以下、その電動機の構成について図16を参照しながら説明する。   Hereinafter, the configuration of the electric motor will be described with reference to FIG.

図に示すように、鋼板を積層してなる鋼板製のコア構成体(積層鉄芯体、以下同)301と磁性粉体と絶縁部材との複合材料で形成された粉体性のコア構成体(圧粉磁心、以下同)302とを接合して構成され、前記積層鉄芯体301の積層方向の両端部は対にして設けた圧粉磁心302により挟持され、各々が接合された構成のコア(固定子鉄芯、以下同)であった。   As shown in the figure, a powdery core structure formed of a composite material of a steel sheet core structure (laminated iron core body, hereinafter the same) 301 formed by laminating steel sheets, a magnetic powder, and an insulating member.

When constituted by powder, the size of each part, for example, the width K of the tooth part, is generally larger than when constituted by laminated electromagnetic steel sheets (when the axial dimensions are the same).

上記構成において、主に歯部3を形成し巻線を装着または巻装する分割鉄芯体A4を、電磁鋼板を打抜き・積層して形成したため、その一部または全部を磁性粉末で構成した場合に比較し、磁路断面積が少なくてすむ。したがって前記歯部3に装着または巻装するA相巻線8またはB相巻線9の周長は短縮されることになり、巻線の抵抗値が減少することで巻線で消費される損失が低減する。さらに分割鉄芯体B6の回転子軸方向長さを分割鉄芯体A4の回転子軸方向長さより長く構成することで磁路断面積を増加し総磁束数を増加でき電動機効率が向上する。また、分割鉄芯体A4は、歯部3がその外周部端部まで同一形状(幅、厚み)であるため、絶縁ボビン7に巻装された巻線の装着および分割鉄芯体A4に装着した絶縁ボビン7に対する直接巻線が可能となる。   In the above configuration, when the divided iron core A4 that mainly forms the tooth portion 3 and mounts or winds the winding is formed by punching and laminating electromagnetic steel sheets, a part or all thereof is made of magnetic powder Compared to, the cross-sectional area of the magnetic path is small. Therefore, the peripheral length of the A-phase winding 8 or the B-phase winding 9 attached or wound on the tooth portion 3 is shortened, and the loss consumed in the winding due to the decrease in the resistance value of the winding. Is reduced. Further, by configuring the length of the divided iron core B6 in the rotor axial direction to be longer than the length of the divided iron core A4 in the rotor axial direction, the magnetic path cross-sectional area can be increased, the total number of magnetic fluxes can be increased, and the motor efficiency is improved. In addition, since the divided iron core A4 has the same shape (width and thickness) up to the outer peripheral end portion of the tooth portion 3, it is mounted on the winding wound around the insulating bobbin 7 and mounted on the divided iron core A4. The direct winding with respect to the insulated bobbin 7 is possible.

また、圧入嵌合だけで分割鉄芯体A4と分割鉄芯体B6の合体、組立ができる。   Moreover, the division | segmentation iron core body A4 and division | segmentation iron core body B6 can be united and assembled only by press fitting.

また、図8においては、絶縁ボビン7に巻装された巻線の装着および分割鉄芯体A4に装着した絶縁ボビン7に対する直接巻線が可能で、磁性粉末で構成した分割鉄芯体B6の成型用金型の小型化が可能となる。また、図9においては、分割鉄芯体A4に装着した絶縁ボビン7に巻線を巻装する際、継鉄部5の内径部分の一部を一体に形成したことで絶縁ボビン7の変形が防止され、巻線巻装の作業性が向上する。   Further, in FIG. 8, the winding wound around the insulating bobbin 7 and the direct winding with respect to the insulating bobbin 7 attached to the divided iron core A4 are possible, and the divided iron core B6 made of magnetic powder is formed. The molding die can be downsized. In FIG. 9, when winding the winding around the insulating bobbin 7 attached to the divided iron core A4, the insulating bobbin 7 is deformed by integrally forming a part of the inner diameter portion of the yoke portion 5. This prevents the winding workability from being improved.

なお、本実施の形態において、固定子鉄芯のスロット数は4個としたが、いくつでもよく、また、各相巻線と固定子鉄芯2との絶縁は主に絶縁ボビンによったが、絶縁フィルムおよび粉体を使用することも可能である。   In the present embodiment, the number of slots of the stator iron core is four, but any number may be used, and the insulation between each phase winding and the stator iron core 2 is mainly based on an insulating bobbin. It is also possible to use insulating films and powders.

また、継鉄部5あるいは分割鉄芯体B6は、以下のように周方向に分割して形成してもよい。   Further, the yoke part 5 or the divided iron core B6 may be formed by being divided in the circumferential direction as follows.

