Description

本発明は、例えば空調機器や冷凍機器、給湯機器や自動車用途で使用される電動機の固定子に関する。   The present invention relates to a stator of an electric motor used in, for example, an air conditioner, a refrigeration device, a hot water supply device, and an automobile.

エアコンや冷蔵庫、給湯機や自動車用途等に使用される電動機要素は、近年、本体の省エネルギー化に伴い、インダクションモータより高効率であるブラシレスモータが使用されるようになってきた。このブラシレスモータにおいても固定子に巻線を行う手段としてコイルをインサートする方式があり、この種の電動機の固定子は、図９に示すように固定子巻線のコイルエンド部の異極間に生じる電位差を下げて、絶縁性能を向上させるものが提案されている（例えば、特許文献１参照）。特許文献１に記載の固定子は、固定子鉄心２０に固定子巻線２１のコイルエンド部に相間絶縁紙２３を挿入しコイルエンド縛り糸２２で固定した状態で、電位差の生じる異極間の絶縁を確保できる構成となっている。   In recent years, brushless motors, which are more efficient than induction motors, have been used for motor elements used for air conditioners, refrigerators, water heaters, automobiles, and the like with the energy saving of the main body. Even in this brushless motor, there is a method of inserting a coil as a means for winding the stator, and the stator of this type of electric motor is provided between different poles of the coil end portion of the stator winding as shown in FIG. There has been proposed one that lowers the generated potential difference and improves insulation performance (see, for example, Patent Document 1). In the stator described in Patent Document 1, the interphase insulating paper 23 is inserted into the coil end portion of the stator winding 21 in the stator core 20 and is fixed with the coil end binding yarn 22, and between different poles where a potential difference occurs. It has a configuration that can ensure insulation.

また、密閉型電動圧縮機の固定子として、図１０に示すように固定子鉄心の端面に液晶ポリマー樹脂、ポリフェニレンサルファイド樹脂等で成型されたインシュレータを用いた電動機が提案されている（例えば、特許文献２参照）。特許文献２に記載の固定子は、固定子鉄心３０にインシュレータ３２を装着し、突極集中巻線３１を行うことで、電位差の生じる位相間の絶縁を確保できる構成となっている。   Further, as a stator of a hermetic electric compressor, an electric motor using an insulator molded with liquid crystal polymer resin, polyphenylene sulfide resin or the like on the end face of the stator core as shown in FIG. 10 has been proposed (for example, a patent) Reference 2). The stator described in Patent Document 2 has a configuration in which insulation between phases in which a potential difference occurs is secured by mounting an insulator 32 on a stator core 30 and performing salient pole concentrated windings 31.

電動機の固定子巻線の絶縁方法としては、一般的に電位差が最も大きい箇所（異極間）に絶縁を行う必要があるが、例えば図４のブラシレスモータの結線図に示すような場合、各相（Ｕ相、Ｖ相、Ｗ相）と中性点間は電位差が相間電圧の１／√３となるので、絶縁を積極的に行っていなかった。但し、固定子巻線への印加電圧が高い用途においては、中性点接続線は各相（Ｕ相、Ｖ相、Ｗ相）との絶縁を行うために、中性点絶縁チューブ等を挿入し電気的に絶縁を行っている。しかしながら、この方法では電動機が多極数化になる程、中性点へ集まる中性点接続線が増えることで、作業工数大やコイルエンド寸法大となる。一方、ブラシレスモータにおいては通常、回転子に永久磁石を使用しており、その永久磁石を固定子巻線に高電圧の電流を印加し着磁を行う工法がある。この着磁工法は、１回〜２回の高電圧で且つ大電流を固定子巻線に印加することで永久磁石への着磁が可能となるが、固定子巻線には着磁ストレスを与えることとなる為、固定子巻線の絶縁性能が低い箇所で着磁スパークが発生し固定子が耐圧不良に至る場合がある。   As a method for insulating a stator winding of an electric motor, it is generally necessary to insulate a portion having a largest potential difference (between different poles). For example, as shown in the connection diagram of the brushless motor in FIG. Since the potential difference between the phase (U phase, V phase, W phase) and the neutral point is 1 / √3 of the interphase voltage, insulation was not positively performed. However, in applications where the voltage applied to the stator winding is high, the neutral point connection line is insulated from each phase (U phase, V phase, W phase). It is electrically insulated. However, in this method, as the number of electric motors increases, the number of neutral point connection lines gathered to the neutral point increases, resulting in a large work man-hour and a large coil end size. On the other hand, in a brushless motor, a permanent magnet is usually used for a rotor, and there is a method of magnetizing the permanent magnet by applying a high voltage current to a stator winding. In this magnetizing method, the permanent magnet can be magnetized by applying a high current and high current to the stator winding once or twice, but the stator winding is subjected to magnetization stress. Therefore, there is a case where a magnetized spark is generated at a location where the insulation performance of the stator winding is low and the stator has a breakdown voltage failure.

