Description

Technical Field

[0001] The present invention relates to an axial flux motor, in particular to a flat axial flux motor with a flexible structure, belonging to the technical field of axial flux motors. Background Art

[0002] The flattened axial flux motor, also known as a "disc motor," is a special type of motor with a compact, flat, and ultra-thin structure. The magnetic flux direction of an axial flux motor is axial, and the current-carrying conductors are placed radially. Therefore, the stator and rotor cores are disc-shaped, the air gap is planar, and the air gap magnetic field is axial. Conventional motors have a concentric nested structure with the rotor inside and the stator outside, while the stator of an axial flux motor is on a flat substrate and the rotor above the stator. The stator structure is generally a coil, and the rotor is a permanent magnet. Based on the number of stators and rotors, their relative positions, and the main magnetic circuit classification, the basic topological structures of axial flux motors can be divided into a single-stator-single-rotor structure, a dual-stator-single-rotor structure, a single-stator-dual-rotor structure, and a multi-disc structure.

[0003] The working principle of the axial flux motor is to control the magnetic field strength and direction of the coil by changing the direction and magnitude of the current passing through the coil. Since the stator's magnetic poles are fixed, when the direction and strength of the rotor's magnetic field change, the magnetic field interacts to generate a Lorentz force, thereby driving the rotor to rotate. However, during operation, the direction and strength of the magnetic field will change due to the influence of various factors such as current, temperature, and load. Traditional rigid rotor bracket designs are often based on fixed magnetic field conditions and operating conditions. It is difficult to fully adapt to the dynamic changes in the direction and strength of the magnetic field, which in turn affects the performance and stability of the motor. This is especially true under high loads, high speeds, or complex operating conditions. This inadaptability is often more obvious.

[0004] Due to its unique structural design, the axial flux motor offers significant advantages in multiple fields. First, its flat design makes it unparalleled in space-constrained applications, such as drones, electric vehicles, and medical devices. Second, its high torque density enables it to deliver higher torque output than traditional motors within the same footprint, which is particularly important in high-performance industrial applications.

[0005] In terms of structural design, the stator of an axial flux motor is typically constructed from stacked high-permeability silicon steel sheets to reduce eddy current losses and increase magnetic flux density. The stator winding utilizes a centralized winding, which, compared to the distributed windings of traditional motors, allows for more efficient space utilization and a higher slot fill rate. The rotor utilizes permanent magnets, typically made of high-performance magnetic materials such as neodymium iron boron, to ensure the strength and stability of the magnetic field. The rotor's permanent magnets are mounted on a flexible mesh. This flexible structure allows the magnets to undergo slight angular deflections as the magnetic field changes, thereby better adapting to dynamic changes in the magnetic field.

[0006] During operation, an axial flux motor generates a rotating magnetic field by precisely controlling the current in the stator windings. This rotating magnetic field interacts with the magnetic field of the rotor's permanent magnets, generating a Lorentz force that drives the rotor. Because the direction and strength of the magnetic field are affected by multiple factors, such as current, temperature, and load, traditional rigid rotor bracket designs often struggle to maintain optimal magnetic field alignment in the face of these dynamic changes, resulting in reduced motor performance. To address this issue, a flattened axial flux motor with a flexible structure was proposed. Summary of the Invention

[0007] In light of this, the present invention provides a flattened axial flux motor with a flexible structure to address or alleviate the technical problems existing in the prior art. The flexible structural design of the present invention enables the motor to adapt to dynamically changing magnetic fields. This adaptability not only improves the motor's operating efficiency but also enhances its stability under complex operating conditions. This design can significantly improve the motor's performance, particularly in applications with frequent load changes, such as industrial robots and electric vehicles.

[0008] The synergy between the flexible mesh and support springs is key to achieving adaptive motor performance. When pushed by the magnets, the flexible mesh dynamically adjusts through the interaction of the sliding base and support springs. The elastic properties of the support springs ensure that the magnets quickly reset after deflection, maintaining optimal magnetic field alignment. This design not only improves the motor's dynamic response but also extends the life of the magnets. This offers at least one beneficial option.

