In an AC drive, a method for stator flux oriented control of a waveform generator providing switching signals to an inverter supplying pulse width modulated current to a three-phase, variable frequency induction motor is provided. The method includes generating a quadrature axis stator voltage signal, a direct axis stator voltage signal, and a stator frequency signal to which switching signals from the waveform generator to the inverter are responsive.
Méthode permettant, dans un dispositif d'entraînement c.a., la commande par flux statorique d'un générateur d'ondes transmettant des signaux de commutation à un onduleur, lequel fournit un courant modulé par impulsions variables en durée à un moteur triphasé à induction à fréquences variables. Comprend la production de composantes transversale et longitudinale de tension de stator, et d'un signal de fréquence de stator à quoi répondent des signaux de commutation transmis du générateur d'ondes à l'onduleur.
