この発明は、回転電機の積層鉄心部材に関するものである。   The present invention relates to a laminated core member of a rotating electrical machine.

回転電機に用いられる鉄心のうち製造の合理化の工夫がなされた鉄心として特許文献１に記載の鉄心が挙げられる。
磁極ブロックが薄肉で直線状に連結されて構成されており、巻線のための空間が広く巻線工程で高速に巻線できる効果、整列して巻線できる効果、同時に複数の巻線処理ができる効果などが得られる。 Among the iron cores used in rotating electrical machines, an iron core described in Patent Document 1 is given as an iron core that has been devised for rationalization of manufacturing.
The magnetic pole block is thin and connected in a straight line, and the space for winding is wide, the effect of winding at high speed in the winding process, the effect of winding in alignment, and simultaneous multiple winding processing Effects that can be obtained.

特許第３３０７８８８号公報Japanese Patent No. 3307888

特許文献１に記載するような直線状のコアは、金型によるプレス加工で製造する。直線状に磁極ブロックを連結して並べた鉄心部材の単位でプレス打ち抜きして製造する。
薄板材料から打ち抜かれた鉄心部材は、それ自体に設けられた突起が嵌り合ってカシメられることで金型の中で積層され固定される。
金型の中で突起の加工、打ち抜き、積層、カシメが実施されるので高速に、自動化して、連続的な生産を実現でき、時間当たりの生産効率が高い。 A linear core as described in Patent Document 1 is manufactured by press working with a mold. Manufactured by press punching in units of iron core members arranged by connecting magnetic pole blocks in a straight line.
The iron core member punched out from the thin plate material is laminated and fixed in the mold by fitting and fitting the protrusions provided on itself.
Protrusion processing, punching, stacking, and caulking are performed in the mold, enabling high-speed, automated, continuous production, and high production efficiency per hour.

鉄心製造において、積層後の工程では、鉄心に絶縁物を装着する工程や巻線を施す工程があり、また、各工程間を自動搬送する場合がある。
これらの後工程においては、鉄心を把持する必要がある。
鉄心の把持には、鉄心の外形の形状を活用し、コアの形状に応じた特殊ツールでコアを把持し、その状態で絶縁物装着工程、巻線工程の処理を行う。 In the production of iron cores, in the process after lamination, there are a process of attaching an insulator to the iron core and a process of applying a winding, and there is a case where each process is automatically conveyed.
In these post processes, it is necessary to grip the iron core.
For gripping the iron core, the outer shape of the iron core is utilized, the core is gripped with a special tool corresponding to the shape of the core, and the insulator mounting process and the winding process are performed in that state.

また、一つのコアを処理した後は、処理済みのコアと未処理のコアを入れ替える必要がある。
この入れ替えには、コアのつかみ替えが必要である。
把持と位置決めの難易度はコアの形状、大きさに依存し、把持に時間を要すると、後工程のそれぞれで処理時間が増加し、時間当たりの生産効率を悪化させ製造コストが高くなる。
鉄心の把持、位置決めを容易化するために、鉄心自体に形成する形状としては、例えば突起、溝、穴等が挙げられる。
把持するためにのみ形成した把持部を設けると、製品が大型化したり、重量が増加したり、溝や穴などの欠落形状のために磁路面積が小さくなり磁束が減少する等の問題がある。 Moreover, after processing one core, it is necessary to replace the processed core and the unprocessed core.
This replacement requires changing the core.
The difficulty of gripping and positioning depends on the shape and size of the core, and if time is required for gripping, the processing time increases in each of the subsequent processes, and the production efficiency per hour is deteriorated and the manufacturing cost is increased.
In order to facilitate gripping and positioning of the iron core, examples of the shape formed on the iron core itself include protrusions, grooves, holes, and the like.
Providing a gripping part that is formed only for gripping causes problems such as an increase in product size, an increase in weight, and a decrease in magnetic path area due to missing shapes such as grooves and holes, resulting in a decrease in magnetic flux. .

