SYSTÈME D'ALIMENTATION ET PROCÉDÉ POUR MOTEUR À COURANT CONTINU ENTRAÎNANT UNE POMPE HYDRAULIQUE

摘要

A power supply system can be used for an electric motor that drives a hydraulic pump in a demolition robot. The system provides a DC current from a source of power, controls and monitors the voltage level (VDCnom) of the DC current, can be activated, and supplies a pre-determined load current (IL) from the source of power to the electric motor. In order to offer improved operational availability and flexibility, the load current (IL) can be constituted by a DC current, and the electric motor can be a DC motor.
