Title (EN) ELECTRIC MOTOR CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE D"UN MOTEUR ELECTRIQUE
Abstract: front page image
(EN)This control device is used in connection with a motor comprising a magnetic rotor and at least two magnetic stator circuits coupled with respective coils (b1, b2). A logic circuit (21) is arranged to alternatively feed drive pulses to both coils and to connect the coil which is not fed to a detection circuit (24, 25) the output of which is connected to the logic circuit in order to determine the duration of a feed pulse or to trigger a new feed pulse. This control device allows the current consumption of the motor as well as the locking torque to be reduced, since the servo control obtained insures the rotor positionning in case an important disturbance should occur.
(FR)Le dispositif de commande est utilise en rapport avec un moteur comportant un rotor aimante et au moins deux circuits magnetiques de stator couples avec des bobines respectives b1, b2. Un circuit logique (21) est agence pour alimenter alternativement l"une et l"autre des bobines en impulsions d"entrainement et pour brancher la bobine non alimentee sur un circuit de detection (24, 25) dont la sortie est reliee au circuit logique pour determiner la duree d"une impulsion d"alimentation ou pour declencher une nouvelle impulsion d"alimentation. Ce dispositif de commande permet de reduire la consommation en courant du moteur ainsi que le couple de verrouillage, l"asservissement realise assurant le positionnement du rotor en cas de perturbation importante.
