Description

この発明は、リニアモータ用積層鉄心の構造及びその製造方法に係り、特に、積層鉄心の材料歩留まりと特性の改善に関するものである。 The present invention relates to a structure of a laminated core for a linear motor and a manufacturing method thereof, and more particularly to improvement of material yield and characteristics of the laminated core.

リニアモータは、駆動コイルを巻回した磁極ティースを複数個連設してなる可動子と、この可動子と所定の空隙を介して対設され進行方向に互いに異なる極性の永久磁石を配列してなる固定子とからなり、上記駆動コイルを励磁することにより、発生する進行磁界によって可動子に推力を与え、この推力によって可動子に搭載された被搬送物を搬送するものである。上記可動子は所定のピッチでスロットが形成された櫛歯状の磁性鉄板を複数枚積層して形成されるが、その製造に際しては、駆動コイルの組み込みの関係上、磁極ティースごとに分割して構成するもの（例えば、特許文献１参照）や、各磁極ティースの少なくとも一対の縁部同士を屈曲可能に連結する連結手段を設けたもの（例えば、特許文献２参照）等がある。 A linear motor is composed of a mover comprising a plurality of magnetic teeth wound around a drive coil, and permanent magnets arranged opposite to each other in a traveling direction and arranged opposite to the mover through a predetermined gap. When the drive coil is excited, a thrust is applied to the mover by the generated magnetic field, and the object to be transported mounted on the mover is transported by this thrust. The mover is formed by laminating a plurality of comb-shaped magnetic iron plates each having a slot formed at a predetermined pitch. In manufacturing, the mover is divided for each magnetic pole tooth for the purpose of incorporating a drive coil. There are a configuration (for example, see Patent Document 1), a configuration in which connecting means for connecting at least a pair of edges of each magnetic pole tooth so as to be bendable (for example, see Patent Document 2), and the like.

特開２０００−２１７３３４号（請求項１、図１等）JP 2000-217334 A (Claim 1, FIG. 1, etc.) 特許第３４２８４８６号（請求項１、図７等）Japanese Patent No. 3428486 (Claim 1, FIG. 7, etc.)

一般に、上記積層鉄心を構成する磁極ティースは、その形状がバックヨーク部とこのバックヨーク部から突出したティース部とからなっており、これらを一枚の磁性鋼板からプレス打ち抜きにより製造される。また、プレス打ち抜きは２枚１組で打ち抜かれる。即ち、２枚の抜き板は、１つ目の抜き板のティース部間に２つ目の抜き板のティース部が位置するように、互いに逆向きに、かつ、ピッチをずらして打ち抜かれる。 In general, the magnetic teeth forming the laminated iron core have a back yoke part and a tooth part protruding from the back yoke part, and these are manufactured by press punching from a single magnetic steel sheet. In addition, press punching is performed by one set of two sheets. That is, the two punched plates are punched in the opposite directions and at a different pitch so that the tooth portion of the second punched plate is positioned between the tooth portions of the first punched plate.

ところが、トルク脈動を低減しトルク性能を向上させるために、ティース部の先端の幅寸法を大きくした（スロット開口幅を小さくした）場合に、１つ目の抜き板のティース部間に２つ目の抜き板のティース部を配置することができなくなり、材料歩留まりが低下するという問題がある。逆に言うと、１つ目の抜き板のティース部間に２つ目の抜き板のティース部を配置するために、ティース部の先端の幅寸法が制限され、トルク特性の改善を妨げていた。 However, in order to reduce torque pulsation and improve torque performance, when the width of the tip of the tooth portion is increased (the slot opening width is reduced), the second between the teeth portions of the first punch plate Therefore, there is a problem that the tooth portion of the blank plate cannot be arranged and the material yield is lowered. Conversely, since the tooth portion of the second punching plate is disposed between the tooth portions of the first punching plate, the width of the tip of the tooth portion is limited, which hinders improvement of torque characteristics. .

