上述した回転電機用コイルの成形の際、コイル形状によって差異はあるものの、回転電機用コイルのコイルエンド部には相当な負荷がかかり、素線崩れが発生してしまうことがある。素線崩れは見栄えが悪くなるだけでなく、テーピングする際に空隙を作ってしまう原因となりうる。空隙が生じることによりレジンが抜け落ちて放熱性能が悪化し、冷却能力の低下を招いてしまう可能性があった。また、あまりに加工が厳しすぎるとテープの破断に至ってしまうことがある。   When the above-described coil for a rotating electrical machine is formed, although there is a difference depending on the coil shape, a considerable load is applied to the coil end portion of the coil for the rotating electrical machine, and the strand breakage may occur. The breakage of the strands not only makes the appearance worse, but can also cause gaps when taping. Due to the formation of voids, the resin may fall off and heat dissipation performance may deteriorate, leading to a decrease in cooling capacity. Further, if the processing is too severe, the tape may be broken.

そのため、現行の製造方法とほとんど変わらないにも関わらず、素線崩れの発生を効果的に抑制することが望まれていた。   For this reason, it has been desired to effectively suppress the breakage of the strands in spite of almost no change from the current manufacturing method.

以上のことから、本発明は、前述した問題に鑑み提案されたもので、現行の製造方法とほとんど変わらないにも関わらず、素線崩れの発生を効果的に抑制することができる回転電機用コイルの製造方法を提供することを目的としている。   In view of the above, the present invention has been proposed in view of the above-described problems, and it is for a rotating electrical machine that can effectively suppress the occurrence of strand breakage in spite of almost the same as the current manufacturing method. It aims at providing the manufacturing method of a coil.

When this is done, it is prevented that a plurality of strands are scattered. Therefore, although it is almost the same as the current manufacturing method, the occurrence of strand breakage can be effectively suppressed, and the working efficiency is improved.

本発明の主な実施形態に係る回転電機用コイルの製造方法について、以下に説明するが、本発明は、以下の実施形態のみに限定されるものではない。   Although the manufacturing method of the coil for rotary electric machines which concerns on main embodiment of this invention is demonstrated below, this invention is not limited only to the following embodiment.

［主な実施形態］
本発明の主な実施形態に係る回転電機用コイルの製造方法について、図１に基づいて説明する。 [Main embodiments]
The manufacturing method of the coil for rotary electric machines which concerns on main embodiment of this invention is demonstrated based on FIG.

本実施形態に係る回転電機用コイルの製造方法であるコイルエンド部の成形方法では、複数の素線からなる回転電機用コイルのコイルエンド部を成形機（フォーミングマシン）で成形する前に、このコイルエンド部のＵ字状角部をなすナックル部に対応する箇所の外周部に熱収縮テープを巻き、これに対し加熱処理を実施する。これにより、コイルエンド部のナックル部に対応する箇所にあっては、複数の素線が熱収縮テープで固くまとめられることになる。   In the method for forming a coil end portion, which is a method for manufacturing a coil for a rotating electrical machine according to this embodiment, before the coil end portion of a coil for a rotating electrical machine made of a plurality of strands is formed by a molding machine (forming machine), A heat-shrinkable tape is wound around the outer peripheral portion corresponding to the knuckle portion forming the U-shaped corner portion of the coil end portion, and heat treatment is performed on this. Thereby, in the part corresponding to the knuckle part of a coil end part, a some strand is tightly bundled with a heat shrink tape.

前記熱収縮テープとして、例えば、加熱条件で収縮するが回転電機用コイルなどとの反応性が無く、加熱処理後であっても容易に剥がすことが可能な素材のテープであって、ポリエステル製テープを用いることが好ましい。   As the heat shrinkable tape, for example, a tape made of a material that shrinks under heating conditions but has no reactivity with a coil for a rotating electrical machine and can be easily peeled even after heat treatment, and is made of polyester Is preferably used.

