[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment

[0022] Please refer to Figures 1 - 3 As shown, this embodiment provides a non-magnetic resistance high-efficiency power brushless torque motor, including a main body frame 1. When the existing non-magnetic resistance high-efficiency power brushless torque motor works for a long time, it will generate a lot of heat. The heat generated during continuous operation cannot be effectively dissipated, which will cause the temperature of the motor to continuously rise. High temperature will accelerate the aging of the insulating materials inside the motor and the thermal fatigue of other components, which is likely to cause failures and greatly shorten the normal service life of the motor. Therefore, a number of uniformly sized ventilation holes 11 are provided on the surface of the main body frame 1. The ventilation holes 11 are designed to be inclined to guide the air flow in and out more effectively. A chute 12 is provided on the inner wall of the main body frame 1, and a heat dissipation component 2 is provided on the inner wall of the chute 12. The heat dissipation component 2 rotates in the inner cavity of the main body frame 1. A stator 3 is provided in the inner cavity of the main body frame 1, where:

[0023] The heat dissipation component 2 includes a number of rollers 23 that are adapted to slide on the surface of the chute 12. A bracket 22 is rotatably connected to the surfaces of the number of rollers 23. A fan blade 24 is fixedly connected to the top of the bracket 22. By sliding the rollers 23 on the inner wall of the chute 12, the fan blade 24 can rotate inside the main body frame 1. Since the rotation of the fan blade 24 can circulate the air inside the main body frame 1 through the ventilation holes 11, the stator 3 inside the main body frame 1 can be cooled to prevent damage to the device due to excessive temperature.

[0024] The improvement of this embodiment lies in:

[0025] Considering that when the existing non-magnetic resistance high-efficiency brushless torque motor works for a long time, it will generate a lot of heat, and the heat generated during continuous operation cannot be effectively dissipated, which will cause the temperature of the motor to rise continuously. High temperature will accelerate the aging of the insulating materials inside the motor and the thermal fatigue of other components, which is likely to lead to failures and greatly shorten the normal service life of the motor. Therefore, by opening ventilation holes 11 on the surface of the main frame 1, the inclined ventilation holes 11 can efficiently guide the air flow in and out, enhance the air circulation, provide a good channel for heat dissipation. The heat dissipation component 2 drives the fan blade 24 to rotate inside the main frame 1 by the sliding of the roller 23 in the chute 12, which actively promotes the air flow and greatly improves the heat dissipation efficiency. It can timely dissipate the heat generated by the stator 3. This active heat dissipation method is more effective than passive heat dissipation, can better protect the internal structures such as the stator 3, avoid problems such as the aging of insulating materials and the thermal fatigue of components caused by high temperature, thus effectively preventing failures and greatly extending the normal service life of the motor, ensuring the long-term stable and reliable operation of the motor.

[0026] In order to enable the roller 23 to move on the inner wall of the chute 12, so that the fan blade 24 rotates inside the main frame 1, power needs to be provided to the roller 23. Therefore, a rotating shaft 31 is rotatably connected to the bottom of the stator 3, and a turntable 21 is fixedly sleeved on the upper surface of the rotating shaft 31. The surface of the turntable 21 is fixedly connected to the bracket 22. By energizing the stator 3, the rotor inside the stator 3 rotates, thereby driving the rotating shaft 31 to rotate. By the rotation of the rotating shaft 31, the turntable 21 can be rotated, and by the rotation of the turntable 21, the fan blade 24 can be rotated.

[0027] In order to fix the stator 3 inside the main frame 1, a support point needs to be provided for the stator 3. Therefore, a fixing frame 140 is fixedly sleeved on the surface of the stator 3, and a support frame 14 is fixedly connected to the surface of the fixing frame 140. The surface of the support frame 14 is fixedly connected to the inner wall of the main frame 1. A groove is provided on the surface of the support frame 14 for the air flow generated when the fan blade 24 rotates to pass through. By fixedly connecting the support frame 14 to the inner wall of the main frame 1, the fixing frame 140 connected to the support frame 14 can fix the stator 3.

[0028] In order to prevent the dust outside the main frame 1 from entering the inside of the main frame 1 during operation, end caps 13 are firmly connected to both ends of the main frame 1 respectively. Its function is to protect the structural bodies inside the main frame 1. The lower surface of the rotating shaft 31 extends out of the inside of the end cap 13. By sealing the top and bottom of the main frame 1 with the end caps 13, the internal structure of the main frame 1 can be protected and dust can be prevented from entering.

[0029] In order to enable the fan blade 24 to more effectively conduct the heat generated by the stator 3 during rotation, three silicone thermal conductive rings 32 are fixedly connected to the surface of the stator 3. The three silicone thermal conductive rings 32 are evenly distributed and used to absorb the heat generated when the stator 3 works. By fitting the silicone thermal conductive rings 32 on the surface of the stator 3, the heat absorbed by the silicone thermal conductive rings 32 can be conducted out when the fan blade 24 rotates.

[0030] When the brushless torque motor with high efficiency and no magnetic resistance of the present invention is specifically used, the rotor inside the stator 3 rotates by energizing the stator 3, thereby driving the rotation of the rotating shaft 31. The rotation of the rotating shaft 31 can cause the rotation of the turntable 21. The rotation of the turntable 21 can cause the rotation of the bracket 22. The rotation of the bracket 22 can cause the roller 23 to slide on the inner wall of the chute 12. Then, the fan blade 24 connected to the bracket 22 rotates inside the main body frame 1, and the heat generated when the stator 3 works can be conducted out of the main body frame 1 through the ventilation holes 11 formed on the surface of the main body frame 1, realizing the cooling of the stator 3.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present invention and are not used to limit the present invention.
