That is, the neutral wire 30a on the winding start side of the tooth winding portion 11a serving as the second magnetic pole portion U2 and the neutral wire 30b on the winding end side of the teeth winding portion 11b serving as the first magnetic pole portion U1 are neutralized. Connection is made via point N. The other V-phase winding 4b and W-phase winding 4c are wound in the same manner as the U-phase winding 4a. For this reason, the second magnetic pole portions U2, V2, W2 of the windings 4a, 4b, 4c each have a single extraction portion 32... Drawn to the first magnetic pole portions U1, V1, W1, and the first magnetic pole portion U1. , V1 and W1 have a lead-out portion 33 that is led out to the neutral wire 30 (30b).
そして、上記電源線２９を、ティース巻回部１１とスロット底部２１（スロット１５の内周面）との間に挟むようにして固定している。すなわち、図５に示すように、第２磁極部Ｕ２を構成するティース巻回部１１ｂと、これに対応するスロット底部２１とでこの電源線２９を挟持するようにしている。 The power supply line 29 is fixed so as to be sandwiched between the tooth winding part 11 and the slot bottom part 21 (inner peripheral surface of the slot 15). That is, as shown in FIG. 5, the power supply line 29 is sandwiched between the tooth winding part 11b constituting the second magnetic pole part U2 and the slot bottom part 21 corresponding thereto.
次に、インシュレータ５の外周壁部８は、図３に示すように各スロット１５に対応した分割壁１６・・を備え、第１スロット１５ａには第１分割壁１６ａが対応し、第２スロット１５ｂには第２分割壁１６ｂが対応し、第３スロット１５ｃには第３分割壁１６ｃが対応し、第４スロット１５ｄには第４分割壁１６ｄが対応し、第５スロット１５ｅには第５分割壁１６ｅが対応し、第６スロット１５ｆには第６分割壁１６ｆが対応する。そして、分割壁１６・・にスリット２４を設け、このスリット２４に電源線２９を係止させている。すなわち、第１分割壁１６ａにおいて、スリット２４を設けることによって、この第１分割壁１６ａを、第１壁部２２と第２壁部２３とに分割し、第６分割壁１６ｆの内面に沿って引出される電源線２９を、第１分割壁１６ａの第１壁部２２においてはこの第１壁部２２の内面側に配置し、第１分割壁１６ａの第２壁部２３においてはこの第２壁部２３の外面側に配置する。この分割壁１６・・は後述する受け部を構成する。 Next, as shown in FIG. 3, the outer peripheral wall portion 8 of the insulator 5 is provided with dividing walls 16 corresponding to the slots 15, the first dividing wall 16a corresponds to the first slot 15a, and the second slot 15b corresponds to the second dividing wall 16b, the third slot 15c corresponds to the third dividing wall 16c, the fourth slot 15d corresponds to the fourth dividing wall 16d, and the fifth slot 15e corresponds to the fifth slot. The dividing wall 16e corresponds, and the sixth dividing wall 16f corresponds to the sixth slot 15f. A slit 24 is provided in the dividing wall 16..., And a power line 29 is engaged with the slit 24. That is, by providing the slit 24 in the first dividing wall 16a, the first dividing wall 16a is divided into the first wall portion 22 and the second wall portion 23, and along the inner surface of the sixth dividing wall 16f. The drawn power line 29 is arranged on the inner surface side of the first wall portion 22 in the first wall portion 22 of the first divided wall 16a, and the second wall portion 23 of the first divided wall 16a. It arrange | positions at the outer surface side of the wall part 23. FIG. The dividing walls 16... Constitute a receiving portion described later.
この場合、第６分割壁１６ｆと第１分割壁１６ａとの間には、電源線２９を支持する巻線離隔部２５（２５ａ）を設け、第１分割壁１６ａと第２分割壁１６ｂとの間には、電源線２９を支持する巻線離隔部２５（２５ｂ）を設け、第２分割壁１６ｂと第３分割壁１６ｃとの間には、電源線２９を支持する巻線離隔部２５（２５ｃ）を設けている。すなわち、第６分割壁１６ｆと第１分割壁１６ａとの間の溝２６に隆起部を設けることによって、巻線離隔部２５ａを形成し、第１分割壁１６ａと第２分割壁１６ｂとの間の溝２７に隆起部を設けることによって、巻線離隔部２５ｂを形成し、第２分割壁１６ｂと第３分割壁１６ｃとの間の溝２８に隆起部を設けることによって、巻線離隔部２５ｃを形成している。 In this case, a winding separation portion 25 (25a) for supporting the power supply line 29 is provided between the sixth dividing wall 16f and the first dividing wall 16a, and the first dividing wall 16a and the second dividing wall 16b are separated from each other. A winding separation part 25 (25b) for supporting the power supply line 29 is provided between them, and a winding separation part 25 (for supporting the power supply line 29) is provided between the second division wall 16b and the third division wall 16c. 25c). That is, by providing a raised portion in the groove 26 between the sixth dividing wall 16f and the first dividing wall 16a, the winding separation portion 25a is formed, and between the first dividing wall 16a and the second dividing wall 16b. A winding separation portion 25b is formed by providing a raised portion in the groove 27, and a winding separation portion 25c is formed by providing a protruding portion in the groove 28 between the second divided wall 16b and the third divided wall 16c. Is forming.
