Title:
MOTOR DIRECT-COUPLING TYPE HYDRAULIC PUMP DEVICE
Document Type and Number:
Japanese Patent JP2019206919
Kind Code:
A
Abstract:
To provide a motor direct-coupling type hydraulic pump device which is high in efficiency and low in a cost.SOLUTION: In a motor direct-coupling type hydraulic pump device, a motor 1 and a hydraulic pump 9 are integrally connected to each other, an input shaft 13 is rotationally driven by an output shaft 5, and a working fluid is sucked and discharged. The motor 1 is the synchronous reluctance motor 1 in which a permanent magnet is not used for a rotor, and an electromotive voltage is not generated. The hydraulic pump 9 is the variable capacity type vane pump 9 in which a plurality of vanes 20 are slidably inserted in a radial direction, the rotor 17 rotating together with the input shaft 13 is rotatably arranged in a pump main body 10, and a ring-shaped movable ring 21 which surrounds an external periphery of the rotor 17, and in which tips of the vanes 20 slide-contact with an internal peripheral face 21A is eccentrically and movably arranged.SELECTED DRAWING: Figure 1
