Description

Technical Field

[0001] This invention relates to the field of axial flux motor technology, specifically a self-cooling axial flux motor. Background Technology

[0002] According to the direction of the magnetic flux path, motors can be divided into axial flux motors and radial flux motors. An axial flux motor is a motor in which the magnetic flux flows along the axial direction of the motor, that is, along the axis of the motor. It is also commonly referred to as a disc motor or a flat motor.

[0003] Axial flux motors operate based on the stator's magnetic poles being arranged along an axis. The rotor is typically a cylindrical structure, with magnetic flux passing through its central axis. When current flows through the stator windings, the resulting magnetic field passes through the rotor along the axis. According to the Lorentz force law, this magnetic field generates torque in the rotor, driving its rotation. Intelligent electronic controllers and sensors determine the rotor's position and, based on this information, decide which coils to energize to ensure continuous motor rotation. Due to their disc-type structure, axial flux motors are small and lightweight, making them suitable for applications with strict space and weight constraints. They typically have high power density, making them ideal for efficient and compact designs.

[0004] However, during operation, current flows through the windings of an axial flux motor. As the current continues to flow, the resistance in the windings continuously converts electrical energy into heat, generating Joule heating and causing the winding temperature to rise. Simultaneously, the magnetic field inside the motor is constantly changing. This changing magnetic field induces eddy currents in components such as the motor's core. These eddy currents, flowing through the core, also generate heat, further exacerbating the temperature rise inside the motor. When the internal temperature of the motor is too high, the lack of a self-cooling system will degrade the performance of the motor's insulation materials, reducing insulation strength and increasing the risk of short circuits. Prolonged operation in high-temperature environments will also accelerate the wear of mechanical components such as bearings, shortening the motor's lifespan and reducing its reliability and stability.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.

[0036] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0037] Example 1, referring to Figures 1-7 , Figure 12 This invention provides a self-cooled axial flux motor, comprising a rear cover plate 1 and a front cover plate 3. A fixing ring 5 is rotatably connected to the inner wall of both the rear cover plate 1 and the front cover plate 3. A rotor yoke 6 is rotatably connected to the surface of the fixing ring 5. A cover 2 is detachably connected to the surface of the rear cover plate 1. The fixing rings 5 ​​embedded in the rear cover plate 1 and the front cover plate 3 provide stable support for the rotor yoke 6. The rotor yoke 6 rotates on the fixing rings 5 ​​to generate a magnetic field to drive the motor. The cover 2 is detachably connected to the rear cover plate 1 to protect the motor's interior. The invention also includes...

[0038] The turbulence structure includes five sets of sensor bases 7 fixedly connected to the outer wall of the rotor yoke 6 and arranged in a circular pattern on the surface of the rotor yoke 6, a mounting groove 8 opened on the surface of the sensor base 7, and a turbulence assembly rotatably connected inside the mounting groove 8; the mounting groove 8 is used to provide space for the operation of the turbulence assembly.

[0039] The sensor base 7 is used to detect the temperature of the rotor yoke 6 surface and the angle data of the blade 14 deployment. This data is transmitted to the control system. If the temperature rises abnormally or the blade angle deviates from the predetermined range, the control system can issue a fault warning, prompting the operator to check or repair. The control system can also record the data transmitted by the sensor base 7 for subsequent analysis and diagnosis. This data can help engineers understand the motor's operating status and optimize the motor's design and control strategies.

[0040] The turbulence-dissipating components automatically adjust according to the rotor's speed and temperature, thereby optimizing airflow, improving heat dissipation efficiency, and effectively reducing the operating temperature inside the motor.

[0041] The self-cooling structure includes a roll plate 18 fixedly connected to one end of the turbulence assembly, a shift plate 20 fixedly connected to one end of the roll plate 18, a position sensor 19 disposed on the surface of the shift plate 20, and a self-cooling component fixedly connected to the surface of the cover 2 and controlled by the position information of the shift plate 20 sensed by the position sensor 19.

