In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0019] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0020] See also Figures 1 to 10 A high-speed, energy-saving and easy-to-maintain DC brushless motor, the embodiment of which comprises a motor body 1 for DC brushless operation, the outer periphery of the motor body 1 is detachably connected with two easy-to-maintain motor housings 2 by bolts, an air leakage and working channel is provided at the output shaft position of the motor body 1, and a noise reduction box 3 is provided on the outer periphery of the two motor housings 2; One side of the noise reduction box 3 is rotatably connected to a box door 4, and the box door 4 is fixedly connected to the noise reduction box 3 by a lock. The inner cavity of the noise reduction box 3 is provided with a plurality of sound-absorbing panels 5. The number of the sound-absorbing panels 5 is set to six, and the lengths are not uniform, so as to increase the noise processing area. The side of the sound-absorbing panel 5 is connected to a sound-absorbing frame 6, and the inner wall of the sound-absorbing frame 6 is connected to a grille-shaped sound-absorbing panel 7. The side of the sound-absorbing panel 7 close to the sound-absorbing frame 6 is connected to a plurality of corrugated sound-absorbing wave panels 8, and the side of the sound-absorbing panel 5 away from the sound-absorbing frame 6 is connected to a movable panel 9. The inner wall of the noise reduction box 3 and the side of the box door 4 are fixedly connected with a hollow panel 10 adapted to the movable panel 9. A spring 11 with telescopic ability is connected between the plate 9 and the noise reduction box 3 and the box door 4. A storage groove is opened on the inner wall of the hollow plate 10. The inner wall of the storage groove is bonded with an elastic rubber pad 12 for resisting the movable plate 9. When working, the sound-absorbing plate 5 can block and absorb and reduce noise. The blocking of the sound-absorbing frame 6 reduces the noise near the sound-absorbing plate 5 from propagating toward the periphery. The noise near the sound-absorbing plate 5 will also be further silenced by the sound-absorbing wave plate 8 and the sound-absorbing plate 7. The back and forth movement of the movable plate 9 consumes part of the energy by the rubber pad 12. The noise reduction box 3 can isolate noise and reduce the possibility of noise propagation. The outer periphery of the sound absorbing board 5 , the outer periphery of the sound absorbing frame 6 and the inner wall of the noise reduction box 3 are all bonded with sound absorbing cotton for sound reduction.

[0021] In order to dissipate heat, fans 14 for ventilation and heat dissipation are embedded in the sides of the noise reduction box 3 and the motor housing 2. The inner wall of the motor housing 2 is connected to a plurality of heat-conducting fins for supporting the motor body 1. The width of the heat-conducting fins is not very wide to ensure the flow of air. A ventilation channel is opened on the periphery of the heat-conducting fins. The two symmetrically arranged sides of the noise reduction box 3 are connected to S-shaped ventilation pipes 15, and the ventilation pipes 15 on one side are arranged corresponding to the position of the fan 14. When heat dissipation is required, the fan 14 of the motor housing 2 is turned on for blowing, which accelerates the air near the motor body 1 to exhaust from the vicinity of the output shaft of the motor body 1 to achieve heat dissipation. The operation of the fan 14 of the noise reduction box 3 accelerates the flow of air in the noise reduction box 3 to achieve further heat dissipation.

[0022] In order to reduce the propagation of noise, the inner wall of the ventilation pipe 15 is connected with a plurality of staggered sound baffles 16. The S-shaped design of the ventilation pipe 15 reduces the possibility of noise propagation. The plurality of staggered sound baffles 16 in the ventilation pipe 15 can also reduce the propagation of noise. The outer periphery of the end of the ventilation pipe 15 is provided with an external thread. The outer periphery of the ventilation pipe 15 is threadedly connected with a threaded pipe 17. The inner wall of the threaded pipe 17 is connected with a dustproof net 18 for filtering air. During the ventilation and heat dissipation process, the dustproof net 18 can filter the air.

