Description
本発明は回転電機およびそれを用いた洗濯機、ポンプ、家庭用・産業用機器に関するものである。 The present invention relates to a rotating electrical machine and a washing machine, pump, and household / industrial equipment using the same.
回転電機の固定子巻線には、一般に、電気伝導性の優れた銅系材料が用いられている。また、固定子巻線の導体と被覆電線の導体とは、ハンダまたはウォーターウェルダー等の方法で接続される。 Generally, a copper-based material having excellent electrical conductivity is used for a stator winding of a rotating electric machine. The conductor of the stator winding and the conductor of the covered electric wire are connected by a method such as solder or water welder.
一方、自動車分野においては、車両の軽量化のため、比重が銅系材料の約３分の１であるアルミニウム系材料を導体に用いたアルミ電線が提案されている。このようなアルミ電線では、銅系材料の端子とアルミニウム系材料の導体とによる異種金属同士の電気接続が必要となるため、この接続部分に水分が付着すると、接触腐食が生じる可能性がある。そこで、このような接触腐食を防止するため、例えば下記特許文献１には、銅端子とアルミニウム導体との間に亜鉛層を設けて隔絶することが開示されている。また、下記特許文献２には、銅端子とアルミニウム導体との境界露出部を樹脂材料で覆うことにより、この境界露出部に水が浸入するのを防ぐことが開示されている。 On the other hand, in the automobile field, an aluminum electric wire using an aluminum-based material whose specific gravity is about one-third that of a copper-based material as a conductor has been proposed to reduce the weight of the vehicle. Such an aluminum electric wire requires electrical connection between dissimilar metals using a copper-based material terminal and an aluminum-based material conductor, and contact moisture may occur if moisture adheres to this connection portion. Therefore, in order to prevent such contact corrosion, for example, Patent Document 1 below discloses that a zinc layer is provided between a copper terminal and an aluminum conductor for isolation. Patent Document 2 below discloses that the boundary exposed portion between the copper terminal and the aluminum conductor is covered with a resin material to prevent water from entering the boundary exposed portion.
しかしながら、特許文献１に記載された構造は、水の浸入を防ぐものではないので、水が浸入した場合に亜鉛層の腐食が進行し、長期的な防食効果を維持することは難しい。 However, since the structure described in Patent Document 1 does not prevent water from entering, corrosion of the zinc layer proceeds when water enters, and it is difficult to maintain a long-term anticorrosive effect.
また、特許文献２に記載された技術は、電線と端子とを単純に接続する場合を想定したものであるため、接続する対象が、回転電機の固定子巻線同士の場合や固定子巻線と電線の場合には、樹脂材料でこれらを固定する作業が容易ではない。 Moreover, since the technique described in patent document 2 assumes the case where an electric wire and a terminal are simply connected, when the connection object is between stator windings of a rotating electrical machine, or the stator winding In the case of an electric wire, it is not easy to fix them with a resin material.
本発明の目的は、製造ラインでの高い作業性を保ちつつ、固定子巻線と被覆電線との接続部分や固定子巻線同士の接続部分の腐食を防止できる回転電機を提供することにある。 The objective of this invention is providing the rotary electric machine which can prevent the corrosion of the connection part of a stator coil | winding and a covered electric wire, and the connection part of stator windings, maintaining high workability | operativity in a production line. .
上記目的を達成するために、本発明は、固定子鉄心に形成された複数のスロット内にティースを取り囲むように固定子巻線が施された固定子と、この固定子に所定のギャップを介して回転自在に支持された回転子を備えた回転電機において、前記固定子巻線と被覆電線との接続部分又は前記固定子巻線同士の接続部分を収縮可能なチューブに収納し、このチューブ内の隙間をシリコーンで塞ぐ。 In order to achieve the above object, the present invention provides a stator in which a stator winding is provided so as to surround teeth in a plurality of slots formed in the stator core, and a predetermined gap is provided in the stator. In a rotating electrical machine including a rotor that is rotatably supported, the connecting portion between the stator winding and the covered electric wire or the connecting portion between the stator windings is housed in a shrinkable tube, Seal the gap with silicone.
