Description

Technical Field

[0001] This utility model belongs to the field of heat dissipation motor technology, and specifically relates to a rotor and a heat dissipation motor. Background Technology

[0002] With the rapid development and popularization of the drone industry, people have higher and higher requirements for the performance and speed of drones. At the same time, the power consumption of motors is increasing, and the heat generated by high-power motors is also increasing. Therefore, the demand for motor heat dissipation efficiency is also increasing.

[0003] Currently, the motor industry typically addresses motor heat dissipation by altering the size of the stator or rotor to reduce power consumption, thereby decreasing the temperature and heat generated during operation. However, reducing power consumption alone cannot meet the operational requirements of devices like drones, and assembling separate stators and rotors presents limitations and may even increase the temperature and heat generated during operation. Therefore, how to reduce the heat generated by a motor during operation without compromising power consumption requirements, thus improving motor heat dissipation efficiency, is a pressing technical challenge in the field of motor heat dissipation technology. Summary of the Invention

[0004] The main purpose of this utility model is to provide a rotor for a cooling motor and a cooling motor, aiming to solve the technical problem of how to reduce the temperature generated by the cooling motor during operation and improve the cooling efficiency of the cooling motor without affecting the power consumption requirements of the cooling motor.

[0005] This utility model is implemented as follows: a rotor for a cooling motor is provided. The rotor includes a rotor body and a rotor end cover. The rotor body is provided with multiple spokes. The inner ends of the spokes are provided with flow-guiding slopes. The rotor end cover is connected to the ends of the spokes and works in conjunction with the flow-guiding slopes to guide airflow into the cooling air passage of the cooling motor.

[0006] Furthermore, the multiple spokes are evenly distributed circumferentially on the rotor body.

[0007] Furthermore, the inclination angle of the drainage slope is between 1° and 89°.

[0008] Furthermore, the inclination angle of the drainage slope is 45°.

[0009] Furthermore, the number of spokes is 6-12.

[0010] Furthermore, an air inlet communicating with a heat dissipation duct is provided between adjacent spokes.

[0011] Furthermore, the rotor end cover is provided with multiple spikes.

[0012] This invention is implemented by providing a heat-dissipating motor, including a stator and a heat-dissipating motor rotor as described in the preceding claims, wherein a heat dissipation air passage is provided between the stator and the rotor.

[0013] Furthermore, the cooling motor also includes a base, one end of which is mounted on the base, and the rotor body is rotatably connected to the stator via a rotor shaft, screws, and bearings.

[0014] Compared with the prior art, the present invention provides a rotor and a cooling motor for a cooling motor. The cooling motor includes a stator and a rotor, with a cooling air passage provided between the stator and the rotor. It also includes a rotor body and a rotor end cover. The rotor body has multiple spokes, and the inner ends of each spoke have guiding inclined surfaces. When the rotor rotates, these guiding inclined surfaces promote gas flow, increasing the flow rate and volume of the cooling gas. The rotor end cover is connected to the outer end of the spokes and works in conjunction with the guiding inclined surfaces to guide airflow into the cooling air passage of the cooling motor, thereby increasing the gas flow rate and / or velocity entering the cooling air passage, achieving efficient self-ventilation cooling, thus reducing the heat generated by the cooling motor during operation, and ultimately improving the cooling efficiency of the cooling motor.

[0017] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] With the rapid development and popularization of the drone industry, people have higher and higher requirements for the performance and speed of drones. At the same time, the power consumption of motors is increasing, and the heat generated by high-power motors is also increasing. Therefore, the demand for motor heat dissipation efficiency is also increasing.

[0019] Currently, the motor industry typically addresses motor heat dissipation by altering the size of the stator or rotor to reduce power consumption, thereby decreasing the temperature and heat generated during operation. However, reducing power consumption alone cannot meet the operational requirements of devices like drones, and assembling separate stators and rotors presents limitations and may even increase the temperature and heat generated during operation. Therefore, how to reduce the heat generated by a motor during operation without compromising power consumption requirements, thus improving motor heat dissipation efficiency, is a pressing technical challenge in the field of motor heat dissipation technology.

[0020] Based on this, please refer to Figures 1 to 4 As shown, a preferred embodiment of the rotor of a heat dissipation motor of the present invention includes: a rotor body 1 and a rotor end cover 2. The rotor body 1 is provided with a plurality of spokes 3. The two ends of the inner side of the spokes 3 are provided with flow guiding slopes 30. The rotor end cover 2 is connected to the end of the spokes 30 and is used to work in conjunction with the flow guiding slopes 30 to guide the airflow into the heat dissipation air passage 5 of the heat dissipation motor.

