AIR COMPRESSOR AND MOTOR CONTROL DEVICE

An air compressor (1) is provided with a control section (5) which controls a motor section (4) by employing PAM control and PWM control. The control section (5) changes a voltage value, which is a condition for transition from the PWM control to the PAM control, corresponding to increase state of a...

Beschreibung
Zusammenfassung:	An air compressor (1) is provided with a control section (5) which controls a motor section (4) by employing PAM control and PWM control. The control section (5) changes a voltage value, which is a condition for transition from the PWM control to the PAM control, corresponding to increase state of a duty value of the PWM control performed just after the motor section (4) is started to be driven. Cette invention concerne un compresseur d'air (1) pourvu d'une section de commande (5) qui commande une section de moteur (4) au moyen d'une commande PAM et d'une commande PWM. La section de commande (5) modifie une valeur de tension, laquelle constitue une condition de transition d'une commande PWM vers une commande PAM, correspondant à une augmentation d'une valeur de service de la commande PWM exécutée juste après le démarrage de la section de moteur (4).
