Description

Technical Field

[0001] The present invention relates to the field of motor assembly, and particularly to a modular and quickly assembled permanent magnet synchronous servo motor structure. Background Art

[0002] A permanent magnet synchronous servo motor is an efficient and high-precision motor, which is widely used in the fields of industrial automation and robotics. It uses permanent magnets to generate a stable magnetic field and combines synchronous control technology to achieve precise position, speed, and torque control. This motor has the advantages of fast response, low noise, and high reliability, and is suitable for occasions that require high dynamic performance and precise control. Due to its excellent performance, the permanent magnet synchronous servo motor has been widely used in equipment such as CNC machine tools, 3D printers, and automated production lines.

[0003] Currently, the existing outer shells of permanent magnet synchronous servo motors are usually of an integrated structure and can only be used in conventional environments. When a permanent magnet synchronous servo motor is applied in some specific environments, such as specific environments with requirements for temperature and corrosion resistance, the conventional outer shell cannot meet the usage requirements of the specific environment. Due to the integrated design of the conventional outer shell, it cannot be replaced, and users need to purchase specific permanent magnet synchronous servo motors for applications in specific environments, which increases the cost and management difficulty.

[0004] Therefore, a modular and quickly assembled permanent magnet synchronous servo motor structure is proposed to solve the problem that the conventional outer shell cannot be applied to specific environments. Summary of the Invention The purpose of the present invention is to provide a modular and quickly assembled permanent magnet synchronous servo motor structure to solve the problem that the conventional outer shell cannot be applied to specific environments.

[0005] To achieve this purpose, the present invention adopts the following technical solutions: A modular and quickly assembled permanent magnet synchronous servo motor structure includes an end cap group and a housing that are inserted into each other to form a z-axis direction limit. On one side of the end cap group close to the housing, there are blocks inclined in the z-axis direction. Corresponding to the blocks, grooves are provided at the positions near the ends on the outer side of the housing. The blocks are snapped into the grooves to form a y-axis direction limit; a limiting unit is provided on the housing. The limiting unit includes a positioning sleeve and a rotating rod. The positioning sleeve is threadedly connected to the rotating rod. By rotating the rotating rod, the positioning sleeve can move along the y-axis direction towards the block and be inserted into the block to form an x-axis direction limit; the block is snapped into the groove and inserted into the positioning sleeve, so that the end cap group and the housing form three-direction limits in the x-axis, y-axis, and z-axis directions.

[0006] Preferably, a limiting block is fixed on the inner wall of the groove near the positioning sleeve. A limiting groove is formed in the clamping block corresponding to the limiting block. The limiting block is slidably connected to the limiting groove, and the connection between the limiting block and the limiting groove restricts the clamping block in the y-axis direction.

[0007] Preferably, a receiving groove communicating with the groove is formed in the side surface of the housing along the y-axis direction. The positioning sleeve and the rotating rod are both arranged in the receiving groove along the y-axis direction. A support plate is fixed in the receiving groove. The positioning sleeve penetrates through the support plate and is slidably connected in the support plate. A movable member is arranged in the receiving groove along the y-axis direction. A spiral chute is formed on the outer side of the rotating rod. The movable member is slidably connected in the chute, and the rotation of the rotating rod is caused after the movement of the movable member. A positioning hole is formed in the clamping block along the y-axis direction. When the clamping block is located in the receiving groove, the positioning sleeve moves along the y-axis direction and is inserted into the clamping block through the positioning hole, restricting the clamping block in the x-axis direction.

[0008] Preferably, the end cover group includes a first end cover and a second end cover. The first end cover and the second end cover respectively abut against both ends of the housing. The number of clamping blocks is eight, and they are equally spaced in groups of four and respectively arranged on the sides of the first end cover and the second end cover close to the housing. The four clamping blocks in each group are distributed in a rectangular shape.

[0009] Preferably, two grooves on the same y-axis line are communicated with the corresponding receiving grooves. The number of positioning sleeves in one of the receiving grooves is two. External threads are symmetrically arranged at the part of the outer side of the rotating rod close to its end. Thread grooves are formed in the inner wall of the positioning sleeve corresponding to the external threads. The external threads are threadedly connected to the thread grooves.

