[0023] Example: See also Figures 1 to 6 The three-dimensional flux disk motor with axial-radial mixed flux in the preferred embodiment of the present invention can not only ensure that the motor has higher power and higher torque density, making the motor suitable for high-power working requirements, but also can achieve lightweighting of the entire motor while reducing the structural size of the motor as much as possible.

[0024] Specifically, if Figures 1 to 6 As shown in the preferred embodiment of the present application, the three-dimensional flux disk motor includes a stator mechanism and a rotor mechanism. The stator mechanism includes a support member and a plurality of convex stators. The support member serves as the mounting base for the convex stators. During actual use of the motor, the position of the support member is relatively fixed. Furthermore, a plurality of mounting locations are evenly arranged along the circumference on the outer wall surface of the support member for securing the convex stators.

[0025] Furthermore, each convex stator includes an iron core 1, an axial winding 3, and a radial winding 4. The sidewall of each iron core 1 is fixedly mounted on the mounting position of the support member. Simultaneously, each iron core 1 is provided with axial stator teeth along the central axis of the support member, and axial windings 3 are provided on the axial positioning teeth, thereby enabling the axial windings 3 to form an induced magnetic field along the axial direction when energized. Furthermore, radial stator teeth 2 are provided on the sidewall of each iron core 1 facing away from the mounting position, and radial windings 4 are provided on the radial stator teeth 2, thereby enabling the radial windings 4 to form an induced magnetic field along the radial direction when energized.

[0026] Further preferably, the rotor mechanism includes an axial rotor and a radial rotor. The axial rotor includes an axial turntable 7 and a plurality of first permanent magnets 8. The axial turntable 7 is spaced apart at one end of the iron core 1 where the axial stator teeth are provided. Furthermore, the first permanent magnets 8 are evenly spaced circumferentially around the central axis on the end surface of the axial turntable 7 facing the axial stator teeth, thereby forming an axial magnetic field above the axial stator teeth. When the radial winding 4 is energized, the magnetic field generated by the energized axial winding 3 and the first permanent magnets 8 can drive the axial rotor mechanism to rotate relative to the stator mechanism, thereby converting electrical energy into mechanical energy.

[0027] Furthermore, the radial rotor includes a radial turntable 10 and a plurality of second permanent magnets 11. The radial turntable 10 is coaxially sleeved on the outside of the support member. At the same time, the second permanent magnets 11 are evenly spaced along the circumferential direction on the inner wall surface of the radial turntable 10, and there is a gap between each second permanent magnet 11 and the radial stator teeth 2.

[0028] In actual use, the three-dimensional flux disk motor in this application uses a three-dimensional flux permanent magnet array to achieve higher torque density by adding the number of pole pairs under the same volume, and the structural form of the axial flux motor enables it to utilize space more effectively and reduce the axial length, thereby further improving the torque density.

[0029] Specifically, the torque formula of an axial flux motor is usually expressed as:

[0030] K is the axial flux motor constant, p is the number of pole pairs, is the air gap flux density (T), is the armature current density (A / m), is the effective rotor area (m²) The torque formula of the radial flux motor can be simplified as:

[0031] is the motor constant of the radial flux motor, is the air gap flux density (T), is the armature current density (A / m), L is the effective length of the motor, and r is the rotor radius The volume V of the axial flux motor can be approximately expressed as:

[0032] Therefore, the torque density T d It can be expressed as:

[0033] Because A r It can be expressed as πR 2 ,therefore

[0034] The volume 𝑉 of the radial flux motor can be approximately expressed as:

[0035] Therefore, the torque density T d It can be expressed as:

[0036] Comparing the two formulas, the axial flux motor can achieve higher torque density within the same volume by increasing the number of pole pairs p. In addition, the structural design of the axial flux motor allows for more efficient use of space and reduces the axial length L, further improving torque density.

[0037] Furthermore, axial flux motors improve torque and power density by increasing the number of pole pairs. The disc-shaped structure allows for more pole pairs to be arranged. Axial flux motors can be designed to be shorter, thus improving torque and power density.

[0038] Specifically, the output power P can be expressed as

[0039] in is the angular velocity of the motor, and its relationship with the speed n (rpm) is

[0040] Axial flux motor

[0041] After simplification:

[0042] Radial flux motor:

[0043] It can be seen from the formula that the axial flux motor can achieve higher power density in the same volume by increasing the number of pole pairs p and increasing the speed n.