このため、電源線２９は巻線離隔部２５ａ、２５ｂ、２５ｃを通過することになって、これらの巻線離隔部２５ａ、２５ｂ、２５ｃにて、中性線３０側への移動が規制されている。このため、インシュレータ５の外周壁部８の外面側に配設される中性線３０との電源線２９の接触を防止した状態でリード線２０（各Ｕ相、Ｖ相、Ｗ相の電源線２９・・が束ねられてなる）を引出すことができる。なお、反リード線側のインシュレータ５ｂも、各スロット１５に対応した分割壁１７・・を備えているが、この分割壁１７には巻線離隔部２５（２５ａ、２５ｂ、２５ｃ）等を設けていない。これは、反リード線側のインシュレータ５ｂ側に電源線２９が引出されないからである。 For this reason, the power supply line 29 passes through the winding separation portions 25a, 25b, and 25c, and movement to the neutral wire 30 side is restricted by these winding separation portions 25a, 25b, and 25c. Yes. For this reason, the lead wire 20 (each U-phase, V-phase, W-phase power wire) in a state in which the contact of the power wire 29 with the neutral wire 30 disposed on the outer surface side of the outer peripheral wall portion 8 of the insulator 5 is prevented. 29 .... are bundled). The insulator 5b on the side opposite to the lead wire also includes a dividing wall 17 corresponding to each slot 15, and the dividing wall 17 is provided with a winding separation portion 25 (25a, 25b, 25c) and the like. Absent. This is because the power supply line 29 is not drawn out to the insulator 5b side on the opposite lead wire side.
ところで、インシュレータ５の各分割壁１６・・は、固定子コア３の端面からはみだしたティース巻回部１１のはみ出し部３５（図１参照）を外方側から受ける受け部を構成する。すなわち、各分割壁（受け部）１６は、その高さ寸法（軸心方向長さ）Ｈ（図３参照）がティース巻回部１１のはみ出し部３５の突出寸法と略同一またはこの突出寸法よりも僅かに大きく設定され、さらにその周方向長さ（図３参照）Ｓが、周方向に隣合うティース巻回部１１、１１の周方向端部に対応する長さに設定される。 By the way, each partition wall 16 ... of the insulator 5 comprises the receiving part which receives the protrusion part 35 (refer FIG. 1) of the teeth winding part 11 which protruded from the end surface of the stator core 3 from the outer side. That is, each dividing wall (receiving portion) 16 has a height dimension (length in the axial direction) H (see FIG. 3) substantially the same as the protruding dimension of the protruding portion 35 of the tooth winding part 11 or from this protruding dimension. Is set slightly larger, and the circumferential length (see FIG. 3) S is set to a length corresponding to the circumferential ends of the teeth winding portions 11 and 11 adjacent to each other in the circumferential direction.
ところで、この電動機（永久磁石型電動機）は、例えば、空気調和装置の圧縮機の電動機に使用するものである。圧縮機は、ケーシング（密閉容器）と、この密閉容器の下部側に収納される圧縮機要素部と、この密閉容器の上部側に収納される電動機要素部とを備え、この電動機要素部に上記永久磁石型電動機が使用される。このため、回転子２の軸心孔に挿入固定されるシャフトは、上記圧縮機要素部のクランク軸であり、このクランク軸が密閉容器内の支持部材に支持される。 By the way, this electric motor (permanent magnet type electric motor) is used for an electric motor of a compressor of an air conditioner, for example. The compressor includes a casing (closed container), a compressor element portion housed on the lower side of the hermetic container, and an electric motor element portion housed on the upper side of the hermetic container. A permanent magnet type motor is used. For this reason, the shaft inserted and fixed in the shaft hole of the rotor 2 is the crankshaft of the compressor element portion, and this crankshaft is supported by the support member in the hermetic container.
