Title (EN) MOTOR CONTROL CIRCUIT AND METHOD THAT REDUCE SPEED JITTER OF AN ELECTRIC MOTOR
(FR) CIRCUIT ET PROCÉDÉ DE COMMANDE DE MOTEUR QUI RÉDUISENT L'INSTABILITÉ DE LA VITESSE D'UN MOTEUR ÉLECTRIQUE
Abstract: front page image
(EN)Motor control circuits and associated methods to control an electric motor provide a plurality of drive signal channels at the same phase, resulting in reduced jitter in the rotational speed of the electric motor.
(FR)L'invention porte sur des circuits de commande de moteurs et sur des procédés correspondants pour commander un moteur électrique, qui fournissent une pluralité de canaux de signaux d'alimentation à la même phase, avec pour résultat une instabilité réduite de la vitesse de rotation du moteur électrique.
