Embodiment Construction

[0030] In this embodiment, the stator coil 13 of the motor is filled with working fluid, such as hydraulic oil. During operation, the heat generated by easily heating elements such as winding wires and silicon steel sheets can be dissipated through oil cooling, so when working in an inflammable and explosive environment More security.

[0031] In this embodiment, the stator 1 of the motor further includes wires and a controller 15 connected to the stator coil 13 and drawn out from a hole on the shaft of the left stator 11 for controlling the operation of the motor.

[0032] In this embodiment, the outer rotor 2 of the motor further includes a distribution rotor 21 coaxially sleeved on the outside of the stator 1. The inner surface of the distribution rotor 21 has an annular wide groove and pin holes are formed on both ends.

[0033] In the example of this embodiment, the outer rotor 2 of the motor further includes permanent magnets 25, and a plurality of permanent magnets 25 a...

Abstract

The invention discloses a two-dimensional motor piston pump which is formed by combining a motor and a piston pump and comprises a two-dimensional motor and a two-dimensional piston pump, and the two-dimensional motor drives the two-dimensional piston pump to work. The two-dimensional motor can be divided into a stator and an outer rotor, the outer rotor of the motor is coaxial with the stator and arranged on the outer side of the stator, and the outer rotor of the motor serves as a piston and a flow distribution mechanism of the two-dimensional piston pump at the same time and rotates and axially moves in the working process. Partial structures of the two-dimensional motor and the two-dimensional piston pump are shared, so that the structure is more compact; the rotor of the two-dimensional motor does not need to be supported by a bearing, so that the problem that the service life of the motor is influenced by axial force is avoided; the rotation and axial movement of the rotor are converted into magnetic coupling and decoupling by using the two-dimensional motor, so that the friction is reduced, and the efficiency is improved; the motor is of a wet-type structure, heat dissipation is good, and sparks are not prone to being caused; a two-dimensional piston pump structure is used, and the volume efficiency is high.

Description

technical field [0001] The present application relates to the fields of motor technology and fluid transmission technology, in particular to a two-dimensional motor piston pump composed of a two-dimensional motor and a two-dimensional piston pump. Background technique [0002] The motor is a component that converts electrical energy into mechanical energy to provide power, and is often used as a power source for pumps. An external rotor motor is one in which the coils are on the stator and the permanent magnets are on the outer rotor. Compared with ordinary motors, the rotor of a two-dimensional motor can also move axially to a certain extent while rotating. A hydraulic pump is a hydraulic component that provides pressurized liquid in a hydraulic system. It is a conversion device that converts mechanical energy such as an electric motor or an internal combustion engine into hydraulic energy. The piston pump relies on the reciprocating motion of the piston to make the worki...
