Description

本発明は、回転子または固定子を構成する電機子積層鉄心の平板導体コイルおよびその製造方法に関する。 The present invention relates to a flat conductor coil of an armature laminated iron core constituting a rotor or a stator and a method for manufacturing the same.

回転電機の電機子である例えば固定子積層鉄心は、その磁極部にコイルが装着されている。
磁極部へ装着するコイルとしては、従来から巻線が使用されており、磁極部へのコイルの装着は、磁極部に巻線を巻回することにより行われている。しかし、最近、コイルの占積率をより高くして銅損を低減し、固定子積層鉄心の高効率化または小型化等を図るため、巻線の代わりに平板導体を使用するものが提案されている（例えば、特許文献１参照）。このような、平板導体からなるコイルは、図５に示すように、平面視してコ字状に形成された平板導体片９０を、磁極部（図示しない）を跨ぐように両側のスロットに挿入し、開放した端部を平板導体接続片９１で接続して形成されている。 For example, a stator laminated iron core that is an armature of a rotating electric machine has a coil mounted on a magnetic pole portion thereof.
As a coil to be attached to the magnetic pole part, a winding has been used conventionally, and the coil is attached to the magnetic pole part by winding the winding around the magnetic pole part. However, recently, in order to reduce the copper loss by increasing the coil space factor and to increase the efficiency or miniaturization of the laminated stator core, a method using a flat conductor instead of the winding has been proposed. (For example, refer to Patent Document 1). As shown in FIG. 5, in such a coil made of a flat conductor, a flat conductor piece 90 formed in a U shape in plan view is inserted into slots on both sides so as to straddle a magnetic pole part (not shown). The open ends are connected by a flat conductor connecting piece 91.

特開２００５−１６０１４３号公報JP-A-2005-160143

しかしながら、前記した平板導体からなるコイルは、平板導体片９０の開放した端部に、平板導体接続片９１を位置合わせしたうえで、平板導体片９０と平板導体接続片９１を電気的に接続する必要がある。このため、平板導体からなるコイルの形成には、多くの手間がかかり、コスト高にもなる。
また、平板導体片９０と平板導体接続片９１との位置ずれに起因する抵抗値の変化または相間絶縁不良の発生が懸念される問題もある。 However, the coil made of the above-described flat conductor electrically connects the flat conductor piece 90 and the flat conductor connecting piece 91 after aligning the flat conductor connecting piece 91 with the open end of the flat conductor piece 90. There is a need. For this reason, it takes a lot of work to form a coil made of a flat conductor, and the cost is increased.
Further, there is a problem that a change in resistance value due to a positional deviation between the flat conductor piece 90 and the flat conductor connecting piece 91 or an occurrence of an interphase insulation failure may occur.

本発明はかかる事情に鑑みてなされたもので、電機子積層鉄心の磁極部に、組み立て手間を要することなく装着でき、併せて従来のような平板導体片と平板導体接続片との接続が不要で位置ずれを生じない電機子積層鉄心の平板導体コイルおよびその製造方法を提供することを目的とする。 The present invention has been made in view of such circumstances, and can be mounted on the magnetic pole portion of the armature laminated core without requiring assembly work, and at the same time, there is no need to connect a flat plate conductor piece and a flat plate conductor connection piece as in the prior art. It aims at providing the flat conductor coil of the armature laminated core which does not produce position shift, and its manufacturing method.

前記目的に沿う第１の発明に係る電機子積層鉄心の平板導体コイルは、電機子積層鉄心の磁極部に、平板導体を螺旋状に巻回して装着した平板導体コイルであって、
導体板の幅方向の一端からおよび他端からともに他方側の板端の手前位置に終端部が至るスリットを交互に所定ピッチでかつ平行に繰り返し設けて、前記スリットによって形成される各導体部が連続した前記平板導体が形成され、前記導体板に前記各スリットの終端部を結ぶ線を折り曲げ線として、隣り合う前記導体部に交互に谷折り曲げと山折り曲げがなされて、螺旋状に形成された前記平板導体コイルが形成されている。 The flat conductor coil of the armature laminated core according to the first aspect of the present invention is a flat conductor coil in which a flat conductor is wound around a magnetic pole portion of the armature laminated iron core,
Each of the conductor parts formed by the slits is repeatedly provided in parallel with a predetermined pitch and in parallel with slits that reach the terminal part from the one end in the width direction of the conductor plate and from the other end to the position before the other plate end. The continuous flat plate conductor is formed, and a line connecting the end portion of each slit to the conductor plate is used as a folding line, and the adjacent conductor portions are alternately folded in a valley and a mountain and formed in a spiral shape. The flat conductor coil is formed.

