Cooling assembly of linear motor rotor, linear motor rotor, linear motor and machine tool

Abstract

The invention provides a linear motor rotor, a linear motor rotor, a linear motor, a machine tool and a production method of the linear motor rotor, and relates to the field of the motor. The coolingassembly of the linear motor rotor comprises a cooling pipe group which comprises a first cooling pipeline and a second cooling pipeline. The first cooling pipeline is provided with a first winding section. The second cooling pipeline is provided with a second winding section. The first winding section and the second winding section serpentinely extend along a first direction. The first cooling pipeline and the second cooling pipeline are distributed along a third direction. The first direction and the third direction are perpendicular. The projection of the first winding section and the projection of the second winding section form a plurality of shadow rings distributed along the first direction through enclosing according to the projection along the third direction so that the cooling effect and the cooling uniformity of the linear motor rotor can be improved and the operation performance of the linear motor rotor can be improved.

Description

technical field [0001] The invention relates to the field of motors, in particular to a linear motor mover, a linear motor mover, a linear motor and a machine tool. Background technique [0002] Existing linear motors such as figure 1 As shown, the cooling pipeline of the linear motor mover has a winding section 104 extending in a serpentine shape. The winding section 104 of the cooling pipeline is sequentially wound on each coil winding 103 of the mover along the X-axis direction. Coolant is used to cool the linear motor mover. [0003] Each coil winding 103 is surrounded by a U-shaped pipe section with an opening of the winding section 104 towards the Y-axis direction (positive or negative), and the coil winding 103 is cooled by the U-shaped pipe section, but the coil winding 103 The side wall corresponding to the U-shaped opening cannot be covered by the U-shaped pipe section, that is, each coil winding 103 has a side wall facing the Y-axis direction that cannot be cove...

[0003] Each coil winding 103 is surrounded by a U-shaped pipe section with an opening of the winding section 104 towards the Y-axis direction (positive or negative), and the coil winding 103 is cooled by the U-shaped pipe section, but the coil winding 103 The side wall corresponding to the U-shaped opening cannot be covered by the U-shaped pipe section, that is, each coil winding 103 has a side wall facing the Y-axis direction that cannot be covered by the winding section 104, and the coil winding 103 cannot be covered by the winding section 104 The area of ​​the winding section 104 is so large that it cannot be cooled by the surrounding winding section 104, resulting in that the area of ​​the coil winding 103 that is not covered by the winding section 104 cannot be well cooled, resulting in poor cooling of the linear motor mover part area, resulting in a straight line There is obvious uneven cooling of the motor mover, which affects the normal operation of the linear motor