加熱処理条件として、熱収縮テープが収縮する温度に保持可能な恒温槽内に前記回転電機用コイルを所定時間（例えば１時間）保持することが好ましい。   As the heat treatment condition, it is preferable to hold the rotating electrical machine coil for a predetermined time (for example, 1 hour) in a constant temperature bath that can be held at a temperature at which the heat shrinkable tape contracts.

続いて、成形機により、拡げや曲げ、ねじりといった加工が前記回転電機用コイルに施されて所定の形状に成形される。回転電機用コイルは、所定の形状をなすコイルサイド部およびコイルエンド部を有する。回転電機用コイル１０のコイルエンド部１０ａは、例えば、図１に示すように、ナックル部１０ａａと、一端側がナックル部１０ａａと接続し他端側がコイルサイド部１０ｂと接続する斜辺部（傾斜部）１０ａｂとを有する。ナックル部１０ａａは、Ｕ字状角部をなしている。なお、コイルサイド部１０ｂは、直線状に延在する形状をなしている。   Subsequently, processing such as expansion, bending, and twisting is performed on the coil for the rotating electrical machine by a molding machine, and is molded into a predetermined shape. The coil for rotating electrical machines has a coil side portion and a coil end portion having a predetermined shape. For example, as shown in FIG. 1, the coil end portion 10 a of the rotating electrical machine coil 10 includes a knuckle portion 10 aa and an oblique side portion (inclined portion) in which one end side is connected to the knuckle portion 10 aa and the other end side is connected to the coil side portion 10 b. 10ab. The knuckle part 10aa forms a U-shaped corner. In addition, the coil side part 10b has comprised the shape extended linearly.

続いて、成形後の前記回転電機用コイル１０から前記熱収縮テープが剥がされる。   Subsequently, the heat-shrinkable tape is peeled off from the molded electric machine coil 10 after molding.

上述した手順で所定の形状に成形された回転電機用コイルは、図１に示すように、ステータ１４のスロットに回転電機用コイル１０のコイルサイド部１０ｂが挿入された状態で固定される。すなわち、ステータ１４から回転電機用コイル１０のコイルエンド部１０ａが突出した状態で固定される。なお、符号１２は、ステータ１４に取り付ける前であって、成形機による成形時に、回転電機用コイル１０のコイルエンド部１０ａのナックル部１０ａａに対応する箇所の外周部１０ａａａを覆い、加熱処理で収縮する熱収縮テープを示している。   As shown in FIG. 1, the rotating electrical machine coil molded into a predetermined shape by the above-described procedure is fixed in a state where the coil side portion 10 b of the rotating electrical machine coil 10 is inserted into the slot of the stator 14. In other words, the coil end portion 10 a of the rotating electrical machine coil 10 is fixed in a state of protruding from the stator 14. Reference numeral 12 denotes a portion before being attached to the stator 14 and covers the outer peripheral portion 10aa of the portion corresponding to the knuckle portion 10aa of the coil end portion 10a of the coil 10 for the rotating electrical machine when being molded by the molding machine, and contracted by heat treatment. Shows heat shrink tape.

したがって、本実施形態によれば、ナックル部１０ａａに対応する箇所の外周部１０ａａａに熱収縮テープ１２を巻き、この熱収縮テープ１２が加熱処理で収縮して回転電機用コイルを構成する複数の素線が固くまとめられることから、回転電機用コイル１０を所定の形状に成形するときに、複数の素線がばらけることが防止される。よって、現行の製造方法とほとんど変わらないにも関わらず、素線崩れの発生を効果的に抑制することができ、作業効率が向上する。また、コイルエンド部１０ａを成形した後に加熱処理された熱収縮テープ１２を容易に剥がせることから、次工程であるワニスの含浸や、マイカテープの巻回をコイルエンド部１０ａの全体に対して確実に行うことができる。また、絶縁層内の空隙の発生を防止することできる。これにより、熱伝導性能が向上し、巻線の温度低下が可能となる。   Therefore, according to the present embodiment, the heat-shrinkable tape 12 is wound around the outer peripheral portion 10aaa corresponding to the knuckle portion 10aa, and the heat-shrinkable tape 12 is contracted by the heat treatment to form a plurality of elements constituting the coil for the rotating electrical machine. Since the wires are tightly gathered, it is possible to prevent the plurality of strands from being scattered when the rotating electrical machine coil 10 is formed into a predetermined shape. Therefore, although it is almost the same as the current manufacturing method, the occurrence of strand breakage can be effectively suppressed, and the working efficiency is improved. In addition, since the heat-shrinkable tape 12 that has been heat-treated after the coil end portion 10a is formed can be easily peeled off, varnish impregnation and winding of mica tape, which are the next steps, are performed on the entire coil end portion 10a. It can be done reliably. Moreover, generation | occurrence | production of the space | gap in an insulating layer can be prevented. Thereby, the heat conduction performance is improved, and the temperature of the winding can be lowered.

