Description

本発明は、平角線をエッジワイズ方向に巻いて形成される界磁コイルと、その界磁コイルの製造方法に関する。   The present invention relates to a field coil formed by winding a rectangular wire in an edgewise direction, and a method for manufacturing the field coil.

従来、平角線をエッジワイズ方向に巻回して形成される界磁コイルが知られている（特許文献１、特許文献２参照）。
この界磁コイルの製造方法を図５に基づいて説明する。
まず、図５（ａ）に示す様に、１本の平角線１００の両端部をそれぞれ巻芯１１０にセットする。
続いて、同図（ｂ）〜（ｄ）に示す様に、巻芯１１０を回転させながら、巻芯１１０の周囲に平角線１００をエッジワイズ方向に巻き取る。
所定回数巻き取ることにより、同図（ｅ）に示す様に、連結部１２０で連結された２個のコイル体が成形される。さらに、同図（ｆ）に示す様に、２個のコイル体を連結部１２０で折り返すことにより、直列に接続された２個の界磁コイル１３０が出来上がる。
特開２００６−２７１１２１号公報 特公平４−４９３３６号公報 Conventionally, a field coil formed by winding a rectangular wire in an edgewise direction is known (see Patent Document 1 and Patent Document 2).
The manufacturing method of this field coil is demonstrated based on FIG.
First, as shown in FIG. 5A, both ends of one flat wire 100 are set on the core 110, respectively.
Subsequently, as shown in FIGS. 4B to 4D, the rectangular wire 100 is wound around the core 110 in the edgewise direction while the core 110 is rotated.
By winding up a predetermined number of times, two coil bodies connected by the connecting portion 120 are formed, as shown in FIG. Further, as shown in FIG. 5 (f), two field coils 130 connected in series are completed by folding back two coil bodies at the connecting portion 120.
JP 2006-271121 A Japanese Patent Publication No. 4-49336

上記の方法で製造された界磁コイルは、図６に示す様に、巻き始めの端部（コイル端部１４０と呼ぶ）がストレート形状であり、磁極１５０（図７参照）に嵌め合わされた状態で、図示上方へ真っ直ぐ引き出されている。このため、図７に示す様に、コイル端部１４０とブラシ１６０とを電気的に接続する際に、コイル端部１４０とブラシ１６０との位置が周方向にずれていると、コイル端部１４０をブラシ側へ曲げる必要が生じる。しかし、平角線１００をエッジワイズ方向に曲げるのには大きな荷重を必要とするため、コイル体を成形した後にコイル端部１４０の曲げ加工を行うと、成形されたコイル体が変形したり、被膜付きコイルを使用する場合には被膜が破れる恐れがある。
また、上記の製造方法では、１本の平角線１００から２個の界磁コイル１３０が直列に繋がった状態で製造される。この場合、成形された界磁コイル１３０を磁極１５０に組み付ける際に、連続した２個の界磁コイル１３０を同時に磁極１５０の外周に嵌め合わせる必要があるため、高い寸法精度が要求される。 As shown in FIG. 6, the field coil manufactured by the above method has a straight end at the winding start (referred to as coil end 140) and is fitted to the magnetic pole 150 (see FIG. 7). Thus, it is drawn straight upward in the figure. For this reason, as shown in FIG. 7, when the coil end 140 and the brush 160 are electrically connected, if the positions of the coil end 140 and the brush 160 are shifted in the circumferential direction, the coil end 140. Needs to be bent toward the brush. However, since a large load is required to bend the rectangular wire 100 in the edgewise direction, if the coil end portion 140 is bent after forming the coil body, the formed coil body may be deformed or coated. When using an attached coil, the coating may be broken.
In the manufacturing method described above, two field coils 130 are connected in series from one rectangular wire 100. In this case, when assembling the molded field coil 130 to the magnetic pole 150, it is necessary to fit two continuous field coils 130 to the outer periphery of the magnetic pole 150 at the same time, and thus high dimensional accuracy is required.