第１の発明に係る電機子積層鉄心の平板導体コイルにおいて、螺旋状に巻かれた前記平板導体コイルを構成する前記各導体部間に、別の螺旋状に巻かれた平板導体コイルを構成する導体部を入れ込み、螺旋状に形成された前記平板導体コイルを多層に形成することが好ましい。 In the flat conductor coil of the armature laminated iron core according to the first aspect of the present invention, another spirally wound flat conductor coil is formed between the conductor portions constituting the spirally wound flat conductor coil. It is preferable to insert the conductor part and form the spirally formed flat conductor coil in multiple layers.

前記目的に沿う第２の発明に係る電機子積層鉄心の平板導体コイルの製造方法は、電機子積層鉄心の磁極部に、平板導体を螺旋状に巻回してなる平板導体コイルの製造方法であって、
導体板の幅方向の一端からおよび他端からともに他方側の板端の手前位置に終端部が至るスリットを交互に所定ピッチでかつ平行に繰り返して設け、前記スリットによって形成される各導体部が連続した前記平板導体を形成し、
前記導体板に前記各スリットの終端部を結ぶ線を折り曲げ線として、隣り合う前記導体部に交互に谷折り曲げと山折り曲げを行い、螺旋状に形成された前記平板導体コイルを形成する。 A method for manufacturing a flat conductor coil of an armature laminated core according to a second aspect of the present invention is a method of manufacturing a flat conductor coil in which a flat conductor is spirally wound around a magnetic pole portion of an armature laminated core. And
Slits extending from the one end in the width direction of the conductor plate and from the other end to the front side of the plate end on the other side are alternately provided at a predetermined pitch and in parallel, and each conductor portion formed by the slit is Forming a continuous plate conductor;
Using the line connecting the terminal portion of each slit to the conductor plate as a fold line, the adjacent conductor portions are alternately folded into a valley and a mountain, thereby forming the flat plate conductor coil formed in a spiral shape.

請求項１および２記載の電機子積層鉄心の平板導体コイルは、スリットによって形成される各導体部が連続した平板導体を螺旋状に形成しているので、従来のような、巻回のための組み立ておよび接続を行う必要がない。このため、磁極部への平板導体の装着を、多大な手間を削減して低コストで実施できる。
また、平板導体を構成する各導体部は連続しているので、従来のような平板導体片と平板導体接続片との位置ずれに起因する抵抗値の変化と相間絶縁不良が、元より生じない効果もあり、製品品質の向上が図れる。 Since the flat conductors of the armature laminated iron core according to claim 1 and 2 are formed by spirally forming a flat conductor in which each conductor portion formed by the slits is continuous, There is no need to assemble and connect. For this reason, the mounting of the flat conductor to the magnetic pole part can be carried out at a low cost by reducing a great deal of labor.
Moreover, since each conductor part which comprises a flat conductor is continuing, the change of resistance value and the interphase insulation defect resulting from position shift with a flat conductor piece and a flat conductor connection piece like the past do not arise originally. There is also an effect, and the product quality can be improved.

特に、請求項２記載の電機子積層鉄心の平板導体コイルは、螺旋状に巻かれた平板導体コイルを構成する導体部間に、別の螺旋状に巻かれた平板導体コイルを構成する導体部を入れ込み、平板導体コイルを多層に形成しているので、占積率をより高めることができる。 In particular, the flat conductor coil of the armature laminated iron core according to claim 2 has a conductor portion constituting another spirally wound flat conductor coil between conductor portions constituting the spirally wound flat conductor coil. Since the flat conductor coil is formed in multiple layers, the space factor can be further increased.