[0042] When the turbulence component is working, it drives the rotation of the winding blade 18, which in turn drives the shift blade 20 to move on the position sensor 19. One end of the shift blade 20 is provided with an anti-detachment block 21 to prevent the shift blade 20 from falling off the position sensor 19. After the position sensor 19 detects the position of the shift blade 20, it outputs a corresponding electrical signal. This signal needs to be transmitted to the control system for processing. The signal transmission is carried out wirelessly. After receiving the signal, the motor control system controls the operation of the self-cooling component to automatically cool the surface of the stator 36, thereby reducing the internal temperature of the motor.

[0043] Optionally, a number of rear filters 33 are fixedly connected to the surface of the rear cover plate 1, and a number of front waterproof meshes 35 are fixedly connected to the surface of the front cover plate 3. Both the front cover plate 3 and the rear cover plate 1 of the motor are designed with vents to promote heat dissipation. The rear cover plate 1 is equipped with rear filters 33 to prevent impurities from entering, while the front cover plate 3 is equipped with front waterproof meshes 35 to prevent moisture intrusion, together ensuring the efficient and safe operation of the motor.

[0044] The turbulence assembly includes a fixed base plate 9, which is fixedly connected to the surface of the rotor yoke 6 at the bottom and to the surface of the mounting groove 8 on the side; two support columns 10, which are fixedly connected to the fixed base plate 9 and are in symmetrical positions; and a connecting plate 12, which is rotatably connected between the two support columns 10. The structure of the fixed base plate 9, support columns 10, connecting plate 12, and elastic plate 11 forms a relatively soft hinge structure, which is used to drive the rotating shaft 13 and blade 14 to rotate on the support columns 10. The angle between the connecting plate 12 and the fixed base plate 9 is the angle between the blade 14 and the surface of the rotor yoke 6.

[0045] The connecting plate 12, at the end furthest from the support column 10, is fixedly connected to a rotating shaft 13. An elastic sheet 11 is fixedly connected between the connecting plate 12 and the fixed base plate 9. A blade 14 is fixedly connected to the surface of the rotating shaft 13. Two connecting seats 15, positioned symmetrically, are fixedly connected to the surface of the blade 14. A fixing seat 17, corresponding to the position of the connecting seat 15, is fixedly connected to the surface of the rotor yoke 6. The fixing seat 17 and the connecting seat 15 are collinear. A shape memory alloy wire 16 is fixedly connected between the fixing seat 17 and the connecting seat 15. The shape memory alloy wire 16 is pre-set with a specific shape and recovery temperature during manufacturing. For example, it can be pre-set that when the temperature reaches 160 degrees Celsius, the shape memory alloy wire 16 will shrink, causing the blade angle to decrease; when the temperature drops to 80 degrees Celsius, the shape memory alloy wire 16 will elongate, causing the blade angle to increase.

[0046] Another function of the sensor base 7 is to monitor the rotor temperature in real time. The signal from the sensor base 7 can be used to calibrate the response of the shape memory alloy 16 wire, ensuring that the adjustment of the blade angle matches the actual temperature change. For example, if the rotor temperature is 160 degrees Celsius, but the preset response temperature of the shape memory alloy 16 wire is 155 degrees Celsius, the motor control system can increase the current to the shape memory alloy 16 wire, raising its phase transition temperature to 160 degrees Celsius, thus ensuring that the adjustment of the blade angle matches the actual temperature change.

[0047] During use, when the internal heat of the motor becomes excessive, the shape memory alloy 16 wire is pre-set to recover its temperature and shape through a heat treatment process. For example, it is pre-set that when the temperature reaches 160 degrees Celsius, the shape memory alloy 16 wire will contract, causing the blade 14 and the shaft 13 to rotate forward on the support column 10, reducing the included angle; when the temperature drops to 80 degrees Celsius, the shape memory alloy 16 wire will elongate, causing the blade 14 and the shaft 13 to rotate in the opposite direction on the support column 10, increasing the included angle of the blades.

[0048] Before starting the motor, the blade angle is set to the initial value. At this time, the shape memory alloy 16 wire is in a natural state without any external force applied. When the rotor temperature rises to 160 degrees Celsius, the shape memory alloy 16 wire begins to contract. The contracted shape memory alloy 16 wire drives the blade to rotate around the elastic hinge structure through the fixed seat 17 and the connecting seat 15, thereby reducing the blade angle.