[0009] The technical solution of an embodiment of the present invention is implemented as follows: a flat axial flux motor with a flexible structure includes a rotor assembly, which includes a flexible net, two silicone flexible layers, a rotor frame, a connecting seat, a support sleeve, a sliding seat and a support spring.

[0010] The two silicone flexible layers are symmetrically bonded to both sides of the rotor frame, the two flexible nets are symmetrically fixedly connected to the distant surfaces of the two silicone flexible layers, the two flexible nets are fixedly connected through the connecting seat, the sliding seat is slidably connected to the inner side wall of the support sleeve, the support spring is located inside the support sleeve, one end of the support sleeve is fixedly connected to the outer side wall of the rotor frame, the end of the sliding seat away from the support sleeve is hinged to one side of the flexible net through a ball head, the two ends of the support spring respectively support the support sleeve and the sliding seat, the rotor frame is a hollow structure, the outer side wall of the flexible net is symmetrically fixedly connected to the mounting seat, and the interior of the mounting seat is embedded with a magnetic steel.

[0011] The flexible mesh is made of high-strength, corrosion-resistant materials, ensuring structural stability and flexibility in dynamically changing magnetic fields. The mesh structure not only reduces overall weight but also allows the magnets to freely shift within a certain range, better adapting to changes in magnetic field direction and intensity. This allows the magnet angle to be dynamically adjusted during motor operation, ensuring optimal magnetic field alignment, thereby improving motor efficiency and stability.

[0012] Further preferably, the support sleeve and the sliding seat are both embedded within the silicone flexible layer, and the sliding seat is slidably connected to the interior of the silicone flexible layer. Silicone material has excellent elasticity and temperature resistance, and can remain stable in both high and low temperature environments. The silicone flexible layer not only provides a good seal for the support sleeve and sliding seat, but also absorbs vibration and impact generated during operation, thereby extending the service life of the motor. Furthermore, the elastic properties of the silicone flexible layer enable the sliding seat to achieve smooth sliding under the action of the support spring, ensuring more precise dynamic adjustment of the magnet.

[0013] Further preferably, the rotor assembly further includes a connecting frame, a limiting seat, a limiting groove, a rotor shaft, a limiting block, a fixing ring and a retaining ring.

[0014] One end of the connecting frame is fixedly connected to the inner side wall of the rotor frame, and the other end of the connecting frame is fixedly connected to the outer side wall of the limit seat. The limit groove is symmetrically opened on the inner side wall of the limit seat. The limit block and the fixing ring are both fixedly connected to the outer side wall of the rotor shaft, and the retaining ring is slidably connected to the outer side wall of the rotor shaft.

[0015] The combined design of the connecting frame and stopper ensures a secure installation of the rotor frame, while the combination of the stopper slot and stopper block effectively prevents axial displacement of the rotor shaft during operation. The design of the retaining ring and retaining ring further enhances the stability of the rotor shaft, ensuring it does not wobble even at high speeds. Furthermore, the retaining ring's sliding connection design facilitates rotor shaft disassembly and maintenance, reducing maintenance costs.

[0016] Further preferably, the limiting seat is sleeved on the outer side wall of the rotor shaft and is slidably connected to the rotor shaft, and the limiting block is slidably connected to the inner side wall of the limiting groove.

[0017] This design allows for fine-tuning of the rotor shaft's axial direction during operation to adapt to varying load conditions. The symmetrical design of the limit slots ensures the limit blocks remain balanced during sliding, preventing unbalanced torque caused by offset. This dynamic adjustment capability ensures stable motor performance even under complex operating conditions.

[0018] Further preferably, adjacent surfaces of the retaining ring and the fixing ring are symmetrically fitted to the outer side wall of the limiting seat, and through holes are provided inside the retaining ring, the fixing ring and the limiting seat.