[0010] Preferably, the movable member includes a movable plate and a movable rod. The cross-sectional shape of the movable plate is in the shape of a Chinese character 'hui'. A moving groove is formed on the outer circumference of the housing corresponding to the movable plate, and the moving groove is vertically communicated with the receiving groove. The movable plate moves along the y-axis direction in the chute. The number of movable rods is equal to the number of chutes. The movable rods are all arranged on the inner side of the movable plate. One end of the movable rod far away from the movable plate penetrates and extends into the chute, and the movable rod is slidably connected to the chute. After the movement of the movable plate, the rotating rod is rotated through the movable rod.

[0011] Preferably, a baffle capable of moving along the y-axis direction is sleeved on the housing corresponding to the moving groove. The cross-sectional shape of the baffle is in the shape of a Chinese character 'hui'. The width of the baffle is greater than the width of the inner cavity of the moving groove, and the baffle and the moving groove are on the same x-axis line. The baffle is connected to the housing through an elastic unit. The baffle is used to reset the baffle after movement. When the elastic unit is in the normal state, the baffle overlaps with the moving groove; when the elastic unit is in the contracted state, the baffle is misaligned with the moving groove.

[0012] Preferably, an installation groove is formed in the housing corresponding to the baffle along the y-axis direction. The elastic unit includes a spring and a slider. The slider is slidably connected in the installation groove, and the spring is fixed between the installation groove and the slider. The slider is fixed to the inner side of the baffle.

[0013] Preferably, abutting portions are formed on one side of the first end cap and the second end cap close to the housing. The abutting portions are inserted into the housing. An inner sleeve located inside the housing is abutted between the two abutting portions. The abutting portions are used for positioning the inner sleeve. The inner sleeve is detachably arranged inside the housing.

[0014] Preferably, a limiting groove is formed in the inner sleeve along the y-axis direction. A limiting portion corresponding to the limiting groove is formed on the inner wall of the housing. The limiting portion is slidably connected with the limiting groove and limits the rotation of the inner sleeve inside the housing. The inner sleeve includes a first sleeve and a second sleeve. The limiting groove is formed in the first sleeve. The cross-sections of the first sleeve and the second sleeve are both arc-shaped.

A connecting portion is formed at the portion of the first sleeve corresponding to the first abutting area, and a connecting groove is formed at the portion of the second sleeve corresponding to the second abutting area. The connecting portion is inserted into the connecting groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. For the modular and quickly assembled permanent magnet synchronous servo motor structure of the present invention, by setting the outer shell module, it is convenient to replace different end cap groups and the housing, so that the motor can adapt to a specific environment, improving the flexibility of the motor, meeting specific application requirements, reducing the replacement cost of users. At the same time, through the connection of the positioning sleeve, the clamping block and the groove, the assembly steps of the end cap group and the housing are simplified, and the quick assembly of the outer shell can be realized, improving the installation efficiency. And by restricting the connection between the end cap group and the housing from multiple angles, the stability and reliability of the assembled motor are also improved, reducing the possibility of faults.

[0016] 2. For the modular and quickly assembled permanent magnet synchronous servo motor structure of the present invention, the moving rods can make multiple rotating rods rotate, so as to realize the synchronous movement of multiple positioning sleeves, so as to quickly lock the first end cap and the second end cap. By the above synchronous assembly method, the assembly steps are further simplified, reducing the labor cost and time consumption.

[0017] 3. For the modular and quickly assembled permanent magnet synchronous servo motor structure of the present invention, through the cooperation of the baffle, the elastic unit and the sliding groove, the moving plate can be shielded to avoid the influence of the moving plate caused by external contact or misoperation, ensuring the precise docking of the positioning sleeve.

