Two vertical slots are formed on the lower side of the vertical plate, and the two vertical slots are slidably connected to the outer sides of the two vertical shafts. A spring I is fixedly connected to the lower side of the horizontal plate, and a counterweight is fixedly connected to the lower end of the spring I.

[0024] like Figure 1-8 As shown, this example can achieve the effect of preventing damage caused by vibrations generated when the motor is working.
[0025] The motor includes a housing 101, inside which two symmetrical semi-circular magnetic rings are fixedly connected. An output shaft 104 is rotatably connected inside the housing 101, positioned between the two magnetic rings. A wire is wound around the center of the output shaft 104. A commutator is located at the bottom of the housing 101. Two horizontal shafts 103 are fixedly connected to the upper side of the housing 101, and two vertical shafts 102 are fixedly connected to the lower side of the housing 101. The motor also includes a horizontal plate 201 and a vertical plate 301. Two horizontal grooves 202 are formed on the upper side of the horizontal plate 201, and these grooves are slidably connected to the outer sides of the two horizontal shafts 103. Two vertical grooves 302 are formed on the lower side of the vertical plate 301. Two longitudinal grooves 302 are slidably connected to the outside of two longitudinal shafts 102 respectively. A spring I 203 is fixedly connected to the lower side of the horizontal plate 201. A counterweight 204 is fixedly connected to the lower end of the spring I 203. A limit tube 304 is fixedly connected to the upper side of the longitudinal plate 301. The counterweight 204 is nested inside the limit tube 304. When alternating current passes through the conductor, a rotating magnetic field is generated. The current direction is changed through the action of the commutator. The rotating magnetic field interacts with the fixed magnetic field generated by the magnetic ring. Since the magnetic ring is fixed, the rotating magnetic field will generate a magnetoelectric torque on the output shaft 104, thereby causing the output shaft 104 to rotate, thus realizing the effect of the motor converting electrical energy into mechanical energy.
[0026] The vibration generated during motor operation causes the housing 101 to move longitudinally and laterally, which in turn drives the longitudinal shaft 102 and the transverse shaft 103 to move. Since the transverse groove 202 is slidably connected to the outside of the transverse shaft 103, when the transverse shaft 103 moves, the transverse groove 202 drives the transverse plate 201 to move longitudinally. The vibration is then transmitted to the counterweight 204 via the spring I 203. Because the counterweight 204 has a large mass, it can block the transmission of vibration. Simultaneously, the spring I 203 stabilizes the transverse plate 201, thus stabilizing it. The transverse groove 202 and the transverse shaft 103 further impede the longitudinal movement of the housing 101. Since the longitudinal groove 302 is slidably connected to the outside of the longitudinal shaft 102... Furthermore, when the longitudinal shaft 102 moves, it drives the longitudinal plate 301 to move laterally through the longitudinal groove 302, which in turn drives the limiting tube 304 to move laterally. This transmits the lateral vibration to the counterweight 204, which then blocks the movement of the limiting tube 304, thereby stabilizing the longitudinal plate 301 and maintaining its stability. The longitudinal groove 302 and the longitudinal shaft 102 further impede the lateral movement of the housing 101. Through the above process, the housing 101 is prevented from moving laterally and longitudinally, thus stabilizing the housing 101, reducing its vibration, maintaining its stability, and preventing damage caused by vibrations generated during motor operation.
[0027] like Figure 1-8 As shown, this example can achieve the effect of preventing the motor from vibrating in the vertical direction.
[0028] Since the limiting tube 304 in the motor is made of rubber, when the motor vibrates vertically, the vertical vibration is transmitted to the longitudinal plate 301 through the housing 101, which in turn drives the limiting tube 304 to move up and down. Since the counterweight 204 is nested inside the limiting tube 304, the up and down movement of the limiting tube 304 will push the counterweight 204 to move. However, since the counterweight 204 has a large mass and the limiting tube 304 is made of soft rubber, the vibration transmitted to the counterweight 204 is buffered, thus hindering the occurrence of vibration and stabilizing the housing 101, thereby achieving the effect of preventing the motor from vibrating vertically.
[0029] like Figure 1-8 As shown, this example can achieve the effect of increasing the service life of the motor.
[0030] Because a spring II 303 is fixedly connected to the upper side of the longitudinal plate 301 in the motor, and a convex plate 305 is fixedly connected to the upper end of the spring II 303, the upper side of the convex plate 305 is integrally formed into an arc surface, and an arc-shaped sliding groove 205 is opened on the lower side of the counterweight 204, and the convex plate 305 is slidably connected in the sliding groove 205; the weight of the counterweight 204 itself pulls the spring I 203 downward, and at the same time squeezes the convex plate 305, thereby squeezing the spring II 303. Thus, the spring II 303 and the spring I 203 support the counterweight 204 at the same time, reducing the stress borne by the spring I 203 and the spring II 303, thereby improving the service life of the spring I 203 and the spring II 303, and thus achieving the effect of improving the service life of the motor.
[0031] When the counterweight 204 moves, it drives the slide 205 to move. The spring II 303 pushes the convex plate 305 upward, and the convex plate 305 is pressed into the inside of the slide 205. The convex plate 305 is pressed into the center of the slide 205. When the position of the counterweight 204 shifts, the convex plate 305 and the slide 205 slide relative to each other. At this time, the convex plate 305 is pressed by the edge of the slide 205, which increases the elastic force of the spring II 303 and pushes the convex plate 305 upward, so that the convex plate 305 slides back into the center of the slide 205. Then, the slide 205 drives the counterweight 204 to move back to its original position, thus keeping the position of the counterweight 204 fixed and achieving the effect of stabilizing the counterweight 204.