[0023] In order to improve stability, the output shaft of the motor body 1 is connected to a rotating rod 19 through a coupling, and the rotating rod 19 is connected to the designated structure and equipment that needs to work. The motor body 1 is turned on to work, and the side of the noise reduction box 3 and the side of one of the sound absorbing panels 5 are provided with circular channels for the rotating rod 19 to pass through. The outer periphery of the motor housing 2 is detachably connected with multiple mounting plates 20, and the mounting plates 20 penetrate the sound absorbing panels 5 and are also detachably connected to the noise reduction box 3. The inner cavity of the circular channel is provided with a stabilizing tube 21 for high-speed and energy-saving rotation of the rotating rod 19, and the outer periphery of the stabilizing tube 21 is connected with a stabilizing tube 21. The fixed ring plate 22 and the stabilizing ring plate 22 are connected and fixed to the noise reduction box 3 by multiple bolts. A combination pipe 23 of the same size is arranged on one side of the stabilizing tube 21. The outer periphery of the combination pipe 23 is fixedly connected with a sleeve 24, which can reduce the air intake and realize high-speed energy-saving rotation. The outer periphery of the sleeve 24 is threadedly connected with multiple combination bolts for combination and fixing. The outer peripheries of the combination pipe 23 and the stabilizing tube 21 are provided with limiting channels for the combination bolts to pass through. The rotating rod 19 of appropriate length is selected, and the stabilizing tube 21 and a specified number of combination pipes 23 can be selected according to the length of the rotating rod 19, and then fixed.

[0024] In order to adjust the tilt angle, an installation frame 25 is provided on the outer periphery of the noise reduction box 3. The installation frame 25 is rotatably connected to the noise reduction box 3 through a rotating shaft. A plurality of installation channels for installation are provided on the outer periphery of the installation frame 25. A plurality of limit electric push rods 26 for adjusting the tilt angle of the noise reduction box 3 are installed on the inner wall of the installation frame 25. The moving parts of the plurality of limit electric push rods 26 are fixedly connected with a tightening ball 27 for resisting the noise reduction box 3. The outer periphery of the noise reduction box 3 and the outer periphery of the tightening ball 27 are both provided with anti-slip grooves. The extension and retraction degree of the limit electric push rod 26 is adjusted from one side. The subsequent limit electric push rods 26 are gradually adjusted to change the tilt angle of the noise reduction box 3 and ensure the stability of the noise reduction box 3.

[0025] The motor body 1, the fan 14, and the limit electric push rod 26 are all set according to the prior art. The working principle, size and model are irrelevant to the function of the present application, so they are not described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0026] How it works The high-speed, energy-saving and easy-to-maintain DC brushless motor selects a rotating rod 19 of appropriate length, and can select a stabilizing tube 21 and a specified number of combined tubes 23 according to the length of the rotating rod 19 and fix them, and then adjust the extension degree of the limit electric push rod 26 from one side to change the inclination angle of the noise reduction box 3, and then connect the rotating rod 19 with the specified structure and equipment that needs to work, and start the motor body 1 to work. When working, the sound-absorbing plate 5 can block and absorb and reduce noise. The sound-absorbing frame 6 blocks and reduces the noise near the sound-absorbing plate 5 from propagating toward the periphery. The noise near the sound-absorbing plate 5 will also be further silenced by the silencer wave plate 8 and the silencer plate 7. The movable plate 9 moves back and forth, and part of the energy will be consumed by the rubber pad 12. The noise reduction box 3 can isolate noise and reduce the possibility of noise propagation. When heat dissipation is required, the fan 14 of the motor housing 2 is turned on to blow air, accelerating the air near the motor body 1 to discharge from the vicinity of the output shaft of the motor body 1 to achieve heat dissipation. The fan 14 of the noise reduction box 3 works to accelerate the flow of air in the noise reduction box 3 to achieve further heat dissipation. During the ventilation and heat dissipation process, the dustproof net 18 can filter the air.