また、図１０に示す構造ではコイルエンド絶縁を行う場合に、液晶ポリマー樹脂、ポリフェニレンサルファイド樹脂、ポリブチレンテレフタレート樹脂などによるインシュレータ成型品と中性点接続端子等（図示省略）を使用し、コイルエンドと中性点接続線が直接触れないような構造で電気的に絶縁をする方法があるが、この方法ではインシュレータの樹脂使用量の増大或いは樹脂成型品の金型費用等が必要である。   Further, in the structure shown in FIG. 10, when coil end insulation is performed, an insulator molded product made of liquid crystal polymer resin, polyphenylene sulfide resin, polybutylene terephthalate resin, etc., and a neutral point connection terminal (not shown) are used. There is a method of electrically insulating with a structure in which the neutral point connection line is not directly touched, but this method requires an increase in the amount of resin used for the insulator or a mold cost for the resin molded product.

これらの構造も前記記載同様に多極数化になる程、中性点へ集まる中性点接続線は増えるので、インシュレータの形状が複雑になり構成が難しくなる。   As described above, as the number of poles increases, the number of neutral point connection lines gathering to the neutral point increases as described above, so that the shape of the insulator becomes complicated and the configuration becomes difficult.

本発明は、前記従来の問題に鑑みてなされたものにおいて、その目的は、電動機の固定子を回転子の着磁ヨークとして使用しても着磁ストレスに強く、多極数化になっても安価で更に絶縁性能を向上した構成を提供するものである。   The present invention has been made in view of the above-described conventional problems. The object of the present invention is to use a stator of an electric motor as a magnetizing yoke of a rotor, or to resist magnetization stress and to increase the number of poles. The present invention provides a configuration that is inexpensive and further improves the insulation performance.

以下、本発明における実施の形態について、図面を参照しながら説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１は、本発明の一実施例であり、電動機の固定子の構造断面図である。この図に示すように、本発明の電動機の固定子は複数個のスロットを配置された薄板鉄板を複数枚積層した固定子鉄心１０と、固定子鉄心のスロットに巻線を施した固定子巻線１１と、固定子巻線１１はリード線１５に接続されている。更に、固定子巻線１１はコイルエンド縛り糸１４で固定されており、この電動機の固定子において固定子巻線１１のコイルエンド外周部と、中性点に集まる複数本の中性点接続線１２の間に、帯状の絶縁フィルムを固定子巻線１１のコイルエンドを全周又は、一部を巻くように配置したコイルエンド絶縁フィルム１３を挿入し、コイルエンド縛り糸１４で固定子巻線のコイルエンドとコイルエンド絶縁フィルム１３を一緒に結束し構成されている。   FIG. 1 is a structural sectional view of a stator of an electric motor according to an embodiment of the present invention. As shown in this figure, the stator of the electric motor of the present invention includes a stator core 10 in which a plurality of thin steel plates each having a plurality of slots are stacked, and a stator winding in which windings are provided in the slots of the stator core. The wire 11 and the stator winding 11 are connected to the lead wire 15. Further, the stator winding 11 is fixed with a coil end tie thread 14, and a plurality of neutral point connecting lines gathered at the coil end outer peripheral portion of the stator winding 11 and the neutral point in the stator of this electric motor. 12, a coil end insulating film 13 in which a coil-shaped insulating film is arranged so as to wind all around or part of the coil end of the stator winding 11 is inserted, and the stator winding is wound with a coil end binding thread 14. The coil end and the coil end insulating film 13 are bundled together.

図２は本発明の一実施例であり、図１に示す電動機の固定子の斜視図である。この図に示すように、スロットより引き出された複数本の中性点接続線１２はコイルエンド絶縁フィルム１３によって、固定子巻線１１と絶縁され更にコイルエンド縛り糸１４で結束される構成である。   FIG. 2 is a perspective view of the stator of the electric motor shown in FIG. 1 according to an embodiment of the present invention. As shown in this figure, a plurality of neutral point connecting wires 12 drawn out from the slot are insulated from the stator winding 11 by a coil end insulating film 13 and are further bound by a coil end binding thread 14. .

