| description | Methods and apparatus for open loop startup of a three-phase motor that reduces acoustic noise. During rotor alignment of the motor, there is a maximum level for a phase current to the motor. After the rotor alignment, open loop motor startup is performed during which the phase current has a first slope. At a selected time, such as when a frequency of the phase current reaches a first threshold, the phase current transitions to a second slope.
L'invention concerne des procédés et un appareil pour le démarrage en boucle ouverte d'un moteur triphasé permettant de réduire le bruit acoustique. Pendant l'alignement du rotor du moteur, on observe un niveau maximal pour un courant de phase vers le moteur. Après l'alignement du rotor, le démarrage du moteur en boucle ouverte est effectué, au cours duquel le courant de phase a une première pente. A un moment choisi, tel que lorsqu'une fréquence du courant de phase atteint un premier seuil, le courant de phase passe vers une seconde pente. |
