Description

この発明は、電動機の固定子に関するもので、特にリード線を配線するリード線配線部品に関するものである。また、その電動機の固定子を用いる電動機及び電動機の製造方法に関する。さらに、その電動機を搭載する空気調和機に関する。   The present invention relates to a stator of an electric motor, and more particularly to a lead wire wiring component for wiring lead wires. The present invention also relates to a motor using the stator of the motor and a method for manufacturing the motor. Furthermore, it is related with the air conditioner which mounts the electric motor.

An electric motor provided with a lead wire fixing means has been proposed (see, for example, Patent Document 1).
また、電源リード線を直接コイルと結線する電動機の固定子において、回転子の回転検出センサーを低価格で簡単に取付けができるようにするために、固定子鉄心と、この固定子鉄心に絶縁部を介して施した巻線とを有する固定子と、この固定子に内装された回転子と、巻線に電力を供給するための電源リード線と、固定子に設けられ、電源リード線を保持する電源リード線保持手段と、回転子の回転を検出し、センサーリード線が接続された回転検出センサーを取付けた基板と、センサーリード線を押さえるリード線押さえ手段と、中仕切り部品と、を備え、センサーリード線はリード線押さえ手段と中仕切り部品とで、また、電源リード線は中仕切り部品と電源リード線保持手段とで挟み込まれて軸方向に2段に組立られる構成とした電動機の固定子が提案されている(例えば、特許文献2参照)。   In addition, in the stator of an electric motor in which the power supply lead wire is directly connected to the coil, in order to make it easy to install the rotation detection sensor of the rotor at a low cost, the stator core and an insulating part on the stator core A stator having a winding provided through the stator, a rotor embedded in the stator, a power supply lead wire for supplying power to the winding, and a stator provided to hold the power supply lead wire Power supply lead wire holding means, a substrate mounted with a rotation detection sensor to detect rotation of the rotor and connected to the sensor lead wire, a lead wire holding means for holding the sensor lead wire, and a partition part.

本実施の形態の電動機の固定子100は、例えば、電動機がブラシレスDCモータの固定子である。電動機の用途は、例えば、送風機用電動機等である。電動機として、固定子のスロット数(ティース数)が9で、回転子の極数が8極ものを例に説明する。当然ではあるが、この仕様の電動機に限定されるものではない。スロット数、極数は問わない。   In the electric motor stator 100 of the present embodiment, for example, the electric motor is a stator of a brushless DC motor. The use of the electric motor is, for example, a blower motor. As an electric motor, an example in which the number of stator slots (number of teeth) is 9 and the number of rotor poles is 8 will be described. Of course, the motor is not limited to this specification. The number of slots and the number of poles do not matter.
図1、図2に示すように、電動機の固定子100は、固定子組立50と、リード線配線部品組立200とを備える。   As shown in FIGS. 1 and 2, the stator 100 of the electric motor includes a stator assembly 50 and a lead wire wiring component assembly 200.
先ず、図3により、固定子組立50の構成を説明する。図3に示すように、固定子組立50は、固定子鉄心51と、固定子鉄心51のティースに絶縁部52を介して巻回されるコイル54とを備える。   First, the configuration of the stator assembly 50 will be described with reference to FIG. As shown in FIG. 3, the stator assembly 50 includes a stator core 51 and a coil 54 wound around the teeth of the stator core 51 via an insulating portion 52.
電動機の固定子100は、インナーロータ形の電動機の固定子である。図示しない回転子(ロータ)が、電動機の固定子100の内部に挿入されて回転する。   The electric motor stator 100 is an inner rotor type electric motor stator. A rotor (rotor) (not shown) is inserted into the stator 100 of the electric motor and rotates.