本発明によれば、製造ラインでの高い作業性を保ちつつ、固定子巻線と被覆電線との接続部分や固定子巻線同士の接続部分の腐食を防止可能な回転電機を提供できる。 ADVANTAGE OF THE INVENTION According to this invention, the rotary electric machine which can prevent the corrosion of the connection part of a stator winding and a covered electric wire and the connection part of stator windings can be provided, maintaining the high workability | operativity in a production line.
以下、本発明の実施形態について、図面を用いて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
図１は、一実施形態として、洗濯乾燥機のメインモータとして用いられた回転電機１４の断面図である。回転電機１４は、固定子７、回転子９、エンドブラケットＡ１５、エンドブラケットＢ１６、軸受１２とから構成されている。 FIG. 1 is a cross-sectional view of a rotating electrical machine 14 used as a main motor of a washing / drying machine as an embodiment. The rotating electrical machine 14 includes a stator 7, a rotor 9, an end bracket A15, an end bracket B16, and a bearing 12.
固定子７は、固定子鉄心８に形成された複数のスロット内に、ティースを取り囲むように固定子巻線２が施されて構成されている。また、回転子９は、回転子鉄心１０及び軸１１を有しており、固定子７の内周側に所定のギャップを介し、軸受１２によってエンドブラケットＡ１５、エンドブラケットＢ１６により回転自在に支持されている。 The stator 7 is configured such that the stator winding 2 is provided in a plurality of slots formed in the stator core 8 so as to surround the teeth. The rotor 9 has a rotor core 10 and a shaft 11, and is rotatably supported by the end bracket A15 and the end bracket B16 by a bearing 12 through a predetermined gap on the inner peripheral side of the stator 7. ing.
図２は、シリコーン５と熱収縮チューブ６を使用して固定子巻線２の異種金属接続部における腐食防止を図る前の状態を示している。固定子巻線２は固定子鉄心８に巻装され、固定子巻線２の端末１３は後工程（固定子巻線２の導体と被覆電線３の導体４との接続等）を考慮して約１００ｍｍ（製品の種類によって異なる）の長さが確保されている。 FIG. 2 shows a state before the prevention of corrosion at the dissimilar metal connection portion of the stator winding 2 using the silicone 5 and the heat shrinkable tube 6. The stator winding 2 is wound around the stator core 8, and the terminal 13 of the stator winding 2 is in consideration of a later process (connection between the conductor of the stator winding 2 and the conductor 4 of the covered wire 3). A length of about 100 mm (depending on the type of product) is secured.
（実施例１）図３は、固定子巻線２と被覆電線３との接続に関する実施例１に係る回転電機１４を示している。本実施例では、固定子巻線２の導体と被覆電線３の導体４とを端子１で圧着して電気接続部Ａ１７を形成し、この接続部分を収縮可能なチューブに収納し、このチューブ内の隙間をシリコーン５で塞ぐ。この電気接続部Ａ１７へシリコーン５を被覆する方法としては、電気接続部Ａ１７に直接塗布しても良いし、チューブ内に適量を挿入することで間接的に電気接続部Ａ１７へ流し込んでも良い。 (Embodiment 1) FIG. 3 shows a rotating electrical machine 14 according to Embodiment 1 relating to the connection between the stator winding 2 and the covered electric wire 3. In this embodiment, the conductor of the stator winding 2 and the conductor 4 of the covered wire 3 are crimped by the terminal 1 to form the electrical connection portion A17, and this connection portion is housed in a contractible tube. The gap is closed with silicone 5. As a method of covering the electrical connection portion A17 with the silicone 5, it may be applied directly to the electrical connection portion A17, or may be poured indirectly into the electrical connection portion A17 by inserting an appropriate amount into the tube.