請求項３記載の電機子積層鉄心の平板導体コイルの製造方法は、スリットによって形成される導体部が連続した平板導体を形成し、この導体部を折り曲げて平板導体を螺旋状に形成するので、簡単な操作で、平板導体を連続した巻回状態に形成できる。このため、平板導体を磁極部に巻回して装着する際に、従来要していた多大の手間を削減でき、製造時における作業性が良好である。 In the method of manufacturing the flat conductor coil of the armature laminated iron core according to claim 3, the conductor formed by the slit forms a continuous flat conductor, and the conductive conductor is bent to form the flat conductor in a spiral shape. A flat conductor can be formed in a continuous winding state by a simple operation. For this reason, when winding a flat conductor around a magnetic pole part and mounting | wearing, the great effort conventionally required can be reduced, and workability | operativity at the time of manufacture is favorable.

続いて、添付した図面を参照しつつ、本発明を具体化した実施の形態につき説明し、本発明の理解に供する。
ここで、図１は本発明の一実施の形態に係る電機子積層鉄心の平板導体コイルの斜視図、図２は変形例に係る同電機子積層鉄心の平板導体コイルの斜視図、図３、図４は本発明の一実施の形態に係る電機子積層鉄心の平板導体コイルの製造方法の説明図である。 Next, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention.
Here, FIG. 1 is a perspective view of a flat conductor coil of an armature laminated core according to an embodiment of the present invention, FIG. 2 is a perspective view of a flat conductor coil of the armature laminated core according to a modification, FIG. FIG. 4 is an explanatory diagram of a method for manufacturing a flat conductor coil of an armature laminated core according to an embodiment of the present invention.

図１に示すように、本発明の一実施の形態に係る電機子積層鉄心の平板導体コイル（以下、単に平板導体コイルともいう）１０は、回転子または固定子を構成する電機子積層鉄心（図示しない）に使用するものであり、この電機子積層鉄心の磁極部に、平板導体１１（図３、図４参照）を螺旋状に巻回して装着するものである。以下、詳しく説明する。 As shown in FIG. 1, a flat conductor coil (hereinafter simply referred to as a flat conductor coil) 10 of an armature laminated core according to an embodiment of the present invention includes an armature laminated core ( The flat plate conductor 11 (see FIGS. 3 and 4) is spirally wound around and mounted on the magnetic pole portion of the armature laminated core. This will be described in detail below.

図１、図３に示すように、平板導体１１は、平面視して矩形状（長方形または正方形）となった例えば、厚さが０．５〜５ｍｍの導体板（例えば、銅板）の幅方向に沿って複数のスリット１２、１３が交互にかつ平行に設けられたものである。なお、導体板の大きさおよび厚みは、製造する電機子積層鉄心の大きさおよび形状によって決定される。
このスリット１２、１３のうち、一方側のスリット１２は、導体板の一端１４から他方側の板端、即ち、他端１５の手前位置に終端部１６が至るものであり、また、他方側のスリット１３は、導体板の他端１５から他方側の板端、即ち、一端１４の手前位置に終端部１７が至るものである。なお、本実施の形態では、導体板の一端１４から他端１５（他端１５から一端１４）の方向を幅方向（ｙ方向）とし、これに直交する方向を長手方向（ｘ方向）とする。 As shown in FIGS. 1 and 3, the flat conductor 11 has a rectangular shape (rectangular or square) in plan view, for example, a width direction of a conductor plate (for example, a copper plate) having a thickness of 0.5 to 5 mm. A plurality of slits 12 and 13 are provided alternately and in parallel. In addition, the magnitude | size and thickness of a conductor board are determined by the magnitude | size and shape of the armature laminated iron core to manufacture.
Of these slits 12 and 13, the slit 12 on one side extends from the one end 14 of the conductor plate to the plate end on the other side, that is, the front end of the other end 15. The slit 13 extends from the other end 15 of the conductor plate to the plate end on the other side, that is, a position before the one end 14, and the terminal end 17. In the present embodiment, the direction from the one end 14 to the other end 15 (the other end 15 to the one end 14) of the conductor plate is defined as the width direction (y direction), and the direction perpendicular thereto is defined as the longitudinal direction (x direction). .