固定子鉄心51は、電磁鋼板が帯状に所定の形状に打ち抜かれ、所定の枚数をかしめ(一般的である)、溶接、接着等で積層されて形成される。本実施の形態の固定子鉄心51は、コアバック56から略直角に延びる9個のティース57を有する。   The stator core 51 is formed by punching a magnetic steel sheet into a predetermined shape in a band shape, and laminating a predetermined number of sheets (generally), welding, adhesion, or the like. The stator core 51 of the present embodiment has nine teeth 57 extending from the core back 56 at a substantially right angle.
巻線が完了して固定子鉄心51を略円筒形に曲げた固定子組立50では、9個のティース57は円筒形状のコアバック56の内周から中心に向かって放射状に延びる。図3では、ティース57の先端部(図示しない回転子に対向する部分)が見えているが、その他の部分は、コイル54と絶縁部52とに隠れて見えていない。但し、ティース57の数は、9個に限定されるものではない。   In the stator assembly 50 in which the winding is completed and the stator core 51 is bent into a substantially cylindrical shape, the nine teeth 57 extend radially from the inner periphery of the cylindrical core back 56 toward the center. In FIG. 3, the tip portion of the tooth 57 (the portion facing the rotor (not shown)) is visible, but the other portion is hidden behind the coil 54 and the insulating portion 52 and is not visible. However, the number of teeth 57 is not limited to nine.
帯状の固定子鉄心51の9個のティース57に、例えば、PBT(ポリブチレンテレフタレート)等の熱可塑性樹脂を一体に成形して絶縁部52が形成される。但し、熱可塑性樹脂で成形した絶縁部52をティース57に組付けるようにしてもよい。   For example, a thermoplastic resin such as PBT (polybutylene terephthalate) is integrally formed on the nine teeth 57 of the belt-shaped stator core 51 to form the insulating portion 52. However, you may make it assemble the insulation part 52 shape | molded with the thermoplastic resin to the teeth 57. FIG.
各ティース57は、図示しない回転子に対向するティース57の先端部を除いて、絶縁部52で覆われる。回転子に対向するティース57の先端部と回転子の外周面との間は、所定の径方向寸法の空隙となる。電動機の効率は、空隙の径方向寸法と密接な関係があり、空隙の径方向寸法は極力小さい方が好ましい。そのため、ティース57の先端部は絶縁部52で覆わずに露出させる。   Each tooth 57 is covered with an insulating portion 52 except for a tip portion of the tooth 57 facing a rotor (not shown). A gap having a predetermined radial dimension is formed between the tip of the teeth 57 facing the rotor and the outer peripheral surface of the rotor. The efficiency of the electric motor is closely related to the radial dimension of the gap, and it is preferable that the radial dimension of the gap is as small as possible. Therefore, the tip portion of the teeth 57 is exposed without being covered with the insulating portion 52.
ティース57に絶縁部52を施した後、帯状の固定子鉄心51を逆曲げして巻線しやすい形状にする。帯状の固定子鉄心51を逆曲げすると、コアバック56が内側になり、ティース57がコアバック56の外側に位置する。そして、この状態は、隣接するティース57の先端の間が帯状のときよりも広くなるので、巻線がしやすくなる。   After the insulating portion 52 is applied to the teeth 57, the strip-shaped stator core 51 is reversely bent so as to be easily wound. When the belt-shaped stator iron core 51 is reversely bent, the core back 56 is located inside, and the teeth 57 are located outside the core back 56. In this state, the gap between the tips of the adjacent teeth 57 is wider than when the band 57 is formed, so that the winding is easy.
固定子鉄心51を逆曲げした状態で、マグネットワイヤーを各ティース57に巻きつけてコイル54を形成する。   In a state where the stator iron core 51 is reversely bent, a coil 54 is formed by winding a magnet wire around each tooth 57.
例えば、コイル54は、三相の巻線であり、Y結線(三相各相をその一端の中性点で接続する結線で、星形結線、スター結線とも呼ばれる)の三相巻線を形成する。   For example, the coil 54 is a three-phase winding, and forms a three-phase winding of a Y connection (a connection connecting each phase of the three phases at a neutral point at one end thereof, also called a star connection or a star connection). To do.
