Abstract
Description
【発明の詳細な説明】 (イ)産業上の利用分野 この発明はマグネットコイルの製造方法に関する。[Detailed description of the invention] (b) Industrial application fields The present invention relates to a method of manufacturing a magnet coil.
(ロ)従来技術とその問題点

。(b) Prior art and its problems The conventional manufacturing method for magnetic coils is to form a coil by winding a predetermined amount of wire around a suitable core, and then remove the coil from the core and place it in a mold. , a method of impregnating and curing resin such as varnish was used.
この方法によると、捲回時線材に加わる巻き張力が巻芯

を必要とするコイルの製作に適さない問題がある。According to this method, the winding tension applied to the wire during winding is supported by the winding core, so when the winding core 2 is removed, especially in the case of a long rectangular coil 1 as shown in FIG. As shown in Figure 2, the center part may be depressed, or may swell as shown by the chain line, making it unsuitable for manufacturing coils that require precise dimensional accuracy.
この発明は、上記の問題点を解決し、寸法精度の良好な
コイルを製作し得る方法を提供することを目的としてい
る。The present invention aims to solve the above-mentioned problems and provide a method for manufacturing a coil with good dimensional accuracy.

であり、従来のごとき変形(第2図参照)がない。(B) Embodiment FIGS. 2 and 3 show an embodiment of the present invention. FIG. 2 shows the coil 1 wound around the winding core 2 as shown in FIG. This state is shown in a state where it is placed in a mold 3 without being removed, and this state 1 is impregnated with burnt varnish or the like, and after curing is completed, it is taken out from the mold 3 and the winding core 2 is removed. Figure 4 shows the coil 1 manufactured in this way.
Therefore, there is no deformation as in the conventional case (see Fig. 2).
(ホ) 効 宋
以−にのように、この発明によれは、樹脂の含浸・硬化
後に巻芯を取り外すので、捲回時線材にかかつていた応
力は硬化した樹脂によって支えられる。(E) Effects As in Song Yi, this invention removes the winding core after impregnating and hardening the resin, so that the stress that is applied to the wire during winding is supported by the hardened resin.
したがって、コイルの変形がなく、寸法精度の良いコイ
ルを製作することができる。Therefore, it is possible to manufacture a coil with good dimensional accuracy without deformation of the coil.
また、巻芯とモールド用中型を兼用させるため、工程が
短縮される効果もある。Furthermore, since the winding core and the medium die for molding are used together, the process can be shortened.