上記の理由から、コイル体を成形した後にコイル端部１４０を曲げ加工する方法は採用されておらず、コイル端部１４０がストレート形状のまま使用されている。この場合、コイル端部１４０の位置が限定される（位置自由度が小さい）ため、コイル端部１４０とブラシ１６０との位置が周方向にずれていると、両者の間を電気的に接続するための別部材が必要となり、部品点数が増加してコストアップを招いていた。
本発明は、上記事情に基づいて成されたもので、その目的は、平角線をエッジワイズ方向に巻回して形成された界磁コイルから引き出されるコイル端部の位置自由度を向上できる回転電機、及び界磁コイルの製造方法を提供することにある。 For the above reason, the method of bending the coil end portion 140 after forming the coil body is not adopted, and the coil end portion 140 is used in a straight shape. In this case, since the position of the coil end portion 140 is limited (positional freedom is small), if the positions of the coil end portion 140 and the brush 160 are shifted in the circumferential direction, they are electrically connected. For this reason, a separate member is required, which increases the number of parts and increases the cost.
The present invention has been made based on the above circumstances, and an object of the present invention is to provide a rotating electrical machine capable of improving the position freedom of a coil end portion drawn from a field coil formed by winding a rectangular wire in an edgewise direction. And a method of manufacturing a field coil.

According to the above configuration, by arbitrarily selecting one point on R that is the starting point in the tangential direction, the drawing direction of the coil end can be appropriately changed, so that the degree of freedom of position of the coil end is improved.

図１（ａ）はヨークＡＳＳＹの展開図、同図（ｂ）はＡ−Ａ断面図、図２はヨークＡＳＳＹの軸方向平面図である。
本実施例の回転電機は、例えば、自動車用エンジンを始動するためのスタータモータであり、図１及び図２に示すヨークＡＳＳＹを備える。
ヨークＡＳＳＹは、磁気回路を形成するヨーク１と、このヨーク１の内周に固定される４個の磁極２と、各磁極２に組み付けられる４個の界磁コイル３とで構成される。 1A is a development view of the yoke ASSY, FIG. 1B is a cross-sectional view taken along the line AA, and FIG. 2 is a plan view in the axial direction of the yoke ASSY.
The rotating electrical machine of the present embodiment is, for example, a starter motor for starting an automobile engine, and includes a yoke ASSY shown in FIGS. 1 and 2.
The yoke assembly is composed of a yoke 1 forming a magnetic circuit, four magnetic poles 2 fixed to the inner periphery of the yoke 1, and four field coils 3 assembled to each magnetic pole 2.

ヨーク１は、強磁性体である鉄板を円筒形状に丸めて形成される。
磁極２は、図１（ｂ）に示す様に、界磁コイル３が嵌め合わされるボス部２ａと、ヨーク１との間に界磁コイル３を保持する鍔部２ｂとが設けられている。ボス部２ａは、図１（ａ）に示す様に、断面形状が長方形状を有し、角部がＲ形状に面取りされている。
４個の界磁コイル３は、２直列−２並列に接続されている。つまり、直列に接続された二個一組の界磁コイル３が二組設けられ、この二組が並列に接続されている。この界磁コイル３は、後述する製造方法により、平角線４（図３参照）をエッジワイズ方向に巻いて形成される。 The yoke 1 is formed by rolling an iron plate, which is a ferromagnetic material, into a cylindrical shape.
As shown in FIG. 1B, the magnetic pole 2 is provided with a boss portion 2 a into which the field coil 3 is fitted and a flange portion 2 b that holds the field coil 3 between the yoke 1. As shown in FIG. 1A, the boss portion 2a has a rectangular cross-sectional shape and a corner portion is chamfered into an R shape.
The four field coils 3 are connected in 2 series-2 parallel. That is, two sets of two field coils 3 connected in series are provided, and the two sets are connected in parallel. The field coil 3 is formed by winding a rectangular wire 4 (see FIG. 3) in an edgewise direction by a manufacturing method described later.

