Embodiment Construction

[0030] Below in conjunction with embodiment the present invention is described in further detail:

[0031] This embodiment relates to an inner curve motor with a three-phase winding and a magnetized cylinder 3, such as figure 1 , figure 2 As shown, it includes a first end cover 1, a second end cover 2, a cylinder body 3, a stator 4, a coil 5 and a plunger 6, and a stator 4 is connected between the first end cover 1 and the second end cover 2 by bolts, The cylinder body 3 is located in the inner cavity of the stator 4 .

[0032] Specifically, asfigure 1 and combine figure 2 with Image 6 As shown, the first end cover 1 is a rotating body, which includes a disc in contact with the cylinder body 3 and a central shaft, and the disc is provided with an oil inlet 101 and an oil outlet 102 passing through the disc, and, on the disc There are also several flow distribution windows 103 on the inner side of the disk. In addition, two annular oil grooves 104 with different diameter...

Abstract

The invention discloses an inner curve motor with a three-phase winding and a magnetized cylinder, comprising a first end cover, a second end cover, a stator arranged between the first end cover and the second end cover, a rotatable hinge The cylinder inside the stator, the flow distribution device and the plunger arranged on the cylinder, the inner wall of the stator is provided with multiple groups of winding posts distributed along the inner wall circumferential direction, and the winding posts are wound with three-phase alternating current The outer peripheral surface of the cylinder is provided with a number of slots at equal intervals along the circumference of the cylinder, and magnetic poles are clamped in the slots. The invention can improve the working life of the motor, and at the same time, the hydraulic system and the electromagnetic system are used to jointly provide the torque, so as to effectively increase the output torque of the motor to drive high-torque loads.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an inner curve motor with a three-phase winding and a magnetized cylinder. Background technique [0002] The inner curve radial piston motor is a multi-action low-speed high-torque hydraulic motor. In the process of each revolution, each plunger reciprocates along the curved guide rail many times. It has high power per unit mass and small volume. , Hydraulic radial force balance, high efficiency and a series of advantages. However, in some occasions, the inner curve radial motor also has insufficient output torque to drive the load to rotate. Therefore, an inner curve hydraulic motor with three-phase windings and a magnetized cylinder is proposed. [0003] The patent (CN101709685A) discloses a radial plunger type multi-action inner curve hydraulic motor, which is a kind of hydraulic equipment mainly suitable for harsh working environments such as furnace fronts. It is mainly comp...