本実施例に係る回転電機用コイルの製造方法の作用効果を確認するための確認試験について、図２〜図４を用いて以下に説明するが、本発明は以下に説明する確認試験のみに限定されるものではない。   Although the confirmation test for confirming the effect of the manufacturing method of the coil for rotary electric machines which concerns on a present Example is demonstrated below using FIGS. 2-4, this invention is limited only to the confirmation test demonstrated below. Is not to be done.

＜試験体＞
図２Ａに示すように、直方体形状をなす素線（金属板）２１を複数積層して積層体２０（回転電機用コイルの模擬品）とし、回転電機用コイルのコイルエンド部におけるナックル部に対応する箇所として積層体２０の中央部２０ａの外周部（上面部２０ａａおよび側面部２０ａｂおよび下面部２０ａｃ）を熱収縮テープ２２で覆い、１５０℃の恒温槽内に１時間保持する条件で加熱処理を実施する。これにより、熱収縮テープ２２が収縮して、複数の素線２１からなる積層体２０の中央部２０ａ（回転電機用コイルのコイルエンド部におけるナックル部に対応する箇所）が固くまとめられることになる。 <Test body>
As shown in FIG. 2A, a plurality of rectangular parallelepiped strands (metal plates) 21 are laminated to form a laminated body 20 (simulated product of a rotating electrical machine coil) corresponding to a knuckle portion in a coil end portion of the rotating electrical machine coil. The outer periphery (upper surface portion 20aa, side surface portion 20ab, and lower surface portion 20ac) of the central portion 20a of the laminate 20 is covered with the heat-shrinkable tape 22, and the heat treatment is performed for 1 hour in a constant temperature bath at 150 ° C. carry out. As a result, the heat shrinkable tape 22 contracts, and the central portion 20a of the laminate 20 composed of the plurality of strands 21 (the portion corresponding to the knuckle portion in the coil end portion of the rotating electrical machine coil) is tightly gathered. .

なお、前記熱収縮テープ２２として、Dunstone社製の収縮率２０％のものを使用した。   As the heat shrinkable tape 22, one having a shrinkage rate of 20% manufactured by Dunstone was used.

続いて、図２Ｂに示すように、中央部２０ａが支点となるように一方の端部２０ｂ側から略中央部２０ａに亘って成形機（図示せず）で固定し、拡げや曲げ、ねじりといった加工を施して中央部２０ａを略Ｖ字状に成形する。   Subsequently, as shown in FIG. 2B, the center portion 20a is fixed by a molding machine (not shown) from one end 20b side to the substantially center portion 20a so that the center portion 20a becomes a fulcrum, and is expanded, bent, twisted, etc. Processing is performed to form the central portion 20a into a substantially V shape.

続いて、図２Ｃに示すように、成形後の積層体２０から熱収縮テープ２２を剥がして得られたものを試験体２０Ａとする。   Then, as shown to FIG. 2C, what was obtained by peeling the heat-shrink tape 22 from the laminated body 20 after shaping | molding is used as the test body 20A.

