[0027] See also Figures 1 to 5 It is shown as Example 1 of the present utility model. It should be explained in advance that the relevant numbers and appearances mentioned in the corresponding drawings of this embodiment are only used to specifically illustrate the implementation method of the present utility model to facilitate understanding of the content of the present utility model, rather than to limit the protection scope of the present utility model.

[0028] This embodiment discloses a motor structure 100 that avoids using silicon steel sheets as magnetic force conductors, thereby reducing the size of the motor structure 100. Furthermore, the motor structure 100 of this embodiment can cooperate with the high switching speed of the control circuit to achieve the purpose of low inductance, high power density and small size.

[0029] It should be noted that, in order to facilitate understanding of this embodiment, the attached drawings only show a partial structure of the motor structure 100, so as to clearly show the structure and connection relationship of each component of the motor structure 100, but the present invention is not limited to the attached drawings. The following will introduce each component of the motor structure 100 and its connection relationship.

[0030] like Figure 1 As shown, the motor structure 100 of this embodiment includes a shell 1, a stator assembly 2 accommodated in the shell 1, a rotor assembly 3 accommodated in the stator assembly 2 and spaced apart from the stator assembly 2, and a control circuit 4 electrically coupled to the stator assembly 2 and the rotor assembly 3.

[0031] like Figure 1 and Figure 2 As shown, in this embodiment, the housing 1 is generally a hollow cylinder. That is, a housing space (not shown) is provided inside the housing 1 to accommodate the stator assembly 2 and the rotor assembly 3, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the housing 1 can also be square in shape, but the housing space of the housing 1 is cylindrical to accommodate the stator assembly 2 and the rotor assembly 3.

[0032] In this embodiment, the housing 1 has an upper housing (not shown) and a lower housing (not shown). The housing 1 can utilize the upper housing and the lower housing so that the stator assembly 2, the rotor assembly 3 and the control circuit 4 can be accommodated in the housing 1, but the present invention is not limited thereto.

[0033] like Figure 3 and Figure 4 As shown, in this embodiment, the stator assembly 2 is generally cylindrical in shape, and the cross-sectional shape of the stator assembly 2 is generally circular, so that the stator assembly 2 can be assembled in the housing 1, but the utility model is not limited thereto. The stator assembly 2 includes a stator core 21 and at least one coil circuit board 22 on which the stator core 21 is disposed.

[0034] In this embodiment, the material of the stator core 21 is a ferrite core. Since the ferrite core material has advantages such as high magnetic permeability, easy acquisition, and low cost compared to silicon steel sheet material, using the ferrite core as the material of the stator core 21 can reduce the inductance of the motor structure 100, reduce the number of winding turns required for the motor structure 100, and reduce the overall size of the motor structure 100 and reduce the cost.

[0035] like Figure 3 and Figure 4 As shown, the stator core 21 is roughly cylindrical in shape and can be effectively accommodated in the housing 1. The stator core 21 has a core body 211 and a plurality of magnetic conductive columns 212 arranged on the core body 211. The core body 211 is roughly cylindrical in shape. A through hole 2111 is provided in the center of the core body 211. The through hole 2111 is circular in shape, and the through hole 2111 and the core body 211 are concentric circles. The through hole 2111 is for accommodating the rotor assembly 3. The core body 211 has a first side surface 2112 and a second side surface 2113 located on opposite sides.

[0036] The shape of the first side surface 2112 is generally circular, but the utility model is not limited thereto. The first side surface 2112 is adjacent to the at least one coil circuit board 22, and a plurality of magnetic conductive pillars 212 are disposed on the first side surface 2112 of the magnetic core body 211. The plurality of magnetic conductive pillars 212 surround the through hole 2111 and stand upright on the magnetic core body 211.

[0037] It should be noted that the number of the plurality of magnetic conductive pillars 212 is an even number in this embodiment. That is, the number of the plurality of magnetic conductive pillars 212 in this embodiment is 12, and the plurality of magnetic conductive pillars 212 are located on the opposite side of the through hole 2111, so as to generate windings of different polarities so as to rotate the rotor assembly 3, but the utility model is not limited thereto. For example, in other embodiments not shown in the utility model, the number of the plurality of magnetic conductive pillars 212 can be adjusted to an odd number or an even number according to the winding method in the coil circuit board 22.

[0038] In this embodiment, the plurality of magnetic conductive pillars 212 are evenly dispersed in the through hole 2111. That is, the plurality of magnetic conductive pillars 212 are arranged in a circle around the through hole 2111, and the distances between adjacent magnetic conductive pillars 212 in the plurality of magnetic conductive pillars 212 are the same, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the distances between adjacent magnetic conductive pillars 212 in the plurality of magnetic conductive pillars 212 can be adjusted and varied according to actual design requirements.

[0039] In addition, in this embodiment, the plurality of magnetic conductive pillars 212 and the magnetic core body 211 are integrally formed, and the material of the plurality of magnetic conductive pillars 212 is the same as the iron powder core material of the magnetic core body 211, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the material of the plurality of magnetic conductive pillars 212 is different from the material of the magnetic core body 211, and the plurality of magnetic conductive pillars 212 are connected to the magnetic core body 211 in a fixed manner (e.g., welding, fusion, or screw connection), or are adjusted and changed according to actual design requirements.