[0021] Compared with the prior art, the rotor of the cooling motor of this utility model has multiple spokes on the rotor body. The inner ends of the spokes are provided with flow guiding slopes. When the rotor rotates, the flow guiding slopes promote the flow of gas, increasing the flow rate and flow of cooling gas. The rotor end cap is connected to the outer end of the spokes and works in conjunction with the flow guiding slopes to guide the airflow into the cooling air passage of the cooling motor, thereby increasing the flow rate and / or flow velocity of the gas entering the cooling air passage, realizing efficient self-ventilation and heat dissipation, thereby reducing the heat generated by the cooling motor during operation, and thus improving the heat dissipation efficiency of the cooling motor.

[0022] It should be noted that the heat dissipation duct 4 can be the gap between the rotor body 1 and the stator core 5.

[0023] It should be specifically noted that one end of the spoke 3 is installed on the rotor end cover 2, and the other end is installed on the upper end of the rotor body 1. The flow guiding slope 30 can be provided at both ends of the inner side of the spoke 3. Regardless of whether the rotor body 1 rotates clockwise or counterclockwise, the flow guiding slope 30 actively forms a self-circulating airflow channel on the inner and outer sides of the cooling motor, guiding external gas into the cooling air passage 4 of the cooling motor, thereby increasing the gas flow rate and / or velocity entering the cooling air passage 4, thereby reducing the heat generated by the cooling motor during operation, and thus improving the cooling efficiency of the cooling motor.

[0024] It should also be noted that in the above embodiments, the spokes 3 are configured as multiple sets of double spokes. In other embodiments, they can also be configured as multiple single spokes. This is not limited here.

[0025] Specifically, multiple spokes 3 are evenly distributed circumferentially on the rotor body 1.

[0026] More specifically, the number of spokes 3 is 6-12. The design of multiple spokes 3 can increase the airflow into the cooling duct of the heat dissipation motor, thereby increasing the gas flow rate and / or velocity entering the cooling duct.

[0027] In embodiments of this disclosure, the inclination angle of the drainage slope 30 is from 1° to 89°. It should be specifically noted that the inclination angle of the flow-guiding inclined surface 30 is the angle between the flow-guiding inclined surface 30 and the circumferential projection line of the rotor body 1.

[0028] Specifically, the inclination angle of the drainage slope (30) is 45°. For example... Figure 4 As stated, the included angle α is equal to 45°.

[0029] It should be specifically noted that the flow-guiding inclined surface 30 is set at a specific angle to the circumferential projection line of the rotor body 1. This conforms to the fluid dynamics setting, and when the rotor body 1 rotates, it drives the flow-guiding inclined surface 30 to rotate at high speed, which can increase the gas flow rate and / or flow velocity flowing into the heat dissipation channel 4, thereby reducing the heat generated by the cooling motor during operation and thus improving the heat dissipation efficiency of the cooling motor.

[0030] In the embodiments of this disclosure, an air inlet 31 communicating with the heat dissipation duct 4 is provided between adjacent spokes 3. This ensures smooth airflow and improves heat dissipation efficiency.

[0031] In the embodiments of this disclosure, the rotor end cover 2 is provided with a plurality of spikes 32. When the motor is mounted on external components (such as propellers, wheels, etc.), the friction with the external components can be increased, ensuring power transmission efficiency.

[0032] Please refer to Figure 5 as well as Figure 6 As shown, a preferred embodiment of the heat dissipation motor of the present invention includes a stator 5 and the aforementioned heat dissipation motor rotor, wherein a heat dissipation air passage 4 is provided between the stator 5 and the rotor body 1.

[0033] Furthermore, the cooling motor also includes a base 6, one end of the stator 5 is mounted on the base 6, and the rotor body 1 is rotatably connected to the stator 5 through the rotor shaft 10, screws 7, and bearings.

[0034] It should be noted that the specific structure of the rotor has been described in detail in the foregoing embodiments, and will not be repeated here.

[0035] Compared with the prior art, the present invention provides a heat dissipation motor, which includes a stator 5 and a rotor. A heat dissipation air passage 4 is provided between the stator 5 and the rotor. The rotor includes a rotor body 1 and a rotor end cover 2. Multiple gas guiding structures with specific angles are provided on the inner side of the rotor end cover 2. When the rotor rotates, the gas guiding structures actively form a self-circulating airflow channel on the inner and outer sides of the heat dissipation motor, guiding external gas into the heat dissipation air passage 4 of the heat dissipation motor, thereby increasing the gas flow rate and / or flow velocity entering the heat dissipation air passage 4, thereby reducing the heat generated by the heat dissipation motor during operation, and thus improving the heat dissipation efficiency of the heat dissipation motor.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
