Description

本発明は集中巻きモータの絶縁構造に関し、絶縁性能を向上すると共に絶縁作業工数を削減できるように工夫したものである。   The present invention relates to an insulating structure for a concentrated winding motor, and is devised so as to improve the insulating performance and reduce the number of insulating work steps.

電動機の高出力化を図るために、固定子鉄心を周方向の複数箇所で分割した分割鉄心を用いると共に、固定子電線を集中巻きした電動機が実用化されている。   In order to increase the output of the electric motor, an electric motor that uses a split core obtained by dividing the stator core at a plurality of locations in the circumferential direction and has concentrated stator wires is put into practical use.

図５は、上記のような電動機に用いられている、固定子電線が巻回された分割鉄心の従来構造を示す斜視図であり、図６はその断面図である。
両図に示すように、分割鉄心１は、電動機の固定子鉄心の一部を構成するものであり、このような構成となっている複数の分割鉄心１を周方向に沿い連結・結合していくことにより、固定子鉄心が構成される。逆に言えば、分割鉄心１は、固定子鉄心を周方向の複数箇所で分割したものである。 FIG. 5 is a perspective view showing a conventional structure of a split core around which a stator wire is wound, which is used in the above-described electric motor, and FIG. 6 is a cross-sectional view thereof.
As shown in both figures, the split core 1 constitutes a part of the stator core of the motor, and a plurality of split cores 1 having such a configuration are connected and coupled along the circumferential direction. By going, the stator core is constructed. In other words, the split core 1 is obtained by dividing the stator core at a plurality of locations in the circumferential direction.

ボビン２は、筒状をなすボビン本体２ａと、ボビン本体２ａの一端面側（回転子側の端面）に形成された鍔部２ｂと、ボビン本体２ａの他端面側（反回転子側の端面）に形成された鍔部２ｃとにより構成されている。
このボビン２には、集中巻きの巻線方式により固定子電線３が巻回（直巻き）されている。このようにして固定子電線３を巻回することにより、固定子コイル３０が形成される。
固定子電線３が巻回されたボビン２は、分割鉄心１に挿入・装着されて分割鉄心１に固定される。 The bobbin 2 includes a cylindrical bobbin body 2a, a flange 2b formed on one end surface side (rotor side end surface) of the bobbin body 2a, and the other end surface side (counter surface on the counter-rotor side) of the bobbin body 2a. ) And the flange portion 2c formed in the above.
The stator wire 3 is wound around the bobbin 2 by a concentrated winding method. Thus, the stator coil 30 is formed by winding the stator wire 3.
The bobbin 2 around which the stator wire 3 is wound is inserted and attached to the split iron core 1 and fixed to the split iron core 1 .

このようにして固定子電線３が巻回されたボビン２が固定されている分割鉄心１を、図７に示すように、複数個、周方向に沿い連結・結合していくことにより固定子が形成される。 As shown in FIG. 7, a plurality of the divided cores 1 around which the bobbin 2 around which the stator wire 3 is wound are fixed are connected and coupled along the circumferential direction, so that the stator is fixed. It is formed.

なお図５において、符号「３ａ」は固定子電線３の「巻き始め口線」を示し、符号「３ｂ」は固定子電線３の「巻き終わり口線」を示している。
また、巻回されている固定子電線３、即ち、固定子コイル３０の外周面の位置を特定するため、図５において巻回ずみの固定子電線３（即ち「固定子コイル３０」）の外周面のうち手前側の面を軸方向の一方の端面Ａ、この端面Ａの反対側を軸方向の他方の端面Ｂ、図５において左側の面を周方向の一方の端面Ｃ、この端面Ｃの反対側を周方向の他方の端面Ｄとして説明する。 In FIG. 5, the symbol “3a” indicates the “winding start line” of the stator wire 3, and the code “3b” indicates the “winding end line” of the stator wire 3.
Further, in order to specify the position of the outer circumference of the wound stator wire 3, that is, the stator coil 30, the outer circumference of the wound stator wire 3 (ie, the "stator coil 30") in FIG. Of the surfaces, the front side surface is one end surface A in the axial direction, the opposite side of the end surface A is the other end surface B in the axial direction, and the left side surface in FIG. 5 is the one end surface C in the circumferential direction. The opposite side will be described as the other end face D in the circumferential direction.

