Abstract
(EN) A motor drive device (2) is provided with: a single phase inverter 11 for applying an AC voltage to a single phase motor (12); a position sensor 21 attached to the single phase motor (12) and detecting the rotor rotational position of the single phase motor (12) to output a position sensor signal (21a) that is a rotational position detection signal; and a control unit (25) for performing pulse-width modulation control on a plurality of switching elements on the basis of a voltage command and the position sensor signal (21a) that is the rotational position detection signal. The control unit (25) is set with: a phase adjustment angle for adjusting the phase difference between the position sensor signal (21a) that is the rotational position detection signal and the output voltage of the single phase inverter (11); and a lead angle adjustment width corresponding to the range of variation in the position at which the position sensor (21) is attached to the single phase motor (12). The control unit (25) uses the phase adjustment angle and the lead angle adjustment width to set a lead angle phase for a specific number of rotations, said lead angle phase being used for calculating the voltage command.
(FR) Un dispositif d'entraînement de moteur (2) comprend : un onduleur monophasé 11 pour appliquer une tension alternative à un moteur monophasé (12); un capteur de position 21 fixé au moteur monophasé (12) et la détection de la position de rotation du rotor du moteur monophasé (12) pour délivrer en sortie un signal de capteur de position (21a) qui est un signal de détection de position de rotation; et une unité de commande (25) pour effectuer une commande de modulation de largeur d'impulsion sur une pluralité d'éléments de commutation sur la base d'une commande de tension et du signal de capteur de position (21a) qui est le signal de détection de position de rotation. L'unité de commande (25) est configurée avec : un angle d'ajustement de phase pour ajuster la différence de phase entre le signal de capteur de position (21a) qui est le signal de détection de position de rotation et la tension de sortie de l'onduleur monophasé (11); et une largeur d'ajustement d'angle d'attaque correspondant à la plage de variation dans la position au niveau de laquelle le capteur de position (21) est fixé au moteur monophasé (12). L'unité de commande (25) utilise l'angle d'ajustement de phase et la largeur d'ajustement d'angle de sortie pour régler une phase d'angle de sortie pour un nombre spécifique de rotations, ladite phase d'angle de sortie étant utilisée pour calculer la commande de tension.