この発明は、このような課題を解決するためになされたものであり、鉄心の位置決め、把持を容易化し、把持ツールを簡素化することにより鉄心部材の生産に要する費用と時間を低減できる回転電機の積層鉄心部材を提供することを目的とする。   The present invention has been made to solve such a problem, and facilitates the positioning and gripping of the iron core and simplifies the gripping tool to reduce the cost and time required for the production of the core member. An object of the present invention is to provide a laminated core member.

実施の形態１．
以下、この発明の実施の形態１に係る積層鉄心部材を図を用いて説明する。
図１は、積層鉄心部材１００の斜視図である。
図２は、図１の積層鉄心部材１００を構成する１枚の鉄心部材３０ａの右上端部の拡大図である。 Embodiment 1 FIG.
Hereinafter, the laminated core member according to the first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of the laminated core member 100.
FIG. 2 is an enlarged view of the upper right end portion of one core member 30a constituting the laminated core member 100 of FIG.

鉄心部材３０ａは、１枚の電磁鋼板から打ち抜き、又はエッチィングによって形成される。
また、１個のＴ型の磁極部材１１は、磁極ティース部１１ａとバックヨーク部１１ｂから構成され、９個の磁極部材１１のバックヨーク部１１ｂの端部同士を薄肉に残して結合した状態で連結磁極部材１２を構成する。
そして、複数の連結磁極部材１２を梯子状に並べて、それぞれの連結磁極部材１２の両端部が保持部１３に薄肉部１５で一体として接続されている。
磁極部材１１の磁極ティース部１１ａ側を前方としたとき、最後列の連結磁極部材１２の各バックヨーク部１１ｂの後方において、２つの保持部１３の端部同士が一体としてブリッジ部１４で接続されており、２個の保持部１３とブリッジ部１４でコ字形の枠体２０を構成し、更に枠体２０と、連結磁極部材１２で鉄心部材３０ａを構成する。 The iron core member 30a is formed by punching or etching from one electromagnetic steel sheet.
Further, one T-shaped magnetic pole member 11 is composed of a magnetic pole tooth portion 11a and a back yoke portion 11b, and the end portions of the back yoke portions 11b of the nine magnetic pole members 11 are joined in a thin state. The connecting magnetic pole member 12 is configured.
Then, a plurality of connecting magnetic pole members 12 are arranged in a ladder shape, and both end portions of each connecting magnetic pole member 12 are integrally connected to the holding portion 13 with a thin portion 15.
When the magnetic pole teeth portion 11a side of the magnetic pole member 11 is the front side, the ends of the two holding portions 13 are integrally connected by the bridge portion 14 behind the back yoke portions 11b of the last connected magnetic pole member 12. The two holding portions 13 and the bridge portion 14 constitute a U-shaped frame 20, and the frame 20 and the connecting magnetic pole member 12 constitute an iron core member 30 a.

積層鉄心部材１００は、上述の鉄心部材３０ａを複数枚数積層して構成される。
連結磁極部材１２を積層した部分が積層連結磁極部材４０であり、枠体２０を積層した部分が積層枠体５０となる。 The laminated core member 100 is configured by laminating a plurality of the above-described iron core members 30a.
The portion where the connecting magnetic pole member 12 is laminated is the laminated connecting magnetic pole member 40, and the portion where the frame body 20 is laminated becomes the laminated frame 50.

図３は、連結磁極部材１２と枠体２０の接続部の他の一例を示す図である。
図４は、プッシュバック工法を示す図である。
図１、図２では連結磁極部材１２と枠体２０は薄肉部１５で繋がっていた。
図３に示す鉄心部材３０ｂでは、プレス加工の過程で連結磁極部材１２の両端部を、枠体２０から刃６０で一旦打ち抜き、この部分を再度プッシュバック機構６１で枠体２０に嵌め戻すことによって連結磁極部材１２を枠体２０に固定する。 FIG. 3 is a view showing another example of the connecting portion between the connecting magnetic pole member 12 and the frame body 20.
FIG. 4 is a diagram showing a pushback method.
In FIG. 1 and FIG. 2, the connecting magnetic pole member 12 and the frame body 20 are connected by the thin portion 15.
In the iron core member 30 b shown in FIG. 3, both ends of the connecting magnetic pole member 12 are once punched from the frame body 20 with the blade 60 in the press working process, and this portion is fitted back to the frame body 20 by the pushback mechanism 61 again. The connecting magnetic pole member 12 is fixed to the frame body 20.

