DETAILED DESCRIPTION

[0023] In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model is further illustrated below in conjunction with the drawings and examples.It needs to be explained that the embodiment of the application and the features in the embodiment can be combined mutually without conflict.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as shown in the attached document Figure 1 - Figure 5 As shown, it includes a housing 1, an output stabilization mechanism 4, and a temperature detection mechanism 6. The output stabilization mechanism 4 includes a collar 401 and a permanent magnet 405. The permanent magnet 405 and the collar 401 are internally slidably connected. The collar 401 and the permanent magnet 405 are used to stabilize the motor magnetic field, which can reduce fluctuations during motor operation and improve the stability of motor output.

[0026] The temperature detection mechanism 6 includes a heat-conducting block 603 and a metal tube 602. The heat-conducting block 603 and the metal tube 602 are used to transfer heat from the motor. The heat inside the motor is judged based on the thermal expansion and contraction of the metal tube 602, and the motor is cooled down in time.

[0027] The overall effect of Embodiment 1 is as follows: by using the attraction between the permanent magnet 405 and the outer surface of the outer shell 1, the magnetic field inside the motor can be controlled. The rotation of the rotating rod 2 can be used to observe whether the motor fluctuates during operation. By adjusting multiple permanent magnets 405, the stability of the motor output can be improved. At the same time, the heat-conducting block 603 can be used to transfer heat from the surface of the outer shell 1. By observing the effect of thermal expansion on the metal tube 602, the heat inside the motor can be judged, which facilitates timely heat dissipation of the motor.

[0028] Example 2, as Figure 2 - Figure 3 As shown, the output stabilizing mechanism 4 also includes a storage block 402, which is evenly distributed on the outer surface of the collar 401. A push plate 403 is fitted inside the storage block 402. A connecting plate 404 is fixedly connected to the side surface of the push plate 403, and the connecting plate 404 is fixedly connected to the permanent magnet 405. An opening and closing mechanism 5 is provided on the inner wall of the collar 401. The opening and closing mechanism 5 includes a spring 502, which is fixedly connected to the inner wall of the collar 401. A rubber seat 501 is fixedly connected to the end of the spring 502 away from the collar 401, and the rubber seat 501 corresponds to the permanent magnet 405.

[0029] The effect achieved by the whole embodiment 2 is that when the motor is in use, the push plate 403 is pushed to the surface of the sleeve ring 401 by the connection of the push plate 403 and the connecting plate 404, so that the push plate 403 can push the permanent magnet 405 to move by the connecting plate 404, and the permanent magnet 405 can extend from the inside of the sleeve ring 401. Through the extension of the permanent magnet 405, it can be attached to the surface of the rubber seat 501. When the push plate 403 is continuously pushed, the permanent magnet 405 can extrude and expand the rubber seat 501. The elasticity of the spring 502 can change the direction of the rubber seat 501, so that the rubber seat 501 can open and extend the permanent magnet 405 from the inside of the sleeve ring 401 to the surface of the shell 1. Because the width of the connecting plate 404 is smaller than that of the permanent magnet 405, when the connecting plate 404 is attached to the surface of the rubber seat 501, the expanding diameter of the rubber seat 501 can be changed, so that the rubber seat 501 can clamp the connecting plate 404. According to the attraction between the permanent magnet 405 and the motor, the magnetic field strength of the motor can be enhanced, thereby improving the torque and efficiency of the motor, reducing the fluctuation of the motor during operation, and improving the stability of the motor output.

[0030] Embodiment 3, as Figure 4 Figure 5 The outer surface of the shell 1 is provided with a mounting mechanism 3, and the mounting mechanism 3 comprises a mounting ring 301.

The temperature detection mechanism 6 further comprises a copper block 601. One side surface of the copper block 601 penetrates the inside of the mounting ring 301 and is fixedly connected with the heat-conducting block 603. The other side surface of the copper block 601 is fixedly connected with the metal pipe 602.

[0031] The effect achieved by the whole embodiment 3 is that the mounting ring 301 is sleeved on the surface of the motor shell 1, so that the heat-conducting block 603 can be attached to the surface of the shell 1. The heat-conducting block 603 can conduct the heat transferred on the surface of the shell 1 in the motor, so that the heat-conducting block 603 can conduct the heat to the copper block 601 and the metal pipe 602. Because the molecular motion of the metal pipe 602 changes with temperature, when the temperature rises, the molecular motion intensifies, causing the metal sheet to expand in volume. When the temperature decreases, the molecular motion slows down and the volume shrinks. Because the surface of the observation rack 302 is provided with a circular hole, and the diameter of the circular hole is greater than that of the metal pipe 602, the change of the spacing between the metal pipe 602 and the circular hole can be used to judge the heat in the motor, so that the motor can be cooled in time, and the service life of the motor is improved.

[0033] The effect achieved by the whole embodiment 4 is that the outer surface of the enameled wire winding 8 is sleeved with a hollow cup stator, the stator of the hollow cup motor is composed of permanent magnets, forming a closed magnetic path, the hollow cup rotor 10 is a hollow cup structure without iron core, and is only composed of the enameled wire winding 8, when the current passes through the winding, the charged conductor is subjected to the Lorentz force in the stator magnetic field, and a pair of torques are generated in the upper and lower windings due to the opposite directions of the current, driving the rotating rod 2 to rotate.

[0034] The working principle of the whole device is that by connecting the push plate 403 and the connecting plate 404, the push plate 403 can be pushed to the surface of the sleeve ring 401, so that the push plate 403 can push the permanent magnet 405 to move by the connecting plate 404, and the permanent magnet 405 can extend from the inside of the sleeve ring 401, so that it can be attached to the surface of the rubber seat 501, when the push plate 403 is continuously pushed, the permanent magnet 405 can extrude and expand the rubber seat 501, and the elasticity of the spring 502 can change the direction of the rubber seat 501, so that the rubber seat 501 can open and extend the permanent magnet 405 from the inside of the sleeve ring 401 to the surface of the shell 1, and because the width of the connecting plate 404 is less than that of the permanent magnet 405, when the connecting plate 404 is attached to the surface of the rubber seat 501, the expansion diameter of the rubber seat 501 can be changed, so that the rubber seat 501 can clamp the connecting plate 404, and according to the attraction between the permanent magnet 405 and the motor, the magnetic field strength of the motor can be enhanced;

[0035] The stator of the hollow cup motor is composed of permanent magnets, forming a closed magnetic circuit, the hollow cup rotor 10 is a hollow cup structure without iron core, only composed of a winding 8 of enameled wire, when current passes through the winding, the charged conductor is subjected to Lorentz force in the magnetic field of the stator, the upper and lower windings generate a pair of torques due to opposite current directions, driving the rotating rod 2 to rotate, the heat transferred on the surface of the shell 1 in the motor can be conducted by using the heat conducting block 603, so that the heat conducting block 603 can conduct heat to the copper block 601 and the metal pipe 602, since the molecular movement of the material of the metal pipe 602 changes with temperature, when the temperature rises, the molecular movement intensifies, resulting in the volume expansion of the metal sheet, when the temperature decreases, the molecular movement slows down and the volume shrinks, since the surface of the observation frame 302 is provided with a circular hole, and the diameter of the circular hole is greater than that of the metal pipe 602, the heat in the motor is judged according to the change of the spacing between the metal pipe 602 and the circular hole.
