The rotor disk 210 is sleeved on the outer periphery of the drive shaft and is fixedly connected to the drive shaft. The drive shaft has a second cavity 232 that extends axially through it.

The frame of the flying equipment can extend a support column through the second cavity 232 as a hook, which, together with a lifting rope, enables the lifting of items. Compared to drone lifting using ordinary motors, flying equipment using this flux motor can adopt a hollow mounting method, making its mounting point geometric center more concentrated, the overall force more balanced, and less prone to tilting during flight.

A rotor disk 210 is sleeved on the outer periphery of the transmission cylinder 220, making the rotor disk 210 and the transmission cylinder 220 coaxially arranged. The rotor disk 210 and the transmission cylinder 220 can be manufactured from the same piece of material to achieve a fixed connection between them. A first transmission part 221 is provided at one end of the transmission cylinder 220 along its axial direction.

[0032] Reference Figure 4 , Figure 6 and Figure 7As shown, the transmission cylinder 220 has an installation cavity, and the drive shaft 230 passes through the installation cavity. The outer diameter of the drive shaft 230 is adapted to the inner diameter of the installation cavity, so that the outer circumferential surface of the drive shaft 230 can fit against the inner circumferential surface of the installation cavity. The outer circumferential surface of the drive shaft 230 is provided with a second transmission part 231, which is engaged with the first transmission part 221 to fix the drive shaft 230 and the transmission cylinder 220 circumferentially.

[0033] Reference Figure 4 , Figure 7 and Figure 8 As shown, the rotor disk 210 is used to match the stator assembly 300 to generate a rotational driving force. The rotor disk 210 is sleeved on the outer periphery of the transmission cylinder 220 and fixedly connected to the transmission cylinder 220. Through the mutual engagement and limiting of the first transmission part 221 and the second transmission part 231, the drive shaft 230 and the transmission cylinder 220 can be circumferentially fixed, so that the drive shaft 230 and the rotor assembly 200 can rotate synchronously to realize the transmission connection between the rotor disk 210 and the drive shaft 230. Compared with other transmission structures, it can simplify the structure of the rotor assembly 200 and make the transmission between the rotor disk 210 and the drive shaft 230 more stable and reliable.

[0034] The transmission shaft includes a transmission cylinder 220 and a drive shaft 230. The rotor disk 210 is sleeved on the outer periphery of the transmission cylinder 220 and fixedly connected to it. The transmission cylinder 220 and the drive shaft 230 achieve circumferential fixation and stable transmission through the engagement of the first transmission part 221 and the second transmission part 231. This flux motor, through the separate design of the transmission cylinder 220 and the drive shaft 230, can reduce the manufacturing difficulty and cost of the rotor assembly 200.

[0035] Compared to motor structures that use screws to assemble the rotor, the flux motor provided in this embodiment of the invention can assemble the transmission cylinder 220 and the drive shaft 230 simply by fitting the first transmission part 221 and the second transmission part 231 together. The transmission cylinder 220 and the drive shaft 230 are circumferentially fixed and stably transmitted, resulting in a simple assembly structure and a convenient assembly process.

[0036] Specifically, the drive shaft 230 includes a first shaft and a second shaft arranged coaxially. A second transmission part 231 is disposed on the outer peripheral surface of the first shaft. The outer diameter of the first shaft is larger than the outer diameter of the second shaft. The second shaft extends through the housing 100. The first shaft and the second shaft are arranged in a stepped manner and connected to each other. A stepped surface is formed between the first shaft and the second shaft of the drive shaft 230. The first shaft and the second shaft together enclose a second cavity 232 that extends axially. When this flux motor is applied to a flight device, the flight device can be a heavy-duty drone. The propeller of the flight device can be connected to the second shaft and abut against the stepped surface to achieve positioning.

