New description: [New technical field] This creation is an improved structure of the axial air gap permanent magnet generator stator, which can reduce the production cost and improve the efficiency of the generator. At present, the axial air gap generator Wind power generation is mostly used, because wind turbines do not have an endless source of energy input like engine generators. Therefore, the generators used by wind turbines are more demanding in terms of efficiency, and the design of coreless coils is often used to remove starting torque. The ability of a wind turbine to operate at low wind speeds. According to the special requirements of wind turbines, this new patent changes the circular coils used in conventional generators. Instead of using flat coils to minimize the required volume of the coil stator, it can reduce the rotor magnetic lining. Increase the power generation efficiency of the generator's flat full contact without the space of the stator winding and operation _ heat dissipation is good, it is also quite helpful for the turn. This creation is more clever, and the wiring of the circuit board makes the flat wire connection simple. It can also speed up the production of the "module_architecture" to greatly reduce the manufacturing cost. M397104 99. v [Prior Art] The design and manufacturing techniques of vertical axis generators are mostly from traditional motors. The winding method using traditional circular coils requires the generator to have a large air gap space, especially when used. Wind power generation adopts a coreless design, and excessive magnet spacing will greatly reduce power generation efficiency. Figure i, Figure 2 is a cutaway view and side view of the axial air gap generator, 41 is the disc of the stator coil, 33 and 34 are the upper and lower rotor discs, and 3 32 are the magnets touching the rotor disc It is obvious that the stator plate is completely f彡 and the distance of the magnetic ray is loud.

[New content] ~ This work proposes to use flat copper wire _ to increase the efficiency of the stator space for the concept of generator winding _ concept and to design the modular coil structure, which can improve the power generation efficiency of the generator and is modularized. The manufacturing method reduces production costs. The flat copper wire is not a newly developed coil specification. Many motors also adopt a winding method for flat coils. However, the use of circular coils is still popular because the flat coils are not wound like circular coils. Flexible, according to the user's (four) any silk green line _ winding, but the flat is not easy to bend in the direction of the long side, the flat coil wiring and the coil module's access line method, need to do special design considerations to be effective _ The advantage of flat lines. This design uses a circuit board-like structure to fix the flat coil into a module type and complete the flat wire connection at the same time as shown in FIG. 5 and FIG. 6. 4 is a circuit board in which the coil modules 61 and 62 are fixed flat coils. The stator center wiring circuit board fixes the coil module, and the circuit wiring on the circuit board is used to complete the wiring of each coil at the same time, and the generator stator wiring can be completed quickly and easily. The coil module does not use a conventional circular coil instead of a flat coil to increase the efficiency of the stator space.

從表1可以清楚比較出當圓形線圈使用線徑越大時扁平線所 擁有優勢越大，原因為此時圓形線圈彼此間的孔隙越大，在此 三種圓形線徑的比較中扁平線的截面積甚至都較圓形線圈 大，但所排列出來的繞線结果都可以比圓形線圈厚度更小，截 面積大表示相同電流於銅線中流動時的銅損熱量較小。比較設 計的圖c-3項，甚至可以比圓形線圈纏繞結果少3mm的厚度 空間，所以根據此比較的結果可得知扁平線配合此模組化的設 計能有效的減小氣隙距離，同時也可以減少銅損的產生。 此線圈模組有兩大特色. 1. 利用電路板做為支撐結構同時完成扁平線的接線，又可中 心定子接線電路板方便連接，達成快速模組化製程。 2. 使用扁平狀線圈’增加定子空間的使醇以降低氣隙所需 空間，提高發電機效率。 【實施方式】 本創作巧妙的以電路板做為線圈模組的支撐結構同時完 成爲平線圈的接線如圖8啦，其中以兩塊板6卜62 = 合三組扁平線圈5卜52、53，電路板上電路走㈣11、612、° 621、622需配合爲平線圈串聯而設計安排，三組線圈繞線的 8 砂.㈣ 起始與結束位置也必須相互配合，再利用 導電的三根短銅柱 541、542以及543連結_板與爲平線。以此設計為例，假 設電流由下電職62的621電路進人線關_ a方線流入 銅柱54卜經過b進入53扁平線圈，延線_時針走向從c 路徑接回62電路板上的622走線，再經由d路徑傳至5幻銅 柱e路徑導入52線圈，透過f路徑連至61電路板上的612走 線將電流傳至542銅柱，則可延h路徑將電流傳至51線圈， 最後由i路徑將電流傳至61電路板上的611路徑，如此傳遞 過程將電流從621導入611導出完成整個線圈模組的傳遞。每 一個線圈模組再由圖6中63的定子接線電路板做三線不同線 圈模組的串接，完成完整發電機的線路。 【圖式簡單說明】 圖1轴向氣隙發電機剖開圖 圖2轴向氣隙發電機剖面圖 圖3圓形線圈示意圖與斷面圖 圖4圓形線圈示意圖 圖5扁平線圈模組 圖6線圈模組與定子接合示意圖 M397104It can be clearly seen from Table 1 that the greater the advantage of the flat wire when the circular coil is used, the larger the porosity of the circular coils is, and the flatness of the three circular diameters is flat. The cross-sectional area of the wire is even larger than that of the circular coil, but the wound wire results can be smaller than the thickness of the circular coil. The large cross-sectional area indicates that the copper current loss when the same current flows in the copper wire is small. Comparing the design of Figure c-3, it can even be 3mm less than the circular coil winding result, so according to the results of this comparison, it can be seen that the flat wire with this modular design can effectively reduce the air gap distance, It can also reduce the occurrence of copper loss. The coil module has two major features. 1. Using the circuit board as a supporting structure to complete the wiring of the flat wire at the same time, the center stator wiring circuit board can be easily connected to achieve a rapid modular process. 2. Use a flat coil to increase the space required to reduce the air gap in the stator space and improve generator efficiency. [Embodiment] This creation cleverly uses the circuit board as the support structure of the coil module and simultaneously completes the wiring of the flat coil as shown in Fig. 8. Among them, two boards 6 b 62 = three sets of flat coils 5 52, 53 The circuit on the circuit board (4) 11, 612, ° 621, 622 need to be matched with the flat coil series design, the three sets of coil winding 8 sand. (4) The start and end positions must also match each other, and then use the conductive three short The copper posts 541, 542, and 543 are connected to the plate and are flat. Taking this design as an example, it is assumed that the current is switched from the 621 circuit of the lower electric power 62 to the line _ a square line flows into the copper column 54 and passes through b into the 53 flat coil, and the extension _ hour hand goes back from the c path to the 62 circuit board. The 622 trace is transmitted to the 52 coil via the d path to the 5 magic copper e path, and the current is transmitted to the 542 copper column through the f path to the 612 trace on the 61 circuit board, and the current can be extended by the h path. To 51 coils, the current is passed from the i path to the 611 path on the 61 board. This transfer process directs current from 621 to 611 to complete the transfer of the entire coil module. Each coil module is further connected by a three-wire different coil module from the stator wiring board of Fig. 6 to complete the complete generator circuit.