以下、固定子巻線２と被覆電線３との接続方法について、詳細に説明する。まず、図４に示す通り、電気接続部Ａ１７において、固定子巻線２の導体（アルミニウム系材料）と被覆電線３の導体４（銅系材料）とを、端子１（銅系材料）によって圧着することにより、電気的に接続する。ここで、電気接続部Ａ１７は異種金属による接続となるため、このままだと、接続部に水分が付着した場合に、端子１と固定子巻線２の導体に異種金属の接触腐食が生じる。 Hereinafter, a method for connecting the stator winding 2 and the covered electric wire 3 will be described in detail. First, as shown in FIG. 4, in the electrical connection portion A17, the conductor of the stator winding 2 (aluminum-based material) and the conductor 4 (copper-based material) of the covered electric wire 3 are crimped by the terminal 1 (copper-based material). To make an electrical connection. Here, since the electrical connection portion A17 is connected by a dissimilar metal, if moisture remains attached to the connection portion, contact corrosion of the dissimilar metal occurs in the conductors of the terminal 1 and the stator winding 2.
そこで、シリコーン５を電気接続部Ａ１７に塗布した後、図５のように、その周囲に熱収縮チューブ６を被せる。次に、熱収縮チューブ６を加熱して収縮させることにより、熱収縮チューブ６がシリコーン５と固着する。このとき、熱収縮チューブ６内の余分なシリコーン５は、熱収縮チューブ６内の隙間を埋めながら両端に移動し、図６に示すような状態となる。 Therefore, after the silicone 5 is applied to the electrical connection portion A17, the heat shrinkable tube 6 is placed around the periphery as shown in FIG. Next, the heat-shrinkable tube 6 adheres to the silicone 5 by heating and shrinking the heat-shrinkable tube 6. At this time, the excess silicone 5 in the heat-shrinkable tube 6 moves to both ends while filling the gap in the heat-shrinkable tube 6, and a state as shown in FIG. 6 is obtained.
結果として、電気接続部Ａ１７の両端からの水の浸入経路が塞がれ、外部から水分が浸入するのを防止でき、長期的に防食効果を維持することが可能となる。この一連の作業は、固定子７の製造工程上で作業できるので量産体制に影響を及ぼさない。 As a result, the intrusion path of water from both ends of the electrical connection portion A17 is blocked, it is possible to prevent moisture from entering from the outside, and the anticorrosion effect can be maintained for a long time. Since this series of operations can be performed in the manufacturing process of the stator 7, it does not affect the mass production system.
次に、固定子巻線２と被覆電線３との別の接続方法を説明する。 Next, another method for connecting the stator winding 2 and the covered electric wire 3 will be described.
作業方法としては、先に、熱収縮チューブ６の一端側を収縮させておき、熱収縮チューブ６の他端側からシリコーン５を適量注入する。その後、固定子巻線２の導体と被覆電線３の導体４とが端子１によって圧着された、図４に示す状態の電気接続部Ａ１７を、熱収縮チューブ６内に挿入する。そして、図５の状態で熱収縮チューブ６に熱を加えると、熱収縮チューブ６が収縮してシリコーン５と固着し、最終的に図６の状態になる。 As a working method, first, one end side of the heat shrinkable tube 6 is contracted, and an appropriate amount of silicone 5 is injected from the other end side of the heat shrinkable tube 6. Thereafter, the electrical connection portion A17 in the state shown in FIG. 4 in which the conductor of the stator winding 2 and the conductor 4 of the covered wire 3 are crimped by the terminal 1 is inserted into the heat shrinkable tube 6. When heat is applied to the heat-shrinkable tube 6 in the state shown in FIG. 5, the heat-shrinkable tube 6 contracts and adheres to the silicone 5, and finally the state shown in FIG.
この接続方法によれば、適量のシリコーン５を熱収縮チューブ６内に挿入可能となる。すると、常に一定の量を挿入できるため品質の向上につながるだけでなく、シリコーン５を容易に挿入できるので製造ラインでの作業性も向上する。 According to this connection method, an appropriate amount of silicone 5 can be inserted into the heat-shrinkable tube 6. Then, since a constant amount can be always inserted, not only the quality is improved, but also the silicone 5 can be easily inserted, so that workability on the production line is also improved.
