Title (EN) MOTOR DRIVING APPARATUS
(FR) APPAREIL D'ENTRAÎNEMENT D'UN MOTEUR
(KO) 모터 구동 장치
Abstract:
(EN) The present invention relates to a motor driving apparatus and, more specifically, to a motor driving apparatus for selectively performing identical phase overmodulation compensation or minimum distance overmodulation compensation according to a command speed when an output voltage command value of an inverter indicates an overmodulation voltage.
(FR) La présente invention concerne un appareil d'entraînement d'un moteur, et plus précisément un appareil d'entraînement d'un moteur permettant d'effectuer sélectivement une compensation de surmodulation de phase identique ou une compensation de surmodulation de distance minimale en fonction d'une vitesse de commande lorsqu'une valeur de commande de tension de sortie d'un onduleur indique une tension de surmodulation.
(KO) 본 발명은 모터 구동 장치에 관한 것으로, 보다 상세하게는 인버터의 출력 전압 지령치가 과변조 전압인 경우, 지령 속도에 따라 동일 위상 과변조 보상 또는 최소 거리 과변조 보상을 선택적으로 수행하는 모터 구동 장치에 관한 것이다.
