Embodiment

[0063] In the coreless coil (continuous air-core α-turn) 1 of the first embodiment, the coil main body (a component composed of a conductive wire, an insulating coating, and a thermally adhesive coating) may be a so-called flat wire or a round wire. either. In addition, since the first embodiment is an example for explaining the present invention, the number of turns of the coil, the size, the thickness, and the ratio of the structure are not limited and interpreted by the drawings. Therefore, descriptions of well-known matters and detailed matters are omitted. In the present invention, design changes can be appropriately made within a range not exceeding the subject.

[0064] It should be stated, just in case, that the Figure 7 A second embodiment is shown in the figure. For the coreless coil (continuous air-core α-turn) 1A of the second embodiment, the single α-turn coil 10B may be in a substantially rectangular ring shape (for example, a substantially rectangular ring sh...

Abstract

In the coreless coil of the present invention, the plurality of α-turn coils is a coil formed by laminating a first coil layer each having a center opening and a second coil layer having the same shape and width as the first coil layer. Each peripheral part of the connection direction of a plurality of α-turn coils is respectively relative to the Z-axis of the central opening (herein, the Z-axis refers to, relative to the center of the two connection ends passing through the α-turn coil and the first coil layer and the second The X-axis of the lamination boundary surface of the two-coil layer passes through the centers of the two non-connecting ends of the α-turn coil and passes through the central axis of the lamination boundary surface in a manner perpendicular to the X-axis), and has a point-symmetric connection. In the stepped portion, a plurality of α-turn coils are connected in a ring shape so that the connecting stepped portions overlap each other and are connected to each other. An object of the present invention is to improve the coupling force of the plurality of α-turn coils.

Description

technical field [0001] The present invention relates to a coreless coil for a small electric motor or generator. Background technique [0002] In Patent Document 1 Figure 7 An example of "annular α-turn coil having a curved surface" is described in , and it is described that the α-turn coil is made of a wire, an insulating film covering the periphery of the wire, and a heat-adhesive coating that further covers the periphery of the insulating film. membrane composition. [0003] In Patent Document 2 Figure 4 and Figure 5 "Toroidal α-turn coil" is described in , for example, refer to Figure 5 The cross-sectional view of the ring-shaped α-turn coil is a coil formed by laminating the first coil layer located above and the second coil layer of the same shape and width as the first coil layer, "in order to achieve improved withstand voltage" , it can be seen that the upper and lower coil layers are misaligned with each other in the left and right directions. However, ther...
