Referring to Figure 1, the electrical structure 100 according to the first embodiment includes a first stacked structure 110, an insulating plate 130, and a second stacked structure 150 as a basic structure, and other openings ( 200), an incision 300, and cooling channels 400. Hereinafter, each configuration of the electrical structure 100 will be described in detail.

First, the first stacked structure 110 and the second stacked structure 150 commonly refer to a structure including one or more metal plates 111, and as shown in FIG. 1, thin plate-shaped metallic members are sequentially stacked. It is understood to include all structures. Each metal plate 111 constituting the first stacked structure 110 and the second stacked structure 150 may be formed of any metallic material as long as it has electrical conductivity. The metal plate 111 may be, for example, a member made of copper, aluminum, zinc, brass, nickel, iron, tin, gold, and silver, and preferably copper. When the metal plate is made of copper, there is an effect that can solve the price and supply and demand problems of rare earth metals. Meanwhile, the metal plates 111 constituting each stacked structure may be made of the same metal material or different metal materials from each other. For example, assuming that the first stacked structure 110 is composed of three metal plates, all three metal plates may be made of the same metal material, or at least one of the three metal plates May be of a different metal material. In addition, the metal plates constituting the first stacked structure 110 and the second stacked structure 150 may also be the same or different, for example, all of the metal plates forming the first stacked structure 110 are copper. When the members are made of, the metal plates constituting the second stacked structure 150 may also be members made of copper or members made of gold instead of copper.

Meanwhile, the first stacked structure 110 or the second stacked structure 150 may be composed of at least one or more metal plates 111, and preferably, 4 to 10 metal plates may be sequentially stacked. have. At this time, each metal plate may have a thickness of 0.3mm to 1.5mm, more preferably 0.5mm to 1mm. However, this is only an example, and it should be understood that the number of stacked metal plates and the thickness of individual metal plates may vary depending on the purpose and operation of the electric device to be implemented.

In addition, current flows through the first stacked structure 110 and the second stacked structure 150, for example, when current is applied to a metal plate disposed on the uppermost layer of the first stacked structure 110. The current may pass through all the metal plates of the first stacked structure 110 to reach the metal plate disposed on the lowest layer of the first stacked structure 110, and further, the lowermost layer of the first stacked structure 110 It is conducted to the metal plate disposed on the uppermost layer of the second stacked structure 150 connected to (soldered) to flow through all the metal plates of the second stacked structure 150. As mentioned, the first stacked structure 110 and the second stacked structure 150 are connected so that electricity can flow therebetween, and the type of the structure connecting them will not be limited as long as the conduction of current is possible.

On the other hand, referring to Figure 3, the shape of the metal plate 111 may be a shape similar to a fan shape when viewed in a plan view, and more precisely, it may be implemented in a shape similar to the side surface of the development of the truncated cone. The shape of the plate will be described in detail with reference to FIG. 3. The metal plate is formed from two straight lines (l1, l2) extending from an imaginary center point (O) and forming an arbitrary center angle (θ) from the center point (O). It may be designed in a shape surrounded by a first arc h1 having an arbitrary first radius r, and a second arc h2 having an arbitrary second radius R from the center point O. At this time, the size of the central angle θ may be designed so as not to exceed 180 degrees, and preferably within a range of 20 degrees to 90 degrees.

Meanwhile, the shape of the metal plate is not limited to the shape shown in FIG. 1 or 3, and may be designed in various shapes, which will be described with reference to FIGS. 4 and 5.

4 and 5 show different shapes of the metal plate.

Referring first to FIG. 4, the metal plate has two line segments (l3, l4) extending from two points (P1, P2) spaced apart from each other by the same distance from the virtual center point (O); at this time, the two line segments are straight lines. When extended to a right angle), the first curve (h3) having the first curvature connected to one end of the two segments, and the second curve having the second curvature (h4) connecting the other ends of the two segments ), In particular, the metal plate of FIG. 4 may be designed such that angles (θ3, θ4) between the tangential line and each line segment in the vicinity of the first curve and the line segment are less than 90 degrees. have.

On the other hand, Figure 5 shows another metal plate shape. Referring to FIG. 5, the metal plate has two line segments l5 and 16 extending from two points P3 and P4 spaced apart from each other by the same distance from the virtual center point O; When extended, it forms a right angle), a third curve (h5) having two curvature segments connected to each other but having a third curvature, and a fourth curve (h6) connecting the other ends of the two segments but having a fourth curvature It can be designed in a shape surrounded by, in particular, the metal plate of FIG. 5 can be designed such that the angle between the tangent line and each line segment in the vicinity of the contact point of the third curve and the line segment is 90 degrees or more.

Although various design shapes of the metal plate have been described above, it is understood that the metal plate is not limited to the above-described embodiment and that the shape of the metal plate may be variously designed according to the purpose of the electric device 1000. .