[0049] The change in the included angle between blade 14 can be calculated using the lever principle. Assuming the shrinkage or elongation of the shape memory alloy 16 wire is ΔL, and the distance from the blade root to the connection point is R, the change in the included angle Δθ between blade 14 and rotor yoke 6 can be calculated using the following formula:

[0050]

[0051] For example, if the shape memory alloy wire shrinks by 5mm, and the distance from the root of blade 14 to the connection point is 10cm, then:

[0052] ≈2.86 degrees

[0053] Through a passive adjustment mechanism using 16-wire shape memory alloy, the blade angle (-14) automatically adjusts according to rotor temperature, optimizing airflow, improving heat dissipation efficiency, and reducing motor operating temperature. This eliminates the need for an external power supply and complex mechanical transmission devices, reducing system complexity and maintenance costs. The entire adjustment mechanism is simple, reliable, and easy to install and maintain. The mechanical structure design considers strength and stability, with limit devices and angle markings ensuring long-term stable operation. The choice of 16-wire shape memory alloy material ensures reliability and durability under various operating conditions.

[0054] When the blades rotate at high speed, the smaller angle reduces the angle of attack between the blades and the airflow, allowing the airflow to flow more smoothly along the blade surface. This design reduces airflow separation and vortex generation on the blades, thereby improving airflow efficiency and dynamic performance. The smaller angle also means that the blades have a smaller frontal area when rotating at high speed, but the airflow velocity per unit area increases, thus generating a stronger airflow. This design helps to more effectively remove the heat generated by the motor, improving heat dissipation efficiency.

[0055] Example 2, refer to Figures 1-11 This is the second embodiment of the present invention, which differs from the first embodiment in that: a base 39 is fixedly connected to the surface of the rotor yoke 6, located on the side of the sensing base 7. A groove 40 is formed on the surface of the base 39, and a support seat 22 is fixedly connected to the surface of the groove 40 and to the bottom of the rotor yoke 6. The base 39 provides additional support and stability, and the groove 40 on its surface accommodates subsequent components. The support seat 22 is fixedly connected to the surface of the rotor yoke 6 to support and fix other related components, ensuring the overall structure is robust and operates reliably.

[0056] Compared to Embodiment 1, the surface of the support base 22 is further provided with two fixed blocks 23 in symmetrical positions, a bridging plate 25 rotatably connected between the two fixed blocks 23, a rotating shaft 26 fixedly connected to the end of the bridging plate 25 away from the fixed blocks 23, and an elastic strip 24 fixedly connected between the bridging plate 25 and the support base 22. The support base 22, the fixed blocks 23, the bridging plate 25, and the elastic strip 24 together form an elastic hinge structure.

[0057] Furthermore, blades 27 are fixedly connected to the surface of the rotating shaft 26. Connecting ropes 31, arranged in a linear array on the outer surface of blades 27, are fixedly connected to the outer surface of blades 27. A centrifugal block 32 is fixedly connected to the end of the connecting ropes 31 away from blades 27. Two mounting seats 28 are fixedly connected to the inner surface of blades 27 near the rotating shaft 26. A support shaft 29 is rotatably connected between the two mounting seats 28. An adjusting plate 30 is fixedly connected to the surface of the support shaft 29. Utilizing the centrifugal force generated by the rotor rotation and the pressure difference generated by airflow, a passive adjusting mechanism is used to change the angle of the cooling blades. This passive adjusting mechanism consists of blades 27, adjusting plate 30, and centrifugal block 32. It can automatically adjust the blade angle according to the rotor speed to optimize airflow and heat dissipation.

