Title (EN) STEPPING MOTOR DRIVE METHOD AND DRIVE DEVICE
(FR) PROCEDE ET DISPOSITIF D'ENTRAINEMENT DE MOTEUR PAS A PAS
(JA) ステッピングモータの駆動方法および駆動装置
Abstract: front page image
(EN) A drive device includes: a 2-power source switching circuit for selectably connecting a high-voltage power source and a low-voltage power source to a power supply path to a motor coil; and a control circuit for controlling the 2-power source switching circuit. Until a power source switching moment when the motor rpm reaches a predetermined rpm, the control circuit keeps the 2-power source switching circuit OFF and connecting only the low-voltage power source to the power supply path. When the motor has reached the predetermined rpm, the control circuit turns the 2-power source switching circuit ON and connects the high-voltage power source to the power supply path.
(FR) L'invention concerne un dispositif d'entraînement comprenant: un circuit de commutation à deux sources d'alimentation permettant de connecter de manière sélective une source d'alimentation haute tension et une source d'alimentation basse tension à un enroulement de moteur, et un circuit de commande permettant de commander le circuit de commutation à deux sources d'alimentation. Jusqu'au moment de la commutation d'une source d'alimentation, lorsque le moteur rpm atteint un rpm prédéterminé, le circuit de commande maintient le circuit de commutation à deux sources d'alimentation fermé et connecte uniquement la source d'alimentation basse tension au chemin d'alimentation. Lorsque le moteur atteint le rpm prédéterminé, le circuit de commande ouvre le circuit de commutation à deux sources d'alimentation et connecte la source d'alimentation haute tension audit chemin d'alimentation.
(JA)  高電圧電源と低電圧電源をモータのコイルへの給電路に切換可能に接続する2電源切換回路と、前記2電源切換回路を制御する制御回路を有する駆動装置であって、前記制御回路は、モータの回転数が所定回転数になる電源切換時までは前記2電源切換回路をOFFにして低電圧電源のみを給電路に接続し、モータが所定回転数以上になったとき2電源切換回路をONにして前記給電路に前記高電圧電源を接続するように制御する。