Next, referring back to FIG. 1, the insulating plate 130 refers to a plate-shaped member disposed between the first stacked structure 110 and the second stacked structure 150, and is particularly made of a material that is not electrically conductive. It is characterized by. If the material constituting the insulating plate 130 is a material having high electrical resistance, there will be no limitation, for example, rubber, polystyrene, acrylic resin, glass, ebonite, mica, bakelite, porcelain, etc. It may be selected as a material constituting the.

The insulating plate 130 may have a thickness of 0.1mm to 0.3mm, and preferably may have a thickness of 0.15mm. However, it should be understood that, like the metal plate 111, the thickness of the insulating plate 130 may also vary depending on the purpose and operation of the electrical device 1000 to be implemented.

Regarding the shape of the insulating plate 130, when referring to FIG. 1, the shape of the insulating plate 130 is formed with the metal plates 111 constituting the first stacked structure 110 and the second stacked structure 150. It can be designed in a similar or identical shape.

Meanwhile, the first stacked structure 110, the second stacked structure 150, and the insulating plate 130 described above commonly include an opening 200, an incision 300, and a cooling channel 400. It can be done, but it will be described in detail below for each configuration.

First, the opening 200 refers to a hole formed such that a portion of the inner area of each metal plate 111 and the insulating plate 130 penetrates each plate. As shown in FIGS. 1 and 3, the shape of each opening 200 may be similar to or identical to the overall shape of each plate, and preferably maintain the same shape as the outer circumferential surface of each plate, but the same shape with only a small scale. Can be

The opening 200 formed in each plate is meaningful in that it provides a path through which current flows, especially in a metal plate. Specifically, the current passing through the metal plate due to the presence of the opening 200 is along the plate surface between the outermost side of the plate and the opening 200, that is, along the plate surface existing outside the opening 200. It can flow in one direction.

In addition, the opening 200 formed in each plate may be utilized for the purpose of inserting the teeth of the core in designing a motor to be described later.

Next, the incision 300 refers to a groove extending from the inner side of the opening 200 formed in each plate to the outer circumference (outer side) of the plate. The incision 300 may also be seen as a configuration that contributes to providing a path for a current flowing along the metal plate surface. For example, when the one end and the other end of the metal plate are distinguished based on the incision 300, the current is It can flow from one end of the metal plate to the other end of the metal plate along the aforementioned path.

Meanwhile, in FIGS. 1 and 3, the incision 300 is formed in a direction toward an arbitrary center point that can be set based on an arc of the plate, but the direction in which the incision 300 is formed is I understand that it is not limited. For reference, when referring to the metal plates of FIGS. 4 and 5 described above, it can be seen that the incision is formed toward the outside from the opening in the corresponding metal plate.

On the other hand, in FIG. 1, only the shape in which the incision 300 formed in the metal plate and the incision 300 formed in the insulating plate 130 are formed in the same direction and the same width is also shown in the embodiment of FIG. 1. I understand that it is not limited. For example, considering that the first stacked structure 110 and the second stacked structure 150 should be connected by mutual soldering or the like, the incision 300 formed in the insulating plate 130 is attached to the upper and lower metal plates. It can be formed with a width of a larger value compared to, or by being formed in a different direction from the incision 300 of the upper and lower metal plate, the electrical connection between the first stacked structure 110 and the second stacked structure 150 in the vertical direction You can also make it happen.

Next, the cooling channels 400, that is, a plurality of cooling channels 400 penetrating the upper and lower surfaces of each plate but having a smaller area than the opening 200 when viewed in a plan view are formed on each plate. You can. The cooling channels 400 are formed for the purpose of cooling heat that may occur when an electric current flows in the electrical structure 100, and are a passage through which any fluid, for example, coolant, can pass. FIG. 2 shows a passage formed by the cooling channels 400 when the metal plate and the insulating plate 130 are stacked, and shows a cross section of A-A 'of FIG. 1. Referring to FIG. 2, the cooling channels 400 form a so-called cooling path from the upper surface of the first stacked structure 110 to the lower surface of the second stacked structure 150 through the insulating plate 130. Able to know.

Meanwhile, in FIGS. 1 to 3, although the cooling channels 400 are shown as circular when viewed in a plan view, it is understood that the shapes of the cooling channels 400 are not limited thereto and can be designed in various shapes. do.

For example, FIG. 6 shows another shape of the cooling channel formed in the plate. According to FIG. 6, the cooling channel may be formed in a rectangular shape having an arbitrary curved length φ and a width d, and the curved length φ may be different depending on a distance from an imaginary center point.

As described above, the first stacked structure 110, the second stacked structure 150, and the insulating plate 130 constituting the electrical structure 100 according to the first embodiment have been described.

Hereinafter, the electrical structure 100 according to the second embodiment will be described with reference to FIGS. 7 to 9.

The electrical structure 100 according to the second embodiment basically includes the same components as the electrical structure 100 in the first embodiment, but only when the metal plates and the insulating plate 130 are laminated, they are misaligned. There are structural differences in that respect. In this detailed description, for convenience, each plate is displaced, or a displaced structure is referred to as a skew, and the following description will be continued.