図7は電磁鋼板を打抜き・積層した分割鉄芯体A4を、その外周部で磁路を形成する継鉄部5を一体に形成した形状とし、その他の継鉄部5を磁性粉末を所定の形状に成型した圧粉磁心で形成し、相隣接する分割鉄芯体A4相互を連結するために4個に分割した分割鉄芯体B6を配置した構成で、分割鉄芯体A4の継鉄部5の周方向端部に設けた凸部A12と前記分割鉄芯体B6の周方向端部に設けた凹部B15と組合されて一体化されてなる。   FIG. 7 shows a split iron core A4 obtained by punching and stacking magnetic steel sheets into a shape integrally formed with a yoke portion 5 that forms a magnetic path at the outer periphery thereof, and the other yoke portion 5 is made of a predetermined magnetic powder. The yoke part of the divided iron core body A4 is configured by arranging the divided iron core body B6 divided into four parts in order to connect the adjacent divided iron core bodies A4 to each other, formed by the powder magnetic core molded into a shape. 5 is combined and integrated with a convex portion A12 provided at the circumferential end of 5 and a concave portion B15 provided at the circumferential end of the divided iron core B6.

また、図8は電磁鋼板を打抜き・積層した分割鉄芯体A4を、その外周部で磁路を形成する継鉄部5に突出し、外周部端部に設けた凹部A11に対し、4個に分割した分割鉄芯体B6の周方向端部に設けた凸部B14と組合わされて一体化されてなる。   Further, FIG. 8 shows that the divided iron core A4 obtained by punching and laminating electromagnetic steel sheets protrudes into the yoke portion 5 that forms the magnetic path at the outer peripheral portion thereof, and is divided into four in the concave portion A11 provided at the outer peripheral end portion. The divided iron core body B6 is combined and integrated with a convex portion B14 provided at the end in the circumferential direction.

また、図9は電磁鋼板を打抜き・積層した分割鉄芯体A4を、その外周部で磁路を形成する継鉄部5の内径部分の一部を一体に形成した構成としたものである。   FIG. 9 shows a structure in which a divided iron core A4 obtained by punching and laminating electromagnetic steel sheets is integrally formed with a part of the inner diameter portion of the yoke portion 5 forming a magnetic path at the outer peripheral portion thereof.

(実施の形態2)
図10〜図13において、実施の形態1と異なるところは、磁性粉末を所定の形状に成型した圧粉磁心で形成した分割鉄芯体B6を回転子軸に対し直角方向に2分割し、各々分割鉄芯体Ba6a、Bb6bとし、この分割鉄芯体Ba6a、Bb6bの内周上を4分する位置に取付部19を設け、この取付部19に前記分割鉄芯体A4の外周部分を配置し、前記分割鉄芯体Ba6a、Bb6bにより挟み込む形で合体した構成とした点である。また、図1から図9と同じ構成要素については同じ符号を用いその説明を省略する。
(Embodiment 2)
10 to 13, the difference from the first embodiment is that a divided iron core body B6 formed of a powder magnetic core obtained by molding magnetic powder into a predetermined shape is divided into two in a direction perpendicular to the rotor axis, The divided iron cores Ba6a and Bb6b are provided, and a mounting portion 19 is provided at a position that divides the inner circumference of the divided iron core bodies Ba6a and Bb6b into four, and the outer peripheral portion of the divided iron core body A4 is disposed on the mounting portion 19. This is a configuration in which the divided iron cores Ba6a and Bb6b are combined in a sandwiched manner. Moreover, the same components as those in FIGS. 1 to 9 are denoted by the same reference numerals and the description thereof is omitted.