＜比較体＞
比較体の製造方法においては、熱収縮テープで積層体の中央部を覆う工程と、加熱処理を施す工程と、熱収縮テープを剥がす工程とを省き、これらの工程以外は、試験体２０Ａとほぼ同様な手順で、図４に示すように、試験体２０Ａとほぼ同じＶ字状に成形し、得られたものを比較体２０Ｂとした。すなわち、直方体形状をなす素線２１を複数積層してなる積層体２０を成形機で試験体２０Ａと同様に、拡げや曲げ、ねじりといった加工を施しＶ字状に成形し、得られたものを比較体２０Ｂとする。 <Comparator>
In the method for producing the comparative body, the step of covering the central portion of the laminate with the heat shrink tape, the step of performing the heat treatment, and the step of peeling off the heat shrink tape are omitted. Except for these steps, the test body 20A is almost the same. In the same procedure, as shown in FIG. 4, it was molded into a V shape substantially the same as that of the test body 20A, and the resultant was used as a comparative body 20B. That is, a laminated body 20 formed by laminating a plurality of strands 21 having a rectangular parallelepiped shape is processed into a V shape by performing processing such as expansion, bending, and twisting with a molding machine in the same manner as the test body 20A. It is set as a comparative body 20B.

＜試験方法＞
上述の試験体２０Ａに対し、応力が集中し易く寸法誤差が最も大きくなる箇所であって、中央部に対応するＡ−Ａ´線に沿う断面にて、高さ方向の大きさおよび幅方向の大きさをそれぞれ計測し、計測結果と設計時の寸法（成形前の寸法）とから寸法誤差を算出した。比較体２０Ｂに対しても、試験体２０Ａと同様、応力が集中し易く寸法誤差が最も大きくなる箇所であって、中央部に対応するＢ−Ｂ´線に沿う断面にて、高さ方向の大きさおよび幅方向の大きさをそれぞれ計測し、計測結果と設計時の寸法（成形前の寸法）とから寸法誤差を算出した。 <Test method>
With respect to the above-described test body 20A, the stress is likely to concentrate and the dimensional error is the largest, and in the section along the line AA ′ corresponding to the central portion, the size in the height direction and the width direction Each size was measured, and a dimensional error was calculated from the measurement result and the design dimension (dimension before molding). Similarly to the test body 20A, the comparative body 20B is a part where stress is easily concentrated and the dimensional error is the largest, and in the cross section along the line BB ′ corresponding to the center part, The size and the size in the width direction were measured, respectively, and the dimensional error was calculated from the measurement result and the design dimensions (dimensions before molding).

試験体２０Ａの寸法誤差は、図３に示すように、比較体２０Ｂの寸法誤差と比べて、幅（幅方向）および高さ（高さ方向）の何れも小さいことが確認された。すなわち、応力が集中する回転電機用コイルのコイルエンド部のナックル部に対応する箇所を熱収縮テープで覆い、加熱処理した後に、所定の形状に成形し、熱収縮テープを剥がすだけで、現行の製造方法とほとんど変わらないにも関わらず、素線崩れの発生を効果的に抑制することができることが確認された。   As shown in FIG. 3, it was confirmed that both the width (width direction) and the height (height direction) of the dimensional error of the test body 20A were smaller than the dimensional error of the comparative body 20B. That is, the portion corresponding to the knuckle portion of the coil end portion of the rotating electrical machine coil where stress is concentrated is covered with heat shrink tape, heated, molded into a predetermined shape, and the heat shrink tape is simply peeled off. Although it is almost the same as the manufacturing method, it has been confirmed that the occurrence of strand breakage can be effectively suppressed.

本発明に係る回転電機用コイルの製造方法は、現行の製造方法とほとんど変わらないにも関わらず、素線崩れの発生を効果的に抑制することができるので、発電機の固定子絶縁技術のうち、固定子鉄心外部絶縁の空隙を防止する手法、特に、固定子コイルの成形前の空隙防止方法において、産業上、極めて有益に利用することができる。   Although the method for manufacturing a coil for a rotating electrical machine according to the present invention is almost the same as the current manufacturing method, it is possible to effectively suppress the occurrence of strand breakage. Among them, the method for preventing voids in the outer insulation of the stator core, in particular, the method for preventing voids before forming the stator coil, can be used extremely beneficially industrially.
