（イ）産業上の利用分野
本発明は電磁石用コイルの外装方法に関し、更に詳細に

コイルの外周を樹脂で外装する方法に関する。DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a method for wrapping an electromagnetic coil, and more specifically, it relates to a method for wrapping an electromagnet coil, and more specifically, the outer periphery of the coil is coated with resin by using the rotational centrifugal force of the coil and the surface tension of liquid resin. Concerning how to exteriorize.
（ロ）従来技術
電磁石用コイルの外周の電気絶縁には樹脂の特性からし
て樹脂外装が望ましく、このため従来から樹脂による種
々の外装方法が行なわれていた。(b) Prior Art For electrical insulation of the outer periphery of an electromagnetic coil, resin sheathing is desirable due to the characteristics of resin, and for this reason, various methods of sheathing with resin have been used in the past.
ところで樹脂で外装する場合コイル緊線に圧力を加えな
いでコイル巻線の外周部のみ均一に封止する必要がある
が、従来の方法では品質の低下、性能の低下が多々あっ
た。By the way, when sheathing with resin, it is necessary to uniformly seal only the outer periphery of the coil winding without applying pressure to the coil wire, but conventional methods often result in deterioration in quality and performance.

った。In other words, the conventional packaging method is as follows: (1) As shown in Fig. 1, a coil bobbin a with a coil wound around the outer periphery is placed in two upper and lower molds C9d, and the inlet is inserted into the mold C9d. (11) As shown in Fig. 2, the method of injecting and molding a hot melted solid resin material (g) from e. Method of dipping into resin material g placed in G11
) As shown in Fig. 6, after placing a coil bobbin a with a coil winding around its outer periphery into a hollow case i, a resin material g is injected from the gap between the case 1 and the coil bobbin a using an injection device J. (lv) A method in which a tape impregnated with a resin material is wrapped around the outside of the coil winding, and then passed through a curing device to melt the resin contained in the tape and package it, and (V) A method in which a tape impregnated with a resin material is wrapped around the outside of the coil winding, and the resin contained in the tape is melted out and packaged. For limited use, such as indoor use where there is no room, there are methods such as wrapping resin tape around it.

い場合がある。However, in method (1) above, high pressure must be applied when filling the resin material into the mold, so the first method is
As shown by 1 in the figure, during filling, the resin material enters the gap between the flange of the coil bobbin a and the coil b, compressing the coil wire and causing problems such as interlayer short circuits and disconnections. In method 11), when the coil is removed from the container, the resin material not only sags as shown in Figure 2 [A] while drying, but also causes the surface to not be kept uniform and may even harden. Later, as shown by m in Fig. 2 [B'], the sagging part hardens and becomes a defective product, which requires additional processing such as masking. There is a problem in that it is necessary to provide a means to prevent leakage of the liquid resin between the parts, and in addition, in the method 4v) above, the direction in which the resin material melts and the wrapping of the tape may vary depending on the thickness of the resin. In some cases, unevenness occurs in the resin, resulting in areas that cannot be sealed, and the resin may not be able to fully demonstrate its performance.

In the figure, a pair of rotary shafts 5 and 4, which are inserted into one end of a coil bobbin a and support the coil bobbin a, are rotatably attached to the frame 2 on the same axis. The rotating shaft 4 can be rotated by a motor 7 via gears 5 and 6.

いる。A coating device 8 is provided adjacent to the outer periphery of the coil attached to the rotating shaft. This coating device is equipped with a nozzle member 9 having an elongated nozzle opening (not shown) extending along the axial direction of the coil and facing toward the outer circle of the coil.

（Ｃ） 更には均一膜で封止するので外装樹脂の省資源
にもなる。(C) Furthermore, since sealing is performed with a uniform film, resources for the exterior resin can be saved.
８）樹脂材を多層に形成するのも容易である。8) It is also easy to form the resin material into multiple layers.
（ｅ） 本発明の方法で使用する液状樹脂材としては接