ここで、本実施の形態の固定子組立50の巻線について説明する。9スロット・8極の三相巻線を形成するには、例えば、図3に示すように、U相の3個のコイル54(u1、u2、u3)を連続する3個のティース57に巻線する。このときの巻き方向は、u1とu3とが同じでu2がそれらと反対方向に巻かれる。   Here, the winding of the stator assembly 50 of the present embodiment will be described. To form a 9-slot, 8-pole three-phase winding, for example, as shown in FIG. 3, three U-phase coils 54 (u1, u2, u3) are wound around three teeth 57. To line. As for the winding direction at this time, u1 and u3 are the same, and u2 is wound in the opposite direction.
このとき、U相のマグネットワイヤーの一方の端末は、第1の電源端子55a−1のフック部58に引き回され、ヒュージング(一般的)、あるいは半田等でフック部58に接合される。尚、第1の電源端子55a−1は、この状態では、2個のフック部58のうちの1個を使用し、他の1個は空いている。他の端子についても、同様にフック部58を2個備える(図5、図6参照)。   At this time, one end of the U-phase magnet wire is drawn around the hook portion 58 of the first power supply terminal 55a-1 and joined to the hook portion 58 by fusing (general) or solder.

口出し部11の左側の被覆端末保持部13から内周壁17の外側に沿って口出し部11まで引き回され、第1の折り返し部25で略直角に折り返されて、突起28と側壁29との間の第1の電源リード線保持部27−1に保持されて電源リード線用溝32から外部に引き出される。   From the coated terminal holding part 13 on the left side of the lead part 11, the lead part 11 is routed along the outside of the inner peripheral wall 17 to the lead part 11, and is folded at a substantially right angle by the first folding part 25. Is held by the first power supply lead wire holding portion 27-1 and pulled out from the power supply lead wire groove 32.
第1の折り返し部25も、上部に位置ずれ防止突起25aを有する。   The first folded portion 25 also has a misalignment prevention protrusion 25a on the top.
電源リード線70(3本)の口出し部11への仮固定が完了したら、電源リード線保持部品71を一対の第2の係り止め部22に係り止めて電源リード線70を固定する。電源リード線をリード線配線部品に固定した後に、基板をリード線配線部品の一対の組付け足81aと一対の組付け足81bに組付け、センサーリード線に備えたボードイン形コネクタ90を基板に半田付けして接合する。   When the temporary fixing of the power supply lead wires 70 (three) to the lead-out portion 11 is completed, the power supply lead wire holding component 71 is locked to the pair of second locking portions 22 to fix the power supply lead wire 70.

Solder to and join.
センサーリード線60の配線は、中央の3本が保持突起23の間に軽く保持される(図14参照)。また、両端の2本のセンサーリード線60は、保持突起23と、電源リード線保持部品71の突起71b(図18参照)の内側との間に軽く保持される。電源リード線保持部品の突起71bでセンサーリード線を軽く保持する構造とすることで、電源リード線保持部品を小さくすることが出来るため、コストの低減が図れる。
センサーリード線は、センサーリード線保持部品61を一対の第1の係り止め部21に係り止めて固定する。
The three sensor lead wires 60 are lightly held between the holding projections 23 (see FIG. 14). Further, the two sensor lead wires 60 at both ends are lightly held between the holding projection 23 and the inside of the projection 71b (see FIG. 18) of the power supply lead wire holding component 71. By adopting a structure in which the sensor lead wire is lightly held by the projection 71b of the power supply lead wire holding component, the power supply lead wire holding component can be made small, so that the cost can be reduced.
The sensor lead wire engages and fixes the sensor lead wire holding component 61 to the pair of first anchor portions 21.
