Title (EN) MOTOR CONTROL USING PHASE CURRENT AND PHASE VOLTAGE
(FR) COMMANDE DE MOTEUR UTILISANT UN COURANT DE PHASE ET UNE TENSION DE PHASE
Abstract:
(EN) Methods and apparatus to control a three-phase BLDC motor using phase current and phase voltage at zero current detection and a driving current derived from a bus current, for example. The driving current can be combined with a difference angle with an output provided to a controller to control a speed of the motor.
(FR) L'invention porte sur des procédés et sur un appareil permettant de commander un moteur BLDC triphasé à l'aide d'un courant de phase et d'une tension de phase à une détection de courant nul et d'un courant d'attaque dérivé d'un courant de bus, par exemple. Le courant d'attaque peut être combiné avec un angle de différence avec une sortie fournie à un contrôleur pour commander la vitesse du moteur.
