The stator is composed of a plurality of tooth portions 202 and a yoke portion 203 composed of magnetic powder and connecting the tooth portions, and has a stator core 204 formed by combining them. .

また、この種の電動機には固定子鉄芯を電磁鋼板を打抜き・積層した積層鉄芯体と磁性粉末を使用した圧粉磁心を併用した固定子鉄芯からなる固定子とそれを製造する方法が提案されている(例えば、特許文献2参照)。   Also, in this type of electric motor, a stator comprising a stator iron core using a laminated iron core body obtained by punching and stacking magnetic steel sheets from a stator iron core and a dust core using magnetic powder, and a method for manufacturing the same Has been proposed (see, for example, Patent Document 2).

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.

Therefore, in order to ensure a predetermined amount of magnetic flux, the cross-sectional area (the axial length of the tooth portion x the width dimension) needs to be configured to be larger than the laminated iron core body, and as a result, the tooth portion is wound. Since the circumference of the winding becomes long and the loss consumed by the winding becomes large, there is a problem that the efficiency of the electric motor is lowered.

(Embodiment 1)
As shown in FIG. 1 to FIG. 6, the capacitor motor of the present invention has four divided iron cores A4 each of which mainly forms a tooth portion 3 of a stator iron core 2 having four slots 1. A magnetic path is formed as the yoke portion 5 on the outer peripheral side of the divided iron core A4 and the slot 1, and divided into divided iron cores B6 formed longer than the thickness dimension in the rotor axial direction of the divided iron core A4. . Each of the divided iron cores A4 is formed by punching and laminating electromagnetic steel plates, and each tooth portion 3 is provided with an A-phase winding 8 or a B-phase winding 9 wound around an insulating bobbin 7. The divided iron core body A4 to which the A-phase winding 8 is mounted and the divided iron core body A4 to which the B-phase winding 9 is mounted are arranged alternately and radially around the rotor hole 18. The The concave core A11 and the convex part A12 of the protrusion 10 provided at the outer peripheral end portion of the divided iron core A4 are arranged on the outer peripheral portion and formed of a dust core formed by molding magnetic powder into a predetermined shape. The stator 16 is configured by combining the convex portion B14 and the concave portion B15 of the notch 13 of the body B6 with a simple mechanical assembly such as press-fitting or by a combination of these methods such as welding and bonding as necessary. The A slot insulating film 17 is disposed together with the insulating bobbin 7 to electrically insulate between the winding and the stator core 2.

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、圧入嵌合または組合せなどで分割鉄芯体A4と分割鉄芯体B6の合体、組立ができる。   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, the split iron core body A4 and the split iron core body B6 can be combined and assembled by press fitting or combination.

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、4の倍数個であればいくつでもよく、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 this embodiment, the number of slots of the stator iron core is four, but any number of slots is acceptable as long as it is a multiple of four, and the insulation between each phase winding and the stator iron core 2 is mainly used. However, it is also possible to use an insulating film and powder.

(実施の形態2)
図7〜図10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6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)
7 to 10, 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. Also, the same components as those in FIGS. 1 to 6 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、磁路断面積を削減できる。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の内周部を分割鉄芯体Aまたはスロット数と同数に等分する分割鉄芯体Aまたはスロット数と同数に等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 with, the magnetic path cross-sectional area can be reduced. 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, the inner peripheral portion of the divided iron cores Ba6a and Bb6b is divided into the same number as the divided iron core A or the number of slots. On the other hand, since the divided iron core A is disposed, the circumferential positioning of the divided iron core A can be accurately and reliably and easily fixed.

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Baと分割鉄芯体Bb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4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 Ba and the divided iron core Bb may be joined by bonding, welding, or other methods, or may be held without being stacked or stacked. Thereby, in order to mount the divided iron core body 4 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A4の個数およびスロット1の個数は4、極数は2としたが、スロット1の個数、極数とも4の倍数であればいくつの場合でもよい。   In the present embodiment, the number of divided iron cores A4 and the number of slots 1 are 4, and the number of poles is 2. However, any number of slots 1 and the number of poles may be used as long as both are the multiples of 4. .

(実施の形態3)
図11において、実施の形態2と異なるところは、分割鉄芯体A4を回転子軸に直角で径方向に磁化容易な特性を持つ方向性電磁鋼板(方向性珪素鋼板)を打抜き・積層して構成した点である。
(Embodiment 3)
In FIG. 11, the difference from the second embodiment is that a divided iron core A4 is formed by punching and laminating a directional electrical steel sheet (directional silicon steel sheet) having a property of being easily magnetized in a radial direction perpendicular to the rotor axis. It is a point that has been configured.

