Abstract

The application discloses a two-dimensional motor piston pump. The two-dimensional motor piston pump is composed of a combination of a motor and a piston pump, including a two-dimensional motor and a two-dimensional piston pump. 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 placed outside the stator. The outer rotor of the motor also acts as the piston and distribution mechanism of the two-dimensional piston pump, which rotates and moves axially during operation. Part of the structure of the two-dimensional motor and the two-dimensional piston pump is shared, which makes the structure more compact; the rotor of the two-dimensional motor does not need bearing support, which avoids the problem that the life of the motor is affected by the axial force; the two-dimensional motor is used to adjust the rotation of the rotor and the shaft The motion is converted into magnetic coupling and decoupling, which reduces friction and improves efficiency; the motor is a wet structure, which has good heat dissipation and is not easy to cause sparks; using a two-dimensional piston pump structure, the volumetric efficiency is high.

Description

technical field [0001] The present application relates to the fields of motor technology and fluid transmission technology, and in particular, to a two-dimensional motor piston pump composed of a two-dimensional motor and a two-dimensional piston pump. Background technique [0002] A 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 outer rotor motor is one in which the coils are on the stator and the permanent magnets are on the outer rotor. Compared with the ordinary motor, the rotor of the two-dimensional motor can also do a certain axial movement while rotating. A hydraulic pump is a hydraulic component that provides pressurized liquid in a hydraulic system, and is a conversion device that converts the mechanical energy of an electric motor or an internal combustion engine into hydraulic energy. The piston pump relies on the reciprocating motion of the piston, which makes the ...