このように、スリット１２とスリット１３は、導体板の長手方向に、所定ピッチで交互にかつ平行に繰り返し設けられ、平板導体１１がジグザグ状に形成されている。なお、各スリット１２、１３は、例えば、金型または切断機により形成でき、その幅（間隔）は、電機子積層鉄心に所望される特性と能力に応じて設定される。
また、スリット１２の終端部１６の先端位置と、スリット１３の終端部１７の先端位置は、それぞれ導体板の長手方向に渡って幅方向に同一位置となっている。ここで、各スリット１２、１３の終端部１６、１７は、各スリット１２、１３により形成される隣り合う導体部１８を、交互に谷折り曲げと山折り曲げをする際に、その先端が裂けないように、先端部を円弧状またはフィレット（曲線）状にしておけばよい。
また、前記各スリット１２、１３の終端部１６、１７の終端位置は、導体板の幅端に近づくに伴い、平板導体コイル１０における突出部（接続部）１９の突出量が低減するので、この終端部１６、１７の終端位置を、終端位置から板端までの長さが導体部１８の幅と同程度となる位置まで近づける。なお、図１においては、説明の便宜上、終端部１６、１７の終端位置から板端までの長さを、導体部１８の幅より広くしている。 As described above, the slits 12 and the slits 13 are repeatedly provided alternately and in parallel at a predetermined pitch in the longitudinal direction of the conductor plate, and the flat conductors 11 are formed in a zigzag shape. Each of the slits 12 and 13 can be formed by, for example, a mold or a cutting machine, and the width (interval) is set according to the characteristics and capability desired for the armature laminated core.
Further, the tip position of the end portion 16 of the slit 12 and the tip position of the end portion 17 of the slit 13 are the same position in the width direction over the longitudinal direction of the conductor plate. Here, when the end portions 16 and 17 of the slits 12 and 13 are alternately valley-folded and mountain-folded adjacent conductor portions 18 formed by the slits 12 and 13, the ends thereof are not torn. In addition, the tip may be arc-shaped or fillet (curved).
Further, since the end positions of the end portions 16 and 17 of the slits 12 and 13 approach the width end of the conductor plate, the protrusion amount of the protrusion portion (connection portion) 19 in the flat conductor coil 10 is reduced. The end positions of the end portions 16 and 17 are brought close to a position where the length from the end position to the plate end is approximately the same as the width of the conductor portion 18. In FIG. 1, for convenience of explanation, the length from the terminal position of the terminal portions 16, 17 to the plate end is made wider than the width of the conductor portion 18.

隣り合うスリット１２とスリット１３の間隔は、電機子積層鉄心の磁極の幅、長さ、または磁極の間隔に応じて定められる導体部１８の幅に応じて設定される。
また、形成するスリット１２、１３の本数は、磁極に巻回する平板導体の巻数に応じて設定されており、一端１４から形成するスリット１２の数、および他端１５から形成するスリット１３の数は、前記巻数に応じている。
これにより、複数のスリット１２、１３によって形成される複数の導体部１８が連続した平板導体１１を形成できる。 The interval between the adjacent slits 12 and the slits 13 is set according to the width and length of the magnetic poles of the armature laminated core or the width of the conductor portion 18 determined according to the interval between the magnetic poles.
The number of slits 12 and 13 to be formed is set according to the number of turns of the flat conductor wound around the magnetic pole. The number of slits 12 formed from one end 14 and the number of slits 13 formed from the other end 15 are set. Depends on the number of turns.
Thereby, the flat conductor 11 in which the plurality of conductor portions 18 formed by the plurality of slits 12 and 13 are continuous can be formed.

この平板導体１１は、図１、図４に示すように、導体板に、隣り合うスリット１２の終端部１６の終端位置を結ぶ線Ａ、および隣り合うスリット１３の終端部１７の終端位置を結ぶ線Ｂを折り曲げ線として、隣り合う導体部１８に、交互に異なる方向に折り曲げ加工がなされている。
ここで、折り曲げ加工とは、谷折り曲げと山折り曲げであり、一方側のスリット１２の終端部１６の終端位置を中心として、その両側に位置する導体部１８に、山折り曲げ（図４中の点線）と谷折り曲げ（図４中の一点鎖線）が、導体板の長手方向に交互に行われている。また、他方側のスリット１３の終端部１７の終端位置を中心として、その両側に位置する導体部１８にも、同様に谷折り曲げと山折り曲げが、平板導体１１の長手方向に交互に行われている。 As shown in FIGS. 1 and 4, the flat conductor 11 connects the conductor plate with a line A connecting the end positions of the end portions 16 of the adjacent slits 12 and the end positions of the end portions 17 of the adjacent slits 13. With the line B as a folding line, the adjacent conductor portions 18 are alternately bent in different directions.
Here, the bending process is a valley fold or a mountain fold, and the conductor portion 18 located on both sides of the end portion 16 of the slit 12 on one side is centered and bent (dotted line in FIG. 4). ) And valley folding (alternate long and short dashed lines in FIG. 4) are alternately performed in the longitudinal direction of the conductor plate. Further, with respect to the end position of the end portion 17 of the slit 13 on the other side, the conductor portions 18 located on both sides of the end portion 17 are similarly alternately bent and bent in the longitudinal direction of the flat conductor 11. Yes.

