A MOTOR DRIVEN HYDRAULIC SYSTEM WITH TRANSMISSION
The present invention relates to an electro-hydraulic system. Specifically, according to the present invention, in the hydraulic system which obtains a hydraulic oil by driving a hydraulic pump using a driving force of an electric motor, a transmission is provided between the electric motor and the hydraulic pump to maximize efficiency of the hydraulic system. Specifically, in the electro-hydraulic system operated by the electric motor driven by a battery power, the electro-hydraulic system of the present invention comprises: a battery; the electric motor driven by a current supplied from the battery; an inverter which controls a rotation speed of the electric motor; and the transmission whose input terminal is directly connected to a rotation shaft of the electric motor; and the hydraulic pump directly connected to an output terminal of the transmission.