積層間の固定には、枠体２０自体に加工して設けた凹凸部を上下の鉄心部材間で嵌め合わせたカシメや、溶接、接着が用いられる。
製品となる積層連結磁極部材に直接カシメや溶接が用いられる場合、加工による歪みのために電磁鋼板の磁気特性が損なわれるが、枠体２０に固定部位を設け、積層連結磁極部材４０に積層間の固定部位を設けないことで積層連結磁極部材４０の磁気特性の劣化を防止することができる。 For fixing between the stacked layers, caulking, welding, and bonding in which concave and convex portions processed and provided on the frame body 20 are fitted between the upper and lower iron core members are used.
When caulking or welding is directly used for the laminated connecting magnetic pole member to be a product, the magnetic properties of the electromagnetic steel sheet are impaired due to distortion caused by processing. By not providing the fixed portion, it is possible to prevent the magnetic characteristics of the laminated connecting magnetic pole member 40 from deteriorating.

図５は、積層連結磁極部材４０の各磁極ティースに絶縁のための樹脂成型物６を装着した状態で電線７を巻線している状態を示す図である。
電線７はノズル８によって供給され、磁極ティースの周囲を周回して巻き付けられて電磁コイルを形成する。 FIG. 5 is a view showing a state in which the electric wire 7 is wound in a state where the resin molded product 6 for insulation is attached to each magnetic pole tooth of the laminated connecting magnetic pole member 40.
The electric wire 7 is supplied by the nozzle 8 and is wound around the magnetic pole teeth to form an electromagnetic coil.

図６は、巻線後に積層枠体５０を切断した状態を示す図である。
図７は、積層連結磁極部材４０と積層枠体５０を分離した図である。
図８は、積層枠体５０から分離した巻線後の積層連結磁極部材４０を環状に組み立てた固定子４１の斜視図である。 FIG. 6 is a diagram showing a state in which the laminated frame body 50 is cut after winding.
FIG. 7 is a view in which the laminated connecting magnetic pole member 40 and the laminated frame 50 are separated.
FIG. 8 is a perspective view of a stator 41 in which the laminated laminated magnetic pole member 40 separated from the laminated frame 50 is assembled in an annular shape.

積層連結磁極部材４０の一列の磁極ティースの全てに巻線を完了した後、図６に示すように積層枠体５０を一列分、積層枠体５０ごと切り離し、積層枠体５０付の積層連結磁極部材４０を取り出す。
次に図７に示すように、取り出した積層枠体５０付の積層連結磁極部材４０から積層枠体５０を分離し、積層連結磁極部材４０の薄肉部を折り曲げて組み立てると、図８に示す固定子４１となり、これに図示しない回転子を装着して回転電機を得る。 After the winding of all the magnetic pole teeth in one row of the laminated connecting magnetic pole member 40 is completed, as shown in FIG. The member 40 is taken out.
Next, as shown in FIG. 7, when the laminated frame body 50 is separated from the taken-out laminated coupling magnetic pole member 40 with the laminated frame body 50 and the thin portion of the laminated coupling magnetic pole member 40 is folded and assembled, the fixed state shown in FIG. A rotor 41 (not shown) is attached to the rotor 41 to obtain a rotating electrical machine.