[0032] like Figure 1-2 As shown in Figure 5, this example can achieve the effect of reducing motor noise.
[0033] Because two sound-insulating cotton 207s are glued between the horizontal plate 201 and the vertical plate 301 in the motor; when the output shaft 104 in the motor rotates, noise will be generated, and the sound-insulating cotton 207s will buffer and cancel the noise, thereby reducing the noise generated when the motor is working, and thus achieving the effect of reducing motor noise.
[0034] like Figure 1-4 As shown, this example can prevent the motor from overheating.
[0035] Since the housing 101 of the motor has an air inlet 107 on one side and an air outlet 108 on the other side, when the output shaft 104 of the motor rotates, some electrical energy is lost as heat in the housing 101, thereby increasing the temperature inside the housing 101. The high-temperature gas inside the housing 101 is discharged through the air outlet 108, while the low-temperature gas from the outside is drawn into the housing 101 through the air inlet 107, realizing unidirectional temperature flow, thereby keeping the temperature inside the housing 101 low, and thus preventing the motor from overheating.
[0036] like Figure 1-4 As shown in Figure 9, this example can improve the heat dissipation capacity of the motor.
[0037] Because a partition plate 401 is fixedly connected inside the housing 101 of the motor, a fixing plate I 402 is fixedly connected to one side of the partition plate 401, and a fixing plate II 403 is fixedly connected to the other side of the partition plate 401. Flexible sealing sheets 404 are fixedly connected to the inner side of the fixing plate I 402 and the outer side of the fixing plate II 403. The fixing plate I 402 is fixedly connected to the inner side of the air inlet window 107, and the fixing plate II 403 is fixedly connected to the inner side of the air outlet window 108. When the high-temperature gas inside the housing 101 flows outward, it pushes the sealing sheet 404 on the inner side of the fixing plate I 402 to stick to the fixing plate I 402, thereby closing the air inlet window 107. At the same time, it pushes the sealing sheet 404 on the outer side of the fixing plate II 403 to stick to the fixing plate II 403. 3. Separation: The gas inside the housing 101 is discharged through the air outlet 108. When the low-temperature gas from the outside enters the housing 101, it pushes the sealing sheet 404 on the inner side of the fixing plate I 402 to separate from the fixing plate I 402, thereby opening the air inlet 107 and allowing the low-temperature gas to enter through the air inlet 107. At the same time, the sealing sheet 404 on the outer side of the fixing plate II 403 is attached to the outer side of the fixing plate II 403, thereby closing the air outlet 108. This maintains the unidirectional flow of low-temperature gas and high-temperature gas inside the housing 101, preventing the high-temperature gas from mixing with the low-temperature gas and being discharged, which would reduce the cooling and heat dissipation efficiency and thus improve the heat dissipation capacity of the motor.
[0038] like Figure 1-4 As shown in Figure 9, this example can achieve the effect of preventing foreign objects from entering the motor.
[0039] Because multiple ventilation openings 405 are provided between the partition 401 and the fixed plate I 402 in the motor; the partition 401 blocks the gas entering the housing 101, so that the gas passes through the ventilation openings 405 before entering the housing 101, thereby filtering impurities carried in the air and thus preventing debris from entering the motor.
[0040] like Figure 1-4 As shown in Figure 9, this example can achieve the effect of further protecting the motor.
[0041] Because a protective plate 106 is fixed inside the housing 101 of the motor, and the protective plate 106 has multiple small holes; the multiple small holes on the protective plate 106 adsorb the iron filings from the wear of the components inside the housing 101, thereby preventing the iron filings from further damaging the motor, and thus achieving the effect of further protecting the motor.
[0042] like Figure 1-7 As shown in Figures 9-10, this example can achieve the effect of driving gas flow.
[0043] Because a sliding plate 501 is slidably connected inside the housing 101 of the motor, and the sliding plate 501 is positioned between the horizontal plate 201 and the protective plate 106; when the sliding plate 501 is slid outward, the distance between the sliding plate 501 and the housing 101 decreases, and the space between the sliding plate 501 and the housing 101 decreases, resulting in an increase in air pressure between the sliding plate 501 and the housing 101, which in turn pushes the sealing plate 404 on the outside of the fixing plate II 403 to separate from the fixing plate II 403, thereby opening the air outlet 108 and venting the gas inside the housing 101; when the sliding plate 501 is slid inward, the distance between the sliding plate 501 and the housing 101 increases, and the space between the sliding plate 501 and the housing 101 increases, resulting in a decrease in air pressure between the sliding plate 501 and the housing 101, and the external atmospheric pressure pushes the sealing plate 404 on the inside of the fixing plate I 402 to move inward and separate from the fixing plate I 402, thereby opening the air inlet 107 and drawing external gas into the housing 101, thereby achieving the effect of driving gas flow.
[0044] like Figure 1-7 As shown in 9-10, this example can achieve the effect of sliding skateboard 501.
[0045] Because a connecting rod 502 is fixedly connected to the inner side of the slide plate 501 in the motor, and a slide 503 is fixedly connected to the end of the connecting rod 502, and a cam 105 is fixedly connected to the upper part of the output shaft 104, the cam 105 is slidably connected inside the slide 503, and a sliding hole 206 is opened inside the cross plate 201, the connecting rod 502 slides in the sliding hole 206; when the output shaft 104 rotates, it drives the cam 105 to rotate, and then the cam 105 pushes and squeezes the slide 503 during the rotation process, thereby driving the slide 503 to move longitudinally back and forth, thereby driving the connecting rod 502 to move back and forth in the sliding hole 206, thereby driving the slide plate 501 to move, thereby achieving the effect of sliding the slide plate 501.