[0040] In this embodiment, the connection line segment 311 includes a first connection line portion 3111 and a second connection line portion 3112 electrically connected to the first connection line portion 3111. The first connection line portion 3111 is buried in the gold-plated film 4. In other words, the second connection line portion 3112 is covered by the gold-plated film 4. The second connection line portion 3112 is electrically connected to the inner circuit 32 and is exposed to the insulating outer layer 2 and the gold-plated film 4.

[0041] like Figure 3 and Figure 4As shown, the at least one coil circuit board 22 has a plurality of printed circuits 221 corresponding to the number of the plurality of magnetic conductive pillars 212, and the plurality of printed circuits 221 are respectively wound around the plurality of magnetic conductive pillars 212. In this embodiment, the number of the at least one coil circuit board 22 is one, but the utility model is not limited thereto. The coil circuit board 22 is a multi-layer circuit board, and the coil circuit board 22 is provided with a plurality of fixed through holes 222 corresponding to the number of the plurality of magnetic conductive pillars 212, and the plurality of fixed through holes 222 are respectively provided for the plurality of magnetic conductive pillars 212 to pass through.

[0042] It should be noted that the plurality of fixed through holes 222 correspond to the positions of the plurality of magnetic conductive pillars 212 and are arranged in a circle around the through hole 2111, and the distances between adjacent fixed through holes 222 in the plurality of fixed through holes 222 are the same, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the distances between adjacent fixed through holes 222 in the plurality of fixed through holes 222 can be adjusted according to actual design requirements.

[0043] Furthermore, the plurality of printed circuits 221 on the coil circuit board 22 are respectively wound around the plurality of fixed through-holes 222. In this embodiment, each printed circuit 221 is wound around each fixed through-hole 222 on the coil circuit board 22, which is equivalent to being wound around each magnetic conductive column 212. In other words, each printed circuit 221 is wound around each magnetic conductive column 212 to generate a winding. The plurality of printed circuits 221 on the coil circuit board 22 are wound around the plurality of magnetic conductive columns 212 to generate a plurality of windings, and the rotor assembly 3 can rotate through the plurality of windings.

[0044] It should be noted that, in this embodiment, the multiple printed circuits 221 on the coil circuit board 22 are used to replace the existing coils and are wound around the multiple magnetic conductive columns 212, thereby generating multiple windings that are different from the existing windings generated by silicon steel sheets, so that the stator assembly 2 of this embodiment is much smaller in size than the existing stator assembly.

[0045] It is worth noting that, in this embodiment, in order to enable the multiple windings and the rotor assembly 3 to generate magnetic induction and rotate, the arrangement of the multiple printed circuits 221 on the coil circuit board 22 of this embodiment is important. The following is an explanation of the multiple printed circuits 221 on the coil circuit board 22.

[0046] like Figure 5 As shown, it should be noted that, in order to facilitate understanding of the present embodiment, each of the printed circuits 221 on the coil circuit board 22 is wound around each of the magnetic conductive columns 212. Figure 3 The single printed circuit 221 in the coil circuit board 22 (ie, Figure 1 The single printed circuit 221 in the V portion is shown for illustration.

[0047] The coil circuit board 22 of this embodiment is a multi-layer circuit board, and each layer of the circuit board is provided with a plurality of printed circuits 221. For the convenience of description, the coil circuit board 22 of this embodiment is described as a three-layer circuit board, but the utility model is not limited thereto. The number of layers of the coil circuit board 22 can be changed and adjusted according to actual design requirements.

[0048] like Figure 5 As shown, the coil circuit board 22 of this embodiment includes a first layer coil circuit board 22a, a second layer coil circuit board 22b, and a third layer coil circuit board 22c. Each of the printed circuits 221 includes a plurality of annular conductive images 2211 in each layer of the coil circuit board 22, and the plurality of annular conductive images 2211 are arranged at intervals from each other. That is, the first layer coil circuit board 22a, the second layer coil circuit board 22b, and the third layer coil circuit board 22c respectively include a plurality of first annular conductive images 2211a, a plurality of second annular conductive images 2211b, and a plurality of third annular conductive images 2211c. The plurality of first annular conductive images 2211a, the plurality of second annular conductive images 2211b, and the plurality of third annular conductive images 2211c correspond to each other along a height direction.

[0049] Furthermore, the distance between any two adjacent first annular conductive images 2211a in the plurality of first annular conductive images 2211a is the same; the distance between any two adjacent second annular conductive images 2211b in the plurality of second annular conductive images 2211b is the same; and the distance between any two adjacent third annular conductive images 2211c in the third annular conductive images 2211c is the same. However, the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the distance between adjacent annular conductive images 2211 in the plurality of annular conductive images 2211 gradually increases in a direction away from the fixed through hole 222, or can be adjusted and changed according to actual design requirements.

