Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to an iron-coreless linear motor with air cooling. Background Art

[0002] In modern industry and automation, linear motors, devices that convert electrical energy directly into mechanical energy for linear motion, are widely used in various precision positioning and transportation systems due to their high efficiency, high precision, and fast response. Traditional linear motors typically consist of a stator and a mover. The stator generates a magnetic field, while the mover generates linear motion under the influence of the magnetic field.

[0003] However, existing air-cooled ironless linear motor designs have several limitations. Due to the lack of an iron core, these motors lack sufficient heat dissipation, leading to overheating during high-power operation, which in turn limits their thrust output and sustained operation. Furthermore, traditional air-cooled ironless linear motors typically utilize an integrated air-cooling structure. While this structure provides some heat dissipation, it is difficult to manufacture and results in high manufacturing costs.

[0004] To address these issues, some researchers have attempted to improve motor design to enhance heat dissipation. For example, they have added heat sinks to the rotors or used highly thermally conductive materials to improve heat dissipation efficiency. However, these approaches often offer limited improvement and may increase the size and weight of the motor, making it unsuitable for use in space-constrained applications. Utility Model Content

[0010] In one embodiment of the present invention, a guide groove is further provided on the trough body. The guide groove is arranged parallel to the blowing groove, and the guide groove is used to guide and diffuse the cold air from the air outlet.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figure 1-3 As shown, the utility model is an air-cooled ironless linear motor, comprising:

[0028] An air-cooled ironless linear motor body comprises a stator 1 and a mover 2; the stator 1 is used to generate a magnetic field to drive the mover 2 to perform linear motion in the magnetic field inside the stator 1;

[0029] The air cooling devices 3 include two air cooling devices, which are respectively arranged on both sides of the mover 2 to increase air flow and take away heat.

[0030] The design of the air cooling device 3 not only enhances the heat dissipation capacity of the mover 2 but also minimizes the temperature difference between the stator 1 and mover 2. This excellent heat dissipation design reduces performance degradation due to overheating and ensures stable operation of the motor under high loads. The split structure design makes the connection between the stator 1 and mover 2 easy to disassemble and replace, simplifying maintenance. Users can conveniently inspect and replace the rotor without disassembling the entire motor.

[0031] The air cooling device 3 in this embodiment includes a trough body 31, an air inlet 32 ​​is provided at one end of the trough body 31, an air blowing groove 33 is provided on the side of the trough body 31 facing the mover 2, an air outlet 34 is provided on the air blowing groove 33, and the air outlet 34 is connected to the air inlet 32. After the trough body 31 and the mover 2 are installed as a whole, the air blowing groove 33 dissipates heat from the side of the mover.

[0032] Furthermore, the trough body 31 is provided with a guide groove 35, which is arranged parallel to the blowing groove 33 and is used to guide and diffuse the cold air from the air outlet 34. The guide groove 35 optimizes the airflow from the air outlet 34, ensuring that the air flows evenly within the blowing groove 33 and effectively covers the sides of the mover 2, thereby improving heat dissipation efficiency. In addition, the parallel arrangement of the guide groove 35 and the blowing groove 33 helps maintain the linear motion of the airflow and reduce air turbulence on the surface of the mover 2.

[0033] In this embodiment, the depth of the guide groove 35 is greater than the depth of the blowing groove 33. The depth of the blowing groove 33 directly affects the heat exchange efficiency between the air and the side of the mover 2. The deeper blowing groove 33 can increase the surface area of ​​the air flow, thereby improving the heat transfer efficiency. The depth of the guide groove 35 is greater than the depth of the blowing groove 33. Such a design can make the guide groove 35 act as a diffuser of the airflow, dispersing the high-speed airflow into a wider airflow, covering the side of the mover 2 in a more uniform manner, helping to ensure that the cold air is more evenly distributed on the side of the mover 2, avoiding local overheating, and improving the heat dissipation uniformity of the entire mover 2. At the same time, by designing the depth of the guide groove 35, the turbulence and eddy currents of the airflow on the surface of the mover 2 can be reduced, which helps to reduce the resistance of the airflow to the mover 2 and reduce noise.

[0034] Preferably, the air inlet 32 ​​is connected to the air source via a connecting pipe.

[0035] Furthermore, a plurality of mounting positioning holes 36 are provided side by side on both sides of the trough body 31 .

[0036] In this embodiment, the air cooling device 3 is mounted on either side of the mover 2 via mounting brackets 4. The placement of the air cooling device 3 on either side of the mover 2 increases air flow, quickly dissipating heat generated by the mover 2 during operation and improving the motor's heat dissipation capacity. The design of the mounting brackets 4 ensures a stable connection between the air cooling device 3 and the mover 2, preventing displacement or vibration of the air cooling device 3 during motor operation.

[0037] like Figure 4 As shown, the mounting base 4 is provided with a slot 41 adapted to fit the top of the mover 2, and the mounting base 4 is provided with a plurality of mounting positioning holes 42 on both sides of the slot 41. The design of the slot 41 allows for quick removal and replacement of the air cooling device 3, reducing maintenance costs.

[0038] In one embodiment of the present invention, the shape of the slot 41 is adapted to the top of the stator 1 .

[0039] In one embodiment of the present invention, the stator 1 includes a fixing plate 11, a fixing plate 2 12, a U-shaped support block 13 and a magnet 14. A plurality of magnets 14 are arranged on the inner walls of the fixing plate 11 and the fixing plate 2 12 relative to each other to generate a uniform magnetic field; the U-shaped support block 13 is arranged between the fixing plate 1 11 and the fixing plate 2 12, so that a space for accommodating the stator 1 to pass through is formed between the fixing plate 11 and the fixing plate 2 12.

[0040] Based on the air-cooled coreless linear motor with air cooling in this embodiment, a good heat dissipation design reduces the wear of the motor due to overheating, thereby extending the service life of the motor and improving the return on investment; since the heat dissipation capacity of the motor is improved, it can operate at a higher power level without worrying about overheating, thereby improving the operating efficiency of the motor. In addition, the design of the split air-cooling device 3 reduces the difficulty of processing. Compared with the traditional integrated structure, the split structure is easier to manufacture and assemble, thereby reducing production costs. At the same time, the split structure design is easy to disassemble and replace, which simplifies the maintenance and repair work of the motor and reduces maintenance costs. Improve reliability: The improvement of the motor's continuous operation capability and heat dissipation performance enhances the reliability of the motor during long-term operation and reduces the probability of failure; in addition, the design of the split air-cooling device 3 allows the motor to be easily integrated into various equipment, providing design flexibility and convenience.

[0041] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