この発明の実施の形態１に係る積層鉄心部材１００によれば、積層枠体５０の外壁や、積層枠体５０の内外壁間を自由に把持することができるので、製品となる積層連結磁極部材４０自体に把持部を設ける必要がなく、簡易なツールで容易に積層枠体５０に包含される積層連結磁極部材４０を間接的に固定することができる。
これにより、絶縁の処理、巻線の工程における、積層鉄心部材１００の位置決め、固定、搬送が容易になる。 According to the laminated core member 100 according to the first embodiment of the present invention, the outer wall of the laminated frame body 50 and the inner and outer walls of the laminated frame body 50 can be freely gripped. There is no need to provide a gripping portion on the 40 itself, and the laminated connecting magnetic pole member 40 included in the laminated frame 50 can be easily fixed with a simple tool.
This facilitates positioning, fixing, and conveyance of the laminated core member 100 in the insulation process and the winding process.

例えば、絶縁工程においては、各磁極ティースに樹脂成型物６を装着する際に、積層枠体５０を把持しておけば、磁極ティースの周囲の空間に樹脂成型物６を装着するツールが干渉しないので作業が容易になる。
また、巻線工程でも積層枠体５０を把持するので、把持のための作業空間を十分に確保でき、確実に積層連結磁極部材４０を固定して巻線できる。
また、製品自体に把持部を設ける必要がないので製品の外形を大型化したり重量が増加する等の問題もない。 For example, in the insulation process, when the resin molded product 6 is mounted on each magnetic pole tooth, if the laminated frame 50 is held, the tool for mounting the resin molded product 6 does not interfere with the space around the magnetic pole tooth. So work becomes easy.
Further, since the laminated frame body 50 is gripped even in the winding process, a working space for gripping can be sufficiently secured, and the laminated connecting magnetic pole member 40 can be securely fixed and wound.
In addition, since it is not necessary to provide a gripping part on the product itself, there is no problem of increasing the outer shape of the product or increasing the weight.

また、積層間の固定部位は、積層枠体５０を構成する枠体２０に設ければ良いので、製品となる磁極部材１１の表面にはカシメ用の凹凸を設けたり、接着を施す必要がない。これにより、磁気特性に優れた固定子を得ることができる。
なお、積層枠体５０から積層連結磁極部材４０を分離後も、樹脂成型物６や樹脂成型物６の代用とし得る電着塗装、及び巻線により積層固定状態は確保される。 Further, since the fixing portion between the layers may be provided on the frame body 20 constituting the laminated frame body 50, it is not necessary to provide caulking unevenness or adhesion on the surface of the magnetic pole member 11 as a product. . Thereby, the stator excellent in magnetic characteristics can be obtained.
Even after the laminated connecting magnetic pole member 40 is separated from the laminated frame 50, the laminated fixed state is secured by the electrodeposition coating that can be used in place of the resin molded product 6 or the resin molded product 6 and the windings.

また、複数の連結磁極部材１２を一つの枠体２０とともに形成することで、製造工数を大幅に削減でき、製造コストを安価にできる。   Further, by forming the plurality of connecting magnetic pole members 12 together with one frame 20, the number of manufacturing steps can be greatly reduced, and the manufacturing cost can be reduced.

なお、本実施の形態では、保持部１３の端部同士をブリッジ部１４で接続して枠体２０を構成したが、ブリッジ部１４無しでも構わない。
また、プッシュバックによって鉄心部材３０ｂを製造する場合は、ブリッジ部１４を両端の保持部１３間に複数、梯子状に設けても良い。 In the present embodiment, the frame 20 is configured by connecting the ends of the holding portion 13 with the bridge portion 14, but the bridge portion 14 may be omitted.
Moreover, when manufacturing the iron core member 30b by pushback, a plurality of bridge portions 14 may be provided between the holding portions 13 at both ends in a ladder shape.

なお、本実施の形態では、絶縁工程として樹脂成型物６を装着する例を示したが、積層鉄心部材１００全体を電着塗装しても良い。   In the present embodiment, an example in which the resin molded product 6 is mounted as an insulating process is shown. However, the entire laminated core member 100 may be electrodeposited.

