[0002] A permanent magnet synchronous motor is a synchronous motor that uses permanent magnets to generate a magnetic field. The speed of its rotor is consistent with the current frequency of the stator winding. The permanent magnet synchronous motor is composed of components such as a stator, a rotor and an end cover. The stator is basically the same as an ordinary induction motor. It uses a laminated structure to reduce the iron loss during motor operation. The rotor can be made solid or laminated.

[0024] Specific examples are given below.

[0025] like Figures 1 to 3 As shown, an easy-to-open and close permanent magnet motor with a stable structure according to an embodiment of the present invention comprises a motor box 1, a back plate 2 and a front plate 3 are provided at both ends of the motor box 1, a first fixing block 4 is fixedly connected to the side walls of the back plate 2 and the front plate 3, and a plurality of first fixing blocks 4 are arranged in a circular array, a second fixing block 6 is fixedly connected to the side wall of the motor box 1, and a plurality of second fixing blocks 6 are arranged corresponding to the positions of the first fixing blocks 4, a fixing rod 5 is rotatably connected inside the first fixing block 4, and a nut is provided at the end of the fixing rod 5, a stator 8 and a rotor 10 are provided inside the motor box 1, a winding protrusion 9 is provided inside the stator 8, and a plurality of winding protrusions 9 are arranged corresponding to the size of the rotor 10, an output rod 11 is fixedly connected to the side wall of the rotor 10, and during work, the staff can wind coils on the plurality of winding protrusions 9 provided inside the stator 8, and can wind coils correspondingly on the side wall of the rotor 10, thereby realizing the motor box. 1 and the installation of the internal components of the motor box 1. After the coil is wound, the staff can align the front plate 3 with the end of the motor box 1 where the output rod 11 is located, and align the back plate 2 with the other end of the motor box 1. After alignment, the staff can rotate the fixing rods 5 at the ends of the multiple first fixing blocks 4, and place the fixing rods 5 away from the ends of the first fixing blocks 4 in the corresponding second fixing blocks 6. After installing the fixing rods 5 in the second fixing blocks 6, the staff can rotate the multiple nuts until the nuts are tightened. After the nuts are tightened, the connection between the motor box 1, the back plate 2, and the front plate 3 is completed. This step achieves the effect of convenient opening and closing by setting the first fixing block 4, the fixing rod 5, and the second fixing block 6 for the installation of the open and close permanent magnet motor, which is beneficial to solving the problem of screw aging in traditional screw connection. The structure that is easy to open and close provides convenience for maintenance personnel, which is beneficial to shorten the maintenance time and improve the maintenance efficiency.

[0026] like Figure 3 and Figure 4As shown, a fixed disk 13 is provided at the end of the stator 8, and a fixed protrusion 14 is fixedly connected to the side wall of the fixed disk 13. A plurality of fixed protrusions 14 are arranged in a circular array, and screws are arranged between the fixed protrusion 14 and the fixed disk 13. A limit strip 15 is fixedly connected to the side wall of the fixed disk 13, and a plurality of limit strips 15 are arranged corresponding to the position of the winding protrusion 9. A plurality of limit strips 15 are fixedly connected to the ends away from the fixed disk 13 with a support ring 16. During work, the staff can install the internal stabilizing structure composed of the fixed disk 13, the limit strip 15, and the support ring 16 between the winding protrusion 9 and the rotor 10 by screws. During the process, since a plurality of limit strips 15 correspond to the winding protrusions The position of block 9 is set, and the fixing disk 13, the limiting strip 15 and the supporting ring 16 are fixed inside the stator 8 by screws between the fixing protrusion 14 and the stator 8. During the rotation of the rotor 10, the multiple limiting strips 15 can prevent the winding protrusion 9 from contacting the rotor 10 by themselves, thereby preventing the coils on the side walls of the two from contacting each other. This step is beneficial to avoid the rotor 10 from contacting the winding protrusion 9 during rotation and avoiding the coils on the side walls of the two from contacting each other by setting multiple limiting strips 15 to fill the gap between the winding protrusion 9 and the rotor 10, thereby reducing safety hazards, improving the stability and anti-interference ability of the permanent magnet motor, and reducing noise.

[0027] like Figure 1 As shown, a sleeve groove is provided on the side wall of the front plate 3, and a fixing ring 17 is provided on the side wall of the sleeve groove. A screw is provided between the mounting groove and the fixing ring 17, and a plurality of screws are arranged in a circumferential array. A lubricating sleeve 18 is fixedly connected to the side wall of the fixing ring 17, and the lubricating sleeve 18 is set corresponding to the size of the sleeve groove. When working, whenever the permanent magnet motor starts to operate, the output rod 11 fixedly connected to the side wall of the rotor 10 will rotate synchronously with the rotor 10. During the rotation of the output rod 11, the lubricating sleeve 18 arranged inside the front plate 3 can be replaced by itself. The front plate 3 is replaced to contact the output rod 11, so as to play its role in reducing the friction coefficient. The staff can regularly remove multiple screws, remove the fixing ring 17 and the lubricating sleeve 18 from the sleeve groove, and then replace and maintain the fixing ring 17 and the lubricating sleeve 18. This step reduces the friction coefficient between components by setting the fixing ring 17 and the lubricating sleeve 18, thereby reducing the friction between components and delaying the wear process between components, which is beneficial to prolonging the service life of the permanent magnet motor, improving the working stability of the motor, reducing noise, and reducing maintenance requirements.