電気接続部Ａ１７の固定子巻線２の導体と被覆電線３の導体４の材質の組合せは、アルミニウム系材料と銅系材料、アルミニウム系材料とアルミニウム系材料、銅系材料とアルミニウム系材料の組合せが考えられる。導体本数は３本以上でも良く、組合せはアルミニウム系材料とアルミニウム系材料、アルミニウム系材料と銅系材料の組合せになる。 The combination of the conductor of the stator winding 2 of the electrical connection portion A17 and the material of the conductor 4 of the covered wire 3 is a combination of an aluminum-based material and a copper-based material, an aluminum-based material and an aluminum-based material, and a copper-based material and an aluminum-based material. Can be considered. The number of conductors may be three or more, and the combination is a combination of an aluminum-based material and an aluminum-based material, and an aluminum-based material and a copper-based material.
（実施例２）図７は、固定子巻線２同士の接続に関する実施例２に係る回転電機１４を示している。本実施例では、固定子巻線２の導体同士を端子１で圧着して電気接続部Ｂ１８を形成し、この接続部分を収縮可能なチューブに収納し、このチューブ内の隙間をシリコーン５で塞ぐ。この電気接続部Ｂ１８へシリコーン５を被覆する方法としては、電気接続部Ｂ１８に直接塗布しても良いし、チューブ内に適量を挿入することで間接的に電気接続部Ｂ１８へ流し込んでも良い。 (Embodiment 2) FIG. 7 shows a rotating electrical machine 14 according to Embodiment 2 relating to the connection between the stator windings 2. In this embodiment, the conductors of the stator winding 2 are crimped together with the terminal 1 to form an electrical connection portion B18. This connection portion is housed in a shrinkable tube, and the gap in the tube is closed with silicone 5. . As a method of coating the electrical connection portion B18 with the silicone 5, it may be applied directly to the electrical connection portion B18, or may be indirectly poured into the electrical connection portion B18 by inserting an appropriate amount into the tube.
以下、固定子巻線２同士の接続方法について、詳細に説明する。まず、図８に示す通り、電気接続部Ｂ１８において、固定子巻線２の導体（アルミニウム系材料）同士を、端子１（銅系材料）によって圧着することにより、電気的に接続する。ここで、電気接続部Ｂ１８は異種金属による接続となるため、このままだと、接続部に水分が付着した場合に、端子１と固定子巻線２の導体に異種金属の接触腐食が生じる。 Hereinafter, a method for connecting the stator windings 2 will be described in detail. First, as shown in FIG. 8, in the electrical connection portion B <b> 18, the conductors (aluminum-based material) of the stator winding 2 are electrically connected to each other by crimping with the terminal 1 (copper-based material). Here, since the electrical connection portion B18 is connected by a dissimilar metal, if moisture remains attached to the connection portion, contact corrosion of the dissimilar metal occurs in the conductors of the terminal 1 and the stator winding 2.
そこで、シリコーン５を電気接続部Ｂ１８に塗布した後、図９のように、その周囲に熱収縮チューブ６を被せる。次に、熱収縮チューブ６を加熱して収縮させることにより、熱収縮チューブ６がシリコーン５と固着する。このとき、熱収縮チューブ６内の余分なシリコーン５は、熱収縮チューブ６内の隙間を埋めながら両端に移動し、図１０に示すような状態となる。 Therefore, after the silicone 5 is applied to the electrical connection portion B18, the heat shrinkable tube 6 is placed around the periphery as shown in FIG. Next, the heat-shrinkable tube 6 adheres to the silicone 5 by heating and shrinking the heat-shrinkable tube 6. At this time, excess silicone 5 in the heat-shrinkable tube 6 moves to both ends while filling the gap in the heat-shrinkable tube 6, and a state as shown in FIG. 10 is obtained.