図１０に示す位置決め構造は、切り欠き２２である。
実施の形態１のような積層枠体５０があれば、その形状自体を利用して把持することも可能であるが、本実施の形態に示す丸穴２１や切り欠き２２のような簡素な構造を枠体２２０に追加するだけで、更に容易に、確実に積層枠体の把持、搬送をすることができる。 The positioning structure shown in FIG. 10 is a notch 22.
If there is the laminated frame 50 as in the first embodiment, it can be gripped using its shape itself, but a simple structure such as the round hole 21 and the notch 22 shown in the present embodiment. By simply adding to the frame 220, the laminated frame can be gripped and transported more easily and reliably.

なお、位置決め構造は、穴や、切り欠きの他、突起でも良い。
また、穴や突起の形状は、当該形状を利用して積層鉄心部材を搬送し、固定できるものであればどのような構造でも良い。 Note that the positioning structure may be a hole, a notch, or a protrusion.
Further, the shape of the hole or the protrusion may be any structure as long as the laminated core member can be transported and fixed using the shape.

実施の形態３．
以下、この発明の実施の形態３に係る積層鉄心部材について実施の形態２と異なる部分を中心に説明する。
図１１は、鉄心部材３３０の要部拡大図である。
枠体３２０の一部に四角形状の穴２３を設けており、枠体３２０は、穴２３の縁である薄肉リンク部２４で繋がっている。
鉄心部材３３０を積層すると、この薄肉リンク部２４もそのまま積層される。
薄肉リンク部２４の切断は、薄肉リンク部２４を設けていない場所の切断に比べて格段に容易である。
これにより、簡易な切断機構で積層枠体の切断が可能となり、最終製品の製造工数、製造コストを低減できる。 Embodiment 3 FIG.
Hereinafter, the laminated core member according to the third embodiment of the present invention will be described with a focus on differences from the second embodiment.
FIG. 11 is an enlarged view of a main part of the iron core member 330.
A rectangular hole 23 is provided in a part of the frame 320, and the frame 320 is connected by a thin link portion 24 that is an edge of the hole 23.
When the core member 330 is laminated, the thin link portion 24 is also laminated as it is.
Cutting the thin link portion 24 is much easier than cutting at a place where the thin link portion 24 is not provided.
Thereby, the laminated frame body can be cut with a simple cutting mechanism, and the manufacturing man-hour and manufacturing cost of the final product can be reduced.

実施の形態４．
以下、本発明の実施の形態４に係る積層鉄心部材について、実施の形態１〜実施の形態３と異なる部分を中心に説明する。
図１２は、鉄心部材４３０の要部拡大図である。
この実施の形態では、実施の形態２で述べた位置決め構造と、実施の形態３で述べた薄肉リンク部とを兼ね備えた構造を採用している。
即ち、位置決め構造である丸穴４２１を、連結磁極部材１２が薄肉部１５を介して枠体４２０に接続される部分の中間部分に設け、更に丸穴４２１の縁と、枠体４２０の内壁面及び外壁面の間に薄肉リンク部４２４が形成されるように丸穴４２１の大きさを調整している。 Embodiment 4 FIG.
Hereinafter, the laminated core member according to the fourth embodiment of the present invention will be described with a focus on differences from the first to third embodiments.
FIG. 12 is an enlarged view of a main part of the iron core member 430.
In this embodiment, a structure having both the positioning structure described in the second embodiment and the thin link section described in the third embodiment is employed.
That is, a round hole 421 that is a positioning structure is provided in an intermediate portion of the portion where the connecting magnetic pole member 12 is connected to the frame body 420 via the thin portion 15, and the edge of the round hole 421 and the inner wall surface of the frame body 420 are provided. The size of the round hole 421 is adjusted so that the thin link portion 424 is formed between the outer wall surfaces.