[0019] Further preferably, a positioning bolt is provided inside the through hole, and the retaining ring, the fixing ring and the limiting seat are fixedly connected by the positioning bolt.

[0020] The positioning bolt design ensures a more secure and reliable connection between the retaining ring, retaining ring, and stopper. During operation, the positioning bolts effectively prevent loosening between components, ensuring the overall stability of the rotor assembly. Furthermore, this design facilitates disassembly and maintenance; maintenance personnel simply remove the positioning bolts to easily access the relevant components, significantly improving maintenance efficiency.

[0021] Further preferably, a stator assembly is provided outside the rotor assembly, and the stator assembly includes two casings, two stator cores and a stator winding.

[0022] The two casings are fixedly connected by connecting bolts, the stator core is installed inside the casing, and the stator winding is wound inside the stator core.

[0023] The housing is constructed of high-strength aluminum alloy, providing both excellent mechanical strength and heat dissipation. The stator core is constructed of laminated silicon steel sheets with high magnetic permeability, effectively reducing eddy current losses and improving motor efficiency. The stator winding is wound with high-strength insulating enameled wire, ensuring stable operation at high currents and frequencies.

[0024] Further preferably, the two stator cores are symmetrically located on both sides of the rotor frame, and the rotor assembly is located inside the casing.

[0025] The symmetrical design of the stator core ensures a more uniform magnetic field distribution within the motor, thereby improving its operating efficiency and stability. The rotor assembly is located within the housing, and precise clearance design ensures a uniform air gap between the rotor and stator, further optimizing magnetic field coupling.

[0026] Further preferably, two bearings are symmetrically mounted on the outer side wall of the rotor shaft, and the rotor shaft is rotatably connected to the inside of the two casings through the two bearings.

[0027] High-precision deep groove ball bearings are used to withstand combined radial and axial loads, ensuring smooth rotation of the rotor shaft. The symmetrical mounting design of the bearings ensures uniform force on the rotor shaft during operation, avoiding vibration and noise caused by uneven loading.

[0028] Further preferably, a circuit box is installed on the outer side wall of the casing.

[0029] The circuit box is designed to house the motor's wiring terminals and control circuits, ensuring safe and reliable electrical connections. Its waterproof and dustproof design protects the internal electrical components from harsh environments. Furthermore, it provides standardized interfaces for easy connection to external control systems, enabling intelligent control.

[0030] The embodiment of the present invention adopts the above technical solution, which has the following advantages: During the operation of the present invention, under the influence of various factors such as current, temperature, and load, the direction and intensity of the magnetic field change, and the magnet is subjected to a force. At this time, the magnet pushes the flexible net through the mounting seat, and the flexible net drives the sliding seat. The sliding seat slides in the support sleeve, and the support spring is compressed by the force. Then, the angle of the magnet can be automatically offset to better adapt to the dynamic changes in the direction and intensity of the magnetic field, thereby ensuring the performance and stability of the axial flux motor. When the direction and intensity of the magnetic field are normal, the support spring and the silicone flexible layer can push the magnet to reset, thereby ensuring the stability of the structure.

[0031] The flexible structural design of this invention enables the motor to adapt to dynamically changing magnetic fields. This adaptability not only improves the motor's operating efficiency but also enhances its stability under complex operating conditions. This design can significantly enhance motor performance, particularly in applications with frequently fluctuating loads, such as industrial robots and electric vehicles.

[0032] The synergy between the flexible mesh and support springs is key to achieving adaptive capability. When pushed by the magnets, the flexible mesh dynamically adjusts through the interaction of the sliding seat and support springs. The elastic properties of the support springs ensure that the magnets quickly reset after deflection, maintaining optimal magnetic field alignment. This design not only improves the motor's dynamic response but also extends the life of the magnets.

DETAILED DESCRIPTION

[0037] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be considered as illustrative in nature and not restrictive.