図18に示すように、電源リード線保持部品71は、既に述べた突起71b(口出し方向に略直角方向に形成される)を有する一対の足71a(口出し部11への設置面71fより直角に延びる)以外に、口出し部11へ組付けた状態でリード線配線部品10の中心側(内側)に延びる一対のリブ71cと、この一対のリブ71cを連結する連結部71dとを備える。   As shown in FIG. 18, the power supply lead wire holding component 71 has a pair of legs 71 a (which are formed in a direction substantially perpendicular to the lead-out direction) described above at a right angle from the installation surface 71 f on the lead-out portion 11. In addition to a pair of ribs 71c extending to the center side (inner side) of the lead wire wiring component 10 in a state assembled to the lead portion 11, and a connecting portion 71d for connecting the pair of ribs 71c.
図7に示すように、電源リード線保持部品71を口出し部11へ組付けた状態では、リブ71cがリード線配線部品を押えるので、口出し部11の外側端部における電源リード線70の軸方向に開くガタを減らすことができる。   As shown in FIG. 7, in the state where the power supply lead wire holding component 71 is assembled to the lead portion 11, the rib 71 c presses the lead wire wiring component, so the axial direction of the power lead wire 70 at the outer end portion of the lead portion 11 Can reduce the amount of backlash.
図17に示すように、センサーリード線保持部品61は、センサーリード線60を納める溝61bを有する。   As shown in FIG. 17, the sensor lead wire holding component 61 has a groove 61 b for receiving the sensor lead wire 60.

以上でリード線配線部品組立200の組立が完了する。尚、口出し部11から外部へ引き出されたセンサーリード線60(5本)及び電源リード線70(3本)の処理については、本実施の形態の主要な特徴に関係しないので、説明は省く。   Thus, the assembly of the lead wire wiring component assembly 200 is completed. Note that the processing of the sensor lead wires 60 (5 wires) and the power supply lead wires 70 (3 wires) drawn out from the lead-out portion 11 is not related to the main features of the present embodiment, and will not be described.
次に、リード線配線部品組立200の固定子組立50への組付けについて説明する。   Next, assembly of the lead wire wiring component assembly 200 to the stator assembly 50 will be described.
図1、図2に示すように、リード線配線部品10の取付足12の穴12aに固定子組立50の絶縁部52のピン53を挿入して、リード線配線部品組立200を固定子組立50へ組付ける。   As shown in FIGS. 1 and 2, the pin 53 of the insulating portion 52 of the stator assembly 50 is inserted into the hole 12 a of the mounting leg 12 of the lead wire wiring component 10, and the lead wire wiring component assembly 200 is fixed to the stator assembly 50. Assemble.
このとき、リード線配線部品10の取付足12が絶縁部52の設置面52aに当接して、リード線配線部品10の軸方向の位置決めがなされる。また、絶縁部52のピン53が、リード線配線部品10の取付足12の穴12aに挿入されることで、リード線配線部品10の回転方向の位置決めがなされる。   At this time, the mounting legs 12 of the lead wire wiring component 10 abut on the installation surface 52a of the insulating portion 52, and the lead wire wiring component 10 is positioned in the axial direction. Further, the pin 53 of the insulating portion 52 is inserted into the hole 12 a of the mounting leg 12 of the lead wire wiring component 10, whereby the lead wire wiring component 10 is positioned in the rotational direction.
リード線配線部品10の取付足12の穴12aに固定子組立50の絶縁部52のピン53を挿入後、穴12aから突出するピン53を、熱溶着、超音波溶着等で固定する(図19)。   After inserting the pin 53 of the insulating portion 52 of the stator assembly 50 into the hole 12a of the mounting leg 12 of the lead wire wiring component 10, the pin 53 protruding from the hole 12a is fixed by heat welding, ultrasonic welding, or the like (FIG. 19). ).
固定子組立50にリード線配線部品10が組付けられた後に、電源リード線70の芯線70aと端子55とをスポット溶接して、電源リード線70と端子55とを接続する(図20)。   After the lead wire wiring component 10 is assembled to the stator assembly 50, the core wire 70a of the power supply lead wire 70 and the terminal 55 are spot welded to connect the power supply lead wire 70 and the terminal 55 (FIG. 20).