この発明は、上記のような問題点を解決するためになされたものであり、ティース部の先端の幅寸法を大きくした場合でも、リニアモータの特性を低下させることなく、比較的簡単な手法により、材料歩留まりの向上ならびにトルク性能の改善を図ったリニアモータの積層鉄心およびリニアモータ用積層鉄心の製造方法を得るようにしたものである。 The present invention has been made to solve the above-described problems, and even when the width of the tip of the tooth portion is increased, the linear motor characteristics are not deteriorated by a relatively simple method. A linear motor laminated iron core and a linear motor laminated iron core manufacturing method for improving the material yield and the torque performance are obtained.

この発明に係るリニアモータの積層鉄心は、バックヨーク部とこのバックヨーク部から突出したティース部とからなる磁極ティースコア片を、互いに隣接するティース部が略平行になるように複数個直線状に並べて構成され、各ティース部は、中間部に設けられたティース主部と、バックヨーク部側端部に設けられ上記ティース主部よりも幅寸法が小さい縮幅部と、先端部に設けられ上記ティース主部よりも幅寸法が大きい拡幅部とからなり、且つ、上記互いに隣接する縮幅部間の距離が拡幅部の幅寸法よりも大きくなるように構成されており、上記縮幅部は、上記ティース部の幅方向両側に一対の磁極切欠部を設けることにより形成されており、上記磁極切欠部には、磁性材料からなる磁極係合部材を埋め込むようにしたことを特徴とするものである。 The laminated core of the linear motor according to the present invention includes a plurality of magnetic pole teascore pieces each including a back yoke portion and a tooth portion protruding from the back yoke portion so that the adjacent tooth portions are substantially parallel to each other. Each teeth portion is arranged side by side, the teeth main portion provided at the intermediate portion, the reduced width portion provided at the back yoke portion side end portion having a smaller width dimension than the teeth main portion, and the tip portion provided above consists of a widened portion is larger width than the tooth main unit, and, the distance between adjacent reduced width portion is configured to the size Kunar so than the width dimension of the widened part of each other, the reduced width portion are formed by providing a pair of magnetic pole notch on both sides in the width direction of the teeth, the above-mentioned magnetic pole notch, characterized in that so as to fill the pole engaging member made of a magnetic material Than is.

また、この発明に係るリニアモータの積層鉄心の製造方法は、バックヨーク部とこのバックヨーク部から突出したティース部とからなる磁極ティースコア片を互いに隣接するティース部が略平行になるように複数個直線状に並べて構成し、且つ前記磁極ティースコア片を、上記隣接するティース部間に形成される空間に他の同形状のティース部が配置されるよう反対向きに他の磁極ティースコア片を複数個直線状に並べた状態で打ち抜き加工するものにおいて、各ティース部は、中間部に設けられたティース主部と、バックヨーク部側端部に設けられ上記ティース主部よりも幅寸法が小さい縮幅部と、先端部に設けられ上記ティース主部よりも幅寸法が大きい拡幅部とからなり、且つ、上記互いに隣接する縮幅部間の距離が拡幅部の幅寸法よりも大きくなるように構成されており、上記縮幅部は、上記ティース部の幅方向両側に一対の磁極切欠部を設けることにより形成されており、上記磁極切欠部には鉄心組立後に磁性材料からなる磁性係合部材を埋め込むようにしたことを特徴とするものである。 Further, in the method for manufacturing a laminated core of a linear motor according to the present invention, a plurality of magnetic pole teascore pieces including a back yoke portion and a teeth portion protruding from the back yoke portion are arranged so that adjacent tooth portions are substantially parallel to each other. The magnetic pole tee score pieces are arranged side by side in a straight line , and the other magnetic pole tee score pieces are arranged in the opposite direction so that other teeth portions of the same shape are arranged in the space formed between the adjacent tooth portions. In the punching process in a state where a plurality of lines are arranged in a straight line , each tooth portion has a smaller width than the tooth main portion provided at the intermediate portion and the end portion on the side of the back yoke portion. It is composed of a reduced width portion and a widened portion which is provided at the tip and has a width dimension larger than that of the main tooth portion, and the distance between the adjacent reduced width portions is the width dimension of the widened portion. The reduced width portion is formed by providing a pair of magnetic pole notches on both sides of the teeth portion in the width direction. The magnetic pole notches are made of a magnetic material after assembling the iron core. The magnetic engaging member to be embedded is embedded .