[0037] Reference Figure 4 , Figure 7 and Figure 8 As shown, it can be understood that the first transmission part 221 consists of a plurality of inserts 2211 arranged circumferentially, and the second transmission part 231 consists of a plurality of slots 2311 arranged circumferentially, with each insert 2211 corresponding to each slot 2311.

[0038] Reference Figure 4 , Figure 7 and Figure 8 As shown, specifically, the shapes of the insert 2211 and the groove 2311 are adapted to each other so that after the groove 2311 and the insert 2211 are engaged, the top of the insert 2211 fits against the bottom wall of the groove 2311, and the two sides of the insert 2211 fit against the two sides inside the groove 2311, thereby realizing the mutual engagement and positioning of the insert 2211 and the groove 2311.

[0039] Reference Figure 4 , Figure 7 and Figure 8 As shown, when the rotor disk 210 and the transmission cylinder 220 rotate, the drive shaft 230 can be driven to rotate synchronously through the mutual contact between the insert 2211 and the slot 2311, so as to realize rotation drive.

[0040] Reference Figure 4 , Figure 7 and Figure 8 As shown, it should be noted that the flux motor can limit the displacement of the rotor assembly 200 and the drive shaft 230 along their axial direction by limiting the housing 100, thereby ensuring that the insert 2211 and the slot 2311 remain engaged during operation and preventing the insert 2211 from coming out of the slot 2311.

[0041] It should be understood that in some other embodiments, the second transmission part 231 is a plurality of inserts 2211 arranged circumferentially, while the first transmission part 221 is a plurality of slots 2311 arranged circumferentially, with each slot 2311 corresponding to and fitting into each insert 2211.

Specifically, the following description is given with both ends of the transmission cylinder 220 extending in the vertical direction and both ends of the drive shaft 230 extending in the vertical direction as an example.

[0043] Reference Figure 2 , Figure 4 and Figure 5 As shown, the second transmission part 231 is located between the end and the middle of the drive shaft 230, and the groove 2311 of the second transmission part 231 is oriented towards the middle of the drive shaft 230. The first transmission part 221 is located between the end and the middle of the transmission cylinder 220. During assembly, the user can adjust the relative positions of the first transmission part 221 and the second transmission part 231 so that the first transmission part 221 and the second transmission part 231 are positioned opposite each other, and each insert 2211 is fitted into each groove 2311 in a one-to-one correspondence. This allows the transmission cylinder 220 to be fitted near the middle region of the drive shaft 230, making the transmission between the transmission cylinder 220 and the drive shaft 230 more stable.

[0044] Reference Figure 4 , Figure 5 and Figure 6 As shown, it is understood that, in order to avoid damage caused by collision between the insert 2211 and the slot 2311 during transmission or assembly, the end of the insert 2211 away from the rotor disk 210 has two apex corners. Correspondingly, the two bottom corners of the slot 2311 away from the insert 2211 are respectively provided with notches 2312, and each notch 2312 is arranged opposite to each apex corner.

Correspondingly, the stator assembly 300 of the flux motor is provided with a first magnet 3112. When a changing current is passed through the coil, the rotor assembly 200 can rotate relative to the stator assembly 300. The first magnet 3112 can be a permanent magnet.

[0048] It should be understood that in some other embodiments, the rotor disk 210 is provided with a plurality of first mounting slots 211 arranged circumferentially thereon, the first mounting slots 211 being configured to accommodate magnets. The flux motor may be a permanent magnet synchronous motor / brushless DC motor.

[0049] Permanent magnets, such as neodymium iron boron, are installed on the rotor disk 210. Correspondingly, the stator assembly 300 of the flux motor can be wound with coils. When a changing current is passed through it, a rotating magnetic field is generated, thereby driving the rotor disk 210 to rotate.

