SMALL HYDRAULIC SYSTEM INTEGRATED WITH MOTOR AND DOUBLE ROWS PHASE DISPLACEMENT TYPE EXTERNAL PUMP AND BUILT-IN HYDRAULIC CIRCUIT

摘要

The present invention relates to a small hydraulic power generator in which a motor and a double-speed staggered gear pump are integrated and a hydraulic circuit for direct oil control is incorporated. More particularly, the present invention relates to an electric motor, comprising: a motor unit generating an electric power; A gear pump including a gear pump having an output port and receiving the electric power to generate hydraulic power; A hydraulic oil discharge port for applying the hydraulic oil by the hydraulic power to the actuator; A hydraulic pressure passage for transferring the hydraulic oil from the output port to the hydraulic oil discharge port; A pressure sensor provided on one side of the hydraulic pressure to measure a pressure with the hydraulic pressure; A power converter for converting the electric power of high RPM to low torque into a low RPM-high torque and applying the electric power to the hydraulic gear pump; and an operation for controlling the operation of the electric motor based on the hydraulic pressure measurement value And a power-control line connector enclosed in the hydraulic circuit and the power conversion section and hermetically closed to apply a driving power source and a control signal to the motor section, the hydraulic piston pump, The present invention relates to a small hydraulic power generator in which a motor including a casing unit and a double-speed stator gear pump are integrated and a hydraulic circuit for direct hydraulic control is incorporated.