[0038] The heat dissipation design of axial flux motors is also crucial. Since motors generate significant heat when operating under high load, failure to dissipate this heat can affect motor performance or even damage it. To this end, the motor casing is constructed of high-strength aluminum alloy, which not only provides excellent mechanical strength but also outstanding heat dissipation. Heat dissipation channels are designed into the casing, and external cooling fins are added to enhance heat dissipation. Furthermore, an intelligent temperature control system is introduced, using temperature sensors to monitor the internal motor temperature in real time. If the temperature is too high, the cooling fan automatically activates, ensuring the motor maintains optimal operating condition under all operating conditions.

[0039] The reliability and durability of axial flux motors have been fully demonstrated in practical applications. Long-term operational tests and simulated harsh operating conditions have verified the motor's stability and reliability under various extreme conditions. These test results demonstrate that this motor meets the requirements of industrial-grade applications and has a long service life.

[0040] In the future, advancements in materials science and intelligent manufacturing will further optimize axial flux motors. For example, the use of new composite materials can further reduce weight and improve strength; the introduction of intelligent sensors and control systems can achieve more precise dynamic adjustments; and modular design can meet diverse application needs, thereby promoting the development of the robotics and electric equipment industries.

[0043] The two silicone flexible layers 14 are symmetrically bonded to both sides of the rotor frame 15, the two flexible nets 13 are symmetrically fixedly connected to the distant surfaces of the two silicone flexible layers 14, the two flexible nets 13 are fixedly connected through the connecting seat 16, the sliding seat 25 is slidably connected to the inner wall of the support sleeve 24, the support spring 26 is located inside the support sleeve 24, one end of the support sleeve 24 is fixedly connected to the outer wall of the rotor frame 15, the end of the sliding seat 25 away from the support sleeve 24 is hinged to one side of the flexible net 13 through a ball head, the two ends of the support spring 26 respectively support the support sleeve 24 and the sliding seat 25, the rotor frame 15 is a hollow structure, the outer wall of the flexible net 13 is symmetrically fixedly connected with the mounting seat 12, and the interior of the mounting seat 12 is embedded with a magnetic steel 11.

[0044] The flexible mesh 13 is made of high-strength, corrosion-resistant materials, ensuring structural stability and flexibility in dynamically changing magnetic fields. The mesh structure of the flexible mesh 13 not only reduces overall weight but also allows the magnets 11 to freely shift within a certain range, better adapting to changes in magnetic field direction and intensity. This design allows the angle of the magnets 11 to be dynamically adjusted during motor operation, ensuring optimal magnetic field alignment and improving motor efficiency and stability.

[0045] In one embodiment, the support sleeve 24 and the sliding seat 25 are both embedded in the interior of the silicone flexible layer 14 , and the sliding seat 25 is slidably connected to the interior of the silicone flexible layer 14 .

[0046] Silicone material has excellent elasticity and temperature resistance, maintaining stability in both high and low temperature environments. The flexible silicone layer 14 not only provides a good seal between the support sleeve 24 and the sliding seat 25, but also absorbs vibration and shock generated during operation, thereby extending the life of the motor. Furthermore, the elastic properties of the flexible silicone layer 14 enable the sliding seat 25 to slide smoothly under the action of the support spring 26, ensuring more precise dynamic adjustment of the magnet 11.

[0047] In one embodiment, the rotor assembly 101 further includes a connecting frame 17 , a limiting seat 18 , a limiting groove 19 , a rotor shaft 20 , a limiting block 21 , a fixing ring 22 and a retaining ring 23 .

[0048] One end of the connecting frame 17 is fixedly connected to the inner side wall of the rotor frame 15, and the other end of the connecting frame 17 is fixedly connected to the outer side wall of the limit seat 18. The limit groove 19 is symmetrically opened on the inner side wall of the limit seat 18. The limit block 21 and the fixing ring 22 are both fixedly connected to the outer side wall of the rotor shaft 20. The retaining ring 23 is slidably connected to the outer side wall of the rotor shaft 20. The limit seat 18 is sleeved on the outer side wall of the rotor shaft 20 and is slidably connected to the rotor shaft 20. The limit block 21 is slidably connected to the inner side wall of the limit groove 19. The position of the limit seat 18 can be limited by the cooperation of the limit block 21 and the limit groove 19.

