[0028] like Figure 1 to Figure 4 As shown, in one embodiment of the utility model, a high-speed linear motor with a built-in heat dissipation system is involved, including a base 1, a transmission guide rail 2, a transmission seat 3, a stator assembly 4, a mover assembly 5 and a cooling fan 6. The surface of the base 1 is provided with a sink groove 11, and positioning and mounting grooves 12 are provided on both sides of the sink groove 11. The sink groove 11 and the mounting groove are both connected along the length direction of the base 1. The stator assembly 4 is arranged in the sink groove 11, the transmission guide rail 2 is installed in the positioning and mounting groove 12, the transmission seat 3 can be slidably installed on the transmission guide rail 2, and the mover assembly 5 is installed on the transmission seat 3 and arranged opposite to the stator assembly 4; a heat dissipation portion 13 is provided on a side of the base 1 away from the sink groove 11, and the heat dissipation portion 13 is provided with a heat dissipation mounting groove 14, the cooling fan 6 is installed in the heat dissipation mounting groove 14, and the heat dissipation portion 13 is provided with heat dissipation fins 15 on both sides of the heat dissipation mounting groove 14, and the cooling fan 6 is used to blow air toward the heat dissipation fins 15. In this embodiment, a special heat dissipation part 13 is provided on the back of the base 1, in which a heat dissipation fan 6 and heat dissipation fins 15 are installed. This design can effectively dissipate the heat generated by the linear motor during operation, preventing the linear motor from being degraded or damaged due to excessive temperature. The heat dissipation fan 6 blows air toward the heat dissipation fins 15, and the wind takes away the heat, so that the linear motor can maintain a stable temperature during long-term high-load operation, thereby extending its service life.

[0029] In the above embodiment, the heat dissipation portion 13 is integrated with the back of the base 1, does not occupy additional space, and maintains the compactness of the entire linear motor. This compact design allows the linear motor to be used in a space-constrained environment, while reducing the overall volume of the linear motor and improving the integration of the system. The arrangement of the sink groove 11 and the positioning installation groove 12 on the surface of the base 1, as well as the installation method of the transmission guide rail 2, the transmission seat 3 and the mover assembly 5, constitute a stable and reliable installation structure. This structure can ensure the precise alignment between the various components of the linear motor and improve the operating stability and accuracy of the linear motor.

[0030] In the above embodiment, the heat dissipation portion 13 is provided with a heat dissipation installation groove 14 and a heat dissipation fin 15. Through these structures, the wind force generated by the heat dissipation fan 6 can be effectively guided to the heat dissipation fin 15 and the heat dissipation can be accelerated. This design can greatly improve the heat dissipation efficiency of the linear motor and ensure that the linear motor maintains good temperature control when running at high speed.

[0031] The above embodiment adopts an innovative heat dissipation solution, and achieves excellent heat dissipation effect and reliable thermal management through compact design and stable installation structure. This design can meet the needs of various high-speed and high-load industrial applications, improve the performance, reliability and service life of the linear motor, and bring new technical solutions to the field of industrial automation.

[0032] The base 1 is formed by processing 7075 aluminum alloy material. 7075 aluminum alloy is a high-strength aluminum alloy material with excellent tensile strength and compressive strength. This enables the base 1 to maintain good structural strength and rigidity under high-speed operation and high-load conditions, reduces the risk of deformation of the base 1, and ensures the stability and reliability of the linear motor.

[0033] A support platform 16 is provided on the lower surface of the base 1, and the support platform 16 is used for installing the base 1 so that the heat dissipation part 13 is suspended. In this embodiment, by providing the support platform 16, the heat dissipation part 13 of the base 1 can be suspended to better exchange heat with the external environment. This design can effectively increase the heat dissipation area of ​​the heat dissipation part 13 of the base 1 and improve the heat dissipation efficiency. The suspended setting of the heat dissipation part 13 helps to accelerate the conduction and diffusion of heat, so that the linear motor can cool down more effectively and maintain a stable operating temperature. As a part of the base 1, the support platform 16 is integrally formed with the base 1 to provide a stable installation structure. This structure can ensure the precise alignment between the base 1 and other components, and improve the stability and reliability of the entire linear motor system.

