The present invention relates to a multilayer planar winding winding structure and a manufacturing method thereof, in particular to a multilayer planar winding winding structure and a manufacturing method thereof in which a plurality of stacked planar winding sections are formed by surrounding wires from the inside to the outside.

Generally speaking, the operating principle of motors such as motors and generators is mainly to use the electromagnetic effect between the coil and the magnet to achieve the function of electromagnetism or magnetism to generate electricity, and then generate power or electricity, while common motors mainly use coils The combined structure of the stator and the rotor is formed with magnets; among them, whether it is stator winding or rotor winding, the existing practice is mostly to wind the wire from one end of the iron core to the other end, and then wind back to the original starting end, and so on. Type winding can form a multi-layer stack of coils. Although this kind of reciprocating winding coil can magnetize the iron core after being energized, it will actually cause part of the magnetic field generated by each layer of coil due to the reciprocating winding. Will offset each other, and thus cannot effectively use electricity.

In view of the fact that in the prior art, the existing coil windings are mostly reciprocating winding wires on the iron core, so that the iron core is magnetized when the coil windings are energized. However, the reciprocating winding of the wires will cause the winding of the adjacent two layers of coils. The spiral directions are different, so that part of the magnetic force cancels each other out. For this reason, the main purpose of the present invention is to provide a multilayer planar winding winding structure and a manufacturing method thereof, so that a plurality of planar winding sections stacked on each other can vary depending on the winding direction. The same and effective enhancement of the magnetic field.

The partition board has an outer edge and a socket hole and an inner edge, so that the inner edge is sleeved on the winding column and defines a first winding space and a second winding with the winding column In the space, the partition plate is further provided with an interlayer communication hole that penetrates the first winding space and the second winding space. The interlayer communication hole extends from the inner edge to the outer edge along an extension direction perpendicular to the axial direction, and the interlayer communication hole is The first winding space and the second winding space are connected.

The coil winding includes a first plane winding segment and a second plane winding segment. The first plane winding segment extends in the first winding space from a first winding start point adjacent to the inner edge along a winding direction from the inside to the outside around the winding column to the vicinity of the outer edge, and is connected between layers The hole reflexes toward the inner edge and extends to a first winding end point adjacent to the inner edge. The second plane winding segment extends in the second winding space from a second winding start point adjacent to the inner edge along the winding direction from the inside to the outside around the winding column to the vicinity of the outer edge, and the second winding start point is It is formed by bending and extending in the axial direction from the end point of the first winding.

In one of the auxiliary technical means derived from the above necessary technical means, the winding column includes a plurality of peripheral walls, which are connected to each other to form a hollow space, and one of the peripheral walls is provided with a wire hole connected to the hollow space , The coil winding is a wire extending from the hollow space through the wire perforation to the first winding start point.

In order to solve the problem of the prior art, another necessary technical means adopted by the present invention is to provide a manufacturing method of a multilayer planar winding winding structure, which includes the following steps: First, step (a) is to move a wire along a winding direction Surrounded from the inside to the outside to form a first plane winding section; then, step (b) is to stack a partition on the first plane winding section, and reflex the wire from one of the interlayer connecting holes of the partition to extend adjacent to One of the inner edges of the partition; next, step (c) is to extend the wire out of the interlayer communication hole, and make the wire surround the partition along the winding direction from the inside to the outside to form a second plane winding section, so as to make the first plane The winding section and the second plane winding section form a coil winding, thereby forming a multi-layer plane winding winding structure including a separator and a coil winding.

In a subsidiary technical means derived from the above-mentioned necessary technical means, before step (a), a step (a0) is further included. Step (a0) is to place a bobbin on a working platform, and step (a) Furthermore, the wire is wound around the winding column from the inside to the outside along the winding direction to form a first plane winding section. Preferably, in step (a), the wire is passed through a wire perforation of the bobbin, and the wire surrounds the bobbin from the inside to the outside along the winding direction.

As mentioned above, the multilayer planar winding winding structure of the present invention and its manufacturing method are mainly to surround the wire from the inside to the outside to form a planar winding segment, and use a partition to separate multiple planar winding segments to form multiple planar winding segments The stacked structure, and since each planar winding segment is formed by surrounding from the inside to the outside, the magnetic field generated by multiple planar winding segments can be effectively accumulated, and since the wire of each planar winding segment is surrounded from the inside to the outside Therefore, the length of the wire of each turn will increase from the inside to the outside, and the plane winding section will generate an inward concentrated magnetic field. When multiple plane winding sections are stacked, the magnetic field of the entire coil winding will be effectively concentrated. Generate a high-strength magnetic field.

