Description

Technical Field

[0001] This utility model relates to a linear motor stator structure, specifically a linear motor stator structure that incorporates both water cooling and air cooling. Background Technology

[0002] With the development of economy and technology, more and more equipment manufacturers are using linear motors in high-end manufacturing machine tools to improve the processing accuracy of the equipment.

[0003] In the existing technology, due to the influence of equipment size, linear motors often alarm due to high temperature, which will affect the service life of the equipment. The stator permanent magnet cannot be affected by high temperature, otherwise it will demagnetize and lead to the scrapping of the motor stator. Utility Model Content

[0004] This invention proposes a linear motor stator structure with both water cooling and air cooling, aiming to overcome the aforementioned shortcomings of the prior art, improve the heat dissipation effect of the linear motor stator, reduce the temperature of the permanent magnet, and prevent demagnetization.

[0005] The technical solution of this utility model is a stator structure for a linear motor with both water and air cooling. The structure includes a stator core formed by stacked stator laminations, a linear guide permanent magnet mounted on the stator core, several outwardly protruding heat sinks punched on both sides of the stator laminations, and cooling water pipe mounting holes punched at the center of both sides of the stator laminations. Cooling water pipes are installed in adjacent cooling water pipe mounting holes on the stator core, and adjacent cooling water pipes are connected by water pipe joints. The end cooling water pipes are connected to an external cooling water device. During linear motor operation, water cooling is achieved by circulating cooling water, and the heat sinks on the stator surface increase the heat dissipation area, further reducing temperature. The combination of these two methods effectively improves stator heat dissipation.

[0006] Preferably, the heat sinks are arranged parallel to each other at uniform intervals in the height direction.

[0007] Preferably, the cooling water pipe mounting holes extend along the length direction of the stator laminations and are evenly spaced along the height direction of the stator laminations.

[0008] The advantages of this utility model are: reasonable structural design, which combines air self-cooling and water cooling to reduce stator temperature, effectively solves the problem of poor heat dissipation of linear motor stator, reduces the temperature of permanent magnet, and avoids demagnetization of permanent magnet.

[0013] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0014] like Figure 1-3 As shown, a stator structure for a linear motor with both water-cooled and air-cooled configurations is disclosed. The structure includes a stator core formed by stacking stator laminations 1. A linear guide permanent magnet 4 is mounted on the stator core. Several outwardly protruding heat sinks 2 are punched on both sides of the stator laminations 1, and the heat sinks 2 are evenly spaced and parallel to each other in the height direction. Cooling water pipe mounting holes 3 are also punched at the center of both sides of the stator laminations 1. The cooling water pipe mounting holes 3 extend along the length of the stator laminations 1 and are evenly spaced along the height direction of the stator laminations 1. Cooling water pipes are installed in adjacent cooling water pipe mounting holes 3 on the stator core, and adjacent cooling water pipes are connected by water pipe joints. A cooling water device is connected to the end of each cooling water pipe.

[0015] Based on the above structure, during production, heat sinks 2 and cooling water pipe mounting holes 3 are punched on the stator laminations 1. The stator laminations 1 are stacked one by one to form the required stator core. Then, the linear guide permanent magnet 4 is installed. At the same time, cooling water pipes are installed through the cooling water pipe mounting holes 3. The cooling water pipes are connected by water pipe joints. During the operation of the linear motor, cooling water can be passed through to achieve water cooling. At the same time, the heat sinks 2 on the surface of the stator can increase the heat dissipation area and achieve heat dissipation and cooling.

[0016] The specific heat dissipation working principle: During the operation of a linear motor, electrical energy and magnetic energy are converted into mechanical energy, which generates heat. The surface temperature of the motor stator rises, affecting the service life of the motor. Therefore, the stator structure is improved by adding both water cooling and air cooling structures. The flow of cooling water in the cooling water pipes can carry some of the heat from the permanent magnets of the stator to the outside. At the same time, the heat sinks 2 around the stator increase the heat dissipation area and exchange heat with the air to reduce the surface temperature of the stator. This cycle achieves a balance between heat dissipation on the stator surface and the temperature of the permanent magnets, thereby improving the heat dissipation of the linear motor, reducing the temperature rise of the motor, increasing the efficiency of the motor, and reducing energy consumption.

[0017] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0018] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