上記構成において、主に歯部3を形成し巻線を装着または巻装する分割鉄芯体A4を、電磁鋼板を打抜き・積層して形成したため、その一部または全部を磁性粉末で構成した場合に比較し、磁路断面積が少なくてすむ。したがって前記歯部3に装着または巻装するA相巻線8またはB相巻線9の周長は短縮されることになり、巻線の抵抗値が減少することで巻線で消費される損失が低減する。さらに分割鉄芯体B6の回転子軸方向長さを分割鉄芯体A4の回転子軸方向長さより長く構成することで磁路断面積を増加し総磁束数を増加でき電動機効率が向上する。また、分割鉄芯体A4は、歯部3がその外周部端部まで同一形状(幅、厚み)であるため、絶縁ボビン7に巻装された巻線の装着および分割鉄芯体A4に装着した絶縁ボビン7に対する直接巻線が可能となる。また、分割鉄芯体Ba6a、Bb6bの内周部を4分する位置に設けた取付部19に対し分割鉄芯体Aを配置するため、分割鉄芯体Aの周方向の位置決めが精度よく確実にかつ容易に固定装着ができることとなる。   In the above configuration, when the divided iron core A4 that mainly forms the tooth portion 3 and mounts or winds the winding is formed by punching and laminating electromagnetic steel sheets, a part or all thereof is made of magnetic powder Compared to, the cross-sectional area of the magnetic path is small. Therefore, the peripheral length of the A-phase winding 8 or the B-phase winding 9 attached or wound on the tooth portion 3 is shortened, and the loss consumed in the winding due to the decrease in the resistance value of the winding. Is reduced. Further, by configuring the length of the divided iron core B6 in the rotor axial direction to be longer than the length of the divided iron core A4 in the rotor axial direction, the magnetic path cross-sectional area can be increased, the total number of magnetic fluxes can be increased, and the motor efficiency is improved. In addition, since the divided iron core A4 has the same shape (width and thickness) up to the outer peripheral end portion of the tooth portion 3, it is mounted on the winding wound around the insulating bobbin 7 and mounted on the divided iron core A4. The direct winding with respect to the insulated bobbin 7 is possible. Further, since the divided iron core body A is disposed with respect to the mounting portion 19 provided at a position that divides the inner peripheral portion of the divided iron core bodies Ba6a and Bb6b into four, the circumferential positioning of the divided iron core body A is ensured with high accuracy. In addition, the fixed mounting can be easily performed.

また、分割鉄芯体B6を軸方向1/2の位置で上下2分割して分割鉄芯体Ba6a、Bb6bとしたとき、非分割のものに比較して成型金型の小型化ができ、金型費用の削減が可能である。   Further, when the divided iron core body B6 is divided into two parts at the upper and lower positions in the axial direction to form the divided iron core bodies Ba6a and Bb6b, the molding die can be downsized as compared with the non-divided one. Mold cost can be reduced.

また、分割鉄芯体A4の固定は、圧入嵌合に加えて分割鉄芯体Ba6a、Bb6bによる上下方向からの挟持(挟みつけ)により、さらに強固に固定することができ、分割鉄芯体A4を形成する電磁鋼板の上下方向振動を軽減することができる。   Further, the divided iron core body A4 can be fixed more firmly by pressing (fitting) in the vertical direction with the divided iron core bodies Ba6a and Bb6b in addition to the press-fitting. The vibration in the vertical direction of the electrical steel sheet forming can be reduced.

また、製造する際には、分割鉄芯体Ba6a(または分割鉄芯体Bb6b)に設けた取付部19に巻線を装着または直巻巻装した分割鉄芯体A4を4個同時に、または1個ずつ順番に4個を装着したあと、分割鉄芯体Bb6b(または分割鉄芯体Ba6a)を装着しして固定子鉄芯を組み立てる。このとき、分割鉄芯体Ba6aと分割鉄芯体Bb6bとは接着、溶接あるいはその他の方法で接合するか、または、積層した歯部で保持するなど接合しないことも可能である。これにより、分割鉄芯体B6に分割鉄芯体A4を装着するには、特別な自動組立装置を必要とすることなく、手作業で組み立てることが可能である。もちろん、自動組立装置による全自動化もできる。   Further, when manufacturing, four divided iron cores A4 in which windings are mounted or directly wound on the mounting portion 19 provided on the divided iron core Ba6a (or the divided iron core Bb6b) are simultaneously or 1 After mounting four pieces in order, the divided iron core body Bb6b (or divided iron core body Ba6a) is mounted to assemble the stator iron core. At this time, the divided iron core body Ba6a and the divided iron core body Bb6b can be joined together by adhesion, welding, or other methods, or can be held together by stacked tooth portions. Thereby, in order to mount the divided iron core body A4 on the divided iron core body B6, it is possible to assemble manually without requiring a special automatic assembling apparatus. Of course, it can also be fully automated by automatic assembly equipment.

なお、本実施の形態では、分割鉄芯体Ba6a、Bb6bの双方に取付部19を設けたが、どちらか一方だけに設けてもよい。   In addition, in this Embodiment, although the attaching part 19 was provided in both divided | segmented iron cores Ba6a and Bb6b, you may provide in only one.

(実施の形態3)
図14に示すように、実施の形態2と異なるところは、磁性粉末を所定の形状に成型した圧粉磁心で形成し、回転子軸に対し直角方向に2分割した分割鉄芯体Ba6a、Bb6bの内周上を4分する位置に設けた取付部19と取付部19の中間部で各々さらに4分割した点である。
