A drive system for a brushless DC motor (10) uses pulse width modulation (20), and phase timing advancement to maintain a constant power output during high speed use. The arrangement is well suited for driving a brushless motor (10) in an electric vehicle and the like.
Un système d'excitation pour un moteur à courant continu sans balai (10) utilise une modulation de largeur d'impulsion (20) et un système d' avancement du réglage de phases pour maintenir une sortie de puissance constante pendant l'utilisation à vitesse élevée. Cette configuration convient particulièrement pour exciter un moteur sans balai (10) dans un véhicule électrique ou similaire.
