[0019] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0020] For example, Figure 1 - Figure 3As shown, a heat-dissipating motor rotor includes a rotor body 1 and a rotor shaft 2. Both the rotor body 1 and rotor shaft 2 are existing technologies, and the rotor body 1 and rotor shaft 2 are fixedly connected, allowing the rotor body 1 to rotate and drive the rotor shaft 2 to rotate. A gear 3 is fixed to the outer surface of the rotor shaft 2, allowing the rotor shaft 2 to rotate relative to the motor housing and drive the gear 3 to rotate. A support frame 4 is rotatably mounted at the end of the gear 3 away from the rotor body 1. The support frame 4 is fixed to the inner wall of the motor housing, preventing the support frame 4 from rotating when the rotor shaft 2 rotates. The gear 3 is also fixed with an impeller 5 near the rotor body 1. The impeller 5 is existing technology, which allows the gear 3 to drive the impeller 5 to rotate when it rotates. Then the impeller 5 blows the outside air towards the rotor body 1 to cool the rotor body 1. The support frame 4 is also provided with an exhaust assembly 6 near the rotor body 1. The support frame 4 is also fixed with a filter screen (not shown in the figure) away from the rotor body 1 to prevent debris and dust from entering the rotor body 1 during motor operation, thereby causing damage to the rotor body 1 and extending the service life of the motor.

[0021] like Figure 4 As shown, the exhaust assembly 6 includes an internal gear ring 11 rotatably connected to a support frame 4. The internal gear ring 11 is connected to gear 3 via gear 2 12. Gear 2 12 is rotatably mounted on the end of the support frame 4 near the rotor body 1, and gear 2 12 meshes with both the internal gear ring 11 and gear 3, so that when gear 3 rotates, it can drive the internal gear ring 11 to rotate. An impeller 2 13 is also fixed to the end of the internal gear ring 11 near the rotor body 1. Impeller 2 13 can blow out the air inside the motor. At the same time, due to the design of impeller 5 blowing external air towards the rotor body 1, impeller 2 13 can discharge the air drawn in by impeller 5. A retaining ring 7 is also provided at the end of the support frame 4 near the rotor body 1. The retaining ring 7 is used to separate impeller 5 from impeller 2 13, which can prevent the air blown towards the rotor body 1 by impeller 5 from being sucked out by impeller 2 13, thus failing to provide good heat dissipation for the rotor body 1 and affecting the performance of the device.

[0022] The specific implementation of the embodiment is: in the working process of the motor rotor, the rotor body 1 is fixedly connected with the gear one 3, and then drives the impeller one 5 to rotate, the impeller one 5 blows air to the rotor body 1 when rotating, so that the heat dissipation effect of the rotor body 1 is achieved, and meanwhile, the gear one 3 drives the impeller two 13 to rotate through the inner gear ring 11 and the gear two 12 when rotating, the impeller two 13 can extract the air in the motor shell (since the motor shell needs to seal the rotor body 1, if the impeller two 13 does not extract the air in the motor shell, the air will flow out from between the impeller one 5, thereby reducing the heat dissipation effect), the impeller two 13 extracts the hot air, which can promote the cold and hot circulation in the motor shell and improve the heat dissipation effect of the motor rotor.

[0023] It should be noted that the specific installation method of the rotor body 1, the rotor shaft 2 and the impeller, the circuit connection mode and the control method all belong to the conventional design, and the utility model does not make detailed elaboration.

[0024] The basic principle and main features of the utility model and the advantages of the utility model are shown and described. It should be understood by those skilled in the art that the utility model is not limited by the above-mentioned embodiments, and the above-mentioned embodiments and the description in the specification are only to illustrate the principle of the utility model, and various changes and improvements can be made to the utility model without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed.
