Title (EN) MOTOR DRIVE DEVICE
(FR) DISPOSITIF D'ENTRAÎNEMENT DE MOTEUR
(JA) モータ駆動装置
Abstract: front page image
(EN) When increasing the number of rotations under a two-phase modulation scheme, a control device (100) changes the modulation scheme from the two-phase modulation scheme to a three-phase modulation scheme if the number of samplings for a control modulation-factor value per electrical cycle from a target modulation-factor waveform decreases to less than a prescribed number.
(FR) Lorsqu'on augmente le nombre de rotations dans un schéma de modulation en deux phases, un dispositif de commande (100) modifie le schéma de modulation pour le transformer en schéma de modulation en trois phases si le nombre d'échantillons pour une valeur de facteur de modulation de témoin par cycle électrique provenant d'une forme d'onde de facteurs de modulation cible baisse en dessous d'un nombre prescrit.
(JA)  制御装置(100)は、2相変調方式で回転数を上昇させているときに、目標変調率波形からの電気角1周期あたりの制御用変調率値サンプリング数が所定数未満に低下した場合には、変調方式を2相変調方式から3相変調方式に変更する。