[0050] In addition, the diameters of the plurality of annular conductive images 2211 of each layer of the coil circuit board 22 gradually increase in a direction away from the fixed through hole 222, and each of the annular conductive images 2211 of the adjacent coil circuit boards 22 are electrically coupled to each other through a conductive hole 23. Specifically, in this embodiment, the winding method of the printed circuit 221 on the coil circuit board 22 is that the first annular conductive image 2211a is first diffracted from the first circle of the first annular conductive image 2211a (such as the first circle of the first annular conductive image 2211a) closest to the magnetic pole 212. Figure 5 After that, the first annular conductive image 2211a of the first circle is electrically connected to the first circle of the second annular conductive image 2211b of the second coil circuit board 22b closest to the magnetic pole 212 through the conductive hole 23 (as shown in FIG. Figure 5 The first circle of the second annular conductive image 2211b is then electrically connected to the third coil circuit board 22c closest to the magnetic conductive column 212 through the conductive hole 23 to diffract the first circle of the third annular conductive image 2211c (as shown in FIG. Figure 5 As shown in C in FIG. 1 , the first circle of the printed circuit 221 wound around the magnetic pole 212 is completed.

[0051] After that, the third annular conductive image 2211c is wound around the outer periphery of the first circle of the third annular conductive image 2211c, and then the second and third circles of the annular conductive image 2211 are wound in the above-mentioned winding manner. As described above, the diameters of the plurality of annular conductive images 2211 of each layer of the coil circuit board 22 gradually increase in the direction away from the fixed through hole 222, and each of the annular conductive images 2211 of the adjacent coil circuit boards 22 are electrically coupled to each other through the conductive hole 23.

[0052] like Figure 5 As shown, this is only one of the winding methods of the printed circuit 221 of this embodiment, and the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the printed circuit 221 can first be provided with a plurality of the annular conductive images 2211 in each layer of the coil circuit board 22, and the plurality of the annular conductive images 2211 in any two adjacent coil circuit boards 22 are electrically connected to each other via one of the conducting holes 23.

[0053] Please refer to Figure 1 and Figure 2The rotor assembly 3 is located in the through hole 2111 of the stator assembly 2 and is spaced apart from the magnetic core body 211. The rotor assembly 3 can be rotated by the stator assembly 2. In detail, the rotor assembly 3 includes a rotor body 31 and a rotating shaft 32 disposed on the rotor body. The rotating shaft 32 is located at the axis of the rotor body 31. The rotating shaft 32 can be rotated by the rotor body 31.

[0054] In addition, if Figure 1 As shown, the control circuit 4 can control the stator assembly 2 and the rotor assembly 3 so that the rotor assembly 3 rotates in the through hole 2111 of the stator assembly 2. In detail, the control circuit 4 can be disposed on a control circuit board (not shown in the figure), and the control circuit 4 is electrically connected to the stator assembly 2 and the rotor assembly 3 through the control circuit board to control the stator assembly 2 and the rotor assembly 3 so that the rotor assembly 3 rotates in the through hole 2111 of the stator assembly 2, but the present invention is not limited thereto.

[0055] For example, in other embodiments not shown in the present invention, the control circuit 4 can be integrated on the coil circuit board 22, and the control circuit 4 is electrically connected to the stator assembly 2 and the rotor assembly 3 through the coil circuit board 22 to control the stator assembly 2 and the rotor assembly 3 so that the rotor assembly 3 rotates in the through hole 2111 of the stator assembly 2.

[0057] See also Figure 6 As shown, it is the second embodiment of the present utility model. Since this embodiment is similar to the above-mentioned first embodiment, the similarities between the two embodiments will not be repeated, and the differences between this embodiment and the above-mentioned first embodiment are roughly described as follows:

[0058] like Figure 6 As shown, the winding method of the plurality of printed circuits 221 in the coil circuit board 22 is different from Figures 1 to 5 In the embodiment of the present invention, the plurality of printed circuits 221 of the coil circuit board 22 are wound around two magnetic poles 212 as a group to generate a winding. That is to say, the plurality of printed circuits 221 of the present embodiment are wound around the periphery of the two magnetic poles 212 to generate a winding, but the present invention is not limited thereto. For example, in other embodiments of the present invention, the winding design of the plurality of printed circuits 221 of the coil circuit board 22 is different from the above-mentioned winding design. Figure 5 A in Figure 5In addition to the B winding method, there are also overlapping winding, concentric winding, or wave winding methods. This is based on the common knowledge of those skilled in the art.

Since this embodiment is similar to the above embodiment, the same parts of this embodiment as the above embodiment will not be described in detail, and the differences between this embodiment and the above embodiment 1 are roughly described as follows:

[0061] like Figure 7 As shown, the number of the at least one coil circuit board 22 corresponds to the number of the plurality of magnetic conductive pillars 212. In this embodiment, the number of the at least one coil circuit board 22 corresponds to the number of the plurality of magnetic conductive pillars 212 and is 12. Each of the coil circuit boards 22 is provided with a fixed through hole 222, and the fixed through hole 222 of each of the coil circuit boards 22 is sleeved on the plurality of magnetic conductive pillars 212, each of the coil circuit boards 22 has the printed circuit 221, and the printed circuit 221 on each of the coil circuit boards 22 is wound around the fixed through hole 222.
