【発明の属する技術分野】
本発明は固定子鉄芯を複数に分割して巻線を直巻巻装した後、分割鉄芯体を環状に一体化する構成とした内転型電動機の固定子に関する。
【０００２】
【従来の技術】
近年、複数に分割した分割鉄芯体に巻線を施工し分割鉄芯体を環状に配列してなる固定子とそれを製造する方法が普及されている。
【０００３】
従来、この種の固定子の構成の一例として特開平９ー４６９７９号公報に記載されたものが知られていた。以下、その構成について図１２〜図１６を参照しながら説明する。
【０００４】
図１２および図１３に示すように、分割された歯部２０１に絶縁材料２０２、２０３で絶縁処理し、巻線２０４の巻始め部と巻終わり部となる中継ピン２０５を設けて巻線２０４を巻装したのち、これらを環状に合体して固定子を構成していた。
【０００５】
また、図１４〜図１６に示すように、同様にスロット３０１の数が４個の固定子鉄芯を、隣接する歯部３０２相互を連結する継鉄部３０３の中間部分で前記スロットの数と同数に分割し、絶縁材料３０４を介して巻線３０５を巻線機３０７により巻装するが、継鉄部３０３が歯部３０２に対して周方向に延設され円弧状に長いため、巻線３０５の巻装作業においては特殊な巻線案内ガイドを装着するなどの対策を必要としていた。
【０００６】
【発明が解決しようとする課題】
このような従来の固定子の構成では、前者の構成をそのまま後者に適用し分割された分割鉄芯体３０６の歯部３０２に巻線３０５を巻装するとき、継鉄部３０３が円弧状に長いため巻線案内ガイドａ３０８および巻線案内ガイドｂ３０９を装着するなどの対策が必要であり、巻線３０５が巻線案内ガイドａ３０８および巻線案内ガイドｂ３０９の表面を摺動しつつ歯部３０２に巻装されるために巻線品質の確保が困難であり、また歯部３０２と継鉄部３０３の一部が一体の分割構造であるため鉄芯材料としての電磁鋼板の圧延方向の限定による電動機効率の向上も困難であるという課題があった。
【０００７】
本発明は上記課題を解決するもので、固定子鉄芯に対し特殊な巻線案内ガイドを装着しないで巻線の巻装が可能であり、歯部または継鉄部の分割構造や形状を改善し電磁鋼板の圧延方向を限定することにより電動機効率を向上することのできる内転型電動機の固定子を提供することを目的とする。

【０００９】
本発明によれば、特殊な巻線案内ガイドなどを装着することなく巻線巻装ができ巻線品質を確保でき、また電動機効率を向上することのできる内転型電動機の固定子を提供することができる。
【００１０】
【発明の実施の形態】
本発明の請求項１に記載の発明は、歯部と継鉄部とを一体に形成する４個の分割鉄芯体ａ、及び前記分割鉄芯体ａに挟持される継鉄部を形成する４個の分割鉄芯体ｂによって固定子鉄芯を構成し、
巻線巻装時は、それぞれの前記分割鉄芯体ａとそれぞれの前記分割鉄芯体ｂとを分割した状態で、それぞれの前記分割鉄芯体ａに絶縁材料を装着し、前記絶縁材料の装着後、Ａ相巻線またはＢ相巻線を直巻巻装することで、前記分割鉄芯体ａを各々２個のＡ相巻線巻装体と２個のＢ相巻線巻装体とし、
巻線巻装完了後、Ａ相巻線巻装体を構成する前記分割鉄芯体ａとＢ相巻線巻装体を構成する前記分割鉄芯体ａとの間に前記分割鉄芯体ｂを配置して環状に一体化することで、４個のスロットと４個の歯部で構成される固定子鉄芯を構成する内転型電動機の固定子であって、

【００１５】
また、４個の分割鉄芯体ｂ３の外径側がハウジング１４の内径部に対して非接触であるため、前記分割鉄芯体ｂ３の外周部形状を高精度に製作する必要が無く、低価格の金型を使用することもでき、コスト合理化が可能となる。

【００２０】
また、４個の分割鉄芯体ｂ３として圧延方向の磁気特性が極めて良好な方向性電磁鋼板を使用することにより、継鉄部における磁気特性を極めて良好に保ち、電動機効率を大幅に改善することが可能となる。

Two of the B-phase winding wound bodies 9 in which the B-equipped windings 8 are wound at positions separated from each other are alternately arranged in an annular shape by sandwiching the divided iron cores b3 divided by the yoke portion 10 A stator 11 is formed. And the said divided iron core b3 is set as the structure laminated | punched and laminated | stacked so that the circumferential direction, ie, a longitudinal direction, may become a rolling direction in an electromagnetic steel plate manufacturing process. At the time of winding, the stator iron core 1 is divided into eight pieces, the insulating material 12 is attached to the four divided iron core bodies a2, and then the A-phase winding 6 or the B-phase winding 8 is attached. Directly wound by a winding machine (not shown) to form two A-phase winding winding bodies 7 and two B-phase winding winding bodies 9 respectively, and after winding winding is completed, an insulating material The outer peripheral side 12a of 12 is pressed and deformed in the inner diameter direction so as to be integrated along the inner peripheral side of the divided iron core body b3 to form four slots 13 and to constitute an annular stator.
[0013]
Further, only the arc-shaped portion on the outer diameter side of the four divided iron cores a2 is fitted and held to the inner diameter portion of the housing 14, and contributes to ensuring the roundness of the stator inner diameter, thereby providing four divided iron cores. The outer diameter side of the body b3 is configured such that a gap 15 is formed in a non-contact manner on the inner diameter portion of the housing 14.

When winding, the divided iron core body b3 is removed, the winding is wound around the single divided iron core body a2, and a complicated winding guide guide or the like is installed in the winding machine with a simple structure. Since it can be wound with a winding motion, the winding can be wound without sliding on the surface of the winding guide, preventing defects such as damage to the winding film or disconnection and ensuring winding quality.

Since the four divided iron cores b are punched and laminated so that the longitudinal direction is the rolling direction of the electromagnetic steel sheet manufacturing process, the A-phase winding or the B-phase winding is wound directly. Can be wound without a complicated winding guide guide, preventing damage to the winding film or disconnection, and improving the motor efficiency It is possible to provide a stator of the motive.

Further, only the arc-shaped portions on the outer diameter side of the four divided iron cores a are fitted and held with respect to the inner diameter portion of the housing, contributing to ensuring the roundness of the stator inner diameter, and the four divided iron cores b. Since the outer diameter side of the housing is configured so as not to be in contact with the inner diameter portion of the housing, it is not necessary to manufacture the outer peripheral shape of the divided iron core body b3 with high accuracy, and a low-cost mold may be used. And cost rationalization is possible.

Moreover, since the directional electromagnetic steel sheet is used for the four divided iron cores b, the motor efficiency can be greatly improved.
[0026]
In addition, since the radial direction of the four divided iron cores a coincides with the rolling direction of the electromagnetic steel sheet, and the directional electromagnetic steel sheet is also used for the divided iron core a, the motor efficiency can be further improved. it can.