[0050] Reference Figure 4 , Figure 7 and Figure 8 As shown, it can be understood that in this embodiment, the first mounting groove 211 is provided through both ends of the rotor disk 210. The flux motor includes two stator assemblies 300, and the rotor disk 210 of the rotor assembly 200 is disposed between the two stator assemblies 300. That is, the two stator assemblies 300 can work together on the rotor assembly 200 to realize the rotational drive of the rotor assembly 200. Without significantly increasing the size and weight of the motor, it can effectively improve the power and torque output, and enhance the fault tolerance and system reliability, realizing redundant drive.

[0051] It should be understood that in some other embodiments, one or two end faces of the rotor disk 210 are provided with a plurality of first mounting slots 211, and the flux motor can use multiple sets of stator assemblies 300 to drive the rotor assembly 200 to rotate, which can effectively improve the rotational stability of the rotor assembly 200.

[0052] Reference Figure 2 , Figure 9 and Figure 10 As shown, it can be understood that in this embodiment, the stator assembly 300 includes a stator body, which is arranged in a ring shape. The two ends facing away from each other of the stator body are respectively provided with a driving part 310 and an assembly part 320. The assembly part 320 includes a plurality of snap-fit ​​blocks 321 arranged circumferentially at intervals. The snap-fit ​​blocks 321 are configured to be positioned and assembled with the housing 100. The driving part 310 is configured to drive the rotor assembly 200 to rotate.

[0053] Reference Figure 2 , Figure 9 and Figure 10 As shown, the stator assembly 300 is arranged in a ring shape, that is, the stator assembly 300 is hollow, and the central space of the stator assembly 300 can accommodate the drive shaft 230 of the rotor assembly 200 to form a rotary drive. The stator assembly 300 can be accommodated in the receiving cavity 140 of the housing 100.

[0054] Reference Figure 2 , Figure 9 and Figure 10As shown, the stator assembly 300 has a drive section 310 and an assembly section 320 at its two opposite ends. The assembly section 320 includes a plurality of snap-fit ​​blocks 321 arranged circumferentially at intervals. The assembly section 320 is configured to abut and connect with the housing 100.

[0055] Specifically, the inner circumferential surface of the housing 100 is provided with a plurality of circumferentially spaced positioning grooves 150, all of which communicate with the receiving cavity 140. A plurality of snap-fit ​​blocks 321 can respectively engage with the plurality of positioning grooves 150 on the housing 100, thereby achieving positioning of the stator body and the housing 100. Specifically, the snap-fit ​​blocks 321 can be threadedly connected to the housing 100 by screws, thereby achieving a fixed connection between the assembly part 320 and the housing 100, simplifying the assembly structure of the stator assembly 300, rotor assembly 200, and housing 100.

[0056] Reference Figure 2 , Figure 9 and Figure 10 As shown, a drive unit 310 is provided at one end of the stator body facing away from the assembly part 320. The drive unit 310 is configured to generate a rotating magnetic field. This stator assembly 300 can cooperate with the rotor assembly 200 to reduce the difficulty of assembling with the rotor assembly 200. The rotating magnetic field drives the rotor assembly 200 to rotate, thereby realizing the function of rotation drive. Specifically, the stator body can be made of silicon steel.

[0057] Reference Figure 2 , Figure 9 and Figure 10 As shown, it can be understood that, specifically, the assembly part 320 also includes a plurality of snap-fit ​​slots 322 arranged circumferentially, and the number of snap-fit ​​slots 322 is greater than the number of snap-fit ​​blocks 321.

[0058] Reference Figure 2 , Figure 9 and Figure 10 As shown, each snap-fit ​​block 321 can be connected to a suitable snap-fit ​​slot 322, thereby enabling the stator assembly 300 to be adapted for assembly and use with more types of housings 100. For example, the user can select an appropriate number of snap-fit ​​blocks 321 according to the requirements of the selected housing 100, and connect each snap-fit ​​block 321 to the appropriate snap-fit ​​slot 322. Then, through the engagement and connection of multiple snap-fit ​​blocks 321 with the positioning grooves 150 of the housing 100, the stator body is fixedly connected to the housing 100. The snap-fit ​​blocks 321 can be welded to the snap-fit ​​slots 322 as a whole.

