Description

Technical Field

[0001] This utility model relates to the field of disc motor technology, specifically to a heat-dissipating disc motor stator structure. Background Technology

[0002] Disc motors, also known as axial field motors, have an internal magnetic field that is oriented axially. Because axial field motors are generally flat, they are called disc motors. Traditional stators often use a solid iron core stacked structure, resulting in a single heat dissipation path. Heat easily accumulates in the windings, leading to excessive temperature rise and affecting the motor's lifespan and stability. Utility Model Content

The iron core and the windings form an iron core winding. The stator support includes a base circle and multiple support portions. The support portions extend outward from the periphery of the base circle. The iron core windings are located between the support portions. The innovation lies in: a heat-conducting component is disposed between the stator support and the shell. The heat-conducting component includes a heat-conducting ring. Multiple heat-dissipating fins are arranged in a ring array on the outer side of the heat-conducting ring, and multiple heat-conducting plates are arranged on the inner side of the heat-conducting ring. The support portion has an installation groove, and the heat-conducting plates correspond one-to-one with the installation grooves, and the heat-conducting plates are embedded in the installation grooves.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0017] See Figure 1-3 A heat-dissipating disc motor stator structure includes a housing 1, a stator support 2, an iron core 3, and a winding 4 disposed on the surface of the iron core. The iron core and the winding form an iron core winding. The stator support 2 includes a base circle and multiple support portions 21. The support portions 21 extend outward from the periphery of the base circle. The iron core winding is located between the support portions 21. A heat-conducting component 5 is disposed between the stator support 2 and the housing 1. The heat-conducting component 5 includes a heat-conducting ring 51. Multiple heat dissipation fins 52 are arranged in an annular array on the outer side of the heat-conducting ring 51, and multiple heat-conducting plates 53 are arranged on the inner side of the heat-conducting ring 51. The support portion 21 has a mounting groove 22. The heat-conducting plates 53 correspond one-to-one with the mounting groove 22 and are embedded in the mounting groove 22. Specifically, the heat-conducting plate 53 is in intermittent contact with the iron core winding, which means it conducts heat on the stator support 2. The heat-conducting ring 51 is in direct contact with the iron core winding, which means it conducts heat generated by the iron core winding. The heat dissipation fins 52 conduct heat quickly to the outer shell, so that the heat can be dissipated in time through the outer shell, thereby improving the heat dissipation efficiency. On the other hand, it improves the heat dissipation efficiency of the heat-conducting component 5.

[0018] In this embodiment, the heat-conducting component 5 is integrally formed, which improves the overall rigidity and extends the service life.

[0019] In this embodiment, the heat-conducting component 5 is made of copper or thermally conductive ceramic to improve heat conduction efficiency. Other materials with high thermal conductivity can also be selected to achieve high-efficiency heat transfer to the iron core winding.

[0020] In this embodiment, the gap between the stator support 2 and the core winding is filled with potting compound. The potting compound has good heat dissipation properties, which enhances heat conduction and facilitates heat dissipation. Furthermore, the potting compound can be used to fix the core winding, reducing the need for screws.

[0021] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
