[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-5 A slotless armature DC servo motor heat dissipation assembly includes an exhaust hole 101. A dust blocking mechanism having a dust blocking function of a fixed ring 4 is provided in the exhaust hole 101. The dust blocking mechanism includes a slide rail 5, a rotating piece 6, a fixed piece 7, and a turning handle 8. The inner wall of the exhaust hole 101 is fixedly connected to the fixed piece 7 in an annular array. The inner ring of the fixed ring 4 is fixedly connected to the rotating piece 6 in an annular array. One end of the plurality of rotating pieces 6 is fixedly connected to the turning handle 8.

[0022] It also includes a slotless armature DC servo motor 1, a dust screen 2 is provided at the front end of the housing of the slotless armature DC servo motor 1, and a dust screen 2 is provided inside the housing of the slotless armature DC servo motor 1; the design of the dust screen 2 and the dust screen 3 can filter debris in the air on the one hand, and on the other hand, have the advantage of introducing air into the interior of the slotless armature DC servo motor 1.

[0023] In this embodiment, the front end of the housing of the slotless armature DC servo motor 1 is in a cavity state, and the front end of the housing of the slotless armature DC servo motor 1 is fixedly connected to a bracket 100, on which a dustproof net 2 is distributed and installed. A dustproof net 2 3 is fixedly installed at the bottom of the housing of the slotless armature DC servo motor 1, and the width of the dustproof net 2 3 is smaller than the width of the inside of the housing of the slotless armature DC servo motor 1.

[0024] In this embodiment, the slotless armature DC servo motor 1 includes a bearing 102 , the exhaust fan blade 9 is fixedly connected to the tip of the bearing 102 , and one end of the bearing 102 is rotatably connected to the middle of the handle 8 .

[0025] In this embodiment, an exhaust hole 101 is provided at the rear end of the housing of the slotless armature DC servo motor 1. In order to better limit the fixed ring 4, the rotating plate 6 and the fixed plate 7, a slide groove 103 is provided on the exhaust hole 101. The outer ring of the fixed ring 4 is fixedly connected to the slide rail 5, and the slide rail 5 is slidably connected to the slide groove 103.

[0026] In this embodiment, in order to better fix the rotating plate 6 before and after rotation and prevent it from rotating on its own, a magnet 60 is installed on the side surface of the rotating plate 6 that contacts the fixed plate 7. The magnet 60 also plays a limiting role. When the rotating plate 6 rotates, the magnet 60 rotates on the limiting groove 70. The fixed plate 7 is provided with a limiting groove 70, and the limiting groove 70 is respectively provided with an iron block area 1 700 and an iron block area 2 701.

[0027] The use method and advantages of this utility model: When this DC motor is easy to install and fix, the working process is as follows:

[0028] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, when using the present device, before starting the slotless armature DC servo motor 1, the user can rotate the handle 8, which drives the rotating plate 6 and the fixed ring 4 to rotate. At the same time, the slide rail 5 on the rotating plate 6 slides in the slide groove 103, rotating the rotating plate 6 to a position covering the fixed plate 7. At this time, the magnet 60 is adsorbed on the iron block area 701, which prevents the rotating plate 6 and the fixed ring 4 from falling. At this time, the state is as shown in the figure of the specification. Figure 1 、 Figure 2 and Figure 4 In the state shown, after the slotless armature DC servo motor 1 is started, the bearing 102 on the slotless armature DC servo motor 1 drives the exhaust fan blades 9 to work. The rotation of the exhaust fan blades 9 allows the air outside the slotless armature DC servo motor 1 to enter the interior of the slotless armature DC servo motor 1 through the dustproof net 1 2 and the dustproof net 2 3. The exhaust fan blades 9 blow out the hot air inside the slotless armature DC servo motor 1. The setting of the exhaust fan blades 9 allows the internal circulation of the slotless armature DC servo motor 1 to enter the air, which can avoid the situation where the heat caused by the excessive rotation speed of the original parts inside the slotless armature DC servo motor 1 is difficult to be discharged, resulting in damage to the internal components of the slotless armature DC servo motor 1.

[0029] When the slotless armature DC servo motor 1 stops working, the user rotates the handle 8 to drive the rotor 6 to separate from the fixed plate 7, so that the fixed plate 7 and the rotor 6 are combined into a circle, and the rear magnet 60 rotates to the iron block area 701 and is adsorbed. At this time, the fixed plate 7 and the rotor 6 can completely cover the exhaust hole 101 to prevent debris from entering the exhaust hole 101 and affecting the normal operation of the internal components of the slotless armature DC servo motor 1, thereby achieving an effective dust-blocking effect.

[0030] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
