Title (EN) CONTROL OF AN ELECTRIC MACHINE
(FR) COMMANDE D'UNE MACHINE ÉLECTRIQUE
Abstract: front page image
(EN) A method of controlling a single- phase permantent- magnet electric machine, the method comprising exciting a winding of the electric machine in advance of zero-crossings of back emf in the winding by a fixed advance time over a range of speeds. Additionally, a control system for an electric machine, and a vacuum cleaner incorporating the control system and electric machine.
(FR) L'invention porte sur un procédé de commande d'une machine électrique à aimant permanent monophasé, le procédé comprenant l'excitation d'un enroulement de la machine électrique en avance de passages par zéro de la force contre-électromotrice dans l'enroulement par un temps d'avance fixe sur une plage de vitesses. L'invention porte en outre sur un système de commande pour machine électrique, et sur un aspirateur incorporant le système de commande et la machine électrique.
