurality of windings, a rotor and a stator magnetically coupled to the rotor, coupling a plurality of power converters to the plurality of windings, configuring the plurality of power converters so as to adjust the number of poles of the machine in a low-stress operating mode according to a plurality of operating parameters and after a fault occurs in the machine, configuring the plurality of power converters such that the machine enters a fault tolerant operating mode.
(FR)
La présente invention concerne un procédé de commande de moteur qui comprend la fourniture d’une machine comprenant une pluralité d’enroulements, un rotor et un stator magnétiquement couplé au rotor, le couplage d’une pluralité de convertisseurs de puissance à la pluralité d’enroulements, la configuration de la pluralité de convertisseurs de puissance de façon à ajuster le nombre de pôles de la machine dans un mode de fonctionnement à faible contrainte en fonction d’une pluralité de paramètres de fonctionnement et après qu’un défaut s'est produit dans la machine, la configuration de la pluralité de convertisseurs de puissance de sorte que la machine passe dans un mode de fonctionnement tolérant aux pannes.
