Abstract

PURPOSE:To form a coil with excellent accuracy in dimensions by placing a coil having the core in the mold die at the time of winding a coil and removing the core after impregnation and hardening. CONSTITUTION:A coil 1 wound around a core 2 is housed in the mold 3 without removing the core 2 and it is impregnated with varnish under this condition. After it is hardened, the coil is removed from the mold 3 and core is then removed. Since the core 2 is removed after impregnation of resin and hardening, a stress applied on the wire at the time of winding is supported by the hardened resin. Accordingly, the coil 1 is not deformed and the coil 1 having excellent accuracy in dimensions can be manufactured.

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.

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.

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).

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.
