。[Prior Art] Generally, when winding a winding around a rotor of a rotating machine, a second
As shown in the figure, a slot 2 is formed in the core of the rotor 1, and a winding 3 is fitted into the slot 2. In this case, it is necessary to protect the surface of the winding 3 installed in the slot 2 and prevent carbon dust generated from the brush from accumulating on the surface of the winding 3 exposed at the opening of the slot 2. In order to prevent this, the surface of the winding 3 has been conventionally covered with aramid paper 4.
［発明が解決しようとする課題］
ところが、回転子１の表面に形成されたスロット２は幅
の狭い溝であるため、このスロット２の開口部に合せて
テープ状に切断されたアラミツド紙４を手作業で挿入し
て行く作業は極めて工数のかかる面倒な作業であった。[Problems to be Solved by the Invention] However, since the slot 2 formed on the surface of the rotor 1 is a narrow groove, it is difficult to cut the aramid paper 4 into a tape shape to fit the opening of the slot 2. The manual insertion process was extremely time-consuming and troublesome.

ボンダスト等が溜り易い欠点もおった。Furthermore, even if the aramid paper 4 is inserted to match the width of the slot 2, the edges of the aramid paper 4 and the slot 2, and the winding 3
There was also a drawback that gaps and stepped portions 5 were likely to be formed between the ends of the carbon fibers, and carbon dust and the like were likely to accumulate in these portions.
ざらに、アラミツド紙４は、樹脂を含浸させてはいるも
のの紙製品であり、その熱伝導性が低く、巻線３表面の
放熱効果を悪化させる問題点もあった。Generally speaking, the aramid paper 4 is a paper product, although it is impregnated with resin, and has a problem of low thermal conductivity, which deteriorates the heat dissipation effect of the surface of the winding 3.

転機を提供することを目的とする。The present invention solves the problems of the prior art as described above, and can easily protect the winding surface without requiring labor-intensive work such as inserting aramid paper. It is an object of the present invention to provide a rotating machine having winding protection means that is excellent in preventing carbon dust from accumulating on the surface and in heat dissipation from the winding surface.

徴とするものである。[Means for Solving the Problems] The rotating machine of the present invention has a winding wire installed in a slot formed in a rotor, and a dixo-based resin is applied and hardened on the surface of the winding wire, and the slot opening and the winding wire are coated on the surface of the winding wire and hardened. It is characterized by having a coated surface.

ともできる。In addition, the winding surface and the edge of the slot can be easily and reliably closed, and the product of carbon dust, etc.) can be reduced.
ざらに、アラミツド紙に比較して熱伝導性の良いチクソ

する。Furthermore, the use of thixo-based resin, which has better thermal conductivity than aramid paper, also improves the efficiency of heat dissipation from the winding surface.
［実施例］ 以下、本発明の実施例を第１図により説明する。[Example] Embodiments of the present invention will be described below with reference to FIG.
なお、第２図の従来技術と同一の部材については同一符
号を付し、説明は省略する。Note that the same members as those in the prior art shown in FIG. 2 are designated by the same reference numerals, and explanations thereof will be omitted.
本実施例において、スロット２内に装着された巻線３の

ており、スロット２内の巻線３の表面が確実に被覆され
ている。In this embodiment, a hardened layer of thixo-based resin 10 is formed on the surface of the winding 3 installed in the slot 2. The hardened layer of the thixo-based resin 10 is made by applying a highly viscous liquid resin with a brush after the winding 3 is installed in the slot 2.
It is applied to the surface of the winding wire 3 using a spatula, spray, or other means, and then hardened. In this case, the thixo-based resin 10 is applied from one edge of the slot 2 to the other edge, ensuring that the surface of the winding 3 within the slot 2 is coated.
このようなチクソ系レジン１０の塗布作業は、アラミツ
ド紙４のような幅の決ったものを幅の狭いスロット２内

の被覆作業を迅速に行うことが可能となる。床だ、粘度
の高いチクソ系レジンは塗布時にその厚さを容易に調整
できるので、スロット装着時における巻線３表面の凹凸
を解消できる利点もある。The work of applying the thixo-based resin 10 is much easier than the work of inserting something with a fixed width, such as aramid paper 4, into the narrow slot 2, and it speeds up the work of covering the windings. It becomes possible to do so. Since the thickness of the high-viscosity thixo-based resin can be easily adjusted during application, it also has the advantage of eliminating unevenness on the surface of the winding 3 when installing the slot.

線３との隙間に人込み、スロット２の縁と巻線３の表面
との間に形成される段部をなだらかに埋めることになる
ので、スロット２の縁にアラミツド紙のような段部が無
くなり、この部分にカーボンダスト等の異物の滞積が少
なくなり、回転機の信頼性も向上する。In addition, the highly viscous thixo-based resin 10 coats the surface of the winding 3 at the time of application, and at the same time crowds into the gap between the slot 2 and the winding 3, causing the edge of the slot 2 and the surface of the winding 3 to overlap. Since the step formed in between is gently filled, there is no step like aramid paper on the edge of the slot 2, and there is less accumulation of foreign matter such as carbon dust in this area, which improves the reliability of the rotating machine. Sexuality also improves.

比較すれば放熱性能に優れているので、巻線の冷却効率
が向上し、それに伴う放熱面積縮小による回転子の小型
化、回転機内部の通風路の縮小など、回転機の小型軽母
化に大きく寄与することができる。In general, the thixo-based resin used in this example has superior heat dissipation performance compared to aramid paper, so the cooling efficiency of the windings is improved, and the resulting reduction in the heat dissipation area allows for smaller rotors and the interior of the rotating machine. This can greatly contribute to making rotating machines smaller and lighter, such as by reducing the ventilation ducts.

供できる効果がある。[Effects of the Invention] As described above, according to the present invention, the surface of the winding installed in the slot is coated with a hardened layer of thixo-based resin, which is easy to manufacture and highly reliable. This has the effect of providing a rotating machine that can be made smaller and lighter due to improved cooling efficiency.