[0018] 4. The modular and quickly assembled permanent magnet synchronous servo motor structure of the present invention enables the replacement of the internal structure of the motor to be more convenient by detachably arranging the inner sleeve, avoiding reinstalling the internal components every time the housing is replaced, saving time and labor costs. At the same time, the cooperation between the limiting groove and the limiting block also ensures the stability of the inner sleeve in the housing, preventing unnecessary rotation of the installed components and ensuring the stability of the motor components during operation. In addition, the modular design of the stator and rotor allows for quick replacement according to different application scenarios, and users do not need to purchase multiple motors, thus effectively reducing costs and improving economy.

Detailed implementation manners

[0023] To make the invention objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present at the same time.

[0025] Embodiment 1: Please refer to Figures 1 - 11, a modular and quickly assembled permanent magnet synchronous servo motor structure in this embodiment includes an end cap group 2 and a housing 1 that are inserted into each other to form a z-axis direction limit. On one side of the end cap group 2 close to the housing 1, there are clamping blocks 21 that are inclined in the z-axis direction. Corresponding to the clamping blocks 21, grooves 11 are provided at the position near the end of the outer side of the housing 1. The clamping blocks 21 are clamped in the grooves 11 to form a y-axis direction limit; a limiting unit 12 is provided on the housing 1. The limiting unit 12 includes a positioning sleeve 121 and a rotating rod 122. The positioning sleeve 121 is threadedly connected to the rotating rod 122. Rotating the rotating rod 122 can make the positioning sleeve 121 move along the y-axis direction towards the clamping block 21 and be inserted into the clamping block 21 to form an x-axis direction limit; the clamping blocks 21 are clamped with the grooves 11 and are inserted into the positioning sleeve 121, so that the end cap group 2 and the housing 1 form three-direction limits in the x-axis, y-axis, and z-axis directions.

[0026] It should be noted that the outer shell includes the end cap group 2 and the housing 1; when the motor needs to be applied in a specific environment, the housing 1 can be replaced. Replace the conventional housing 1 with a specific housing 1, so that the motor can be used in a specific environment. By modularly setting the motor housing 1, the replacement of the housing 1 is realized. Compared with the traditional integrated structure motor housing 1, the adaptability of the motor is improved and the cost of the user is reduced.

[0027] During application, when the housing 1 needs to be replaced, first separate the housing 1 from the internal structure of the motor, and then assemble the internal structure of the motor with the specific housing 1. During assembly, first reinstall the internal structure of the motor, and then connect the end cap group 2 and the housing 1. When connecting the end cap group 2 and the housing 1, make the clamping blocks 21 correspond to the grooves 11, and insert the end cap group 2 and the housing 1. After the insertion is completed, rotate the end cap group 2 to make the clamping blocks 21 clamped with the grooves 11. At this time, the clamping blocks 21 correspond to the positioning sleeve 121. Subsequently, rotate the rotating rod 122 to make the positioning sleeve 121 move towards the clamping block 21. After the positioning sleeve 121 is inserted into the clamping block 21, three-direction limits of the x-axis, y-axis, and z-axis of the clamping block 21 can be formed, thus completing the connection between the end cap group 2 and the housing 1; by replacing the housing 1 in the above manner, the motor can be applied to a specific environment. At the same time, the above method also simplifies the assembly steps of the housing 1 and the end cap group 2. Just rotating the rotating rod 122 can realize the assembly of the housing 1 and the end cap, effectively improving the installation efficiency.

[0028] It can be understood that the disassembly process of the housing 1 and the end cap group 2 can be obtained through the composition process. Those skilled in the art know that the sealing performance of the connection between the housing 1 and the end cap is well known to those skilled in the art, and this embodiment will not be described again.

[0029] Further, please refer to Figure 3, a limiting block 111 is fixed on the inner wall of the groove 11 near the positioning sleeve 121. A limiting groove 212 is provided on the clamping block 21 corresponding to the limiting block 111. The limiting block 111 is slidably connected to the limiting groove 212, and the connection between the limiting block 111 and the limiting groove 212 forms a limit in the y-axis direction for the clamping block 21.