[0034] A transmission sensor 17 is installed on the outer side of the base 1, and the transmission seat 3 is provided with a transmission sensor sheet 31, and the transmission sensor sheet 31 is used to cooperate with the transmission sensor 17 to sense the transmission position of the transmission seat 3. In this embodiment, the real-time position of the transmission seat 3 can be accurately detected through the cooperation of the transmission sensor 17 and the transmission sensor sheet 31. This precise position detection helps to achieve precise positioning and high-speed operation control of the linear motor, and improve the operation accuracy and dynamic performance of the linear motor. Accurate position detection information can be fed back to the control system of the linear motor to achieve closed-loop control of the operation of the linear motor. This can ensure that the linear motor can run accurately according to the expected trajectory and speed, and improve the overall performance and reliability of the linear motor.

[0035] A heat transfer portion 111 is provided between the sink 11 and the heat dissipation portion 13, and the heat transfer portion 111 is used to transfer the heat of the stator assembly 4 toward the heat dissipation portion 13. In this embodiment, the heat transfer portion 111 serves as a special heat conduction channel, which can effectively and quickly transfer the heat generated by the stator assembly 4 to the heat dissipation portion 13. Compared with the heat conduction directly from the sink 11 to the heat dissipation portion 13, the heat transfer portion 111 provides a more efficient heat transfer path. By setting the heat transfer portion 111, the loss of heat during the conduction process can be minimized. Heat can flow directly from the stator assembly 4 to the heat dissipation portion 13 without heat loss due to detours or poor contact. This helps to improve the heat utilization efficiency of the entire heat dissipation system.

[0036] The transmission guide rail 2 includes a slide rail 21 and a slider 22 slidably mounted on the slide rail 21. The transmission guide rail 2 is mounted in the positioning and mounting groove 12, and one side of the slider 22 is connected to the transmission seat 3. In this embodiment, the guide rail structure of the slide rail 21 and the slider 22 can provide accurate positioning and guiding functions for the transmission seat 3. This guide rail design helps to ensure that the transmission seat 3 maintains a stable running track during high-speed movement, thereby improving the positioning accuracy and running stability of the linear motor.

[0037] The transmission base 3 is provided with a mounting surface 32, and the mounting surface 32 is provided with a mounting hole 33. The mounting surface 32 provides a flat surface, so that the transmission base 3 can be easily mounted on other components or equipment.

[0038] The stator assembly 4 is composed of a plurality of stator elements 41, and the plurality of stator elements 41 are continuously arranged along the length direction of the sink 11. In this embodiment, the plurality of stator elements 41 are continuously arranged along the length direction of the sink 11, which is conducive to evenly distributing the heat generated when the linear motor is working to the entire stator assembly 4. This helps to reduce the working temperature of the stator elements 41 and improve the stability and reliability of the system.

[0039] The heat dissipation mounting groove 14 is provided with guide arc surfaces 141 on both sides close to the heat dissipation fins 15. In this embodiment, the provision of the guide arc surfaces 141 can optimize the air flow around the heat dissipation fins 15. When the air flows through the heat dissipation mounting groove 14, the guide arc surfaces 141 will guide the air to flow along a predetermined path, effectively increasing the contact area between the air and the heat dissipation fins 15, thereby improving the heat dissipation efficiency. The design of the guide arc surfaces 141 helps to reduce the resistance during air flow. By guiding the air to the vicinity of the surface of the heat dissipation fins 15, the guide arc surfaces 141 can reduce the resistance loss during air flow, thereby improving the efficiency of air flow and reducing energy consumption.

[0040] The cooling fan 6 is provided with a plurality of vertical blades 61, and the blades 61 are used to blow air toward the cooling fins 15. In this embodiment, the vertical blades 61 can generate a strong airflow to effectively blow away the heat from the cooling fins 15. This airflow directly blowing toward the cooling fins 15 can greatly improve the heat dissipation efficiency and help reduce the operating temperature of the linear motor.