このように丸穴４２１を形成することにより、積層鉄心部材を搬送する際や、磁極ティースに巻線を施す際は丸穴４２１に棒状の搬送具兼固定具を挿入して積層枠体ごと、積層鉄心部材を搬送又は固定し、積層連結磁極部材を積層枠体から分離するときは、積層枠体の当該丸穴４２１の部分を切断することにより容易に積層枠体付きの積層連結磁極部材を分離できる。   By forming the round hole 421 in this way, when transporting the laminated iron core member or when winding the magnetic pole teeth, a rod-like transporter / fixture is inserted into the round hole 421 and the entire laminated frame body. When the laminated core member is conveyed or fixed and the laminated linking magnetic pole member is separated from the laminated frame body, the laminated linking magnetic pole member with the laminated frame body can be easily removed by cutting the portion of the round hole 421 of the laminated frame body. Can be separated.

図１３は、位置決め、薄肉リンク兼用構造の他の一例を示す平面図である。深い切り欠き４２２を枠体４２０に設けることにより、位置決め構造と薄肉リンク部を兼ねることができる。
なお、位置決め、搬送用の構造と、薄肉リンク部を兼ねることができる構造であれば、どのような構造でも良い。 FIG. 13 is a plan view showing another example of the positioning and thin-wall link combined structure. By providing the deep cutout 422 in the frame body 420, it is possible to serve as a positioning structure and a thin link portion.
It should be noted that any structure may be used as long as the structure for positioning and conveyance can also serve as the thin link portion.

この実施の形態に係る積層鉄心部材によれば、位置決め構造と薄肉リンク部を一箇所にまとめて形成できるので、積層鉄心部材の製造工数を削減でき、製造コストを削減することができる。   According to the laminated core member according to this embodiment, since the positioning structure and the thin link portion can be formed together in one place, the number of manufacturing steps of the laminated core member can be reduced, and the manufacturing cost can be reduced.

実施の形態５．
以下、この発明の実施の形態５に係る積層鉄心部材５００について実施の形態３と異なる部分を中心に説明する。
図１４は、この発明の実施の形態５に係る鉄心部材５３０の要部拡大図である。
図１５は、鉄心部材５３０を積層した積層鉄心部材５００の斜視図である。
鉄心部材５３０は、連結磁極部材１２と連結磁極部材５１２という大きさの異なる２種類の連結磁極部材を包含する。
そして、枠体５２０に設けた位置決め用の丸穴２１及び薄肉リンク部２４の位置も、連結磁極部材１２，５１２の接続位置に合わせて調整している。
すなわち、位置決め用の丸穴２１間の間隔（ピッチ）も、薄肉リンク部２４の配置も、鉄心部材５３０が包含する連結磁極部材の構成によって変動することになる。 Embodiment 5 FIG.
Hereinafter, the laminated core member 500 according to the fifth embodiment of the present invention will be described focusing on the differences from the third embodiment.
FIG. 14 is an enlarged view of a main part of an iron core member 530 according to Embodiment 5 of the present invention.
FIG. 15 is a perspective view of a laminated core member 500 in which iron core members 530 are laminated.
The iron core member 530 includes two types of connecting magnetic pole members having different sizes such as the connecting magnetic pole member 12 and the connecting magnetic pole member 512.
The positions of the positioning round holes 21 and the thin link portions 24 provided in the frame 520 are also adjusted in accordance with the connection positions of the connecting magnetic pole members 12 and 512.
That is, the interval (pitch) between the positioning round holes 21 and the arrangement of the thin link portions 24 vary depending on the configuration of the connecting magnetic pole member included in the iron core member 530.

このような鉄心部材５３０を複数枚数積層した積層鉄心部材５００に対する後工程においては、どのような種類の積層連結磁極部材が、どのような位置に配置されているかを把握する必要がある。   In a subsequent process for the laminated core member 500 in which a plurality of such iron core members 530 are laminated, it is necessary to grasp what kind of laminated connecting magnetic pole member is located at what position.

