Abstract
(EN)
This motor control device 10 comprises: a current acquisition unit 12 that acquires a limited current ILdc that can flow from a battery 200 to a brushless motor 100; a voltage acquisition unit 11 that acquires a power supply voltage Vdc applied from the battery 200 to the brushless motor 100; and a command current determination unit 13 that determines a d-axis command current Id* and a q-axis command current Iq*. The command current determination unit 13 determines the d-axis command current Id* and the q-axis command current Iq* on the basis of a power limiting circle that is current characteristics of the d-axis and the q-axis based on an inner product of a voltage vector and a current vector, and a voltage limiting circle that is the d-axis and the q-axis current characteristics based on the scalar product of the power supply voltage Vdc and an angular velocity of the brushless motor 100.

La présente invention concerne un dispositif de commande de moteur 10 comprenant : une unité d'acquisition de courant 12 qui acquiert un courant limité ILdc qui peut circuler entre une batterie 200 et un moteur sans balai 100 ; une unité d'acquisition de tension 11 qui acquiert une tension d'alimentation en courant continu appliquée entre la batterie 200 et le moteur sans balai 100 ; et une unité de détermination de courant de commande 13 qui détermine un courant de commande d'axe d Id* et un courant de commande d'axe q Iq*. L'unité de détermination de courant de commande 13 détermine le courant de commande d'axe d Id* et le courant de commande d'axe q Iq* sur la base d'un cercle de limitation de puissance qui représente les caractéristiques du courant d'axe d et d'axe q sur la base d'un produit interne d'un vecteur de tension et d'un vecteur de courant, et d'un cercle de limitation de tension qui représente les caractéristiques du courant d'axe d et les caractéristiques de courant d'axe q sur la base du produit scalaire de la tension d'alimentation en courant continu et d'une vitesse angulaire du moteur sans balai 100.