[0058] During operation, when the rotor yoke 6 rotates, the centrifugal block 32 generates an outward centrifugal force. The magnitude of the centrifugal force is directly proportional to the rotational speed of the rotor yoke 6; the higher the rotational speed, the greater the centrifugal force. This centrifugal force is transmitted to the blade 27 via an elastic hinge, reducing the included angle of the blade 27. For example, when the rotor yoke 6 rotates at 1000 r / min, the centrifugal force is relatively small, and the included angle of the blade 27 remains at 30 degrees. When the rotational speed increases to 2000 r / min, the centrifugal force increases, and the included angle of the blade 27 decreases to 20 degrees. The rotating blade 27 cuts through the air, generating airflow. The regulating vane 30 generates a torque under the action of the airflow. This torque is in the same direction as the centrifugal force, further reducing the included angle of the blade 27. For example, when the rotor yoke 6 rotates at a lower speed, the torque generated by the regulating vane 30 is smaller, and the included angle of the blade 27 is mainly adjusted by the centrifugal force. When the rotor yoke 6 rotates at a higher speed, the torque generated by the regulating vane 30 increases, further reducing the included angle of the blade 27 and optimizing the airflow. The elastic hinge has a restoring force, which allows blade 27 to return to its initial angle when the centrifugal force and hydrodynamic torque disappear. This ensures that blade 27 maintains a stable initial position at low speeds or when the machine is stopped.

[0059] By adjusting the blade angle, the motor can achieve optimal heat dissipation at different speeds. At high speeds, reducing the blade angle increases airflow, improves heat dissipation efficiency, and prevents the motor from overheating. At low speeds, a larger blade angle ensures sufficient airflow and maintains the motor's normal temperature.

[0060] The remaining structure is the same as that in Example 1.

[0061] Example 3, referring to Figures 1-7This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that: the center point of the fixed ring 5 is rotatably connected to a drive shaft 34, the surface of which is fixedly connected to the surface of the rotor yoke 6, the surface of the drive shaft 34 is rotatably connected to a stator 36, the stator 36 is disposed between the two rotor yokes 6, and the self-cooling component is disposed on the outer wall surface of the stator 36.

[0062] Compared to Embodiment 2, the self-cooling component further includes a plurality of liquid storage strips 4 fixedly connected to the cover 2 and arranged in a circular pattern on the surface of the cover 2, a liquid delivery pipe 38 fixedly connected to the surface of the liquid storage strips 4, and a condenser pipe 37 fixedly connected to the liquid delivery pipe 38, the condenser pipe 37 being wound around the surface of the stator 36.

[0063] The control system receives the position signal of the shift plate 20 transmitted wirelessly by the position sensor 19, processes it, and triggers the regulation mechanism of the self-cooling component. Specifically, the control system commands the liquid delivery pipe 38 connected to the liquid storage bar 4 to sequentially transfer the pre-stored cooling liquid in the liquid storage bar 4 to the liquid delivery pipe 38 using principles such as gravity, and then guides it to the condenser pipe 37 tightly wound on the surface of the stator 36. The liquid in the condenser pipe 37 evaporates or convects under the action of the heat generated by the stator 36, effectively absorbing and carrying away the heat inside the stator 36 and the motor, realizing an automatic and efficient cooling process.

[0064] The remaining structure is the same as that in Example 2.

[0065] Example 3, referring to Figures 1-7 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that: a drive shaft is rotatably connected to the center point of the fixed ring and its surface is fixedly connected to the surface of the rotor yoke. A stator is rotatably connected to the surface of the drive shaft. The stator is disposed between the two rotor yokes. A self-cooling component is disposed on the outer wall surface of the stator.

[0066] Compared to Embodiment 2, the self-cooling component further includes a plurality of liquid storage strips fixedly connected to the cover and arranged in a circular pattern on the surface of the cover, a liquid delivery pipe fixedly connected to the surface of the liquid storage strips, and a condenser pipe fixedly connected to the liquid delivery pipe, wherein the condenser pipe is wound around the surface of the stator.

[0067] The control system receives the position signal of the shifted plate wirelessly transmitted by the position sensor, processes it, and triggers the regulation mechanism of the self-cooling component. Specifically, the control system instructs the liquid delivery pipe connected to the liquid reservoir to start, using principles such as gravity to sequentially transfer the pre-stored cooling liquid in the liquid reservoir to the delivery pipe, and then guide it to the condenser tube tightly wound on the surface of the stator. The liquid in the condenser tube evaporates or convects under the action of the heat generated by the stator, effectively absorbing and carrying away the heat inside the stator and motor, realizing an automatic and efficient cooling process.