図１５の積層枠体５５０には、この積層鉄心部材が包含する積層連結磁極部材４０の位置と種類等を示す識別子９が貼付又は刻印されている。
この識別子９は、図示しない巻線機の識別子読取手段で読み取られて、巻線工程におけるノズルの動作制御、積層鉄心部材５００の搬送、積層枠体５５０の分離位置の決定等に利用される。
例えば、図１５に示す積層鉄心部材５００に表示されている識別子９は、図１５手前を前方として、９個の積層磁極部材を連結した積層連結磁極部材５４０ａと６個の積層磁極部材を連結した積層連結磁極部材５４０ｂが、前から１列−３列−１列−３列−１列の順に並んでいることを表す。
また、識別子９には、位置決め構造、薄肉リンク部の配置データ、積層鉄心部材５００の積層枚数を含んでも良い。 An identifier 9 indicating the position and type of the laminated connecting magnetic pole member 40 included in the laminated core member is affixed or stamped on the laminated frame 550 of FIG.
The identifier 9 is read by an identifier reading unit of a winding machine (not shown), and is used for nozzle operation control in the winding process, conveyance of the laminated core member 500, determination of the separation position of the laminated frame 550, and the like.
For example, the identifier 9 displayed on the laminated core member 500 shown in FIG. 15 is connected to the laminated connecting magnetic pole member 540a connecting nine laminated magnetic pole members and the six laminated magnetic pole members with the front of FIG. 15 as the front. It represents that the lamination | stacking connection magnetic pole member 540b is located in a line from the front in the order of 1 row-3 row-1 row-3 row-1 row.
Further, the identifier 9 may include the positioning structure, the arrangement data of the thin link portion, and the number of laminated core members 500.

この実施の形態に係る積層鉄心部材５００によれば、積層枠体５５０に包含される積層連結磁極部材の種類と配置、位置決め構造、薄肉リンク部の配置等の情報を示す識別子９を利用して、後工程への搬送、絶縁処理を自動化でき、積層枠体５５０毎に巻線機を自動制御できるので、大幅に製品の製造工程を自動化し、製造コストを削減できる。   According to the laminated core member 500 according to this embodiment, the identifier 9 indicating information such as the type and arrangement of the laminated connecting magnetic pole members included in the laminated frame body 550, the positioning structure, and the arrangement of the thin link portion is used. In addition, since it is possible to automate the conveyance to the subsequent process and the insulation process and to automatically control the winding machine for each laminated frame 550, the manufacturing process of the product can be greatly automated and the manufacturing cost can be reduced.

また、１つの積層鉄心部材に複数種類の積層連結磁極部材を包含でき、小ロット製品を１つの金型に少数だけ混在させて生産することも可能なので、金型の製造コストを削減できる。
また、これによって安価、且つ短納期に製品を供給できる。 In addition, a plurality of types of laminated connecting magnetic pole members can be included in one laminated iron core member, and a small number of products can be mixed and produced in one mold, so that the manufacturing cost of the mold can be reduced.
In addition, the product can be supplied at a low cost and with a short delivery time.

また、単一製品の製造を繰り返す場合に必要な、各種機器の設定やツールの入れ替えが発生しないので、製品の製造に要する全体としての時間を短縮でき、時間当たりの生産性を高めることができる。   In addition, since there is no need to set up various devices or replace tools, which is necessary when repeating the manufacture of a single product, the overall time required to manufacture the product can be shortened and the productivity per hour can be increased. .

また、大小の積層連結磁極部材が混在しても、搬送ピッチを大きさに合わせて自動調整できるので、電磁鋼板を無駄なく利用できる。   Moreover, even if large and small laminated connecting magnetic pole members are mixed, the conveyance pitch can be automatically adjusted according to the size, so that the electromagnetic steel sheet can be used without waste.

また、鉄心部材５３０の積層枚数を識別子９のデータとして含むことにより、より幅広い製品に対応できる。
なお、鉄心部材５３０の積層枚数が同一の積層鉄心部材５００のみを製造する場合は、鉄心部材５３０の枠体５２０にのみ識別子９を貼付等しても良い。 Further, by including the number of laminated core members 530 as the data of the identifier 9, a wider range of products can be handled.
When only the laminated core member 500 having the same number of laminated iron core members 530 is manufactured, the identifier 9 may be attached only to the frame body 520 of the iron core member 530.