次に上記のように構成された電動機の作用を説明する。固定子巻線１１のコイルエンドと中性点接続線１２はコイルエンド絶縁フィルム１３によって、電気的に絶縁されたことで、絶縁耐力が向上する効果があるので、例えば永久磁石を配置した回転子に対して固定子巻線１１を着磁ヨークとした場合は、着磁ストレスの影響が受けにくいので着磁スパークの発生を抑えることが出来る。また、電動機の固定子の取り扱いで、固定子巻線１１のコイルエンドに傷や圧痕或いは金属の異物等が混入した場合でもコイルエンド絶縁フィルム１３があることで電気的に絶縁され、上述同様に絶縁性能の向上を図ることが可能である。   Next, the operation of the electric motor configured as described above will be described. Since the coil end of the stator winding 11 and the neutral point connection line 12 are electrically insulated by the coil end insulating film 13, there is an effect of improving the dielectric strength. For example, a rotor in which a permanent magnet is arranged On the other hand, when the stator winding 11 is a magnetized yoke, the occurrence of magnetized sparks can be suppressed since it is not easily affected by the magnetizing stress. In addition, when the stator of the motor is handled, even if scratches, indentations, metal foreign matters, etc. are mixed into the coil end of the stator winding 11, the coil end insulating film 13 is electrically insulated and the same as described above. It is possible to improve the insulation performance.

This coil end insulating film is mainly made of polyethylene terephthalate resin having a thickness of 0.075 mm to 0.3 mm. However, resin members such as polyethylene naphthalate resin and polyphenylene sulfide resin can obtain the same effect as polyethylene terephthalate resin. .

This connection is a connection diagram in the case where the number of poles is 6 and the stator is 9 slots. In such a connection method, the total number of neutral point connection lines gathered at the neutral point is nine. When the number of poles further increases, the number of neutral point connection lines increases, and when the stator is used in a magnetized yoke, insulation performance is required, so that the present invention provides a more effective effect.

図５は本発明の一実施例であり、図４に示す結線図と固定子巻線の結線方法を示すものである。この図が示す通り、一つの中性点には９スロット全ての中性点接続線を結線する必要があるが、これらを全ての中性線接続線は中性点絶縁チューブ１６に挿入されている。更に固定子巻線のコイルエンドを絶縁する方法としては、図３に示すコイルエンド絶縁フィルム１３を固定子巻線のコイルエンド全周又は、一部を巻くことで、安価で作業的に容易な手段で固定子巻線のコイルエンドと中性点接続線を絶縁することが可能である。   FIG. 5 shows an embodiment of the present invention and shows the connection diagram shown in FIG. 4 and a method of connecting the stator windings. As shown in this figure, it is necessary to connect all 9 slot neutral point connection lines to one neutral point, but all these neutral line connection lines are inserted into the neutral point insulation tube 16. Yes. Furthermore, as a method of insulating the coil end of the stator winding, the coil end insulating film 13 shown in FIG. By means, it is possible to insulate the coil end of the stator winding from the neutral point connection line.

It is. The coil end insulating film 13 is obtained by adding a neutral point fixing portion to the shape of the coil end insulating film 13 shown in FIG. 3 and bending the neutral point fixing portion into an L shape along the end surface of the coil end. Here, the neutral point connecting line 12 collected at the neutral point and the neutral point insulating tube 16 shown in FIG.

図３に示すコイルエンド絶縁フィルム１３では、中性点絶縁チューブ１６はコイルエンド外周部で固定する必要があるが、図６に示すコイルエンド絶縁フィルム１３では中性点絶縁チューブ１６をコイルエンドの端面に置くことが可能となり、中性点絶縁チューブ１６が安定することで巻線作業性も改善され、低価格の物作りの効果が得られる。   In the coil end insulating film 13 shown in FIG. 3, it is necessary to fix the neutral point insulating tube 16 at the outer periphery of the coil end. In the coil end insulating film 13 shown in FIG. It becomes possible to place it on the end face, and the neutral point insulating tube 16 is stabilized, so that the workability of winding is improved, and the effect of making a low-priced product is obtained.

図８は本発明の一実施例の、コイルエンド絶縁フィルム１３を示す図である。このコイルエンド絶縁フィルムは、図６記載の形状に更に横ズレ防止突起を追加し、この横ズレ防止突起を固定子巻線のスロットに数箇所（図６では４箇所）に挿入することで、更に巻線作業性が改善され、低価格の物作りの効果が得られる。     FIG. 8 is a view showing the coil end insulating film 13 according to one embodiment of the present invention. This coil end insulating film is further added with a lateral misalignment preventing projection in the shape shown in FIG. 6, and the lateral misalignment preventing projection is inserted into the slots of the stator winding at several locations (four locations in FIG. 6). Furthermore, winding workability is improved, and the effect of making a low-priced product can be obtained.
