Ru.

図７は、内側第１異形セグメント導体３３ａの外観図である。図７に示すように、内側第１異形セグメント導体３３ａは、所定の間隔（標準セグメント導体３１における間隔と同じ間隔）にあるスロット内に配置される一対の直線部３３１と、固定子４０の軸方向におけるステータコア９の一方の片側にあり、頭部３３２ａを有する折り曲げ部３３３ａと、ステータコア９の他方の片側に形成される一対の端末部３３４とを有する。一対の端末部３３４の図示点線は、内側第１異形セグメント導体３３ａを端末部３３４の先端からスロット内へ挿入するために直線形状になっているが、スロットへ挿入後に曲げ成形されて標準セグメント導体３１の端末部３１４と接続される。 FIG. 7 is an external view of the inner first irregularly shaped segment conductor 33a. As shown in FIG. 7, the inner first deformed segment conductor 33a has a pair of straight portions 331 arranged in slots at a predetermined interval (same interval as the standard segment conductor 31), and an axis of the stator 40. The bending portion 333a is located on one side of the stator core 9 in the direction, and has a bent portion 333a having a head 332a, and a pair of terminal portions 334 formed on the other side of the stator core 9. The illustrated dotted lines of the pair of terminal parts 334 are linear in order to insert the inner first irregularly shaped segment conductor 33a into the slot from the tip of the terminal part 334, but after being inserted into the slot, it is bent and formed into a standard segment conductor. It is connected to the terminal unit 314 of No. 31.

内側第１異形セグメント導体３３ａは、図３に示すように、内側第１異形セグメント導体３３ａの頭部３３２ａが標準セグメント導体３１の頭部３１２の上に存在しており、標準セグメント導体３１の頭部３１２を複数跨ぐ直線状となっている。仮に、この内側第１異形セグメント導体３３ａのみをステータコア９に組み込んだ場合は、複数の内側第１異形セグメント導体３３ａを近傍に配置すると、その頭部３３２ａが互いに干渉してしまう。このため、内側第１異形セグメント導体３３ａが挿入されるスロット間隔よりも離れた位置に、各口出し用セグメント導体３２を組み付ける必要がある。この場合は、口出し用セグメント導体３２同士が離れてしまうため、各口出し用セグメント導体３２の口出し線部３２３をステータコア９上に這わせて近接させる必要があり、口出し線部３２３が長くなる欠点がある。このような欠点を解消するために、本実施形態では、次に説明する内側第２異形セグメント導体３４ａを新たに設けた。 As shown in FIG. 3, the inner first irregularly shaped segment conductor 33a has a head 332a located above the head 312 of the standard segment conductor 31; It has a straight line shape that straddles a plurality of portions 312. If only this inner first irregularly shaped segment conductor 33a is incorporated into the stator core 9, and if a plurality of inner first irregularly shaped segment conductors 33a are arranged nearby, their heads 332a will interfere with each other. For this reason, it is necessary to assemble each lead segment conductor 32 at a position farther apart than the slot interval into which the inner first irregularly shaped segment conductor 33a is inserted. In this case, since the lead-out segment conductors 32 are separated from each other, the lead-out wire portions 323 of each lead-out segment conductors 32 must be brought close to each other by running over the stator core 9, which has the disadvantage that the lead-out wire portions 323 become long. be. In order to eliminate such drawbacks, in this embodiment, an inner second irregularly shaped segment conductor 34a, which will be described next, is newly provided.

図８は、内側第２異形セグメント導体３４ａの外観図である。図８に示すように、内側第２異形セグメント導体３４ａは、所定の間隔にあるスロット内に配置される一対の直線部３４１と、固定子４０の軸方向におけるステータコア９の一方の片側にあり、頭部３４２ａを有する折り曲げ部３４３ａと、ステータコア９の他方の片側に形成される一対の端末部３４４とを有する。一対の端末部３４４の図示点線は、内側第２異形セグメント導体３４ａを端末部３４４の先端からスロット内へ挿入するために直線形状になっているが、スロットへ挿入後に曲げ成形されて標準セグメント導体３１の端末部３１４と接続される。 FIG. 8 is an external view of the inner second irregularly shaped segment conductor 34a. As shown in FIG. 8, the inner second irregularly shaped segment conductor 34a has a pair of straight portions 341 arranged in slots at predetermined intervals, and is located on one side of the stator core 9 in the axial direction of the stator 40, It has a bent portion 343a having a head portion 342a, and a pair of terminal portions 344 formed on the other side of the stator core 9. The illustrated dotted lines of the pair of terminal parts 344 are linear in order to insert the inner second irregularly shaped segment conductor 34a into the slot from the tip of the terminal part 344, but after being inserted into the slot, it is bent and formed into a standard segment conductor. It is connected to the terminal unit 314 of No. 31.

