Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This utility model provides a technical solution: a high-efficiency heat dissipation motor rotor structure, including a rotating shaft 1 and a rotor core 2. A fan blade is installed at one end of the rotating shaft 1. A limiting component 3 is installed on the surface of the rotating shaft 1. A positioning groove 4 is provided on the rear side of the rotor core 2. Multiple through holes 5 are distributed circumferentially and are provided inside the rotor core 2. They are installed inside the through holes 5 of the heat-conducting component 6. Multiple threaded holes 7 are distributed circumferentially and are provided on the front side of the rotor core 2. The threaded holes 7 are threadedly connected to fixing bolts 8. The middle part of the fixing bolts 8 is threadedly connected to the mounting plate 9. A sheath 10 is bonded to the side edge of the mounting plate 9. Multiple permanent magnets 11 are bonded to the inner side of the sheath 10.

[0020] The limiting component 3 includes two limiting protrusions 31 and a positioning ring 32. The two limiting protrusions 31 are distributed vertically and fixedly installed on the surface of the rotating shaft 1. The positioning ring 32 is fixedly installed on one end of the surface of the rotating shaft 1 and is located behind the limiting protrusions 31.

[0021] The heat-conducting component 6 includes multiple heat-conducting rods 61, which are movably installed inside the through hole 5. The size of the heat-conducting rods 61 matches that of the through hole 5. A heat-conducting plate 62 is welded to one end of each heat-conducting rod 61. The heat-conducting plate 62 is installed on one end of the surface of the rotating shaft 1 by bolts. The heat dissipation fins 63 are installed on the side of the heat-conducting plate 62 away from the heat-conducting rods 61 by bolts.

[0022] The sheath 10 is made of carbon fiber, and the permanent magnet 11 is made of samarium cobalt. Samarium cobalt has low coercivity and remanence temperature coefficient, good thermal stability, and high Curie temperature, making it very stable in low-temperature environments.

[0024] Working principle: When using this utility model, the limiting protrusion 31 on the surface of the rotating shaft 1 is aligned with the positioning groove 4 and inserted until the positioning ring 32 is engaged in the positioning groove 4. The mounting plate 9 is installed on the side of the rotor core 2 by fixing bolts 8. The heat conducting rod 61 is inserted along the through hole 5, and the heat conducting plate 62 is fixed to the rotating shaft by bolts, thus completing the rotor assembly, making the whole assembly easy to install and disassemble. The heat conducting rod 61 conducts heat out of the inside of the rotor core 2, and then transfers it to the heat dissipation fins 63 through the heat conducting plate 62, preventing the internal temperature of the rotor core from becoming too high. A fan blade is installed at one end of the rotating shaft 1. When the rotating shaft 1 rotates, it drives the fan blade to rotate, further driving airflow and improving heat dissipation efficiency. This utility model has the advantages of being easy to use and having good performance.