結果として、電気接続部Ｂ１８の両端からの水の浸入経路が塞がれ、外部から水分が浸入するのを防止でき、長期的に防食効果を維持することが可能となる。この一連の作業は、固定子７の製造工程上で作業できるので量産体制に影響を及ぼさない。 As a result, the water intrusion path from both ends of the electrical connection portion B18 is blocked, moisture can be prevented from entering from the outside, and the anticorrosion effect can be maintained for a long time. Since this series of operations can be performed in the manufacturing process of the stator 7, it does not affect the mass production system.
次に、固定子巻線２同士の別の接続方法を説明する。 Next, another method for connecting the stator windings 2 will be described.
作業方法としては、先に、熱収縮チューブ６の一端側を収縮させておき、熱収縮チューブ６の他端側からシリコーン５を適量注入する。その後、固定子巻線２の導体同士が端子１によって圧着された、図８に示す状態の電気接続部Ｂ１８を、熱収縮チューブ６内に挿入する。そして、図９の状態で熱収縮チューブ６に熱を加えると、熱収縮チューブ６が収縮してシリコーン５と固着し、最終的に図１０の状態になる。 As a working method, first, one end side of the heat shrinkable tube 6 is contracted, and an appropriate amount of silicone 5 is injected from the other end side of the heat shrinkable tube 6. Thereafter, the electrical connection portion B18 in the state shown in FIG. 8 in which the conductors of the stator winding 2 are crimped by the terminals 1 is inserted into the heat shrinkable tube 6. Then, when heat is applied to the heat-shrinkable tube 6 in the state shown in FIG. 9, the heat-shrinkable tube 6 shrinks and adheres to the silicone 5 and finally becomes the state shown in FIG.
また、電気接続部Ｂ１８の固定子巻線２同士の導体の材質の組合せは、アルミニウム系材料とアルミニウム系材料、アルミニウム系材料と銅系材料の組合が考えられる。導体本数は３本以上でも良く、組合せはアルミニウム系材料とアルミニウム系材料、アルミニウム系材料と銅系材料の組合せになる。 Moreover, the combination of the material of the conductors of the stator windings 2 of the electrical connection portion B18 may be a combination of an aluminum-based material and an aluminum-based material, or an aluminum-based material and a copper-based material. The number of conductors may be three or more, and the combination is a combination of an aluminum-based material and an aluminum-based material, and an aluminum-based material and a copper-based material.
上述した実施例１及び実施例２によれば、回転電機１４の固定子巻線１２をアルミニウム系材料とすることで、従来のように銅系材料を用いた場合と比べて、洗濯乾燥機を全体として軽量化が可能となるだけでなく、低コスト化も実現できる。ここで、アルミニウム系材料とは、アルミニウムだけでなくアルミニウム合金を含むものとし、銅系材料とは、銅だけでなく銅合金を含むものとする。 According to the first embodiment and the second embodiment described above, the stator winding 12 of the rotating electrical machine 14 is made of an aluminum-based material, so that the washing / drying machine can be used as compared with the conventional case of using a copper-based material. Not only can the weight be reduced as a whole, but also the cost can be reduced. Here, the aluminum-based material includes not only aluminum but also an aluminum alloy, and the copper-based material includes not only copper but also a copper alloy.
なお、上述の実施例１及び実施例２では、収縮可能なチューブとして熱収縮チューブ６を用いたが、熱以外の変化を加えることで収縮する他のチューブを用いても構わない。 In the first and second embodiments described above, the heat-shrinkable tube 6 is used as a shrinkable tube, but other tubes that shrink by applying a change other than heat may be used.
更に、上述の実施例では、回転電機１４を洗濯乾燥機に用いた例を説明したが、これに限らず、ポンプや家庭用・産業用機器に使用しても良い。 Furthermore, although the example which used the rotary electric machine 14 for the washing-drying machine was demonstrated in the above-mentioned Example, you may use for not only this but a pump and household / industrial equipment.