直列に接続された２個の界磁コイル３は、図１（ａ）に示す様に、電流が流れる方向の上流側である一方のコイル端部３ａがモータリード板５に接続され、電流が流れる方向の下流側である他方のコイル端部３ｂが正極ブラシ６のリード線６ａ（ピグテール）に接続されている。但し、一方のコイル端部３ａは、界磁コイル３を磁極２に組み付けた状態（図１に示す状態）で、ボス部２ａの角部に形成されるＲ形状の始点と終点との間に設定される任意の一点を起点として接線方向に引き出され、磁極２の軸方向（図示上下方向）に対し所定の傾き（傾斜角度θ１と呼ぶ）を有している。   In the two field coils 3 connected in series, as shown in FIG. 1A, one coil end 3a on the upstream side in the direction of current flow is connected to the motor lead plate 5, and the current flows. The other coil end 3 b which is the downstream side in the flowing direction is connected to the lead wire 6 a (pigtail) of the positive electrode brush 6. However, one coil end 3a is in a state where the field coil 3 is assembled to the magnetic pole 2 (the state shown in FIG. 1), between the R-shaped start point and end point formed at the corner of the boss 2a. It is drawn in the tangential direction from an arbitrary set point as a starting point, and has a predetermined inclination (referred to as an inclination angle θ1) with respect to the axial direction (vertical direction in the figure) of the magnetic pole 2.

同様に、他方のコイル端部３ｂは、界磁コイル３を磁極２に組み付けた状態で、ボス部２ａの角部に形成されるＲ形状の始点と終点との間に設定される任意の一点を起点として接線方向に引き出され、磁極２の軸方向に対し所定の傾き（傾斜角度θ２と呼ぶ）を有している。
なお、モータリード板５は、図２に示す様に、ヨーク１とエンドフレーム（図示せず）との間に固定されるグロメット７に保持されて、モータの外側に取り出された一端側の端部が図示しない電磁スイッチのモータ端子に接続されている。 Similarly, the other coil end 3b is an arbitrary point set between an R-shaped start point and an end point formed at the corner of the boss 2a with the field coil 3 assembled to the magnetic pole 2. Starting from the tangential direction and has a predetermined inclination (referred to as an inclination angle θ2) with respect to the axial direction of the magnetic pole 2.
As shown in FIG. 2, the motor lead plate 5 is held by a grommet 7 fixed between a yoke 1 and an end frame (not shown), and is taken out from one end of the motor. The part is connected to a motor terminal of an electromagnetic switch (not shown).

次に、界磁コイル３の製造方法を図３に基づいて説明する。
まず、２個の界磁コイル３を製造できるだけの所定の長さを有する１本の平角線４を準備し、同図（ａ）に示す様に、平角線４の両端部をそれぞれ巻芯８にセットする。この時、平角線４の一方（図示左側）の端部は、巻芯８との間に予め傾斜角度θ１に相当する角度α１を有する状態で巻芯８にセットされ、平角線４の他方の端部は、巻芯８との間に予め傾斜角度θ２に相当する角度β１を有する状態で巻芯８にセットされる。なお、左右両側の巻芯８は、それぞれ磁極２のボス部２ａと同一形状に設けられている。 Next, a method for manufacturing the field coil 3 will be described with reference to FIG.
First, one rectangular wire 4 having a predetermined length sufficient to manufacture two field coils 3 is prepared, and both ends of the rectangular wire 4 are respectively wound around the core 8 as shown in FIG. Set to. At this time, one end (left side in the drawing) of the flat wire 4 is set to the core 8 in advance with an angle α1 corresponding to the inclination angle θ1 between the flat wire 4 and the other end of the flat wire 4. The end is set on the core 8 in a state having an angle β1 corresponding to the inclination angle θ2 between the end 8 and the core 8 in advance. The left and right winding cores 8 are provided in the same shape as the boss 2a of the magnetic pole 2, respectively.