このとき、端子55と芯線70aとを挟み込む電極(リード線配線部品10の内側に配置される電極)の空間確保ために、リード線配線部品10に電極逃がし用の凹部14(図1、図2、図6、図9)を設ける。   At this time, in order to secure a space for an electrode (electrode disposed inside the lead wire wiring component 10) sandwiching the terminal 55 and the core wire 70a, the lead wire wiring component 10 has an electrode escape recess 14 (FIGS. 1 and 2). 6 and 9).
また、電極逃がし用の凹部14を設けることで、電源リード線70はリード線配線部品10のリード線配線面16a(図10)よりもさらに固定子組立50側に引回され(固定子組立50側に張り出す)、且つ位置ずれ防止突起17aを電極逃がし用の凹部14(電源リード線70が裏側を通る凹部14、例えば図8の口出し部11の右側の凹部14)の両側に設けることで、電源リード線70は凹部14の裏側と、凹部14の両側の位置ずれ防止突起17aとの間に挟まれて強固に固定されて軸方向の位置決めがなされる。   Further, by providing the electrode escape recess 14, the power supply lead wire 70 is further routed to the stator assembly 50 side than the lead wire wiring surface 16 a (FIG. 10) of the lead wire wiring component 10 (stator assembly 50). The projections 17a are provided on both sides of the electrode escape recess 14 (the recess 14 through which the power supply lead wire 70 passes through the back side, for example, the recess 14 on the right side of the lead 11 in FIG. 8). The power lead 70 is sandwiched between the back side of the recess 14 and the misalignment prevention protrusions 17a on both sides of the recess 14 and is firmly fixed to be positioned in the axial direction.
以上のように、電源リード線70をリード線配線部品10の固定子組立50側の面に引き回し、センサーリード線60をリード線配線部品10の反固定子組立50側の面に引き回すので、リード線配線部品組立200の組立が容易となりコストの低減が図れる。また、リード線配線部品組立200の組立が容易になることに伴い品質の向上が図れる。   As described above, the power supply lead wire 70 is routed to the surface of the lead wire wiring component 10 on the stator assembly 50 side, and the sensor lead wire 60 is routed to the surface of the lead wire wiring component 10 on the side opposite to the stator assembly 50. Assembly of the line wiring component assembly 200 is facilitated, and costs can be reduced. Further, quality can be improved as the assembly of the lead wire wiring component assembly 200 becomes easier.
また、電源リード線70を位置ずれ防止突起17aで保持して軸方向の位置ずれを防止することで、品質の向上が図れる。   Further, the power lead 70 is held by the misalignment prevention protrusion 17a to prevent the misalignment in the axial direction, so that the quality can be improved.
また、リード線配線部品10の口出し部11に、第1の係り止め部21及び第2の係り止め部22を備えることで、電源リード線70を電源リード線保持部品71で保持し、センサーリード線60をセンサーリード線保持部品61で保持するので、電源リード線70及びセンサーリード線60をリード線配線部品10に強固に組み付けが可能となり、組立て状態の信頼性向上に伴う品質の向上が図れる。   Further, the lead wire wiring component 10 includes the first locking portion 21 and the second locking portion 22 in the lead portion 11 so that the power lead 70 is held by the power lead holding component 71 and the sensor lead. Since the wire 60 is held by the sensor lead wire holding component 61, the power supply lead wire 70 and the sensor lead wire 60 can be firmly assembled to the lead wire wiring component 10, and the quality can be improved as the reliability of the assembled state is improved. .
さらに、電源リード線保持部品71の足71aの突起71bをセンサーリード線60の保持にも使用することで、組立てが容易となりコストの低減が図れる。また、組立が容易になることに伴い品質の向上が図れる。   Furthermore, by using the protrusion 71b of the foot 71a of the power supply lead wire holding component 71 also for holding the sensor lead wire 60, the assembly can be facilitated and the cost can be reduced. Further, the quality can be improved as the assembly becomes easier.