[0030] It should be noted that after the end cover group 2 is inserted into the housing 1, a limit in the z-axis direction is formed between the end cover and the housing 1. By rotating the end cover group 2 to rotate the clamping block 21 and making the limiting block 111 connected to the limiting groove 212, a limit in the y-axis direction can be formed between the end cover group 2 and the housing 1, thus forming a preliminary connection between the end cover group 2 and the housing 1, which is convenient for the subsequent insertion of the positioning sleeve 121 and the clamping block 21. Through the preliminary connection between the end cover group 2 and the housing 1, the positioning effect of the end cover group 2 when connected to the housing 1 is improved.

[0031] In addition, by arranging the limiting block 111 in the groove 11, the internal space of the groove 11 is effectively utilized, making the structure more compact, enabling the clamping block 21 to be smoothly clamped during the assembly process of the end cover group 2 and the housing 1, and completing the preliminary connection between the end cover group 2 and the housing 1, simplifying the assembly steps and improving the assembly efficiency. At the same time, the limiting block 111 can also effectively disperse the stress applied on the clamping block 21, thereby reducing the phenomenon of stress concentration and improving the service life.

[0032] Further, please refer to Figures 1 - 4 , a receiving groove 13 communicating with the groove 11 is provided on the side surface of the housing 1 along the y-axis direction. The positioning sleeve 121 and the rotating rod 122 are both arranged in the receiving groove 13 along the y-axis direction. A support plate 131 is fixed in the receiving groove 13. The positioning sleeve 121 penetrates through the support plate 131 and is slidably connected within the support plate 131. A movable member 14 is arranged in the receiving groove 13 along the y-axis direction. A spiral chute 123 is provided on the outer side of the rotating rod 122. The movable member 14 is slidably connected in the chute 123, and the rotation of the rotating rod 122 is caused after the movement of the movable member 14; A positioning hole 211 is provided in the clamping block 21 along the y-axis direction. When the clamping block 21 is located in the receiving groove 13, the positioning sleeve 121 moves along the y-axis direction and is inserted into the clamping block 21 through the positioning hole 211, forming a limit in the x-axis direction for the clamping block 21.

[0033] During application, when the clamping block 21 corresponds to the positioning sleeve 121 and the positioning hole 211 is aligned with the positioning sleeve 121, the moving part 14 can move along the y-axis direction in the accommodation groove 13. When the moving part 14 moves, it will slide in the spiral chute 123. After the moving part 14 moves, the rotating rod 122 will rotate through the chute 123. As the rotating rod 122 rotates, the positioning sleeve 121 threadedly connected to the rotating rod 122 will move towards the positioning hole 211 until it is inserted into the positioning hole 211. When the positioning sleeve 121 is connected to the positioning hole 211, through their cooperation, the clamping block 21 can be restricted in the x-axis direction.

[0034] It should be noted that through the connection between the limiting block 111 and the limiting groove 212, the clamping block 21 is restricted in the z-axis and y-axis directions. Coupled with the connection between the positioning sleeve 121 and the positioning hole 211, the clamping block 21 is restricted in the x-axis direction, which can improve the stability of the end cover group 2 when connected to the housing 1, thereby ensuring the stability of the motor after the modular housing 1 is replaced.

[0035] It also should be noted that when the rotating rod 122 moves the positioning sleeve 121 through the cooperation of the external thread 124 and the thread groove 125, the support plate 131 penetrated by the positioning sleeve 121 can support and limit the positioning sleeve 121. Since the cross-sectional shape of the positioning sleeve 121 is square, the perforation corresponding to the positioning sleeve 121 on the support plate 131 is also square, and the two can form a limit to the positioning sleeve 121 in cooperation.

[0036] In addition, by moving the moving part 14 to rotate the rotating rod 122 and then moving the positioning sleeve 121 to be inserted into the clamping block 21, the connection between the end cover group 2 and the housing 1 can be made more stable, so as to avoid the connection between the end cover group 2 and the housing 1 being impacted and the connection between the positioning sleeve 121 and the clamping block 21 failing. Moreover, the moving part 14 makes the positioning sleeve 121 inserted into the clamping block 21 through the rotating rod 122, and under the action of the spiral chute 123, multi-stage locking is realized, further improving the stability.