[0028] like Figure 2 and Figure 3As shown, a docking groove is provided at the end of the motor box 1, and a docking block 19 is fixedly connected to the side wall of the front plate 3, and the docking block 19 is set corresponding to the size of the docking groove. During work, whenever the staff installs the front plate 3 on the end of the motor box 1, the docking block 19 fixedly connected to the side wall of the motor box 1 will enter the docking groove corresponding to the end of the motor box 1. In daily work, the docking block 19 can increase the connection strength between the motor box 1 and the front plate 3 by reducing the contact area between the front plate 3 and the motor box 1. This step seals the connection between the motor box 1 and the front plate 3 by setting the docking block 19 and the docking groove, thereby improving the structural stability and anti-interference ability of the permanent magnet motor, which is beneficial to prolonging the service life of the permanent magnet motor.

[0029] like Figure 3 As shown, a sealing ring 12 is provided at the end of the motor box 1, and the sealing ring 12 is set to the size of the docking block 19. During operation, whenever the staff installs the front plate 3 on the end of the motor box 1, the sealing ring 12 located between the docking block 19 and the motor box 1 will be squeezed and deformed by the two. This step improves the sealing performance of the permanent magnet motor by setting the sealing ring 12 to fill the gap between the docking block 19 and the motor box 1, which is beneficial to prevent water from invading the interior of the motor, reducing safety hazards, and improving the stability and reliability of the permanent magnet motor.

[0030] like Figure 3 As shown, a bearing platform 7 is fixedly connected to the side wall of the second fixed block 6, and the bearing platform 7 corresponds to the size setting of the fixed rod 5. The bearing platform 7 is made of rubber material. During operation, when the staff tightens the nut at the end of the fixed rod 5 to the end of the second fixed block 6, the bearing platform 7 squeezed by the nut can be deformed by its own rubber material. Whenever the nut is loose, the bearing platform 7 made of rubber material can rebound to a certain extent, thereby preventing the nut and the second fixed block 6 from losing stress between each other. This step is achieved by setting the bearing platform 7 and using rubber material to maintain the stress stability of the fixed rod 5, which is conducive to solving the problem of immediate disintegration of the component when the nut is loose, thereby improving the structural stability of the permanent magnet motor, and is conducive to extending the service life and maintenance cycle.

[0031] like Figure 4 As shown, the fixed disk 13, the limiting strip 15 and the supporting ring 16 are made of plastic material. When working, the fixed disk 13, the limiting strip 15 and the supporting ring 16 made of plastic material can give play to their advantages of insulation, low density and strong plasticity. This step improves the stability of the permanent magnet motor, increases structural fault tolerance and reduces the overall quality of the motor by using rubber material for the fixed disk 13, the limiting strip 15 and the supporting ring 16.

[0032] During operation, the staff can wind coils on the multiple winding protrusions 9 opened inside the stator 8, and can wind coils correspondingly on the side walls of the rotor 10, so as to realize the installation of the motor box 1 and the internal components of the motor box 1. After the coils are wound, the staff can align the front plate 3 with the end of the motor box 1 where the output rod 11 is located, and align the back plate 2 with the other end of the motor box 1. After alignment, the staff can rotate the fixing rods 5 at the ends of the multiple first fixing blocks 4, and place the ends of the fixing rods 5 away from the first fixing blocks 4 in the corresponding second fixing blocks 6. After installing the fixing rods 5 in the second fixing blocks 6, the staff can rotate the multiple nuts until the nuts are tightened. After the nuts are tightened, After completing the connection between the motor box 1, the back plate 2, and the front plate 3, the staff can install the internal stabilization structure composed of the fixed disk 13, the limit strip 15, and the support ring 16 between the winding protrusion 9 and the rotor 10 through screws. During the process, since the multiple limit strips 15 are arranged corresponding to the positions of the winding protrusion 9, and the fixed disk 13, the limit strip 15 and the support ring 16 are fixed to the inside of the stator 8 through the screws between the fixed protrusion 14 and the stator 8, during the rotation of the rotor 10, the multiple limit strips 15 can prevent the winding protrusion 9 from contacting the rotor 10 by themselves, thereby preventing the coils on the side walls of the two from contacting. Whenever the permanent magnet motor starts to operate, the output rod fixed to the side wall of the rotor 10 11 will rotate synchronously with the rotor 10. During the rotation of the output rod 11, the lubricating sleeve 18 arranged inside the front plate 3 can contact the output rod 11 by replacing the front plate 3, thereby playing the role of reducing the friction coefficient. Among them, the staff can regularly remove multiple screws, remove the fixing ring 17 and the lubricating sleeve 18 from the sleeve groove, and then replace and maintain the fixing ring 17 and the lubricating sleeve 18. Whenever the staff installs the front plate 3 at the end of the motor box 1, the docking block 19 fixed on the side wall of the motor box 1 will enter the docking groove corresponding to the end of the motor box 1. In daily work, the docking block 19 can reduce the contact between the front plate 3 and the motor box 1. The area is placed to increase the connection strength between the motor box 1 and the front plate 3. Whenever the staff installs the front plate 3 on the end of the motor box 1, the sealing ring 12 between the docking block 19 and the motor box 1 will be squeezed by the two and deformed. When the staff tightens the nut at the end of the fixing rod 5 to the end of the second fixing block 6, the bearing platform 7 squeezed by the nut can be deformed by its own rubber material. Whenever the nut is loose, the bearing platform 7 made of rubber material can rebound to a certain extent, thereby preventing the nut and the second fixing block 6 from losing stress between each other. The fixing plate 13, the limit strip 15 and the support ring 16 made of plastic material can give full play to their advantages of insulation, low density and strong plasticity.
