PROCEDE ET DISPOSITIF POUR PILOTER L'ALIMENTATION D'UN MOTEUR ASYNCHRONE UTILISABLE NOTAMMENT COMME ACTIONNEUR

摘要

Method and device for controlling the supply to an asynchronous motor usable in particular as an actuator in servocontrols. The method of the invention consists in operating the motor with an imposed active flux (active flux PHI 0 equal to the product of the flux PHI times the cosine of the phase shift phi between the rotor electromotive force and the rotor current), by injecting it with a stator current calculated so as to take into account the influence of the rotor current.