[0037] Embodiment 2: The basic content is the same as that of Embodiment 1, the difference is: Please refer to Figures 1 - 9 , in this embodiment, the end cover group 2 includes a first end cover 22 and a second end cover 23. The first end cover 22 and the second end cover 23 respectively abut against both ends of the housing 1. The number of clamping blocks 21 is eight, and they are equally spaced in groups of four and are respectively arranged on the sides of the first end cover 22 and the second end cover 23 close to the housing 1. The four clamping blocks 21 in each group are arranged in a rectangular distribution.

[0038] It should be noted that by further refining the end - cover group 2 into a modular form, more choices can be provided for the motor housing 1 when applied in a specific environment. For example, the first end - cover 22 corresponds to the output shaft of the motor. By using a specific first end - cover 22, the usage requirements of the motor output shaft in a specific environment can be met, so as to improve the usage effect and service life of the motor. By further modularizing the first end - cover 22 and the second end - cover 23, not only can the usage requirements of the motor in a specific environment be further met, but also the material and processing - technology requirements for both in a specific environment can be satisfied, realizing cost optimization.

[0039] In addition, both the first end - cover 22 and the second end - cover 23 are connected to the housing 1 through the cooperation of four groups of blocks 21 and grooves 11, which can effectively improve the stability of the connection between the first end - cover 22, the second end - cover 23 and the housing 1, effectively disperse the pressure applied at the connection points, reduce local stress concentration, and extend the service life of each component.

[0040] Furthermore, please refer to Figure 5 , two grooves 11 on the same y - axis line are connected to the corresponding receiving grooves 13. The number of positioning sleeves 121 in one of the receiving grooves 13 is two. External threads 124 are symmetrically arranged at the outer side of the rotating rod 122 near its end. Thread grooves 125 are provided on the inner wall of the positioning sleeve 121 corresponding to the external threads 124, and the external threads 124 are in threaded connection with the thread grooves 125.

[0041] It should be noted that after the rotating rod 122 rotates, through the cooperation of two symmetrically arranged external threads 124 and the corresponding thread grooves 125, the two positioning sleeves 121 can move away from or towards each other. When the two positioning sleeves 121 move away from each other, the positioning sleeves 121 can be connected to the positioning holes 211 to form a clamping connection to the blocks 21.

[0042] It can be known that by driving two positioning sleeves 121 to move and be clamped with the corresponding two blocks 21 through a rotating rotating rod 122, the positioning and limiting of the first end - cover 22 and the second end - cover 23 can be synchronized, thereby improving the working efficiency of the connection between the first end - cover 22, the second end - cover 23 and the housing 1 and realizing quick installation.

[0043] Even further, please refer to Figures 6 - 7, the moving member 14 includes a moving plate 141 and moving rods 142. The cross-sectional shape of the moving plate 141 is a double-square shape. A moving groove 15 is provided on the outer periphery of the housing 1 corresponding to the moving plate 141, and the moving groove 15 is vertically communicated with the accommodating groove 13. The moving plate 141 moves along the y-axis direction in the sliding groove 123. The number of the moving rods 142 is equal to that of the sliding grooves 123. The moving rods 142 are all arranged inside the moving plate 141. One end of the moving rod 142 away from the moving plate 141 penetrates and extends into the sliding groove 123, and the moving rod 142 is slidably connected with the sliding groove 123. After the moving plate 141 moves, the rotating rod 122 is rotated by the moving rod 142.

[0044] It should be noted that by moving the moving plate 141 in the moving groove 15, the four moving rods 142 can be driven to move. After the four moving rods 142 move, the four rotating rods 122 can be rotated in cooperation with the corresponding sliding grooves 123. As the four rotating rods 122 rotate, the positioning sleeves 121 corresponding to each rotating rod 122 can complete the clamping with the corresponding clamping blocks 21. Through the above method and the cooperation of each structure, the connection between the positioning sleeves 121 of the corresponding first end cover 22 and the second end cover 23 and the corresponding clamping blocks 21 can be realized by moving the moving plate 141, so as to realize the connection between the first end cover 22, the second end cover 23 and the housing 1, and further improve the efficiency during connection. There is no need to rotate each rotating rod 122 separately. By simply moving the moving plate 141, multiple rotating rods 122 can be driven to rotate, realizing multi-point linkage and further improving the assembly speed.

