Existing frameless motors typically utilize a permanent magnet synchronous motor design, where the stator and rotor are mechanically connected (such as bolts or clips) and installed in robot joints or drive units to provide precise power output. However, the disassembly and assembly process of traditional frameless motors is complex, requiring specialized tools and a long time, increasing maintenance difficulties. Furthermore, the stator's fixed position prevents flexible air gap adjustment, leading to high assembly alignment requirements and difficulty adapting to varying performance requirements. These issues are particularly prominent in scenarios where robots require frequent maintenance or rapid component replacement, limiting production efficiency and application flexibility.

[0003] The main drawbacks of existing frameless motors include: complex assembly and disassembly processes requiring specialized tools, which is time-consuming and increases maintenance costs. The fixed stator position prevents flexible air gap adjustment, leading to high alignment requirements and operational difficulties during assembly. Furthermore, the rigid design of the stator structure makes it difficult to adapt to varying performance requirements, limiting the motor's flexibility in diverse robotic applications. These issues significantly impact production efficiency and ease of maintenance. Summary of the Invention

[0017] The advantages and beneficial effects of the present invention compared to the prior art are as follows:

[0018] 1. The present invention realizes the rapid disassembly and assembly of the frameless motor through the electromagnetic locking mechanism, which significantly improves the operational efficiency. Traditional frameless motors rely on bolts or clips for fixation, and disassembly and assembly require special tools and are time-consuming. The electromagnetic locking mechanism of the present invention controls the telescopic rod and the fixed block through electrical signals, and only needs to turn on or off the power to complete the locking and unlocking of the rotor, without the need for mechanical tools. This design is particularly suitable for scenarios in the field of robotics that require frequent maintenance, such as the joint drive units of collaborative robots or industrial robotic arms. Rapid disassembly and assembly not only shortens downtime, but also reduces maintenance costs, improves the operating efficiency of the production line, and facilitates the rapid deployment and maintenance of the robotic system.

[0019] 2. The radially adjustable stator core assembly of the present invention significantly enhances assembly flexibility. Traditional frameless motors have fixed stators, requiring high-precision alignment during assembly, which is difficult to operate. The present invention allows the stator core assembly to move radially along the adjustment tube, expanding the internal space during assembly to facilitate rotor insertion; after completion, it is adjusted to the optimal air gap to improve performance. This flexibility reduces assembly alignment requirements and is suitable for rotors of different sizes or diverse robot application scenarios. At the same time, the adjustment holes and screw fixing method are simple to operate, ensuring the accuracy and stability of the adjustment, and providing support for mass production and personalized customization.

[0020] 3. This invention optimizes the motor's performance adaptability through an adjustable stator design, meeting the diverse needs of the robotics field. Conventional frameless motors have a fixed air gap, making them difficult to adapt to varying power or efficiency requirements. However, the stator core assembly of this invention can be fine-tuned to optimize the air gap and magnetic field distribution, improving motor efficiency and output characteristics. This performance adjustment capability is suitable for diverse robotic operating conditions, such as high-torque industrial manipulators or high-precision service robots. Furthermore, the integrated control electromagnet and windings on the PCB further enhance system responsiveness and stability, providing technical support for optimizing motor performance in complex robotic applications.

The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0034] See also Figures 1 to 11 A motor that is easy to disassemble and assemble includes a stator module 1, a support unit 101, and a plurality of stator core assemblies 102 movably arranged inside the support unit 101. The plurality of stator core assemblies 102 are distributed in an annular shape, and the stator core assemblies 102 can be adjusted in the radial direction of the support unit 101.

An upper end cover 104 is sealed at one end of the support unit 101, and a circular groove portion 105 is provided on the upper end cover 104; a rotor module 2 includes a rotor body 201, and the outer wall of the rotor body 201 is provided with a plurality of stator core assemblies 103. 2 matching permanent magnets 202, the circular end surface of the rotor body 201 is provided with an extension portion 203 extending outward, and a plurality of limit openings 204 are equidistantly provided on the side of the extension portion 203; the locking mechanism 3 provided on the circular groove portion 105 includes a telescopic rod 303, one end of which is fixed with an iron block 304, and the other end of the telescopic rod 303 is elastically connected to a fixed block 306 via a compression spring 305, and the size of the fixed block 306 matches and corresponds to the limit opening 204; the locking mechanism 3 also includes a fixed cylinder 307, which is provided with an electromagnet 308, and the iron block 304 is placed in the fixed cylinder 307.