上記構成において、分割鉄芯体A4−1では、回転子軸に対し垂直に放射する方向に磁力線が通りやすいことになるため、一般の無方向性電磁鋼板を打抜き・構成した場合に比して磁束密度を高めることが可能で、さらに磁路断面積の削減が可能となることから各々の歯部3に巻装する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し、電動機効率を向上できる。   In the above configuration, in the split iron core A4-1, the magnetic lines of force easily pass in the direction of radiating perpendicularly to the rotor axis, so compared with the case of punching and configuring a general non-oriented electrical steel sheet. Since the magnetic flux density can be increased and the cross-sectional area of the magnetic path can be further reduced, the circumference of the A-phase winding 8 or the B-phase winding 9 wound around each tooth portion 3 is shortened. Thus, the loss of the windings is reduced by reducing the resistance value of the windings, and the motor efficiency can be improved.

(実施の形態4)
図12、図13に示すように、実施の形態2と異なるところは、分割鉄芯体A4−2は電磁鋼板を周方向に積層し、また、分割鉄芯体A4−2は分割鉄芯体B6との接合面および回転子孔18の対向面において、軸方向長さがその他の部分よりも長く構成した点である。
(Embodiment 4)
As shown in FIG. 12 and FIG. 13, the difference from the second embodiment is that the divided iron core A4-2 is laminated with magnetic steel sheets in the circumferential direction, and the divided iron core A4-2 is divided iron core. In the joint surface with B6 and the opposing surface of the rotor hole 18, the axial length is longer than that of the other portions.

上記構成において、分割鉄芯体A4−2の巻線を巻装する歯部の打抜き・積層枚数不変すなわち断面積を変更することなく、分割鉄芯体A4−2の打抜き形状を変更することで分割鉄芯体B6a−1、6a−2との接合面および回転子(図示せず)の対向面の軸方向長さを延長し、分割鉄芯体B6a−1、6a−2との接合面面積および回転子対向面の面積を増大し、その結果、分割鉄芯体B6a−1、6a−2との接合部の接触抵抗を低減すると共に回転子対向面の面積を拡大し空隙部磁束密度を低減することで電動機効率を向上することができる。   In the above configuration, by changing the punching shape of the split iron core body A4-2 without changing the punching / stacking number of the tooth portion around which the winding of the split iron core body A4-2 is wound, i.e., changing the cross-sectional area. Extending the axial length of the joint surface with the split iron core bodies B6a-1 and 6a-2 and the opposing surface of the rotor (not shown), and the joint surface with the split iron core bodies B6a-1 and 6a-2 The area and the area of the rotor facing surface are increased. As a result, the contact resistance of the joint portion with the divided iron cores B6a-1 and 6a-2 is reduced, and the area of the rotor facing surface is increased to increase the gap magnetic flux density. It is possible to improve the motor efficiency by reducing.

なお、本実施の形態では、分割鉄芯体A4−2の個数およびスロット1の個数は8、極数は4としたが、スロット1の個数、極数とも4の倍数であればいくつの場合でもよい。   In the present embodiment, the number of divided iron cores A4-2 and the number of slots 1 are 8 and the number of poles is 4. However, the number of slots 1 and the number of poles are multiples of 4 in any number of cases. But you can.

(実施の形態5)
図14に示すように、実施の形態4と異なるところは、分割鉄芯体A4−3は同一形状で打抜き・積層してなり、回転子孔18の外周面に対しほぼ同寸法の空隙を介して配置された構成とした点である。
(Embodiment 5)
As shown in FIG. 14, the difference from the fourth embodiment is that the divided iron core A4-3 is punched and laminated in the same shape, with a gap having substantially the same dimension with respect to the outer peripheral surface of the rotor hole 18. It is the point which was set as the structure arranged.

上記構成のおいて、分割鉄芯体A4−3は1種類の打抜き金型のみで同鉄芯の打抜き・積層が可能となり金型構造の簡略化による合理化が可能となる。   In the above configuration, the split iron core body A4-3 can be punched and laminated with only one type of punching die, and can be rationalized by simplifying the die structure.

なお、以上の実施の形態1〜3および6では、4スロットの固定子鉄芯とし、実施の形態4,5では、8スロットの固定子鉄芯としたが、本発明の効果はスロット数に限定されることは無く、コンデンサ電動機のほか集中巻で巻線を巻装するその他の電動機に対しても有効となる。また、分割部分の組立一体化は接着、溶接などのほか、機械的組立その他に対応した構造も可能である。   In Embodiments 1 to 3 and 6 described above, a 4-slot stator iron core is used, and in Embodiments 4 and 5, an 8-slot stator iron core is used.