図７に示す内側第１異形セグメント導体３３ａの折り曲げ部３３３ａの起点から頭部３３２ａまでの高さｈ１は、図８に示す内側第２異形セグメント導体３４ａの折り曲げ部３４３ａの起点から頭部３４２ａまでの高さｈ２より大きい。 The height h1 from the starting point of the bent portion 333a of the inner first irregularly shaped segment conductor 33a to the head 332a shown in FIG. is greater than the height h2.

内側第１異形セグメント導体３３ａ、内側第２異形セグメント導体３４ａは、図３に示すように、標準セグメント導体３１、口出し用セグメント導体３２とともにステータコア９のスロットに嵌装されて、内側コイル２０ａを形成する。ここで、内側第２異形セグメント導体３４ａは、内側コイル２０ａを形成する標準セグメント導体３１の頭部位置に対して、固定子４０の内側に頭部位置がある。そして、内側第２異形セグメント導体３４ａの頭部は、標準セグメント導体３１の頭部よりも、固定子４０の軸方向における位置がステータコア９に近い。さらに、複数の内側第２異形セグメント導体３４ａの其々は、複数の標準セグメント導体３１の間に頭部位置がある。また、固定子４０に配置される内側第２異形セグメント導体３４ａの数は、標準セグメント導体３１の数より少ない。また、内側第２異形セグメント導体３４ａの頭部３４２ａは、内側第２異形セグメント導体３４ａの折り曲げ部３４３ａにおける他の部分よりも、ステータコア９から遠い位置にある。この場合、頭部３４２ａは、ステータコア９の片側端面に平行な直線状であってもよく、直線状に限らずその他の形状、例えば、Ｓ字状であってもよい。なお、頭部３４２ａは、内側第２異形セグメント導体３４ａの折り曲げ部３４３ａにおける他の部分よりも、固定子４０の軸方向においてステータコア９から遠い位置にあってもよい。 As shown in FIG. 3, the first inner irregularly shaped segment conductor 33a and the second inner irregularly shaped segment conductor 34a are fitted into the slots of the stator core 9 together with the standard segment conductor 31 and the lead segment conductor 32 to form the inner coil 20a. do. Here, the head position of the inner second irregular segment conductor 34a is located inside the stator 40 with respect to the head position of the standard segment conductor 31 forming the inner coil 20a. The head of the inner second irregular segment conductor 34a is located closer to the stator core 9 in the axial direction of the stator 40 than the head of the standard segment conductor 31. Further, each of the plurality of inner second irregularly shaped segment conductors 34 a has a head position between the plurality of standard segment conductors 31 . Further, the number of inner second irregularly shaped segment conductors 34a arranged on the stator 40 is smaller than the number of standard segment conductors 31. Further, the head 342a of the second inner irregularly shaped segment conductor 34a is located further from the stator core 9 than the other portion of the bent portion 343a of the second inner irregularly shaped segment conductor 34a. In this case, the head portion 342a may have a linear shape parallel to one end surface of the stator core 9, and may not be limited to a linear shape but may have another shape, for example, an S-shape. Note that the head 342a may be located further from the stator core 9 in the axial direction of the stator 40 than the other portions of the bent portion 343a of the inner second irregularly shaped segment conductor 34a.