The manufacturing method of a multilayer planar winding winding structure provided by this embodiment includes the following steps: first, as shown in the first figure, a winding column 1 is placed on a work platform 200; then, as shown in the first figure and As shown in the second figure, a wire 30 passes through a wire perforation 111 of the bobbin 1 and surrounds the bobbin 1 from the inside to the outside along a winding direction D3 to form a first plane winding section 31; then, As shown in the second and third figures, a partition 2a is passed through the bobbin 1 to be stacked on the first plane winding section 31, and the wire 30 is directed inward from one of the interlayer communication holes 24a of the partition 2a The edge 23a is folded back and extends to a first winding end point WE1 adjacent to the inner edge 23a.

Furthermore, as shown in the third and fourth figures, the wire 30 extends from the first winding end point WE1 along an axial direction D1 out of the interlayer communication hole 24a to a second winding starting point WS2, and then from the second winding point The starting point WS2 extends along a winding direction D3 from the inside to the outside around the winding column 1 to be adjacent to an outer edge 21a, thereby forming a second planar winding section 32, where the wire 30 starts from the first winding end point WE1 It extends along the axial direction D1 and then extends along the winding direction D3 perpendicular to the axial direction D1. Therefore, the second winding start point WS2 is actually slightly deviated from the position of the first winding end point WE1 above the axial direction D1. In addition, in other embodiments, the partition 2a may also be provided with a catch angle at the junction between the inner edge 23a and the interlayer communication hole 24a, so that the wire 30 extends from the interlayer communication hole 24a to the first winding terminal WE1. It can be more conveniently extended to the second winding start point WS2.

Finally, as shown in Figures 3 to 5, repeat the steps of stacking partitions 2a and surrounding formation of other plane winding segments (such as the first plane winding segment 31 or the second plane winding segment 32) to form a plurality of A multi-layer planar winding winding structure 100 in which a separator (including the separator 2a) and a plurality of planar winding segments (including the first planar winding segment 31 and the second planar winding segment 32) are stacked alternately, and the multilayer planar winding winding structure The detailed structure of 100 is detailed below.

Please continue to refer to the fifth and sixth figures. The sixth figure is a schematic diagram of the A-A section of the fifth figure. As shown in the first to sixth figures, a multilayer planar wire-wound winding structure 100 includes a bobbin 1, ten partitions 2a, 2b (only two are indicated in the figure), and a coil winding 3.

The bobbin 1 extends along an axial direction D1 and includes four peripheral walls 11, 12, 13 and 14. The peripheral walls 11 and 13 are spaced apart from each other and integrally connected to the two ends of the peripheral walls 12 and 14, thereby A hollow space 15 extending along the axial direction D1 is constructed; wherein, although in this embodiment, the winding column 1 is a square column composed of four peripheral walls 11, 12, 13, and 14, it is not limited to this, In other embodiments, it may also be a polygonal cylinder, but the number of sides is preferably an even number. In addition, in this embodiment, the peripheral wall 11 is further provided with a wire through hole 111, and the wire through hole 111 penetrates from the hollow space 15 to the outside of the peripheral wall 11.

The partition 2a has an outer edge 21a, a socket hole 22a is opened, and an inner edge 23a, so that the inner edge 23a is sleeved on the bobbin 1 and defines a first winding space with the bobbin 1 S1 and a second winding space S2, and the partition 2a is further provided with an interlayer communication hole 24a that penetrates the first winding space S1 and the second winding space S2. The interlayer communication hole 24a is formed from the inner edge 23a along a vertical line The extending direction D2 of the axial direction D1 extends to the outer edge 21a, and the interlayer communication hole 24a connects the first winding space S1 and the second winding space S2. Among them, the first winding space S1 and the second winding space S2 are mainly formed by sheathing the winding column 1 through the partition 2a to separate the circumference of the winding column 1.

The coil winding 3 includes a plurality of planar winding segments (only a first planar winding segment 31 and a second planar winding segment 32 are indicated in the figure for description). The first plane winding section 31 extends in the first winding space S1 from a first winding start point WS1 adjacent to the inner edge 23a in a winding direction D3 from the inside to the outside around the winding column 1 to adjacent to the outer edge At 21a, it reflexes and extends from the interlayer communication hole 24a toward the inner edge 23a to a first winding end point WE1 adjacent to the inner edge 23a. The second plane winding section 32 extends in the second winding space S2 from a second winding start point WS2 adjacent to the inner edge 23a along the winding direction D3 from the inside to the outside around the winding column 1 to the vicinity of the outer edge 21a, And the second winding start point WS2 is formed by bending and extending along the axial direction D1 from the first winding end point WE1. In addition, the structure of other plane winding segments (not shown in the figure) included in the coil winding 3 is equivalent to the first plane winding segment 31 and the second plane winding segment 32.