[0045] During actual use, the magnetic flux starts from the first permanent magnet 8 located at both ends of the axis, passes through the gap between the first permanent magnet 8 and the iron core 1, and enters the axial ends of the iron core 1. After passing through the iron core 1, the magnetic flux flows out from the radial stator teeth 2. After passing through the radial air gap, the outflowing magnetic flux flows radially into the second permanent magnet 11. Then, the magnetic flux flows out through the second permanent magnet 11 and enters the radial turntable 10 (radial outer rotor yoke) tangentially. Then, it flows out from the radial turntable 10 and passes through the radial air gap. It enters the adjacent iron core 1 from the radial stator teeth 2 of the adjacent convex stator, and then returns to the first permanent magnet 8 axially through the axial gap, thereby forming a loop and realizing axial-radial mixed magnetic flux.

[0052] During actual use, the spatial position of the iron core 1 relative to the stator mounting plate 5 is first adjusted so that the first bolt hole 6 on the iron core 1 can correspond to the position of the second bolt hole 13 on the stator mounting plate 5. On this basis, a bolt is inserted into the second bolt hole 13 on the side of the stator mounting plate 5 away from the iron core 1, and then the bolt is screwed in until the bolt enters the first bolt hole 6 on the iron core 1 and the second bolt hole 13 on the stator mounting plate 5 at the same time, thereby realizing a detachable connection between the iron core 1 and the stator mounting plate 5.

[0053] In more detail, in a preferred embodiment of the present application, two first bolt holes 6 are provided at axial intervals on the inner ring wall surface of the iron core 1.

Further preferably, ten first permanent magnets 8 are disposed on the axial turntable 7, and accordingly, the stator mechanism is provided with twelve iron cores 1.

[0057] Further preferably, in the preferred embodiment of the present application, a plurality of second permanent magnets 11 are arranged evenly spaced along the circumferential direction on the inner ring wall surface of the radial turntable 10 facing the iron core 1. Preferably, the second permanent magnets 11 are also a magnetic steel structure in the shape of a fan ring, and the second permanent magnets 11 extend in the axial direction.

[0059] Further preferably, in the preferred embodiment of the present application, a plurality of heat dissipation blades arranged along a ring are provided on the axial turntable 7, thereby forming an axial heat dissipation ring 9 on the axial turntable 7. Preferably, the axial heat dissipation ring 9 is arranged in the area between the outer ring of the axial turntable 7 and the outer ring wall of the first permanent magnet 8, so as to ensure that the axial turntable 7 can not only provide a stable installation base for the first permanent magnet 8, but also form a corresponding heat dissipation area on the axial turntable 7, thereby enabling the axial rotor to simultaneously dissipate heat for the stator mechanism during rotation.

[0060] In more detail, in a preferred embodiment of the present application, heat dissipation rings are provided on both axial turntables 7, thereby forming a heat dissipation duct arranged along the axial direction on the rotor structure.

[0061] Furthermore, in a preferred embodiment of the present application, a plurality of heat dissipation blades arranged in a ring are provided on the radial turntable 10, thereby forming a radial heat dissipation ring 12 on the radial turntable 10. Preferably, the radial rotor is provided with heat dissipation rings on both axial sides of the second permanent magnet 11, thereby ensuring that the radial rotor can provide stable support for the second permanent magnet 11 while also forming a corresponding heat dissipation area on the radial turntable 10, so that during the rotation of the radial rotor, the radial heat dissipation ring 12 arranged along the circumferential direction can be used to introduce the airflow into the receiving groove along the circumferential direction, thereby forming a circulation in the space, and then promoting the mixing and convection of the air, and further improving the heat dissipation efficiency.

[0062] Further preferably, in the preferred embodiment of the present application, each heat dissipation blade is arranged obliquely within the heat dissipation ring. Simultaneously, each heat dissipation blade is arranged parallel and spaced apart, thereby ensuring that the rotation of the heat dissipation blades can generate cooling air flowing along the axial direction, thereby effectively achieving efficient heat dissipation of the stator.

[0063] The three-dimensional magnetic flux disk motor with axial-radial mixed magnetic flux in the present invention has a compact structure, high torque density and power density, and stable operation. By adopting a flattened stator mechanism and rotor mechanism, the magnetic flux is distributed along the axial direction of the motor to ensure that the motor can have a shorter magnetic path, thereby significantly improving the efficiency of the motor while reducing magnetic loss. At the same time, since the motor as a whole is a flattened structure, the motor structure is more compact and the arm length of the rotor mechanism can be increased, thereby significantly improving the motor output torque, and then greatly improving the power and torque density of the motor. At the same time, by adding radial stator teeth 2, radial windings 4 and second permanent magnets 11 to the outside of the iron core 1, the torque and power density of the motor are significantly improved. In addition, combined with the heat dissipation structure provided on the radial turntable 10 and the axial turntable 7, the rotor mechanism can provide flowing heat dissipation air for the stator during rotation, ensuring that the motor can continue to operate in a stable temperature environment, and has good promotion prospects and reference value.