続いて、上記のセットされた状態を図示しないクランプ装置により保持したまま、同図（ｂ）〜（ｄ）に示す様に、左右両側の巻芯８をそれぞれ回転（図中右回転）させながら、巻芯８の周囲に平角線４をエッジワイズ方向に巻き取る。
所定回数巻き取った後、同図（ｅ）に示す様に、二つのコイル体を連結する連結部３ｃに折り曲げ用の治具９を当てて、この治具９を支点として図示矢印方向に折り曲げる。これにより、同図（ｆ）に示す様に、連結部３ｃを介して直列に接続された２個の界磁コイル３が出来上がる。この２個の界磁コイル３は、例えば、同図（ｇ）に示す様に、連結部３ｃに対して同一側に設けられている。図示矢印は磁束の流れ方向を示している。
この後、２個の界磁コイル３をヨーク１の内周に沿って配置できる様に、コイル全体に曲率を付けて終了する。 Subsequently, while the above set state is held by a clamping device (not shown), the cores 8 on both the left and right sides are respectively rotated (rotated right in the figure) as shown in FIGS. The rectangular wire 4 is wound around the winding core 8 in the edgewise direction.
After winding up a predetermined number of times, as shown in FIG. 5E, a bending jig 9 is applied to the connecting portion 3c that connects the two coil bodies, and the jig 9 is bent in the direction indicated by the arrow. . As a result, as shown in FIG. 5F, two field coils 3 connected in series via the connecting portion 3c are completed. The two field coils 3 are provided on the same side with respect to the connecting portion 3c, for example, as shown in FIG. The illustrated arrows indicate the flow direction of the magnetic flux.
Thereafter, the entire coil is curved so that the two field coils 3 can be arranged along the inner periphery of the yoke 1, and the process is finished.

（実施例１の効果）
上記の製造方法によれば、平角線４の両端部を巻芯８にセットする段階で、それぞれ傾斜角度θ１、θ２に相当する角度α１、β１を持たせているので、この状態から巻芯８の周囲に平角線４を巻き取ることにより、磁極２のボス部２ａに嵌め合わされるコイル形状の部分と同時に傾斜角度θ１、θ２を有するコイル端部３ａ、３ｂを形成できる。この場合、巻き取り工程の後にコイル端部３ａ、３ｂを曲げ加工する必要はないので、磁極２のボス部２ａに嵌め合わされるコイル形状の部分と、そのコイル形状の部分から引き出されたコイル端部３ａ、３ｂとの位置寸法精度を高く製造できる。また、被膜付きコイルを使用する場合には、被膜が破れる恐れもない。これにより、一方のコイル端部３ａとモータリード板５との間、および、他方のコイル端部３ｂと正極ブラシ６のリード線６ａとの間を別部材によって電気的に接続する必要がなく、部品点数を削減できることにより、コストダウンを実現できる。 (Effect of Example 1)
According to the above manufacturing method, the angles α1 and β1 corresponding to the inclination angles θ1 and θ2 are provided at the stage where both ends of the flat wire 4 are set on the core 8, respectively. The coil ends 3a and 3b having the inclination angles θ1 and θ2 can be formed at the same time as the coil-shaped portion fitted to the boss 2a of the magnetic pole 2 by winding the rectangular wire 4 around. In this case, since it is not necessary to bend the coil end portions 3a and 3b after the winding process, the coil-shaped portion fitted to the boss portion 2a of the magnetic pole 2 and the coil end drawn from the coil-shaped portion The positional dimensional accuracy with the parts 3a and 3b can be manufactured with high accuracy. Moreover, when using a coil with a coating, there is no possibility that the coating is broken. Thereby, it is not necessary to electrically connect between the one coil end 3a and the motor lead plate 5 and between the other coil end 3b and the lead wire 6a of the positive electrode brush 6 by another member. The cost can be reduced by reducing the number of parts.