本発明に係るリニアモータの積層鉄心およびその製造方法においては、ティース部のバックヨーク部側端部に縮幅部が設けられており、磁極ティースコア片を直線状に並べた状態では、隣接する縮幅部間の距離が拡幅部の幅寸法よりも大きいので、ティース部に拡幅部を設けた場合でも、複数の磁極ティースコア片を直線状に並べてなるコア部材をプレス加工する際に、ティース部間に他のコア部材のティース部を配置した状態で２個のコア部材を打ち抜くことができ、高トルク性能を有する積層鉄心を材料歩留まり及び生産性を向上させながら実現できる効果がある。 In the laminated core of the linear motor and the method for manufacturing the same according to the present invention, the back yoke portion side end portion of the teeth portion is provided with a reduced width portion, and adjacent in a state where the magnetic pole tea score pieces are arranged in a straight line. Since the distance between the reduced width portions is larger than the width dimension of the widened portion, even when the widened portion is provided in the teeth portion, when the core member formed by arranging a plurality of magnetic pole tea score pieces in a straight line is pressed, the teeth The two core members can be punched in a state where the tooth portions of other core members are arranged between the portions, and there is an effect that a laminated core having high torque performance can be realized while improving the material yield and productivity.

実施の形態１．
図１は本発明の実施の形態１の実施の対象となるリニアモータの運転状態を示す概略構成図である。
図１に示すように、リニアモータ１は、固定子２と可動子３により構成される。固定子２は、モータ駆動方向（図中、両向き矢印の方向）に延在する板状の固定子鉄心２１と、固定子鉄心２１上にモータ駆動方向に沿って所定の間隔で配置され交互に極性が異なる複数の永久磁石２２、２３とから構成されている。Embodiment 1 FIG.
FIG. 1 is a schematic configuration diagram showing an operation state of a linear motor that is an object of implementation of the first embodiment of the present invention.
As shown in FIG. 1, the linear motor 1 includes a stator 2 and a mover 3. Stator 2 is arranged in a plate-like stator core 21 extending in the motor drive direction (the direction of the double-headed arrow in the figure) and alternately arranged on the stator core 21 at predetermined intervals along the motor drive direction. And a plurality of permanent magnets 22 and 23 having different polarities.

一方、可動子３は、上記固定子２の永久磁石２２、２３と所定の間隔を介して配置され、モータ駆動方向に沿って順次連設された複数の磁極ティースコア片３０と、各磁極ティースコア片３０にインシュレータ３２を介して巻回された駆動コイル３３とから構成されている。各磁極ティースコア片３０は、バックヨーク部１２と、バックヨーク部１２から固定子２側に突出したティース部１３とを有する形状とし、これを紙面方法に複数個積層してなる分割積層鉄心を、複数個（図では６個）互いのバックヨーク部１２を当接しながら、例えば接着等で直線状に連結されて磁極連設体３０を構成されている。 On the other hand, the mover 3 is arranged at a predetermined interval from the permanent magnets 22 and 23 of the stator 2 and is provided with a plurality of magnetic pole tee score pieces 30 successively arranged along the motor driving direction, and each magnetic pole tee. A driving coil 33 is wound around the score piece 30 via an insulator 32. Each magnetic pole tee score piece 30 has a shape having a back yoke portion 12 and a teeth portion 13 protruding from the back yoke portion 12 to the stator 2 side, and a divided laminated iron core formed by laminating a plurality of them in a paper surface method. A plurality (six in the figure) of the back yoke portions 12 are in contact with each other while being linearly connected, for example, by bonding or the like, so that the magnetic pole connecting body 30 is configured.