ところで上記の従来技術では次のような問題があった。
（１）巻き終わり口線３ｂ（図５参照）の固定が困難であり、ツナギ作業時に、反ツナギ側（図５，図６の例では軸方向の他方の端面Ｂ側）の固定子電線３に電線浮きが発生する。
（２）隣の固定子コイル３０との相互間の絶縁空間距離α（図７参照）の確保が困難である。
（３）鉄心（分割鉄心１）と電線３との沿面距離β（図７参照）の確保が困難である。
（４）隣接する固定子コイル３０間に、長方形の絶縁紙を挟むことにより、隣接する固定子コイル３０相互間の絶縁を確保しようとした場合には、絶縁紙が抜けるおそれがあるため、抜け防止策を施さなくてはならない。このような絶縁紙の抜け防止策を施すと、絶縁作業工数が増加するとともに、絶縁構造が複雑化すると共に、電動機の大型化を招来してしまう。
（５）絶縁テープを用いて絶縁を施そうとすると、絶縁工数が大幅にアップしてしまう。 By the way, the above prior art has the following problems.
(1) It is difficult to fix the winding end wire 3b (see FIG. 5), and the stator electric wire 3 on the side opposite to the flipper (on the other end face B side in the axial direction in the examples of FIGS. 5 and 6) during the work of the flipper. Electric wire floating occurs.
(2) It is difficult to secure the insulation space distance α (see FIG. 7) between the adjacent stator coils 30.
(3) It is difficult to ensure the creepage distance β (see FIG. 7) between the iron core (split core 1) and the electric wire 3.
(4) When an attempt is made to secure insulation between adjacent stator coils 30 by sandwiching rectangular insulating paper between the adjacent stator coils 30, the insulating paper may come off. You must take preventive measures. If such measures for preventing the insulation paper from being removed are taken, the number of insulation work steps will be increased, the insulation structure will be complicated, and the size of the motor will be increased.
(5) If the insulation tape is used for insulation, the number of insulation steps will be greatly increased.

本発明は上記従来技術に鑑み、絶縁性能を向上できると共に絶縁作業工数の削減ができる、集中巻きモータの絶縁構造を提供することを目的とする。   An object of the present invention is to provide an insulation structure for a concentrated winding motor that can improve insulation performance and reduce the number of insulation work steps in view of the above prior art.

Moreover, the insulation strength between adjacent stator coils improves by providing the 1st insulation part for insulation distance ensuring of the insulation paper, and the 2nd insulation part for insulation distance ensuring.
Further, by pressing the surface on the opposite side of the winding end opening line by the connecting portion, it is possible to prevent the electric wire from being lifted at the time of the work of the injuries.
Furthermore, by inserting the insulating insulation of the insulating paper between the bobbin collar and the stator coil, and between the bobbin collar and the split core, the insulation performance (creeping distance) is improved and the insulating paper Fixing can be performed easily.

本実施例では、絶縁紙１００の絶縁距離確保用第１絶縁部１０１，連結部１１０及び絶縁距離確保用第２絶縁部１０２を、固定子コイル３０に巻きつけ、第１〜第４の挿入絶縁部１２１〜１２４を、ボビン２の鍔部２ｂと巻線３０との隙間や、ボビン２の鍔部２ｃと分割鉄心１との隙間に差し込んだだけで、絶縁作業が完了する。このため、絶縁作業が容易になり絶縁作業工数を削減することができる。   In the present embodiment, the first insulating portion 101 for securing the insulating distance of the insulating paper 100, the connecting portion 110, and the second insulating portion for securing the insulating distance 102 are wound around the stator coil 30, and the first to fourth insertion insulations are wound. The insulation work is completed simply by inserting the parts 121 to 124 into the gap between the flange 2b of the bobbin 2 and the winding 30 or the gap between the flange 2c of the bobbin 2 and the split core 1. For this reason, insulation work becomes easy and the number of insulation work steps can be reduced.

また連結部１１０により、固定子コイル３０の外周面のうち軸方向の他方の端面Ｂを押え、軸方向の一方の端面Ａをテープ２００により固定することにより、巻き終わり口線３ｂの固定ができ、ツナギ作業時において端面Ｂ側の固定子電線３の電線浮きの発生を防止することができる。 In addition, the winding end mouth wire 3b can be fixed by pressing the other end surface B in the axial direction of the outer peripheral surface of the stator coil 30 and fixing the one end surface A in the axial direction with the tape 200 by the connecting portion 110. It is possible to prevent the floating of the stator electric wire 3 on the end face B side during the work of jumping.

更に、絶縁距離確保用第１絶縁部１０１及び絶縁距離確保用第２絶縁部１０２を備えることにより、隣接する固定子コイル３０間の絶縁強度を向上させることができる。
また、第１挿入絶縁部１２１と第３挿入絶縁部１２３を、固定子コイル３０と一方の鍔部２ｂとの間に挿入することにより、絶縁紙１００が固定子の外に飛び出すのを防止することができる。
また、第２挿入絶縁部１２２と第４挿入絶縁部１２４を、分割鉄心１と他方の鍔部２ｃとの間に挿入することにより、沿面距離の確保ができるとともに、絶縁紙１００の固定と、固定子電線３が絶縁紙１００から漏れ出ることを防止できる。 Furthermore, the insulation strength between the adjacent stator coils 30 can be improved by providing the first insulation part 101 for securing the insulation distance and the second insulation part 102 for securing the insulation distance.
Further, by inserting the first insertion insulating portion 121 and the third insertion insulating portion 123 between the stator coil 30 and the one flange 2b, the insulating paper 100 is prevented from jumping out of the stator. be able to.
Further, by inserting the second insertion insulating portion 122 and the fourth insertion insulating portion 124 between the split iron core 1 and the other flange 2c, it is possible to secure a creepage distance, and to fix the insulating paper 100; It is possible to prevent the stator wire 3 from leaking out from the insulating paper 100.