As mentioned above, in the third figure, since the winding column 1 is arranged on the working platform 200, the first winding space S1 is more restricted by the working platform 200, that is, the first winding space S1 is a partition 2a. The annular space enclosed by the winding column 1 and the working platform 200; on the contrary, in the third figure, the second winding space S2 is only separated by the partition 2a and the winding column 1 relative to The open space of the first winding space S1, however, as shown in the fifth and sixth figures, when the partition 2b is stacked on the second planar winding section 32, the second winding space S2 is also affected by the partition 2b. The limitation, that is, the second winding space S2 is an annular space surrounded by the partitions 2a and 2b and the winding post 1.

Please continue to refer to Figures 5 to 7. Figure 7 is a three-dimensional schematic diagram of the practical application of the multilayer planar winding winding structure of the present invention. As shown in the fifth to seventh figures, the multilayer flat-wound winding structure 100 of the present invention is a plurality of flat winding sections (including the first flat winding section 31 and the second flat winding section 32) through the coil winding 3 Staggered stacking with multiple partitions (including partitions 2a) forms a structure in which multiple planar winding segments are stacked on top of each other, and since each planar winding segment in this embodiment is formed around a square winding column 1, The multilayer planar winding winding structure 100 is divided into four linearly extending sections 100a, 100b, 100c, and 100d evenly, and since the wires 30 of each linearly extending section 100a, 100b, 100c, and 100d extend linearly, Therefore, each linear extension section 100a, 100b, 100c, and 100d will generate a significant magnetic field when energized. Therefore, the multilayer flat-wound winding structure 100 of the present invention can be used as a motor stator in practice. When a rotor 300 rotatably penetrates the hollow space 15 of the multilayer planar winding structure 100, the four magnetic fields generated by the linear extension sections 100a, 100b, 100c, and 100d will interact with the magnetic field of the magnet 302 of the rotor 300. The magnet 302 drives the rotating shaft 301 through the magnet 302 to rotate.

In summary, since the length of the wire 30 in each linear extension section 100a, 100b, 100c, and 100d increases from the inside to the outside, when the coil winding 3 is energized, each linear extension section 100a, 100b, The magnetic fields of 100c and 100d are both fan-shaped distributed magnetic fields that are concentrated from the outside to the inside, thereby increasing the intensity of the magnetic field inside the coil winding 3 relatively. In addition, since the coil winding 3 is composed of the same wire 30 to form four linear extension sections 100a, 100b, 100c and 100d, when the coil winding 3 is energized, the current will flow in the four linear extension sections 100a, 100b, 100c and The 100d wire 30 flows back and forth, so that the magnetic field generated by the coil winding 3 in the four linear extension sections 100a, 100b, 100c and 100d will also alternately cyclically change, which relatively increases the interaction of the magnetic field of the magnet 302 Ability means to accelerate the rotation speed of the rotor 300.

Please continue to refer to the fifth, sixth and eighth figures. The eighth figure is another three-dimensional schematic diagram of the practical application of the multilayer flat winding winding structure of the present invention. As shown in the fifth, sixth and eighth figures, in another practical application example of the present invention, eight multi-layer planar wound winding structures 100 (only one is indicated in the figure) can be evenly distributed and fixed On the stator frame 400, eight magnetic poles can be formed through the current control of the eight multilayer planar winding winding structure 100, and the rotor (not shown) arranged in the stator frame 400 is subjected to magnetic force. Rotate.

To sum up, compared with the existing coil windings, the wires are mostly reciprocally wound on the iron core. When the coil winding is energized, the magnetic force of the wire will be partially offset by the reciprocating winding of the wires; the present invention is mainly Enclose the wire from the inside to the outside to form a flat winding section, and then separate it with a partition, and then make the wire continue to surround the plane winding section from the inside to the outside, thereby forming a structure of multiple flat winding sections stacked, so by each The plane winding segment formed by the inner and outer surroundings can effectively accumulate the magnetic fields generated by multiple planar winding segments. Since the wire of each planar winding segment is surrounded from the inside to the outside, the length of the wire of each circle will change from the inside to the outside. The increase of the outer side relatively causes the plane winding section to generate an inwardly concentrated magnetic field. When multiple plane winding sections are stacked, the magnetic field of the entire coil winding will be effectively concentrated to generate a high-intensity magnetic field.

Through the detailed description of the preferred embodiments above, it is hoped that the characteristics and spirit of the present invention can be described more clearly, and the scope of the present invention is not limited by the preferred embodiments disclosed above. On the contrary, its purpose is to cover various changes and equivalent arrangements within the scope of the patent application for the present invention.
