The invention relates to a rotor splicing block assembly, 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 motors. The rotor splicing block assembly comprises a splicing block iron core, an insulation splicing block framework, a coil winding and a cooling pipeline, wherein the splicing block iron core is provided with a splicing part and a tooth part, the tooth part extends out of the splicing part along a first direction, the insulation splicing block framework sleeves the tooth part, and the coil winding is wound on the insulation splicing block framework; and the cooling pipeline is wound on the coil winding, and the cooling pipeline has a cooling inlet and a cooling outlet. The independent setting of thecooling pipeline can ensure good cooling for the corresponding splicing block iron core, the insulation splicing block framework and the coil winding. In addition, the cooling pipeline is simple to wind and process, thereby being conducive to the processing and production of the rotor splicing block assembly. Furthermore, it is facilitated to winding the cooling pipeline at the periphery of the whole circle of the coil winding, and the whole circle of the periphery of the coil winding can exchange heat with the cooling pipeline, thereby being further conducive to cooling the splicing block iron core, the insulation splicing block framework and the coil winding well.

Description

technical field [0001] The invention relates to the field of motors, in particular to a mover block assembly, a linear motor mover, a linear motor, a machine tool and a production method for a linear motor mover. Background technique [0002] In the existing linear motor, the cooling tube is wound on the coil winding of the mover or wound on the back of the mover iron core. The cooling tube extends in a serpentine shape along the distribution direction of the mover teeth. The number of cooling tubes is generally one One or two cooling pipes, when there is one cooling pipe, only one set of cooling joints needs to be installed at one end of the mover, and the cooling joints are connected with the cooling pipes; when there are two cooling pipes, one set is required at each end of the A set of cooling joints, each of the two cooling pipes is connected to a set of cooling joints. [0003] The temperature of the coolant in the cooling pipe increases gradually from the inflow sect...

AI Technical Summary

Problems solved by technology

[0003] The temperature of the coolant in the cooling pipe increases gradually from the inflow section to the outflow end, that is to say, the closer to the outflow end, the worse the cooling effect of the iron core winding, especially for linear motors with high power density and large mover volume structure , the temperature of the coolant in the cooling pipe rises quickly, and the iron core winding at the coolant outflow end cannot be cooled well, resulting in uneven cooling of the linear motor mover, which affects the normal operation of the linear motor

[0004] In addition, the way of serpentine extension prevents the cooling tube from fully surrounding the mover teeth, and the mover teeth that are not surrounded by the cooling tube cannot be cooled well, which further causes uneven cooling of the linear motor mover and affects the linearity. normal operation of the motor