このように、頭部３４２ａを固定子４０の内周側に配置した内側第２異形セグメント導体３４ａを設けたので、内側第１異形セグメント導体３３ａと内側第２異形セグメント導体３４ａとの干渉を回避して、異形セグメント導体３３、３４を近接して配置できる。これにより、異形セグメント導体３３、３４の配置自由度が高くなり、複数の口出し用セグメント導体３２を近場に配置する配線が可能になるため、口出し用セグメント導体３２の口出し線部３２３の長さを短くすることが可能である。さらに、内側第１異形セグメント導体３３ａに比べて内側第２異形セグメント導体３４ａは頭部３４３ａの位置をステータコア９に近い位置に配置することで、内側第２異形セグメント導体３４ａの長さを低減することも可能である。例えば、内側第１異形セグメント導体３３ａでは長さが１４５ｍｍであったものが、内側第２異形セグメント導体３４ａの長さは１３２ｍｍに低減可能である。 In this way, since the inner second irregularly shaped segment conductor 34a with the head 342a disposed on the inner peripheral side of the stator 40 is provided, interference between the inner first irregularly shaped segment conductor 33a and the inner second irregularly shaped segment conductor 34a is avoided. Thus, the deformed segment conductors 33 and 34 can be placed close to each other. As a result, the degree of freedom in arranging the irregularly shaped segment conductors 33 and 34 is increased, and wiring in which a plurality of lead-out segment conductors 32 can be arranged in close proximity becomes possible. It is possible to make it shorter. Further, by arranging the head 343a of the second inner irregularly shaped segment conductor 34a closer to the stator core 9 than the first inner irregularly shaped segment conductor 33a, the length of the second inner irregularly shaped segment conductor 34a is reduced. It is also possible. For example, the length of the inner first irregularly shaped segment conductor 33a was 145 mm, but the length of the inner second irregularly shaped segment conductor 34a can be reduced to 132 mm.

次に、外側コイル２０ｂを構成する外側第１異形セグメント導体３３ｂ、外側第２異形セグメント導体３４ｂについて説明する。図３に示すように、外側第１異形セグメント導体３３ｂはその頭部３３２ｂ（図９参照）が固定子４０の外周側を向くように形成されており、内側第１異形セグメント導体３３ａとはその頭部３３２ａ（図７参照）の向きが異なる。さらに、図３に示すように、外側第２異形セグメント導体３４ｂはその頭部３４２ｂ（図１０参照）が固定子４０の外周側を向くように形成されており、内側第２異形セグメント導体３４ａとはその頭部３４２ａ（図８参照）の向きが異なる。 Next, the first outer irregularly shaped segment conductor 33b and the second outer irregularly shaped segment conductor 34b that constitute the outer coil 20b will be explained. As shown in FIG. 3, the outer first irregularly shaped segment conductor 33b is formed such that its head 332b (see FIG. 9) faces the outer circumferential side of the stator 40, and the inner first irregularly shaped segment conductor 33a is different from the head 332b (see FIG. 9). The orientation of the head 332a (see FIG. 7) is different. Furthermore, as shown in FIG. 3, the outer second irregularly shaped segment conductor 34b is formed such that its head 342b (see FIG. 10) faces the outer peripheral side of the stator 40, and the outer second irregularly shaped segment conductor 34b is formed such that its head 342b (see FIG. 10) faces the outer peripheral side of the stator 40. The orientation of the head 342a (see FIG. 8) is different.

図９は、外側第１異形セグメント導体３３ｂの外観図である。図９に示すように、外側第１異形セグメント導体３３ｂは、所定の間隔にあるスロット内に配置される一対の直線部３３１と、固定子４０の軸方向におけるステータコア９の一方の片側にあり、頭部３３２ｂを有する折り曲げ部３３３ｂと、ステータコア９の他方の片側に形成される一対の端末部３３４とを有する。一対の端末部３３４の図示点線は、外側第１異形セグメント導体３３ｂを端末部３３４の先端からスロット内へ挿入するために直線形状になっているが、スロットへ挿入後に曲げ成形されて標準セグメント導体３１の端末部３１４と接続される。 FIG. 9 is an external view of the outer first irregularly shaped segment conductor 33b. As shown in FIG. 9, the outer first irregularly shaped segment conductor 33b has a pair of straight portions 331 arranged in slots at a predetermined interval, and is located on one side of the stator core 9 in the axial direction of the stator 40, It has a bent portion 333b having a head portion 332b, and a pair of terminal portions 334 formed on the other side of the stator core 9. The illustrated dotted lines of the pair of terminal parts 334 are straight lines in order to insert the outer first irregularly shaped segment conductor 33b into the slot from the tip of the terminal part 334, but after being inserted into the slot, it is bent and formed into a standard segment conductor. It is connected to the terminal unit 314 of No. 31.

