More Information
Summary:An excavator has an electric motor (71), an inverter (20C) connected to the electric motor, and an electricity storage device (120) connected to the inverter and including a capacitor (19). While driving of an engine (11) is being suspended, the voltage of the capacitor (19) is maintained higher than a second predetermined voltage value. L'invention porte sur une excavatrice, qui a un moteur électrique (71), un onduleur (20C) connecté au moteur électrique, et un dispositif de stockage d'électricité (120) connecté à l'onduleur et comprenant un condensateur (19). Pendant que la conduite d'un moteur (11) est suspendue, la tension du condensateur (19) est maintenue supérieure à une seconde valeur de tension prédéterminée.