7 and 9, the first stacked structure 110, the second stacked structure 150, and the insulating plate 130 are spaced apart from each other by a predetermined distance when viewed in plan view. Can be confirmed. More precisely, the (n + 1) layer plate may be disposed on the n-layer plate in the plan view. At this time, the n-layer plate and the (n + 1) layer plate are spaced apart at regular intervals to form a skew structure. Will be achieved.

The reason why the plates are stacked in a skew structure as described above is to increase the cooling efficiency of the electrical structure 100, because a slanted cooling furnace made of a skew structure is more advantageous for cooling than a one-shaped cooling furnace. to be. 8 shows a cooling path of the electrical structure 100 according to the second embodiment, whereby the cooling channels 400 formed on the respective plates are the cooling channels 400 formed on the upper and lower plates. And are arranged to share at least some channel area, resulting in a diagonal cooling furnace as shown in FIG. 8. Previously, in the electrical structure 100 according to the first embodiment, as shown in FIG. 2, a one-shaped cooling path was formed, whereas in the electrical structure 100 according to the second embodiment, diagonal lines were arranged by disposing each plate in a skew structure. It forms a cooling furnace in the form. When comparing the cooling furnaces of FIGS. 2 and 8, the cooling furnace in FIG. 8 basically has a wider surface that comes into contact with the passage of the fluid, and thus an increase in cooling efficiency can be expected, and furthermore, a diagonal cooling furnace When the furnace fluid passes, an increase in cooling efficiency can be expected due to the chaotic advection effect.

On the other hand, the shape of the cooling furnace may be implemented in a form including at least two diagonal lines such as> and <as well as a diagonal line. That is, at the time of stacking the plates, at least two diagonal lines are included by skewing a certain distance to the left from the n-th to (n + 3) layers, and skewing a certain distance to the right to the (n + 4)-(n + 7) layers. Cooling furnace shape can be realized.

First, the electrical device 1000 of FIG. 10 is an electrical device 1000 implemented by arranging a plurality of electrical structures 100 previously described in FIG. 1. Referring to FIG. 10, it can be seen that four electrical structures 100 according to the first embodiment are arranged in a circle to constitute one electrical device 1000. The electrical device 1000 according to the present invention may preferably be implemented by combining a plurality of electrical structures 100, but the electrical device 1000 does not necessarily include a plurality of electrical structures 100, one It is understood that the electrical structure 100 of itself can also function as one electrical device 1000. However, in this detailed description, a plurality of electrical structures 100 will be described based on an example of configuring one electrical device 1000 to help understanding of the present invention.

Referring back to FIG. 10, the electrical device 1000 according to the third embodiment is made of a total of four electrical structures 100, the number of electrical structures 100 included in the electrical device 1000 is the above It may vary depending on the shape of the metal plate and the insulating plate 130 constituting the electrical structure 100. Each of the electrical structures 100 of the electric device 1000 disclosed in FIG. 10 shows a case in which the size of the center angle θ mentioned in FIG. 3 is 90 degrees, for example, the respective metal plates and the insulating plate 130 If the center angle (θ) of the size is 60 degrees, a total of six electrical structures 100 will be required to implement one circular electric device 1000.

와 같은 형상으로 이루어질 수 있다. On the other hand, in the electrical device 1000 according to the third embodiment, a circular opening may be formed at the center when viewed in a plan view, and the shape of the opening formed in this way also depends on the shapes of the plates constituting each electrical structure 100. Will follow. For example, in the case where the electrical structure 100 is composed of plates of the shape described in FIG. 4 or 5, the opening formed in the center of the electrical device 1000 is

The electrical device 1000 of FIG. 11 has a skew structure as described above. It is implemented by arranging a plurality of electrical structures 100 in combination.

The electrical devices 1000 described above are implemented by a combination of a plurality of electrical structures 100, and the overall shape of the electrical device 1000 is the shape of each electrical structure 100 constituting it, and more precisely, the electrical structure. It is understood that it can be designed differently according to the shape of the plates forming the (100). In addition, although the electrical devices 1000 of FIGS. 10 and 11 illustrate an embodiment in which the electrical structures 100 are arranged in a circular shape, the arrangement of the electrical structures 100 is not necessarily formed in a circular shape. It is understood that the device 1000 may be arranged in various shapes according to needs, such as a driving purpose of the apparatus 1000, an industrial field to be utilized, and an installation location.

At this time, the electrical device 1000 and the second core 4000 are combined to function as a rotor in the motor. The second core 4000 may be referred to as a rotor core in other terms, and the second core 4000 is characterized in that a plurality of second teeth are formed. The second protrusions are formed to face the first protrusions of the first core 3000, which will be described later. In addition, the second protrusions are respectively coupled to the opening 200 formed in the electrical structure 100 of the electrical device 1000, and the second protrusions of the second core 4000 are provided on the outer peripheral surface of the electrical device ( Each of the electrical structures 100 of 1000) may be wrapped, and strong electromagnetic is induced by the current flowing through the electrical device 1000, thereby axially rotating with respect to the stator, which will be described later.