上記電動機の固定子では、巻線４のティース巻回部１１から引出される電源線２９を、ティース巻回部１１とスロット底部２１との間に挟んで固定したので、電源線２９をふらつかせることなく、巻設することがことができる。このため、この電源線２９が他の相のティース巻回部１１に接触するのを防止することができ、長期に渡って電動機として安定した機能を発揮することができる。また、従来において使用していた保護チューブ等を省略することが可能となって、組立性向上及びコスト低減に図ることができる。さらに、電源線２９を固定するための複雑な構成を必要とせず、構造の簡略化を図って、コスト低減化を一層図ることができる。 In the stator of the electric motor, the power supply line 29 drawn from the tooth winding part 11 of the winding 4 is sandwiched and fixed between the tooth winding part 11 and the slot bottom part 21, so that the power supply line 29 can be staggered. It can be wound without any problems. For this reason, it can prevent that this power wire 29 contacts the tooth winding part 11 of another phase, and can exhibit the stable function as an electric motor over a long period of time. Moreover, it becomes possible to omit the protective tube etc. which were used conventionally, and it can aim at the assembly property improvement and cost reduction. Furthermore, a complicated configuration for fixing the power supply line 29 is not required, the structure can be simplified, and the cost can be further reduced.
また、インシュレータ５に、電源線２９と中性線３０との間を所定間隔に維持する巻線離隔部２５を設けたので、電源線２９が中性線３０に接触することを防止することができる。これにより、高品質の電動機を提供することができる。しかも、配線作業において電源線２９が中性線３０に接触しないように確実に配線することができ、巻線４の配線作業の簡略化を図ることができる。すなわち、インシュレータ５に巻線離隔部２５を設けたことにより、安定した配線作業性を達成できると共に、電源線２９と中性性３０との非接触性の信頼性の向上を図ることができる。さらに、インシュレータ５は、外周側には外周壁部８の分割壁１６にて構成される受け部を有するので、ティース巻回部１１のはみ出し部３５の外方向への倒れがこの受け部１６にて防止され、各ティース巻回部１１は安定した巻設（巻回）状態を維持することができ、巻設作業の簡略化を達成できると共に、高品質の固定子を提供することができる。また、インシュレータ５の内周側には立上片部１０・・を有しているので、ティース巻回部１１のはみ出し部３５の内方への倒れも防止できる。 In addition, since the insulator 5 is provided with the winding separation portion 25 that maintains a predetermined distance between the power supply line 29 and the neutral line 30, it is possible to prevent the power supply line 29 from contacting the neutral line 30. it can. Thereby, a high quality electric motor can be provided. In addition, it is possible to reliably wire the power supply line 29 so that it does not come into contact with the neutral wire 30 in the wiring work, and to simplify the wiring work of the winding 4. That is, by providing the insulator 5 with the winding separation portion 25, stable wiring workability can be achieved, and the reliability of non-contact between the power supply line 29 and the neutral 30 can be improved. Furthermore, since the insulator 5 has a receiving portion constituted by the dividing wall 16 of the outer peripheral wall portion 8 on the outer peripheral side, the outward protrusion of the protruding portion 35 of the tooth winding portion 11 is caused to the receiving portion 16. Each of the teeth winding sections 11 can maintain a stable winding (winding) state, simplify the winding work, and provide a high-quality stator. Moreover, since the rising piece 10 is provided on the inner peripheral side of the insulator 5, it is possible to prevent the protrusion 35 of the teeth winding part 11 from falling inward.
以上にこの発明の具体的な実施の形態について説明したが、この発明は上記形態に限定されるものではなく、この発明の範囲内で種々変更して実施することができる。例えば、電動機としての相数及び極数の変更が可能である。また、電源線２９と中性線３０との所定間隔としては、電源線２９と中性線３０とが接触しない範囲で、巻線離隔部２５ａ、２５ｂ、２５ｃを構成する各膨出部の高さ寸法を任意に変更することによって相違させることができ、また、各膨出部の高さ寸法としても同一であっても相違するものであってもよい。 Although specific embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the present invention. For example, the number of phases and the number of poles as an electric motor can be changed. Further, the predetermined interval between the power supply line 29 and the neutral wire 30 is within a range where the power supply line 29 and the neutral wire 30 do not contact with each other, and the height of each bulging portion constituting the winding separation portions 25a, 25b, 25c It can be made different by arbitrarily changing the height dimension, and the height dimension of each bulging part may be the same or different.
