Title
(EN) DIGITAL POWER OPTIMIZATION SYSTEM FOR AC INDUCTION MOTORS
(FR) SYSTEME NUMERIQUE D'OPTIMISATION DE PUISSANCE POUR MOTEURS A INDUCTION A COURANT ALTERNATIF
Abstract
(EN)
A method and device are disclosed for the improvement of the efficiency of operation of AC induction motors. The method and device are based upon tuning the motor control system such that the time interval between the turn-on of a bi-directional switching means and the time of sensing the resultant inrush current through the stator is maintained constant as the load is varied.
(FR)
L'invention concerne un procédé et un dispositif servant à améliorer l'efficacité du fonctionnement de moteurs à induction à courant alternatif. Ce procédé et ce dispositif sont basés sur le réglage du système de commande du moteur, de façon à maintenir constant l'intervalle temporel entre la mise en fonction d'un moyen de commutation bidirectionnel et le moment de détection du courant de démarrage résultant à travers le stator, simultanément à la variation de la charge.