図２は図１に示すコア部材のプレス加工状態を示す平面図であり、図３は図２の要部拡大図である。図２に示すように、２つの磁極ティースコア片３０、３１が互いに反対方向から嵌め合いした配置が採用されている。磁極ティースコア片３０、３１は例えば磁性鋼板で構成され、プレス加工して製造されるが、一方の磁極ティースコア片３０のティース部１３a間に他方のコア部材３１のティース部１３ｂが位置するように配置された状態でプレス加工される。すなわち、一方の磁極ティースコア片３０のティース部１３aが略平行となるように複数個直線状に並べられた状態で、上記隣接するティース部１３a間に形成される空間に、他方の磁極ティースコア片３１のティース部１３ｂが配置されるようにして、プレス機（図示していない）により打ち抜きされる。上記ティース部１３aとティース部１３ｂは同形状である。 FIG. 2 is a plan view showing a pressed state of the core member shown in FIG. 1, and FIG. 3 is an enlarged view of a main part of FIG. As shown in FIG. 2, the arrangement | positioning which the two magnetic pole tea score pieces 30 and 31 fitted from the mutually opposite direction is employ | adopted. The magnetic pole tee score pieces 30 and 31 are made of, for example, a magnetic steel plate and are manufactured by pressing, so that the tooth portion 13b of the other core member 31 is positioned between the tooth portions 13a of the one magnetic pole tee score piece 30. Is pressed in a state of being arranged in That is, in a state where a plurality of teeth 13a of one magnetic pole tee score piece 30 are arranged in a straight line so as to be substantially parallel, the other magnetic pole tee score is formed in a space formed between the adjacent teeth 13a. It is punched out by a press (not shown) so that the teeth 13b of the piece 31 are arranged. The teeth part 13a and the teeth part 13b have the same shape.

図３から明らかなように、ティース部１３の根元部（バックヨーク部１２側端部）の幅方向両側には、一対の台形の磁極切欠部１３eが設けられ、これにより、ティース部１３の根元部には、縮幅部１３ｆが形成されている。ティース部１３の先端部には鉄心のトルク特性を高めるための拡幅部１３ｄが設けられており、ティース部１３の中間部、即ち上記縮幅部１３ｆと拡幅部１３ｄとの間には、ティース主部１３ｇが形成されている。従って、ティース部１３の縮幅部１３ｆの幅寸法は、ティース主部１３ｇの幅寸法よりも小さく、ティース主部１３ｇの幅寸法は拡幅部１３ｄの幅寸法より小さい。   As is clear from FIG. 3, a pair of trapezoidal magnetic pole notches 13 e are provided on both sides in the width direction of the root portion (end portion on the back yoke portion 12) of the tooth portion 13. The portion is formed with a reduced width portion 13f. A widened portion 13d for enhancing the torque characteristics of the iron core is provided at the tip of the tooth portion 13, and the middle portion of the tooth portion 13, that is, between the reduced width portion 13f and the widened portion 13d, A portion 13g is formed. Accordingly, the width dimension of the reduced width portion 13f of the tooth portion 13 is smaller than the width dimension of the tooth main portion 13g, and the width dimension of the tooth main portion 13g is smaller than the width dimension of the widened portion 13d.

すなわち、図２に戻り、一方の磁極ティースコア片３０の互いに隣接するティース部１３aの縮幅部１３ｆ間には、他方の磁極ティースコア片３１の磁極ティース部１３bの拡幅部１３ｄが位置している。このため、コア片１３を直線状に並べた状態で、拡幅部１３ｄの幅寸法をＢｔ、隣接する縮幅部１３ｆ間の距離をＢｓとした場合、Ｂｓ＞Ｂｔとなっている。なお、プレス金型の刃物の損傷等を抑制するためには、磁極ティースコア片３１（磁性鋼板）の板厚をＴとした場合、Ｂｓ≧（Ｂｔ＋２Ｔ）と設定することが好ましい。 That is, returning to FIG. 2, the widened portion 13d of the magnetic pole teeth portion 13b of the other magnetic pole tee score piece 31 is located between the reduced width portions 13f of the adjacent tooth portions 13a of the one magnetic pole tee score piece 30. Yes. For this reason, Bs> Bt, where Bt is the width dimension of the widened portion 13d and Bs is the distance between adjacent reduced width portions 13f with the core pieces 13 arranged in a straight line. In order to suppress damage to the blade of the press die, it is preferable to set Bs ≧ (Bt + 2T), where T is the thickness of the magnetic pole tea score piece 31 (magnetic steel plate).