外側第１異形セグメント導体３３ｂは、図３に示すように、外側第１異形セグメント導体３３ｂの頭部３３２ｂが標準セグメント導体３１の頭部３１２の上に存在しており、標準セグメント導体３１の頭部３１２を複数跨ぐ直線状となっている。仮に、この外側第１異形セグメント導体３３ｂのみをステータコア９に組み込んだ場合は、複数の外側第１異形セグメント導体３３ｂを近傍に配置すると、その頭部３３２ｂが互いに干渉してしまう。このため、外側第１異形セグメント導体３３ｂが挿入されるスロット間隔よりも離れた位置に、各口出し用セグメント導体３２を組み付ける必要がある。この場合は、口出し用セグメント導体３２同士が離れてしまうため、各口出し用セグメント導体３２の口出し線部３２３をステータコア９上に這わせて近接させる必要があり、口出し線部３２３が長くなる欠点がある。このような欠点を解消するために、本実施形態では、次に説明する外側第２異形セグメント導体３４ｂを新たに設けた。 As shown in FIG. 3, the outer first irregularly shaped segment conductor 33b is such that the head 332b of the outer first irregularly shaped segment conductor 33b is located on the head 312 of the standard segment conductor 31, and It has a straight line shape that straddles a plurality of portions 312. If only this outer first irregularly shaped segment conductor 33b is incorporated into the stator core 9, and if a plurality of outer first irregularly shaped segment conductors 33b are arranged nearby, their heads 332b will interfere with each other. Therefore, it is necessary to assemble each lead segment conductor 32 at a position farther apart than the slot interval into which the outer first irregularly shaped segment conductor 33b is inserted. In this case, since the lead-out segment conductors 32 are separated from each other, the lead-out wire portions 323 of each lead-out segment conductors 32 must be brought close to each other by running over the stator core 9, which has the disadvantage that the lead-out wire portions 323 become long. be. In order to eliminate such drawbacks, in this embodiment, an outer second irregularly shaped segment conductor 34b, which will be described next, is newly provided.

図１０は、外側第２異形セグメント導体３４ｂの外観図である。図１０に示すように、外側第２異形セグメント導体３４ｂは、所定の間隔にあるスロット内に配置される一対の直線部３４１と、固定子４０の軸方向におけるステータコア９の一方の片側にあり、頭部３４２ｂを有する折り曲げ部３４３ｂと、ステータコア９の他方の片側に形成される一対の端末部３４４とを有する。一対の端末部３４４の図示点線は、外側第２異形セグメント導体３４ｂを端末部３４４の先端からスロット内へ挿入するために直線形状になっているが、スロットへ挿入後に曲げ成形されて標準セグメント導体３１の端末部３１４と接続される。 FIG. 10 is an external view of the outer second irregularly shaped segment conductor 34b. As shown in FIG. 10, the outer second irregularly shaped segment conductor 34b has a pair of straight portions 341 arranged in slots at a predetermined interval, and is located on one side of the stator core 9 in the axial direction of the stator 40, It has a bent portion 343b having a head portion 342b, and a pair of terminal portions 344 formed on the other side of the stator core 9. The illustrated dotted lines of the pair of terminal parts 344 are linear in order to insert the outer second irregularly shaped segment conductor 34b into the slot from the tip of the terminal part 344, but after being inserted into the slot, it is bent and formed into a standard segment conductor. It is connected to the terminal unit 314 of No. 31.

図９に示す外側第１異形セグメント導体３３ｂの折り曲げ部３３３ｂの起点から頭部３３２ｂまでの高さｈ１は、図１０に示す外側第２異形セグメント導体３４ｂの折り曲げ部３４３ｂの起点から頭部３４２ｂまでの高さｈ２より大きい。 The height h1 from the starting point of the bent portion 333b of the outer first irregularly shaped segment conductor 33b to the head 332b shown in FIG. is greater than the height h2.

