【考案の詳細な説明】
本考案はリニアパルスモータ−の可動子の構造に関する
。[Detailed Description of the Invention] The present invention relates to the structure of a mover of a linear pulse motor.
従来のパルスモータ−の可動子は第１図に示す如く、可
動子体１と突極部２が一体の部品であった。As shown in FIG. 1, the movable element of a conventional pulse motor has a movable element body 1 and a salient pole part 2 that are an integral part.
リニアパルスモータ・−は可動子の直線的な定量間欠運
動を利用し、近年、種々の製品の位置決メ用アクチェー
ターとして活用されているが、この位置決ノ機能をより
高精度化するためには複数の突極部２間の間隔をきわめ
て高精度に加工する必要がある。Linear pulse motors utilize linear, fixed-quantity intermittent motion of a movable element, and have recently been used as positioning actuators for various products, but in order to make this positioning function even more precise. It is necessary to process the spacing between the plurality of salient pole parts 2 with extremely high precision.
従来構造では可動子体１に突極２を直接形成する以外に
手段がなく、ＮＣ工作機械等による高価な加工を必要と
した。In the conventional structure, there is no other way than to directly form the salient poles 2 on the movable body 1, which requires expensive processing using an NC machine tool or the like.
又加工後ＶＣＶＢ気焼鈍を行なわなければならず、熱変
形による寸法の狂いのため位置決ノ精度の向上にも限界
があるなど、低コストで高精度のリニアパルスモータ−
が得られないという欠点があった。In addition, VCVB air annealing must be performed after processing, and there is a limit to the improvement of positioning accuracy due to dimensional deviations due to thermal deformation.
The disadvantage was that it was not possible to obtain
本考案はかかる欠点を除去したもので、その目的は突極

テップモーターを供給することにある。The present invention eliminates such drawbacks, and its purpose is to create a structure in which the salient pole part 2 is separate from the movable member body 1, and each salient pole part is a flat integral part. Our objective is to provide a linear step motor that facilitates part machining and enables inexpensive and highly accurate positioning.
以下実施例に基づいて本考案を詳しく説明する。The present invention will be described in detail below based on examples.
第２図は、本考案の一実施例を示す図であり２１は可動
子であり、複数の突極８が所定の間隔で形成され、それ
ぞれ励磁コイル３が巻かれている。FIG. 2 is a diagram showing an embodiment of the present invention. Reference numeral 21 denotes a movable element, in which a plurality of salient poles 8 are formed at predetermined intervals, and an excitation coil 3 is wound around each of them.
それぞれの突甑８の先端部には補助アーム部Ｔによって
一体に連結された磁性体からなる突極プレート６が固着
されている。A salient pole plate 6 made of a magnetic material and integrally connected by an auxiliary arm part T is fixed to the tip of each of the protrusions 8.
第３図は本考案による突極プレートの一例を示す平面図
であり、図に示すように、それぞれの突極プレート６は
、補助アーム部ｌを介して連結された状態で一体に成形
されろ。FIG. 3 is a plan view showing an example of the salient pole plate according to the present invention. As shown in the figure, each of the salient pole plates 6 is integrally formed with the salient pole plates 6 connected via the auxiliary arm portion l. .
したがって、それぞれの突極プレート６０間隔は、補助
アーム部γによって、加工中の寸法変化もなく、きわめ
て高い精度が得られる。Therefore, due to the auxiliary arm portion γ, the spacing between the salient pole plates 60 does not change in dimension during processing, and extremely high precision can be obtained.
また、突極プレートは１枚の薄い板から、プレス加工、
エツチング加工等により成形することができるので、き
わめて安価に作ることができ、かつ加工精度も高精度の
ものが容易にできる。In addition, the salient pole plate is made from a single thin plate, press-processed,
Since it can be formed by etching or the like, it can be manufactured at a very low cost and can be manufactured with high precision.
第２図において、励磁コ、１ル３に通電すると、発生し
た磁束は、第４図に示すように、補助アーム部γを通る
■−［Ｆ］−〇−ｏの経路と、固定子４と固定子の突極
５を通って主磁気回路を形成する■−■−〇−０の２つ
の経路を通って磁気ループを作る。In Fig. 2, when the excitation coil 1 is energized, the generated magnetic flux passes through the auxiliary arm part γ and the stator 4 through the path ■-[F]-〇-o. A magnetic loop is created through two paths: ■-■-〇-0, which passes through the salient poles 5 of the stator and forms the main magnetic circuit.
しかし補助アーム部１の断匣積を充分小さくしておけば
、［株］−〇−〇−００経路を通る磁束は、補助アーム
部１で飽和してしまい、はとんどの磁束は■−■−〇−
ｏの経路を通る。However, if the shear volume of the auxiliary arm section 1 is made sufficiently small, the magnetic flux passing through the -〇-〇-00 path will be saturated at the auxiliary arm section 1, and most of the magnetic flux will be - ■−〇−
Take route o.
したがって、従来のリニアモーターと同様、可動子１は
スライド機構１１によって固定子４上を移動する。Therefore, like the conventional linear motor, the movable element 1 is moved on the stator 4 by the slide mechanism 11.
以上述べた如く、本考案は、可動子の突極先端部に、安
価で高精度の加工が可能な＠性体からなるｍプレートを
固着するので、可動子の突極間の間隔は、突極プレート
の間隔によって決められるため、可動子の加工にはそれ
ほど高い精度が要求されず、低コスト化が可能となる。As described above, in the present invention, an m-plate made of a ferrous body, which can be processed at low cost and with high precision, is fixed to the tip of the salient poles of the mover, so the spacing between the salient poles of the mover is Since it is determined by the spacing between the pole plates, the machining of the mover does not require very high precision, making it possible to reduce costs.
したがって、従来に比べて安価で高精度のリニアパルス
モータ−が実現できるという、きわめてすぐれた効果を
有するものである。Therefore, the present invention has an extremely superior effect in that it is possible to realize a linear pulse motor that is cheaper and more accurate than the conventional one.