各バックヨーク部１２のティース部１３が突出している側から、一対の台形の磁極係合部材１５が上記磁極ティースコア片のプレス加工と同時あるいは別個の工程で薄肉連結部１６を残すように打ち抜かれる。その際、上記薄肉連結部１６はティース部１３との間で寸法Ｂ(図３参照)だけ連結されており、磁極係合部材１５は、その薄肉連結部１６を介してバックヨーク部１３からティース部側に回動可能に連結されている。上記寸法Ｂは薄肉連結部１６を矢印の方向に回動しても折れて分離することのないような大きさに設定されている。従って、図４は磁極係合部材１５の利用方法を示す状態図であり、図４（a）の状態から磁極係合部材１５をティース部１３側へさらに回動させることにより図４(b)に示すように、磁極係合部材１５は磁極切欠部１３eである縮幅部１３fに係合（嵌合）する。   A pair of trapezoidal magnetic pole engaging members 15 are punched from the side where the teeth 13 of each back yoke 12 protrude from the side so as to leave the thin connecting portion 16 at the same time as the magnetic pole tee score piece pressing or in a separate process. It is. At that time, the thin connecting portion 16 is connected to the tooth portion 13 by a dimension B (see FIG. 3), and the magnetic pole engaging member 15 is connected to the teeth from the back yoke portion 13 via the thin connecting portion 16. It is connected to the part side so that rotation is possible. The dimension B is set to a size that does not break and separate even if the thin connecting portion 16 is rotated in the direction of the arrow. Therefore, FIG. 4 is a state diagram showing a method of using the magnetic pole engaging member 15, and when the magnetic pole engaging member 15 is further rotated from the state of FIG. As shown, the magnetic pole engaging member 15 is engaged (fitted) with the reduced width portion 13f which is the magnetic pole notch portion 13e.

すなわち、ティース部１３に駆動コイル３３を巻回する際には、磁極係合部材１５は縮幅部１３fに係合され、ティース部１３の外周に設けられたインシュレータ３２によって縮幅部１３f内に保持される。
このような積層鉄心５では、磁極ティース部１３の先端部に拡幅部１３ｄが設けられているので、トルク脈動を低減しトルク性能を向上させることができる。また、ティース部１３の根元部に縮幅部１３ｆが設けられているので、ティース部１３に拡幅部１３ｄを設けても、磁極ティースコア片３０、３１をプレス加工する際に、磁極ティースコア片３０のティース部１３a間に他のコア片３１の磁極ティース部１３ｂを配置した状態で２個のコア片３１を打ち抜くことができ、材料歩留まり及び生産性を向上させることができる。That is, when the drive coil 33 is wound around the tooth portion 13, the magnetic pole engaging member 15 is engaged with the reduced width portion 13 f and is inserted into the reduced width portion 13 f by the insulator 32 provided on the outer periphery of the tooth portion 13. Retained.
In such a laminated iron core 5, since the widened portion 13d is provided at the tip of the magnetic pole tooth portion 13, torque pulsation can be reduced and torque performance can be improved. Further, since the reduced width portion 13f is provided at the root portion of the tooth portion 13, even when the widened portion 13d is provided in the teeth portion 13, when the magnetic pole tea score pieces 30, 31 are pressed, the magnetic pole tea score piece. The two core pieces 31 can be punched in a state where the magnetic pole tooth portions 13b of the other core pieces 31 are arranged between the 30 tooth portions 13a, and the material yield and productivity can be improved.

また、組立後には磁極係合部材１５により磁極切欠部１３eが埋められているので、磁極切欠部１３eによる磁路が狭くなる影響を低減し、トルクの低下を抑制することができ、良好な性能を得ることができる。
さらに、磁極係合部材１５がインシュレータ３２によって保持されるので、部品点数を増やすことなく磁極係合部材１５を保持することができる。
さらにまた、プレス加工後には、磁極係合部材１５が薄肉連結部１６によってバックヨーク部１２に回動可能に連結されているので、磁極係合部材１５を磁極ティースコア片３０、３１と一体に扱うことができ、組立の際の搬送性に優れている。In addition, since the magnetic pole notch 13e is filled with the magnetic pole engaging member 15 after assembly, the influence of the magnetic path narrowed by the magnetic pole notch 13e can be reduced, and a reduction in torque can be suppressed. Can be obtained.
Furthermore, since the magnetic pole engaging member 15 is held by the insulator 32, the magnetic pole engaging member 15 can be held without increasing the number of parts.
