る円筒の継鉄部とで構成する電動機の製造方法に関する
。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method of manufacturing an electric motor in which a stator core is composed of a star-shaped toothed portion and a cylindrical yoke portion surrounding the toothed portion.
「従来の技術」
固定子鉄心を外径方向へ放射状に形成される、すなわち
星型の歯部とこれを囲繞するリング状の継鉄部とで形成
する電動機の製造方法は、歯部と継鉄部とを嵌合する結
果大きな公差を生じたり、嵌合が困難になるといった打
法きを行うと回転子が歯部の内径との間で接触すること
になる。``Prior art'' A method of manufacturing an electric motor in which a stator core is formed radially in the outer diameter direction, that is, a star-shaped tooth portion and a ring-shaped yoke portion surrounding the tooth portion, is If the fitting method with the iron part produces a large tolerance or makes fitting difficult, the rotor will come into contact with the inner diameter of the tooth part.
この様な危険を回避するため、回転子と歯部との空隙を
大きく形成すると空隙の磁束に大きな抵抗が発生して運
転効率が低下するといった問題になった。In order to avoid such a danger, if the gap between the rotor and the teeth is made large, a large resistance is generated in the magnetic flux in the gap, resulting in a problem that the operating efficiency is reduced.
そこで、この回転子と歯部の内径との間に形成される空
隙を正確に得ることが製造上の大きな問題点であり、こ
の問題点が解決されることによって運転効率の高い電動
機を得ることができた。Therefore, it is a major manufacturing problem to accurately obtain the air gap formed between the rotor and the inner diameter of the teeth, and by solving this problem, it is possible to obtain an electric motor with high operating efficiency. was completed.
従来の電動機は、歯部が内径側に開口してスロットを形
成するものであり、この様な問題を発生することはなく
、通常０．１〜０．２ａｍ程度の空隙を容易に確保でき
た。Conventional electric motors have teeth that open toward the inner diameter to form slots, so these problems do not occur and it is usually possible to easily secure a gap of about 0.1 to 0.2 am. .
しかしながら、歯部が継鉄部から分離され、巻線後に結
合されることになると、プレス型による公差があり、組
立後に大きな公差を生じることがある。However, when the teeth are separated from the yoke and combined after winding, there are tolerances due to the press die, which may result in large tolerances after assembly.
「発明が解決しようとする問題点」
従って、継鉄部がリング状に形成されるとその円が正確
に形成されることによって歯部が打法きおよび嵌合の公
差によって生じる寸法誤差の結果が回転子との隣接部分
となる歯部内径が正確に円形にならないことになる。``Problem to be Solved by the Invention'' Therefore, when the yoke is formed into a ring shape, the circle is formed accurately, and the teeth are the result of dimensional errors caused by the tolerance of the hammering method and fitting. However, the inner diameter of the tooth portion adjacent to the rotor will not be accurately circular.
このため、回転子との空隙を予め大きく設定する必要が
あり、効率の良い電動機を構成することが困難であった
。For this reason, it is necessary to set a large air gap with the rotor in advance, making it difficult to construct an efficient electric motor.
本発明は、この様な事情に鑑みてなされたものであり、
公差が少なく運転効率が良くなる電動機を得るための電
動機の製造方法を提供することを目的としている。The present invention was made in view of these circumstances, and
It is an object of the present invention to provide a method for manufacturing an electric motor to obtain an electric motor with small tolerances and high operating efficiency.
［問題点を解決するための手段］
本発明は、歯部の端部を継鉄部の内径側に衝合すると共
にアリとアリミゾによって嵌合するよう構成し、この嵌
合前に歯部に巻線を装着し、かつ固定子鉄心の外径側お
よび内径側を同時に支持する成形型に装着し、この成形
型で樹脂成形したことによって問題点を解決している。[Means for Solving the Problems] The present invention is configured such that the ends of the teeth abut against the inner diameter side of the yoke and are fitted by dovetails and grooves, and before this fitting, the teeth are The problem was solved by mounting the windings on a mold that simultaneously supports the outer diameter side and the inner diameter side of the stator core, and molding the stator core with resin using this mold.
「作用」
歯部の端部と継鉄部の内径側とを衝合させて両者をアリ
とアリミゾとで嵌合すると、継鉄部に対して歯部が正確
にその内径を形成することができる。"Function" When the end of the teeth and the inner diameter side of the yoke are brought into contact and the two are fitted with dovetails and dovetails, the teeth can accurately form the inner diameter of the yoke. can.
継鉄部は、リング状に形成されると径方向に変形が少な
く、プレスおよび組み立てによって大きな公差を生じる
ことはなく、内径側の公差が少なく形成できる。When the yoke is formed into a ring shape, it is less deformed in the radial direction, does not produce large tolerances due to pressing and assembly, and can be formed with small tolerances on the inner diameter side.
従って、継鉄部によって歯部の内径が少ない公差で形成
できるため、樹脂でフレームを形成する場合、その成形
型によって継鉄部の外径側を基準にすることができる。Therefore, since the inner diameter of the tooth part can be formed with small tolerances by the yoke, when the frame is formed from resin, the outer diameter side of the yoke can be used as a reference depending on the molding die.
