    摘要： Provided is a spool valve device capable of detecting operation abnormality of a spool without increasing the number of parts. A spool valve device includes: a housing on which a plurality of channels are formed; a spool configured to move to change connection statuses of the plurality of channels; an electric actuator including an electric motor and a linear-motion conversion mechanism, the electric motor being configured to rotate an output shaft by torque corresponding to a drive current supplied to the electric motor, the linear-motion conversion mechanism being configured to convert rotational movement of the output shaft into straight movement and apply thrust corresponding to the torque to the spool to change the position of the spool; a biasing member configured to apply biasing force to the spool against the thrust of the electric actuator; an angle detector configured to detect an angular position of the output shaft of the electric motor; a driving portion configured to drive the electric motor by controlling flow of the drive current supplied to the electric motor based on a position command input to the driving portion and the angular position detected by the angle detector; and an abnormality determining portion configured to calculate the position of the spool based on the angular position detected by the angle detector and determine presence or absence of operation abnormality of the spool.

    摘要： This electrohydraulic robot includes: a manipulator including a plurality of joints; a plurality of drive devices that are provided in a one-to-one correspondence with the plurality of joints and each move a corresponding one of the plurality of joints; and a control device that controls movement of each of the plurality of drive devices. Each of the plurality of drive devices includes: a hydraulic actuator that moves a corresponding one of the plurality of joints; a hydraulic pump that supplies a working fluid to the hydraulic actuator; and an electric motor that drives the hydraulic pump. The control device is a pump of a variable capacity type that drives the electric motor and changes the discharge capacity of the hydraulic pump.

    摘要： An electricity-oil hybrid motor 1 includes an oil-pressure motor 10 and an electric motor 30. The electricity-oil hybrid motor 1 includes a rotating shaft 11 and causes the rotating shaft 11 to rotate by supplied operating oil. The electric motor 30 includes a rotor 32 connected to the rotating shaft 11, a stator 33 provided around the rotor 32, and a housing 34 in which the rotor 32 and the stator 33 are accommodated. The rotor 32 and the housing 34 are provided so as to surround and cover a casing 17 of the oil-pressure motor 10. The housing 34 includes a rotating shaft accommodating space 51 in which the rotating shaft 11 is accommodated and a stator accommodating space 52 in which the stator is accommodated. A sealing member 39 configured to separate the accommodating spaces 51 and 52 is provided in the housing 34.