これにより、線Ａおよび線Ｂに谷折り曲げが行われた導体部１８の幅方向中央部に山折り曲げ（即ち、頂部）が、線Ａおよび線Ｂに山折り曲げが行われた導体部１８の幅方向中央部に谷折り曲げ（即ち、底部）が、それぞれ行われる。この曲げ位置は、導体板の長手方向に渡って幅方向に同一位置となっている。また、この曲げは、完全に折り曲げることなく、湾曲させる（円弧状にする）程度でよい。
以上に示した各曲げは、その折り曲げ位置が曲げ易くなるように、プレス機によりプレスしておくことが好ましい。
このように構成することで、平板導体１１の全体が螺旋状に形成され、平板導体コイル１０となる。 As a result, a fold-fold (that is, the top) is formed at the central portion in the width direction of the conductor portion 18 that is valley-folded in the lines A and B, and a width of the conductor portion 18 that is fold-folded in the lines A and B. A valley fold (that is, a bottom) is performed at the center in the direction. This bending position is the same position in the width direction over the longitudinal direction of the conductor plate. Further, this bending may be performed only by bending (arcing) without completely bending.
It is preferable to press each bending shown above with a press so that the bending position can be easily bent.
By configuring in this way, the entire flat conductor 11 is formed in a spiral shape to form the flat conductor coil 10.

この平板導体コイル１０は、図１に示すように、隣り合う導体部１８が間隔を有して配置された状態となっている。この平板導体１１の表面に、例えば絶縁材をつけ、絶縁処理を施することも可能である。このとき、平板導体１１の両側に配置される導体部１８の幅方向端部の側方のみ、絶縁処理を行わないようにする。
更に、図２に示すように、絶縁処理が施された平板導体コイル１０を構成する隣り合う導体部１８間に、この平板導体コイル１０と同一または類似の構成の別の平板導体コイル１０ａを構成する導体部１８を入れ込み、多層平板導体コイル２０を構成することもできる。 As shown in FIG. 1, the flat conductor coil 10 is in a state in which adjacent conductor portions 18 are arranged at intervals. For example, an insulating material may be attached to the surface of the flat conductor 11 to perform an insulation process. At this time, the insulation treatment is not performed only on the sides of the end portions in the width direction of the conductor portions 18 arranged on both sides of the flat conductor 11.
Further, as shown in FIG. 2, another flat conductor coil 10a having the same or similar configuration as that of the flat conductor coil 10 is formed between adjacent conductor portions 18 constituting the flat conductor coil 10 subjected to insulation treatment. The multilayered flat conductor coil 20 can also be configured by inserting the conductor portion 18 to be processed.

このように、平板導体コイル１０の隣り合う導体部１８間に、別の平板導体コイル１０ａの導体部１８を入れ込む場合は、平板導体コイル１０、１０ａの間隔と導体部１８の幅を適宜設定することにより、隣り合う導体部１８間に他方の導体部１８が入り込むようにする。
なお、本実施の形態では、平板導体コイル１０と別の平板導体コイル１０ａが、ともに絶縁処理されているが、別の平板導体コイル１０ａは絶縁処理が施されていないものでもよい。
これにより、多層平板導体コイル２０が製造される。
また、多層平板導体コイルは、磁極部に巻回して形成した平板導体コイルの外周に、平板導体コイルを更に巻回し形成したものでもよい。 Thus, when inserting the conductor part 18 of another flat conductor coil 10a between the adjacent conductor parts 18 of the flat conductor coil 10, the space | interval of the flat conductor coils 10 and 10a and the width | variety of the conductor part 18 are set suitably. By doing so, the other conductor part 18 enters between the adjacent conductor parts 18.
In the present embodiment, both the flat conductor coil 10 and another flat conductor coil 10a are insulated, but the other flat conductor coil 10a may not be insulated.
Thereby, the multilayer flat-plate conductor coil 20 is manufactured.
The multilayer flat conductor coil may be formed by further winding a flat conductor coil around the outer periphery of the flat conductor coil formed by winding the magnetic pole portion.