[0059] Reference Figure 2 , Figure 9 and Figure 10As shown, specifically, the empty slot 322 can be used as a weight reduction slot, which can reduce the overall weight of the stator assembly 300, thereby reducing the weight of the flux motor and also reducing the manufacturing cost of the stator assembly 300.

This can effectively simplify the connection structure between the snap-fit ​​block 321 and the snap-fit ​​groove 322, and reduce the connection difficulty between the snap-fit ​​block 321 and the snap-fit ​​groove 322. That is, the snap-fit ​​block 321 can be directly inserted into the snap-fit ​​groove 322, thereby realizing the connection between the snap-fit ​​block 321 and the snap-fit ​​groove 322.

[0061] Reference Figure 2 , Figure 9 and Figure 10 As shown, the snap-fit ​​groove 322 extends radially through the stator assembly 300 and is open at one end away from the drive section 310, which can increase the surface area of ​​the snap-fit ​​groove 322, thereby improving the heat exchange efficiency between the stator assembly 300 and the external environment, that is, improving the heat dissipation efficiency of the stator assembly 300.

[0062] Reference Figure 2 , Figure 9 and Figure 10 As shown, it can be understood that the end of the snap-fit ​​block 321 is provided with a connection hole 3211. That is, when the user fits multiple snap-fit ​​blocks 321 into multiple positioning grooves 150 of the housing 100, the user can fix the connection to the housing 100 by passing screws through the connection hole 3211, thereby realizing the fixed connection between the stator assembly 300 and the housing 100.

[0063] Reference Figure 2 , Figure 9 and Figure 10 As shown, it can be understood that the diameter of the snap-fit ​​slot 322 gradually increases in the direction of the drive unit 310, the width of the snap-fit ​​block 321 gradually increases in the direction of the drive unit 310, and one end of the snap-fit ​​block 321 is configured to be able to be inserted into the snap-fit ​​slot 322, and the other end is configured to protrude out of the snap-fit ​​slot 322.

[0064] Reference Figure 2 , Figure 9 and Figure 10As shown, specifically, the snap-fit ​​groove 322 is a dovetail groove, and the matching snap-fit ​​block 321 is a dovetail block. The snap-fit ​​block 321 can be inserted into the snap-fit ​​groove 322, and through the mutual limiting of the snap-fit ​​groove 322 and the snap-fit ​​block 321, the snap-fit ​​block 321 and the snap-fit ​​groove 322 are restricted from separating along the axial direction of the stator body, so as to achieve the initial positioning of the snap-fit ​​block 321 and the snap-fit ​​groove 322.

[0065] Reference Figure 2 , Figure 9 and Figure 10 As shown, it can be understood that the drive unit 310 includes a plurality of drive units 311 arranged circumferentially. The plurality of drive units 311 can work together to drive the rotor assembly 200 so that the rotor assembly 200 can rotate smoothly.

[0066] Reference Figure 2 , Figure 9 and Figure 10 As shown, the stator assembly 300 decomposes the drive section 310 into multiple standardized drive units 311, which helps reduce the difficulty of manufacturing and facilitates automated winding of the drive units 311, thereby greatly simplifying the assembly process and improving efficiency. The modular design of the drive units 311 isolates the magnetic circuits of each phase winding, effectively preventing the spread of phase-to-phase short-circuit faults. Even if a drive unit 311 fails, the motor can usually continue to operate, which significantly improves the fault tolerance and reliability of the flux motor.

[0067] Reference Figure 2 , Figure 9 and Figure 10 As shown, specifically, the drive unit 311 includes a connecting block 3111 and a first magnet 3112. The connecting block 3111 can be part of the stator body, making the positions of the multiple connecting blocks 3111 relatively stable. The first magnet 3112 is a permanent magnet.

