Abstract

L'invention concerne un procédé et un dispositif de commande d'un moteur BLDC sans capteur. Le dispositif de commande d'un moteur BLDC sans capteur comprend : une mémoire servant à stocker une instruction ; et un processeur exécutant l'instruction et comportant un compteur chargé en son sein, l'instruction provoquant la réalisation d'un procédé de commande comprenant les étapes consistant : à établir un temps de comptage de période (Tperiod) du compteur ; à calculer un temps de comptage à l'aide du temps de comptage de période établi, et à déterminer la vitesse de rotation du moteur BLDC sans capteur ; à diviser l'impulsion de comptage totale délivrée par le compteur pendant le temps de comptage de période établi en une pluralité de sections correspondant à une pluralité de séquences, afin d'entraîner le moteur BLDC sans capteur conformément à la pluralité de séquences ; à diviser chaque section de la pluralité de sections divisées en une pluralité de sous-sections ; et à compter, pour chaque sous-section de la pluralité de sous-sections, le nombre d'impulsions de comptage délivrées par le compteur, de manière à générer des signaux de commande d'entraînement par section, et à délivrer les signaux de commande d'entraînement générés au moteur BLDC sans capteur.
