Title (EN) GENERATING A COIL SWITCHING SIGNAL FOR A BRUSHLESS DC MOTOR
(FR) PRODUCTION D'UN SIGNAL DE COMMUTATION D'ENROULEMENT POUR MOTEUR CC SANS BALAI
Abstract: front page image
(EN)Some embodiments provide a system that generates a coil switching signal for a brushless DC motor. During operation, the system determines a magnetic field of the brushless DC motor at a first time and a magnetic field of the brushless DC motor at a second time. Then, the coil switching signal is generated based on a relationship between the magnetic field determined at the first time and a first predetermined threshold, and the magnetic field determined at the second time and a second predetermined threshold.
(FR)Certains modes de réalisation se rapportent à un système qui produit un signal de commutation d'enroulement pour moteur CC sans balai. Pendant le fonctionnement, le système détermine un champ magnétique du moteur CC sans balai à un premier temps et un champ magnétique du moteur CC sans balai à un second temps. Ensuite, le signal de commutation d'enroulement est produit sur la base d'une relation entre le champ magnétique déterminé au premier temps et un premier seuil prédéfini, et le champ magnétique déterminé au second temps et un second seuil prédéfini.