[0049] The structural design of rotor assembly 101 fully considers operational stability and maintainability. The combined design of connecting frame 17 and retaining seat 18 ensures the secure installation of rotor frame 15. The cooperation between retaining groove 19 and retaining block 21 effectively prevents axial displacement of rotor shaft 20 during operation. The design of retaining ring 22 and retaining ring 23 further enhances the stability of rotor shaft 20, ensuring that it does not wobble during high-speed rotation. Furthermore, the sliding connection design of retaining ring 23 facilitates the disassembly and maintenance of rotor shaft 20, reducing maintenance costs.

[0050] In one embodiment, the adjacent surfaces of the retaining ring 23 and the fixing ring 22 are symmetrically fitted to the outer wall of the limit seat 18, and the interiors of the retaining ring 23, the fixing ring 22 and the limit seat 18 are all provided with through holes 29, and the interiors of the through holes 29 are provided with positioning bolts 28, and the retaining ring 23, the fixing ring 22 and the limit seat 18 are fixedly connected by the positioning bolts 28.

[0051] The design of retaining bolts 28 ensures a more secure and reliable connection between retaining ring 23, retaining ring 22, and stopper 18. During operation, retaining bolts 28 effectively prevent loosening between components, ensuring the overall stability of rotor assembly 101. Furthermore, this design facilitates disassembly and maintenance; maintenance personnel simply unscrew retaining bolts 28 to easily remove the relevant components, significantly improving maintenance efficiency.

[0052] In one embodiment, a stator assembly 301 is disposed outside the rotor assembly 101 . The stator assembly 301 includes two housings 31 , two stator cores 32 and a stator winding 33 .

[0053] The two casings 31 are fixedly connected by connecting bolts, the stator core 32 is installed inside the casing 31, the stator winding 33 is wound inside the stator core 32, the two stator cores 32 are symmetrically located on both sides of the rotor frame 15, and the rotor assembly 101 is located inside the casing 31.

[0054] The housing 31 is made of high-strength aluminum alloy, providing excellent mechanical strength and heat dissipation. The stator core 32 is constructed from laminated silicon steel sheets with high magnetic permeability, effectively reducing eddy current losses and improving motor efficiency. The stator winding 33 is wound with high-strength insulating enameled wire to ensure stable operation at high currents and frequencies.

[0055] In one embodiment, the two stator cores 32 are symmetrically located on both sides of the rotor frame 15 , and the rotor assembly 101 is located inside the housing 31 .

[0056] The symmetrical design of the stator core 32 makes the motor's magnetic field distribution more uniform, thereby improving the motor's operating efficiency and stability. The rotor assembly 101 is located inside the housing 31. Through precise gap design, the air gap between the rotor and stator is uniform, further optimizing the magnetic field coupling effect.

[0057] In one embodiment, two bearings 27 are symmetrically mounted on the outer side wall of the rotor shaft 20 , and the rotor shaft 20 is rotatably connected to the inside of the two casings 31 via the two bearings 27 .

[0058] The present invention uses high-precision deep groove ball bearings that can withstand combined radial and axial loads, ensuring smooth rotation of the rotor shaft 20. The symmetrical mounting design of the bearings 27 ensures that the rotor shaft 20 is evenly loaded during operation, avoiding vibration and noise caused by uneven loading.

[0059] In one embodiment, a circuit box 34 is installed on the outer wall of the housing 31 .

[0060] Circuit Box 34 is designed to house the motor's wiring terminals and control circuits, ensuring safe and reliable electrical connections. Its waterproof and dustproof design protects the internal electrical components from harsh environments. Furthermore, it provides standardized interfaces for easy connection to external control systems, enabling intelligent control.