続いて、本発明の一実施の形態に係る電機子積層鉄心の平板導体コイルの製造方法について、図３、図４を参照しながら説明する。
まず、平面視して矩形状となった導体板（例えば、銅板）を準備する。
そして、例えば、金型または切断機により、図３に示すように、導体板の幅方向の一端１４から他端１５の手前位置に終端部１６が至るスリット１２と、他端１５から一端１４の手前位置に終端部１７が至るスリット１３を、交互に所定ピッチでかつ平行に繰り返して設ける。
次に、図４に示すように、導体板に各スリット１２、１３の終端部１６、１７をそれぞれ結ぶ線Ａ、Ｂを折り曲げ線として、隣り合う導体部１８に交互に谷折り曲げと山折り曲げを行う。
これにより、平板導体１１の全体が螺旋状に形成され、平板導体コイル１０となる。 Then, the manufacturing method of the flat conductor coil of the armature laminated core which concerns on one embodiment of this invention is demonstrated, referring FIG. 3, FIG.
First, a conductor plate (for example, a copper plate) having a rectangular shape in plan view is prepared.
Then, for example, as shown in FIG. 3, a slit 12 extending from the one end 14 in the width direction of the conductor plate to a position in front of the other end 15 by a mold or a cutter, The slits 13 that reach the end portion 17 to the front position are alternately provided at a predetermined pitch and in parallel.
Next, as shown in FIG. 4, the lines A and B connecting the terminal portions 16 and 17 of the slits 12 and 13 to the conductor plate are used as folding lines, and the adjacent conductor portions 18 are alternately folded into valleys and peaks. Do.
As a result, the entire flat conductor 11 is formed in a spiral shape to form the flat conductor coil 10.

そして、この平板導体コイル１０を、電機子積層鉄心の磁極部（例えば、インシュレータまたはコアの磁極）に装着する。
なお、平板導体コイル１０は、形成される挿入口２１が、磁極部の大きさに対応した形状となっている。
このため、平板導体コイルを、磁極部に装着するに際しては、例えば、磁極部が電機子積層鉄心から着脱できる構成となったもの、または磁極部の幅が基側から先側へかけて真っ直ぐまたは縮幅したものに取り付けることが好ましい。 And this flat conductor coil 10 is mounted | worn with the magnetic pole part (for example, magnetic pole of an insulator or a core) of an armature laminated iron core.
In the flat conductor coil 10, the formed insertion port 21 has a shape corresponding to the size of the magnetic pole part.
Therefore, when mounting the flat conductor coil to the magnetic pole part, for example, the magnetic pole part is configured to be removable from the armature laminated core, or the width of the magnetic pole part is straight from the base side to the front side or It is preferable to attach to a reduced width.

ここで、磁極部が電機子積層鉄心から着脱できる分割積層鉄心の場合、磁極部に平板導体コイルを装着した後、これを電機子積層鉄心に取り付け、必要に応じて、例えば、溶接または押圧により固定する。
また、磁極部の幅が基側から先側へかけて真っ直ぐまたは縮幅している場合、磁極部に平板導体コイルを装着した後、磁極部の先端部に極歯先端部を取り付け、必要に応じて、例えば、溶接または押圧により固定する。
これにより、電機子積層鉄心の磁極部に、平板導体コイルを組み立て手間を要することなく装着でき、併せて従来のような平板導体片と平板導体接続片との接続が不要で位置ずれを生じない電機子積層鉄心の平板導体コイルおよびその製造方法を提供できる。 Here, in the case of a split laminated iron core in which the magnetic pole part can be detached from the armature laminated iron core, after mounting the flat conductor coil on the magnetic pole part, this is attached to the armature laminated iron core, and if necessary, for example, by welding or pressing Fix it.
Also, if the width of the magnetic pole part is straight or reduced from the base side to the front side, after attaching the flat conductor coil to the magnetic pole part, attach the tip of the pole tooth to the tip part of the magnetic pole part. Accordingly, it is fixed by welding or pressing, for example.