また、１本の平角線４から直列に接続された２個の界磁コイル３を製造する場合は、１個の界磁コイル３を製造する場合と比較すると、２極間のピッチ誤差も含めて、より高い寸法精度が要求される。これに対し、本実施例では、コイル形状の部分と、そのコイル形状の部分から引き出されたコイル端部３ａ、３ｂとの位置寸法精度を高く製造できるだけでなく、コイル形状の部分に巻き崩れが発生しないため、高い寸法精度を確保できる。
さらに、本実施例の製造方法によれば、平角線４の両端部を巻芯８にセットする角度α１、β１を変更するだけで、コイル端部３ａ、３ｂの引き出し方向（傾斜角度θ１、θ２）を任意に設定できるため、設計自由度が向上する。 Further, when two field coils 3 connected in series from one rectangular wire 4 are manufactured, a pitch error between two poles is included as compared with the case where one field coil 3 is manufactured. Therefore, higher dimensional accuracy is required. On the other hand, in this embodiment, not only can the position accuracy of the coil-shaped portion and the coil end portions 3a, 3b drawn from the coil-shaped portion be manufactured with high accuracy, but the coil-shaped portion is not collapsed. Since it does not occur, high dimensional accuracy can be ensured.
Furthermore, according to the manufacturing method of the present embodiment, only by changing the angles α1 and β1 for setting both ends of the flat wire 4 to the winding core 8, the coil end portions 3a and 3b are pulled out (inclination angles θ1 and θ2). ) Can be set arbitrarily, improving the degree of design freedom.

図４は界磁コイル３の製造工程図である。
この実施例２は、一方の界磁コイル３と他方の界磁コイル３とを対称形状に巻き取った場合の一例である。この場合、図４（ａ）に示す様に、平角線４の一方の端部を巻芯８にセットする角度α１と、平角線４の他方の端部を巻芯８にセットする角度β１とが同一角度（α１＝β１）であり、同図（ｂ）〜（ｄ）に示す様に、左右両側の巻芯８をそれぞれ反対方向に回転させて、巻芯８の周囲に平角線４を巻き取る。
所定回数巻き取った後、同図（ｅ）に示す様に、二つのコイル体を連結する連結部３ｃに折り曲げ用の治具９を当てて、この治具９を支点として図示矢印方向に折り曲げる。これにより、同図（ｆ）に示す様に、連結部３ｃを介して直列に接続された２個の界磁コイル３が対称形状に出来上がる。この２個の界磁コイル３は、例えば、同図（ｇ）に示す様に、連結部３ｃを挟んで対向する位置に設けられている。図示矢印は磁束の流れ方向を示している。 FIG. 4 is a manufacturing process diagram of the field coil 3.
The second embodiment is an example in which one field coil 3 and the other field coil 3 are wound symmetrically. In this case, as shown in FIG. 4A, an angle α1 for setting one end of the flat wire 4 to the core 8 and an angle β1 for setting the other end of the flat wire 4 to the core 8. Are the same angle (α1 = β1), and as shown in FIGS. 4B to 4D, the cores 8 on both the left and right sides are rotated in opposite directions, and the rectangular wire 4 is formed around the core 8. Wind up.
After winding up a predetermined number of times, as shown in FIG. 5E, a bending jig 9 is applied to the connecting portion 3c that connects the two coil bodies, and the jig 9 is bent in the direction indicated by the arrow. . As a result, as shown in FIG. 5F, the two field coils 3 connected in series via the connecting portion 3c are made symmetrical. The two field coils 3 are provided, for example, at positions facing each other across the connecting portion 3c, as shown in FIG. The illustrated arrows indicate the flow direction of the magnetic flux.

また、実施例１及び実施例２では、一方のコイル端部３ａと他方のコイル端部３ｂの両方に傾斜角度θ１、θ２を持たせているが、一方のコイル端部３ａのみ、あるいは他方のコイル端部３ｂのみ、傾斜角度を持たせる様に製造することもできる。 (Modification)