[0061] The embodiment of the present invention adopts the above technical solution, which has the following advantages: During operation of the present invention, under the influence of various factors such as current, temperature, and load, the direction and intensity of the magnetic field change, and the magnet 11 is subjected to a force. At this time, the magnet 11 pushes the flexible net 13 through the mounting seat 12, and the flexible net 13 drives the sliding seat 25. The sliding seat 25 slides in the support sleeve 24, and the support spring 26 is compressed by the force. At this time, the angle of the magnet 11 can be automatically offset to better adapt to the dynamic changes in the direction and intensity of the magnetic field, thereby ensuring the performance and stability of the axial flux motor. When the direction and intensity of the magnetic field are normal, the support spring 26 and the silicone flexible layer 14 can push the magnet 11 to reset, thereby ensuring the stability of the structure.

[0062] The flexible structural design of this invention enables the motor to adapt to dynamically changing magnetic fields. This adaptability not only improves the motor's operating efficiency but also enhances its stability under complex operating conditions. This design can significantly enhance motor performance, particularly in applications with frequently fluctuating loads, such as industrial robots and electric vehicles.

[0063] The synergy between the flexible mesh 13 and the support spring 26 is key to achieving adaptive performance. When pushed by the magnet 11, the flexible mesh 13 dynamically adjusts through the interaction of the sliding seat 25 and the support spring 26. The elastic properties of the support spring 26 ensure that the magnet 11 quickly resets after deflection, maintaining optimal magnetic field alignment. This design not only improves the motor's dynamic response but also extends the life of the magnet 11.

[0064] Furthermore, the flat design of the present invention enables the motor to be smaller and lighter while maintaining high performance. This has important practical implications for space-constrained applications such as drones and medical equipment. The flat design also reduces the motor's manufacturing cost, improving its market competitiveness.

[0065] In practical applications, the axial flux motor of the present invention can be widely used in industrial robots, electric vehicles, drones, medical equipment, and other fields. For example, in industrial robots, the motor's high torque output and precise control capabilities can meet the dynamic requirements of joint modules; in electric vehicles, the motor's high efficiency and lightweight design help improve endurance and power performance; and in medical equipment, the motor's stability and low noise characteristics can provide a more comfortable user experience.

[0066] Since the motor generates a lot of heat when running at high load, if the heat is not dissipated in time, it may affect the performance of the motor or even cause damage. To this end, we have designed a heat dissipation channel inside the housing 31 and added heat dissipation fins outside the housing 31 to enhance the heat dissipation effect.

[0067] When the present invention is working: the axial magnetic field motor is connected to an external power supply through the circuit box 34. At this time, current passes through the stator winding 33 and generates a magnetic field. This magnetic field interacts with the magnetic steel 11, thereby driving the rotor shaft 20 to rotate, converting electrical energy into mechanical energy, and driving the load to operate. During operation, under the influence of various factors such as current, temperature, and load, the direction and intensity of the magnetic field change, and the magnetic steel 11 is subjected to a force. At this time, the magnetic steel 11 pushes the flexible net 13 through the mounting seat 12, and the flexible net 13 pushes the silicone flexible layer 14 and the sliding seat 25. The sliding seat 25 slides in the support sleeve 24, and the support spring 26 is compressed by the force. At this time, the angle of the magnetic steel 11 can be automatically offset, thereby better adapting to the dynamic changes in the direction and intensity of the magnetic field, realizing flexible adjustment. When the direction and intensity of the magnetic field are normal, the support spring 26 and the silicone flexible layer 14 can push the magnetic steel 11 to reset, thereby ensuring the stability of the structure; When repairing the rotor, the casing 31 is removed, the rotor is taken out, the positioning bolts 28 are removed, the retaining ring 23 is taken out, and the limit seat 18 is separated from the rotor shaft 20. At this time, the rotor is disassembled, which facilitates the repair of the rotor.

[0068] A flat axial flux motor with a flexible structure addresses the shortcomings of traditional motors in terms of dynamic adaptability and structural stability, providing a new technological path for the development of the motor industry. With the continuous advancement of technology, the research and application prospects in this field will be even broader.
