Abstract
(EN)
The effective input current to a voltage type inverter (702) is detected by an effective value detection circuit (706), so that the rotational speed of a brushless D.C. motor (703) is detected on the basis of the cycle of a position signal outputted from a position detection circuit (704). In response to the effective input current and the motor speed, the phase of the inverter output voltage with respect to the motor counterelectromotive force is determined to maximize motor efficiency, and thus a switching instruction to the voltage type inverter (702) is generated. According to this construction, a high efficiency operation can be accomplished without increasing the cost and moreover, irrespective of a load condition, when the voltage waveform of the input to the brushless D.C. motor (703) is controlled by only the voltage type inverter in response to a position detection signal of a rotor.

Le courant d'entrée effectif d'un onduleur (702) de type tension est détecté par un circuit (706) de détection de valeur effective, si bien que la vitesse de rotation d'un moteur à courant continu sans balai est détectée sur la base du cycle d'un signal de position produit par un circuit (704) de détection de position. En réponse au courant d'entrée effectif et à la vitesse du moteur, la phase de la tension de sortie de la commutatrice par rapport à la force contre-électromotrice du moteur est déterminée pour maximiser l'efficacité du moteur. En conséquence, un ordre de commutation est produit et envoyé à l'onduleur (702) de type tension. Avec cette configuration, on peut obtenir un fonctionnement à rendement élevé sans augmentation du coût et de surcroît indépendamment de l'état de charge, lorsque la forme d'onde de tension d'entrée dans le moteur (703) à courant continu sans balai est commandée uniquement par l'onduleur de type tension en réponse à un signal de détection de position du rotor.