外側第１異形セグメント導体３３ｂ、外側第２異形セグメント導体３４ｂは、図３に示すように、標準セグメント導体３１、口出し用セグメント導体３２とともにステータコア９のスロットに嵌装されて、外側コイル２０ｂを形成する。ここで、外側第２異形セグメント導体３４ｂは、外側コイル２０ｂを形成する標準セグメント導体３１の頭部位置に対して、固定子４０の外周側に頭部位置がある。そして、図４に示すように、外側第２異形セグメント導体３４ｂの頭部は、標準セグメント導体３１の頭部よりも、固定子４０の軸方向における位置がステータコア９に近い。さらに、複数の外側第２異形セグメント導体３４ｂの其々は、複数の標準セグメント導体３１の間に頭部位置がある。また、固定子４０に配置される外側第２異形セグメント導体３４ｂの数は、標準セグメント導体３１の数より少ない。また、外側第２異形セグメント導体３４ｂの頭部３４２ｂは、外側第２異形セグメント導体３４ｂの折り曲げ部３４３ｂにおける他の部分よりも、ステータコア９から遠い位置にある。この場合、頭部３４２ｂは、ステータコア９の片側端面に平行な直線状であってもよく、直線状に限らずその他の形状、例えば、Ｓ字状であってもよい。なお、頭部３４２ｂは、外側第２異形セグメント導体３４ｂの折り曲げ部３４３ｂにおける他の部分よりも、固定子４０の軸方向においてステータコア９から遠い位置にあってもよい。 As shown in FIG. 3, the first outer odd-shaped segment conductor 33b and the second outer odd-shaped segment conductor 34b are fitted into the slots of the stator core 9 together with the standard segment conductor 31 and the lead-out segment conductor 32 to form the outer coil 20b. do. Here, the head position of the outer second irregularly shaped segment conductor 34b is on the outer peripheral side of the stator 40 with respect to the head position of the standard segment conductor 31 forming the outer coil 20b. As shown in FIG. 4, the head of the outer second irregular segment conductor 34b is located closer to the stator core 9 in the axial direction of the stator 40 than the head of the standard segment conductor 31. Further, each of the plurality of outer second irregularly shaped segment conductors 34b has a head position between the plurality of standard segment conductors 31. Further, the number of outer second irregular segment conductors 34b arranged on the stator 40 is smaller than the number of standard segment conductors 31. Further, the head 342b of the second outer irregularly shaped segment conductor 34b is located further from the stator core 9 than the other portion of the bent portion 343b of the second outer irregularly shaped segment conductor 34b. In this case, the head portion 342b may have a linear shape parallel to one end surface of the stator core 9, and may not be limited to a linear shape but may have another shape, for example, an S-shape. Note that the head 342b may be located further from the stator core 9 in the axial direction of the stator 40 than the other portions of the bent portion 343b of the second outer irregularly shaped segment conductor 34b.

このように、頭部３４２ｂを固定子４０の外周側に配置した外側第２異形セグメント導体３４ｂを設けたので、外側第１異形セグメント導体３３ｂと外側第２異形セグメント導体３４ｂとの干渉を回避して、異形セグメント導体３３、３４を近接して配置できる。これにより、異形セグメント導体３３、３４の配置自由度が高くなり、複数の口出し用セグメント導体３２を近場に配置する配線が可能になるため、口出し用セグメント導体３２の口出し線部３２３の長さを短くすることが可能である。さらに、外側第１異形セグメント導体３３ｂに比べて外側第２異形セグメント導体３４ｂは頭部３４３ａの位置をステータコア９に近い位置に配置することで、外側第２異形セグメント導体３４ｂの長さを低減することも可能である。例えば、外側第１異形セグメント導体３３ｂでは長さが１４５ｍｍであったものが、外側第２異形セグメント導体３４ｂの長さは１３２ｍｍに低減可能である。 In this way, since the outer second irregularly shaped segment conductor 34b with the head 342b disposed on the outer peripheral side of the stator 40 is provided, interference between the outer first irregularly shaped segment conductor 33b and the outer second irregularly shaped segment conductor 34b is avoided. Therefore, the irregularly shaped segment conductors 33 and 34 can be arranged close to each other. As a result, the degree of freedom in arranging the irregularly shaped segment conductors 33 and 34 is increased, and wiring in which a plurality of lead-out segment conductors 32 can be arranged in close proximity becomes possible. It is possible to make it shorter. Furthermore, by arranging the head 343a of the second outer odd-shaped segment conductor 34b closer to the stator core 9 than the first outer odd-shaped segment conductor 33b, the length of the second outer odd-shaped segment conductor 34b is reduced. It is also possible. For example, while the length of the outer first irregularly shaped segment conductor 33b was 145 mm, the length of the outer second irregularly shaped segment conductor 34b can be reduced to 132 mm.