[0068] Reference Figure 2 , Figure 9 and Figure 10 As shown, the stator assembly 300, through a specific layout and the connection between the connecting block 3111 and the first magnet 3112, can "collect" and guide magnetic field lines to the working area, forming a "magnetic focusing" effect in the central area. This enhances the strength of the main magnetic field, thereby directly improving the torque density and operating efficiency of the flux motor.

[0069] Reference Figure 2 , Figure 9 and Figure 10 As shown, the independent drive unit 311 creates space for optimized armature winding design. For example, a more efficient "single-turn connected winding" can be used, which reduces AC losses and increases the motor power density of the flux motor.

[0070] Reference Figure 2 , Figure 9 and Figure 10 As shown, it can be understood that in the drive unit 311, an insulating layer 3113 is provided between the connecting block 3111 and the first magnet 3112.

[0071] Reference Figure 2 , Figure 9 and Figure 10 As shown, during motor operation, alternating magnetic fields induce eddy currents in these conductive components. The flux motor provided in this embodiment of the invention, with its circumferential insulating layer 3113, physically cuts off the path of the eddy currents, forcing them to be confined to a very small range. This effectively suppresses eddy current losses and directly improves the motor's operating efficiency.

[0072] Reference Figure 2 , Figure 9 and Figure 10 As shown, it can be understood that the connecting block 3111 has a limiting piece 3114 at one end facing away from the assembly part 320. The limiting piece 3114 protrudes from the edge of the connecting block 3111, and the edge of the limiting piece 3114 can abut against the first magnet 3112 to prevent the first magnet 3112 from coming out of the connecting block 3111.

[0073] Reference Figure 2 , Figure 9 and Figure 10 As shown, the limiting piece 3114 can restrict the first magnet 3112 and the insulating layer 3113 from axially dislodging from the stator body, which can effectively improve the connection stability between the connecting block 3111 and the first magnet 3112 and the insulating layer 3113, thereby improving the durability and safety of the stator assembly 300.

[0074] Reference Figure 2 , Figure 9 and Figure 10 As shown, it can be understood that the width of the connecting block 3111 gradually increases from the inside to the outside, and an installation spacing 330 is constructed between two adjacent drive units 311, and the cross-sectional dimensions of the installation spacing 330 are consistent in its extension direction.

[0075] Reference Figure 2 , Figure 9 and Figure 10 As shown, the cross-sectional dimensions of the installation spacing 330 remain consistent in its extension direction, which makes the stator assembly 300 perform more stably, has more balanced heat dissipation, and is more efficient in manufacturing and assembly.

That is, the first heat dissipation section 111 and the second heat dissipation section 121 are located at opposite ends of the housing 100.

[0078] Reference Figure 1 , Figure 11 and Figure 12 As shown, for the flux motor, the stator assembly 300 and rotor assembly 200, and other built-in components are all housed within the housing 100. The first housing 110 and the second housing 120 together protect the built-in components. The two opposite end faces of the housing 100 are respectively provided with a first heat dissipation part 111 and a second heat dissipation part 121, which can effectively improve the heat dissipation efficiency for the heat-generating built-in components and effectively reduce the risk of overheating of the flux motor.

[0079] Reference Figure 1 , Figure 11 and Figure 12 As shown, the first housing 110 has a through-hole first cavity in its middle, and the second housing 120 has a through-hole second cavity in its middle. When the first housing 110 and the second housing 120 are connected, the first cavity and the second cavity are opposite to each other and interconnected to form a first cavity 130. The through-hole direction of the first cavity and the second cavity is consistent with the axis of the flux motor.