[0045] It can be known that the two positioning sleeves 121 located on the same y-axis are respectively supported by the corresponding support plates 131. Therefore, when the corresponding rotating rods 122 are arranged in these two positioning sleeves 121, the rotating rods 122 do not require additional support. Therefore, when the moving plate 141 drives the moving rods 142 to move in the spiral sliding grooves 123, the rotating rods 122 can be rotated, so as to realize the rotation of the corresponding two positioning sleeves 121.

[0046] It can be understood that when the moving plate 141 rotates the rotating rod 122 through the moving rod 142, the sliding grooves 123 corresponding to the moving rod 142 on each rotating rod 122 have the same spiral direction.

[0047] In addition, structures such as the moving plate 141, the moving rods 142, the rotating rods 122 and the positioning sleeves 121 are all arranged in the groove structures such as the accommodating groove 13 and the moving groove 15 on the housing 1, realizing the integration of the structure, making the structure more compact, without occupying the space on the surface of the housing 1, so that the influence on the motor during installation through the housing 1 is smaller.

[0048] Further, please refer to Figures 8 - 9, a baffle plate 16 that can move along the y-axis direction is sleeved on the housing 1 corresponding to the moving groove 15. The cross-sectional shape of the baffle plate 16 is a double-square shape. The width of the baffle plate 16 is greater than the width of the inner cavity of the moving groove 15, and the baffle plate 16 and the moving groove 15 are located on the same x-axis. The baffle plate 16 is connected to the housing 1 through an elastic unit 17. The baffle plate 16 is used to reset the moved baffle plate 16. When the elastic unit 17 is in a normal state, the baffle plate 16 overlaps with the moving groove 15; when the elastic unit 17 is in a contracted state, the baffle plate 16 is misaligned with the moving groove 15.

[0049] It should be noted that since the moving groove 15 is open, after the rotating rod 122 is rotated by the moving plate 141, the open moving groove 15 cannot protect the moved moving plate 141, and there may be misoperations on the moving plate 141 due to external factors. Therefore, by providing a baffle plate 16 on the housing 1 corresponding to the moving groove 15 to block the moving groove 15, the situation of misoperations on the moving plate 141 caused by external factors can be avoided.

[0050] Specifically, an installation groove 18 is opened on the housing 1 corresponding to the baffle plate 16 along the y-axis direction. The elastic unit 17 includes a spring 171 and a slider 172. The slider 172 is slidably connected in the installation groove 18, and the spring 171 is fixed between the installation groove 18 and the slider 172. The slider 172 is fixed to the inner side of the baffle plate 16.

[0051] During application, when the moving plate 141 needs to be moved, the baffle plate 16 needs to be moved first to release the blockage of the moving groove 15 by the baffle plate 16. By pushing the moving plate 141, the moving plate 141 can be moved toward the installation groove 18 direction, which can release the blockage of the moving groove 15 by the baffle plate 16. At this time, the moving plate 141 can be moved. When the moving plate 141 is pushed to move, the moving plate 141 will also cause the slider 172 to move in the installation groove 18, and the slider 172 will also squeeze the spring 171 in the installation groove 18, making the spring 171 in a contracted state. After the corresponding operation of the moving plate 141 is completed, the baffle plate 16 is released, and the spring 171 rebounds and resets. With its elastic force and the cooperation of the slider 172, the baffle plate 16 can be reset to block the moving groove 15 again.

[0052] It can be known that the length of the inner cavity of the installation groove 18 is greater than the width of the baffle plate 16. By connecting the baffle plate 16 and the housing 1 through the spring 171, the slider 172 and the installation groove 18, the moved baffle plate 16 can be reset automatically and cannot be manually reset, reducing the operation steps of the user and improving work efficiency.

