Abstract

PURPOSE:To save the manufacturing time by a method wherein a slot is cut in the longitudinal direction of a conductor in case of forming the conductor to improve the permeability of varnish. CONSTITUTION:A slot of V type and the like is cut on a part of periphery of a conductor in case of forming the conductor. By means of cutting the V type slot, the permeability of varnish may be improved to facilitate the workability saving the manufacturing time.

Description

【発明の詳細な説明】 本発明はコイルの絶縁法に関する。[Detailed description of the invention] The present invention relates to a coil insulation method.

従来フェス塗り作業に際して、導体を数枚合わせ、この
合せ目を利用してフェノの浸透性を良くしていた。Conventionally, when painting a phenol, several conductors were put together and the joints were used to improve the permeability of the phenol.

この種のコイルは、導体を数枚合わせるため。This type of coil is made by combining several conductors.

成形しながら導体を合わせなければならず、製造時間が
大巾に掛かつていた。The conductors had to be matched while molding, which added to the manufacturing time.

また、導体自体にキズがつく欠点が生じていた。In addition, there was a drawback that the conductor itself was scratched.

本発明の目的は、導体を加工することによシ製造時間を
短縮できるコイルの絶縁法を提供するに金るＯ 本発明の特徴は、導体に複数個の溝を設けた点にある。SUMMARY OF THE INVENTION An object of the present invention is to provide a method of insulating a coil that can shorten manufacturing time by processing a conductor.The present invention is characterized in that a plurality of grooves are provided in a conductor.

以下、本発明の実施例を図面を用いて説明する。Embodiments of the present invention will be described below with reference to the drawings.

At the time of molding the conductor 1, a V-shaped groove 3 is cut in a part of the outer peripheral surface as shown in FIGS. 2 and 3. The phenol passes through this V-shaped groove 3 and penetrates into the entire conductor.