[0035] In this embodiment, the goals of rapid assembly and disassembly and high flexibility are achieved through the coordinated design of the stator module 1, the rotor module 2 and the locking mechanism 3. The stator module 1 includes a support unit 101 and a radially adjustable stator core assembly 102. The position adjustment is achieved by adjusting the cylinder 101b and the screw 101c, which facilitates rotor insertion and air gap optimization, reduces assembly difficulty and improves performance adaptability. The permanent magnet 202 of the rotor module 2 matches the stator core assembly 102, and the limit opening 204 on the extension 203 cooperates with the locking mechanism 3 to ensure that the rotor is stably fixed. The locking mechanism 3 uses an electromagnet 308 to control the telescopic rod 303 and the fixed block 306, and quickly locks or unlocks the rotor by powering on / off, without the need for tools, significantly shortening the assembly and disassembly time. This structure is particularly suitable for the field of robotics, taking into account the needs of efficient maintenance, flexible assembly and performance optimization.

[0036] Preferably, the stator module 1 further includes a PCB 106 arranged at the other end of the support unit 101 and a lower end cover 107 arranged outside the PCB 106 . The lower end cover 107 and the support unit 101 are sealed together, and the PCB 106 is electrically connected to the stator winding 103 and the electromagnet 308 .

[0037] In this embodiment, by adding PCB106 and lower end cover 107 to the stator module 1, the functional integration and environmental adaptability are further improved. PCB106 is arranged at the other end of the support unit 101, electrically connected to the stator winding 103 and the electromagnet 308, to achieve centralized control of the motor operation and the locking mechanism 3, simplify the circuit layout, and improve the response speed and system stability. The lower end cover 107 is sealed with the support unit 101 to protect the PCB106 and internal components from external factors such as dust and moisture, thereby enhancing the durability of the motor in complex environments such as robots. This design, combined with the electromagnetic locking mechanism 3 and the adjustable stator core assembly 102, not only facilitates rapid disassembly and assembly and performance optimization, but also improves the reliability and intelligence level of the motor, and is particularly suitable for efficient and precise robot application scenarios.

[0038] Preferably, the support unit 101 includes a cylinder 101 a , a plurality of adjustment cylinders 101 b are equidistantly arranged on the inner side of the cylinder 101 a , and screws 101 c are used to fix the cylinder 101 a and the stator core assembly 102 .

[0039] In this embodiment, the specific design of the support unit 101 enhances the adjustment flexibility and fixation reliability of the stator core assembly 102. The support unit 101 includes a cylinder 101a, and a number of adjustment cylinders 101b equidistantly arranged on the inner side thereof provide a radial movement track for the stator core assembly 102, allowing the internal space to be expanded during assembly to facilitate rotor insertion, or adjusted to the optimal air gap during operation to optimize performance. The screw 101c is used to fix the cylinder 101a and the stator core assembly 102, and precise positioning and firm connection are achieved through the adjustment hole 102c, which is simple and stable to operate. This structure, in conjunction with the electromagnetic locking mechanism 3, significantly reduces the difficulty of assembly and maintenance time, improves the flexibility and efficiency of the motor in the field of robotics, and is particularly suitable for scenarios that require rapid disassembly and performance adjustment.

[0040] Preferably, the stator core assembly 102 includes an adjustment block 102a, which is movably arranged inside the adjustment cylinder 101b and can move radially along the cylinder 101a. A plurality of adjustment holes 102c are opened on the surface of the adjustment block 102a, and a limit block 102b is fixed at one end of the adjustment block 102a close to the center of the cylinder 101a.