[0053] Embodiment 3: The basic content is the same as that of Embodiment 1, except that: Please refer to Figures 10 - 11, on one side of the first end cap 22 and the second end cap 23 close to the housing 1 in this embodiment, an abutting portion 24 is formed. The abutting portion 24 is inserted into the housing 1. An inner sleeve 3 located inside the housing 1 is abutted between the two abutting portions 24. The abutting portion 24 is used to position the inner sleeve 3, and the inner sleeve 3 is detachably arranged inside the housing 1.

[0054] It should be noted that the internal structure of the motor is arranged inside the inner sleeve 3. The internal structure of the motor is installed in the housing 1 through the inner sleeve 3, which can avoid the need to reinstall the internal structure of the motor when replacing the housing 1, simplifies the steps during the assembly of the motor, and modularizes the internal structure of the motor through the inner sleeve 3, realizing the quick installation of the motor structure.

[0055] Further, please refer to Figure 11 , a limiting groove 313 is opened on the inner sleeve 3 along the y-axis direction. A limiting portion is formed on the inner wall of the housing 1 corresponding to the limiting groove 313. The limiting portion is slidably connected to the limiting groove 313 and limits the rotation of the inner sleeve 3 inside the housing 1. The inner sleeve 3 includes a first sleeve 31 and a second sleeve 32. The limiting groove 313 is opened on the first sleeve 31. The cross-sections of the first sleeve 31 and the second sleeve 32 are both arc-shaped. The first sleeve 31 and the second sleeve 32 are abutted against each other, and a first abutting area 311 and a second abutting area 321 are respectively formed at the abutted parts. A connecting portion 312 is formed at the part of the first sleeve 31 corresponding to the first abutting area 311, and a connecting groove 322 is formed at the part of the second sleeve 32 corresponding to the second abutting area 321. The connecting portion 312 is inserted into the connecting groove 322.

[0056] It should be noted that when the inner sleeve 3 is installed in the housing 1, it is necessary to align the limiting block 19 with the limiting groove 212. Through the cooperation of the limiting block 19 and the limiting groove 313, the situation that the inner sleeve 3 installed in the housing 1 rotates can be avoided, so that the internal structure of the motor inside the inner sleeve 3 can be more stable during installation, and the installed inner sleeve 3 is also positioned by the abutting portions 24 on the first end cap 22 and the second end cap 23, thereby improving the installation stability.

[0057] It should also be noted that the internal structure of the motor includes a stator unit and a rotor unit. The stator unit and the rotor unit are detachably arranged inside the inner sleeve 3. When installing the stator unit and the rotor unit in the inner sleeve 3, separate the first sleeve 31 and the second sleeve 32, then install the stator unit and the rotor unit in the first sleeve 31, and then close the second sleeve 32 and the first sleeve 31, then the stator unit and the rotor unit can be assembled in the inner sleeve 3. And when the first sleeve 31 and the second sleeve 32 are connected, the initial connection can be realized through the cooperation of the connecting portion 312 and the connecting groove 322, so as to facilitate the installation of the inner sleeve 3 composed of the first sleeve 31 and the second sleeve 32 in the housing 1.

[0058] It should be noted that both the stator unit and the rotor unit are modularly arranged, and the two are detachably arranged in the inner sleeve 3. The modular arrangement also facilitates replacement according to different usage scenarios of the motor, thereby reducing the cost for users. Users do not need to purchase different motors for different scenarios. Moreover, the first set 31, the second set 32, the modular stator unit, and the rotor unit cooperate with each other, making replacement even more convenient. Coupled with the modular arrangement of the housing 1, the overall modular arrangement of the motor is achieved, and the assembly efficiency of the motor is also significantly improved.

[0059] It can be known that first, the stator unit and the rotor unit are installed in the first set 31. The stator unit and the rotor unit are in an open state, and it is more convenient to install the stator unit and the rotor unit, providing a larger operating space for the installation of the stator unit and the rotor unit. When installing the stator unit and the rotor unit in the first set 31, the structure connected to the second set 32 can be set in advance, so that the corresponding structures on the stator unit and the rotor unit can be conveniently connected to the corresponding parts on the second set 32.