[0080] Reference Figure 1 , Figure 2 and Figure 11 As shown, it can be understood that the first housing 110 and the second housing 120 together enclose and form a receiving cavity 140 surrounding the first cavity 130. For a flux motor, components such as the stator assembly 300 and the rotor assembly 200 can be housed within the receiving cavity 140. While achieving rotational drive, the second cavity 232 allows hoisting components and wires to pass through, thereby improving applicability to hoisting and wiring scenarios.

The first heat dissipation part 111 has multiple first heat dissipation slots 1111 arranged in a circumferential direction, which can be used in various flight directions. This allows the airflow in each flight direction to flow quickly through the first heat dissipation slots 1111 opposite to it, thereby improving the heat exchange efficiency between the first heat dissipation part 111 and the external air, and thus improving the heat dissipation effect of the housing 100.

[0083] Reference Figure 1 , Figure 11 and Figure 12 As shown, it can be understood that the first heat dissipation part 111 also includes a plurality of first heat dissipation fins 1112. Each first heat dissipation groove 1111 is provided with a plurality of first heat dissipation fins 1112 arranged in a row. The edges of the first heat dissipation fins 1112 are connected to the bottom wall and the peripheral wall of the first heat dissipation groove 1111. Two adjacent first heat dissipation fins 1112 and the first heat dissipation groove 1111 together form a first gas flow channel 1113. The first gas flow channel 1113 opens toward the side of the first housing 110 and toward the direction of the first housing 110 away from the second housing 120.

[0084] Reference Figure 1 , Figure 11 and Figure 12 As shown, the first heat dissipation unit 111 has multiple first heat dissipation fins 1112 in each of the first heat dissipation slots 1111. The edges of the first heat dissipation fins 1112 are connected to the bottom wall and peripheral wall of the first heat dissipation slot 1111, and the multiple first heat dissipation fins 1112 are arranged at intervals. By setting multiple first heat dissipation fins 1112, the first heat dissipation unit 111 can effectively increase the heat dissipation area, thereby improving the heat dissipation efficiency with the external environment.

[0085] Reference Figure 1 , Figure 11 and Figure 12 As shown, specifically, two adjacent first heat dissipation fins 1112 and the first heat dissipation groove 1111 together form a first gas flow channel 1113, so that the orientation of the first gas flow channel 1113 of each first heat dissipation groove 1111 is different, which can achieve heat transfer in multiple directions and improve the heat dissipation efficiency of the first heat dissipation part 111.

[0086] Reference Figure 1 , Figure 11 and Figure 12 As shown, it can be understood that the second heat dissipation part 121 includes a plurality of second heat dissipation slots 1211 arranged circumferentially, the second heat dissipation slots 1211 penetrating the side of the second housing 120 and the end face of the second housing 120 facing away from the first housing 110.

[0087] Reference Figure 1 , Figure 11 and Figure 12 As shown, the multiple second heat dissipation slots 1211 arranged circumferentially in the second heat dissipation part 121 can increase the contact area with the external airflow, thereby improving the heat exchange efficiency between the first heat dissipation part 111 and the external environment, and thus improving the heat dissipation effect of the housing 100.

[0088] Reference Figure 1 , Figure 11 and Figure 12 As shown, the second heat dissipation section 121 also includes a plurality of second heat dissipation fins 1212. Each second heat dissipation groove 1211 has a plurality of second heat dissipation fins 1212 arranged at intervals from the inside to the outside. The edges of the second heat dissipation fins 1212 are connected to the bottom wall and the peripheral wall of the second heat dissipation groove 1211.

Specifically, the second gas flow channel 1213 is arc-shaped.

[0089] Reference Figure 1 , Figure 11 and Figure 12 As shown, multiple second heat dissipation fins 1212 arranged from the inside out can quickly disperse the heat originally concentrated at the end of the second housing 120 to the surrounding area. That is, the second heat dissipation part 121 can improve the efficiency of heat transfer from the inside to the outside through the cooperation of the second heat dissipation fins 1212 and the second heat dissipation grooves 1211, thereby improving the heat dissipation performance of the housing 100.