[0041] In this embodiment, the preferred structure of the motor that is easy to disassemble and assemble significantly improves the assembly flexibility and performance adjustment capability through the design of the stator core assembly 102. The stator core assembly 102 includes an adjustment block 102a, which is movably arranged in the adjustment cylinder 101b and can move radially along the cylinder 101a, allowing the internal space of the stator to be expanded during assembly to facilitate the insertion of the rotor, or fine-tuning the air gap during operation to optimize the motor performance. The adjustment hole 102c on the surface of the adjustment block 102a cooperates with the screw 101c to achieve precise fixation and ensure position stability. The limit block 102b is fixed at one end close to the center of the cylinder 101a to prevent excessive displacement of the adjustment block and ensure structural safety. This design, combined with the electromagnetic locking mechanism 3, reduces the difficulty of assembly and alignment, improves maintenance efficiency, and is particularly suitable for the needs of the robotics field for rapid disassembly and high performance.

[0042] Preferably, the locking mechanism 3 also includes a first fixing fastener 301, which is fixed on the top surface of the circular groove portion 105, and a limiting cylinder 302 is fixed on the first fixing fastener 301. The telescopic rod 303 is movably sleeved in the limiting cylinder 302 and the telescopic rod 303 can move axially along the limiting cylinder 302; it also includes a second fixing fastener 309, which is fixedly arranged on the top surface of the circular groove portion 105 and fixed between the second fixing fastener 309 and the fixed cylinder 307.

[0043] In this embodiment, the locking mechanism 3 significantly improves the stability and operational convenience of the locking function by adding a first fixing fastener 301, a limiting cylinder 302, and a second fixing fastener 309. The first fixing fastener 301 is fixed to the top of the circular groove portion 105, supporting the limiting cylinder 302, so that the telescopic rod 303 can move precisely axially within the limiting cylinder 302, ensuring the accurate alignment of the fixed block 306 and the rotor limiting opening 204. The second fixing fastener 309 fixes the fixing cylinder 307, stabilizes the relative position of the electromagnet 308 and the iron block 304, and ensures the reliability of electromagnetic locking. This structure achieves rapid locking / unlocking through electromagnetic control, and combined with the adjustable stator design, reduces the difficulty and time of disassembly and assembly, and is particularly suitable for the needs of efficient maintenance and rapid assembly in the field of robotics.

[0044] Preferably, the limiting cylinder 302 includes a cylindrical body 302a, and a plurality of limiting strips 302b are provided inside the cylindrical body 302a.

[0045] In this embodiment, the limiting cylinder 302 structure, through the cylindrical body 302a and several internal limiting strips 302b, significantly enhances the motion stability and precision of the locking mechanism 3. The cylindrical body 302a, serving as the main body of the limiting cylinder 302, provides a channel for axial movement of the telescopic rod 303. The limiting strips 302b cooperate with the limiting grooves 303b on the surface of the telescopic rod 303 to restrict the rotation of the telescopic rod 303, ensuring that it moves only in the axial direction, thereby ensuring precise alignment of the fixed block 306 with the rotor limiting opening 204. This design improves the operational reliability of the electromagnetic locking mechanism and reduces the risk of misoperation. Combined with the quick assembly and disassembly function, it significantly improves the efficiency of motor maintenance and assembly in the robotics field, meeting the application requirements of high precision and rapid response.

[0046] Preferably, the telescopic rod 303 includes a round rod body 303 a , a surface of the round rod body 303 a is provided with a limiting groove 303 b corresponding to the limiting strip 302 b , and a spring fixing disk 303 c corresponding to the compression spring 305 is provided on the round rod body 303 a .

[0047] In this embodiment, the preferred telescopic rod 303 structure of the motor, which is easy to disassemble and assemble, significantly improves the movement accuracy and reliability of the locking mechanism 3 through the design of the round rod body 303a, the limiting groove 303b, and the spring fixing disk 303c. The round rod body 303a serves as the main body of the telescopic rod 303, ensuring the stability of axial movement; the limiting groove 303b cooperates with the limiting bar 302b of the limiting cylinder 302 to limit rotation and ensure the precise alignment of the fixed block 306 and the rotor limiting opening 204. The spring fixing disk 303c provides a stable support point for the compression spring 305, ensuring that the spring applies force evenly during the locking and unlocking process, thereby enhancing the reliability of the electromagnetic locking. This design, combined with the quick disassembly function, reduces maintenance time and operational difficulty, and is particularly suitable for the demand for efficient and precise drive systems in the robotics field.
