Description

コイル状部材及びコイル装置Coiled member and coil device
 本発明は、コアの周りに配設されるコイル状部材及びこのコイル状部材を備えたコイル装置に関する。 The present invention relates to a coiled member disposed around a core and a coil device provided with the coiled member.
 コアの周りにコイル状部材が配設されたコイル部を有するコイル装置としては、例えば、モータ、発電機、又は、トランス等の電気機器が挙げられ、広く使用されている。このようなコイル装置としては、例えば、環状部材の径方向に複数のコアを配設し、各コアの周りにそれぞれコイル状部材を配設したものが知られている。このコイル装置では、低損失科及び小型化を図るうえで、コイル状部材の占積率を高めることが求められている。 Examples of the coil device having a coil portion in which a coil-shaped member is disposed around a core include electric devices such as a motor, a generator, and a transformer, and are widely used. As such a coil device, for example, a device in which a plurality of cores are arranged in the radial direction of an annular member and a coil-like member is arranged around each core is known. In this coil device, it is required to increase the space factor of the coiled member in order to reduce the loss and size.
 しかし、環状部材の径方向に複数のコアを配設したコイル装置では、隣接する各コアの間の空間が、環状部材の中心側よりも外側の方が広くなるので、平角線を巻回したコイル状部材を配設すると、外側に隙間できてしまうという問題があった。そのため、平角線を用いた場合には、60%程度の占積率しか得ることができなかった。 However, in the coil device in which a plurality of cores are arranged in the radial direction of the annular member, the space between adjacent cores is wider outside the center side of the annular member, so a rectangular wire is wound. When the coil-shaped member is disposed, there is a problem that a gap is formed on the outside. Therefore, when a rectangular wire is used, only a space factor of about 60% can be obtained.
 そこで、丸線を積層して巻くことによりコイル状部材を形成し、コアの外側において丸線の積層数を多くすることにより、占積率を高める方法も提案されている(特許文献1参照)。しかしながら、丸線を積層した場合、隣接する丸線の間に隙間ができてしまうので、占積率を十分に高くすることができないという問題があった。また、積層するので、放熱性が低下してしまい、丸線で発生した熱により抵抗が上昇してしまうという問題もあった。更に、コアの外側において積層数を多くするなど製造方法が複雑でコストが高くなってしまうという問題もあった。 Then, the method of raising a space factor by forming a coil-shaped member by laminating | stacking and winding a round wire and increasing the number of lamination | stacking of a round wire in the outer side of a core is also proposed (refer patent document 1). . However, when round wires are stacked, a gap is formed between adjacent round wires, and there is a problem that the space factor cannot be sufficiently increased. Moreover, since it laminated | stacked, heat dissipation fell, and there also existed a problem that resistance raised with the heat | fever which generate | occur | produced with the round wire. Furthermore, there is a problem that the manufacturing method is complicated and the cost is increased, such as increasing the number of laminated layers outside the core.

 本発明は、このような問題に基づきなされたものであり、容易かつ安価に占積率を高くすることができるコイル状部材及びコイル装置を提供することを目的とする。 The present invention has been made based on such a problem, and an object of the present invention is to provide a coil-shaped member and a coil device that can increase the space factor easily and inexpensively.
 本発明のコイル状部材は、コアの周りに配設されるものであって、コアの周りを巻くように配設される導線を有し、導線は、コアの周方向に沿うように形成された複数の導線部材を接合することにより構成されたものである。 The coil-shaped member of the present invention is disposed around the core and has a conductive wire disposed so as to wind around the core, and the conductive wire is formed along the circumferential direction of the core. The plurality of conductor members are joined together.
 本発明のコイル装置は、コアの周りにコイル状部材が配設されたコイル部を有するものであって、コイル状部材は、コアの周りを巻くように配設された導線を有し、導線は、コアの周方向に沿うように形成された複数の導線部材を接合することにより構成されたものである。 The coil device of the present invention has a coil portion in which a coil-shaped member is disposed around a core, and the coil-shaped member has a conductive wire disposed so as to wind around the core, Is constituted by joining a plurality of conductor members formed along the circumferential direction of the core.
 本発明によれば、コアの周方向に沿うように形成された複数の導線部材を接合することにより、コアの周りを巻くように配設される導線を構成するようにしたので、コアの形状及びコイル状部材が配設される空間部の形状に合わせて、導線部材を形成し、接合することができる。よって、容易かつ安価に、コアの形状及びコイル状部材が配設される空間部の形状に合ったコイル状部材を形成することができ、コイル状部材の占積率を高くすることができる。 According to the present invention, since a plurality of conductor members formed so as to extend along the circumferential direction of the core are joined, the conductor arranged to be wound around the core is configured. And a conducting wire member can be formed and joined according to the shape of the space part by which a coil-shaped member is arranged. Therefore, it is possible to easily and inexpensively form a coil-shaped member that matches the shape of the core and the shape of the space where the coil-shaped member is disposed, and the space factor of the coil-shaped member can be increased.
 特に、コアの軸方向の一方から他方に向かい、導線の幅が広くなるように、各導線部材の幅を変化させて接合するようにすれば、コアが、環状部材に対して径方向に突出するように複数配置されている場合に、環状部材の径方向の外側に向かい、導線の幅を広くすることができる。よって、コイル状部材の占積率を高くすることができる。 In particular, the core protrudes in the radial direction with respect to the annular member if the width of each conductor member is changed so that the width of the conductor wire increases from one to the other in the axial direction of the core. When a plurality of the wires are arranged, the width of the conducting wire can be increased toward the outer side in the radial direction of the annular member. Therefore, the space factor of a coil-shaped member can be made high.
 また、コアの軸方向の一方から他方に向かい、導線の高さが低くなるように、各導線部材の高さ変化させて接合するようにすれば、コアが、環状部材に対して径方向に突出するように複数配置されている場合に、環状部材の径方向の外側に向かい、導線の高さを低くすることができる。よって、導線の断面積を一定とし、導線の抵抗を均一とすることができる。 Moreover, if the height of each conductor member is changed so that the height of the conductor wire decreases from one to the other in the axial direction of the core, the core is radially connected to the annular member. In the case where a plurality of protrusions are arranged so as to protrude, the height of the conducting wire can be lowered toward the outer side in the radial direction of the annular member. Therefore, the cross-sectional area of the conducting wire can be made constant and the resistance of the conducting wire can be made uniform.

 以下、本発明の実施の形態について図面を参照して詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
 図1は、本実施の形態に係るコイル状部材10を備えたコイル装置20の構成を表すものである。図2は、図1に示したコイル状部材10を取出して表すものであり、図3は、図2に示したコイル状部材10をI方向から見た状態を表している。このコイル装置20としては、例えば、モータ、発電機、又は、トランス等の電気機器が挙げられ、コイル状部材10は、例えば、ステータに用いられる。 FIG. 1 shows a configuration of a coil device 20 including a coiled member 10 according to the present embodiment. 2 shows the coiled member 10 shown in FIG. 1 taken out, and FIG. 3 shows the coiled member 10 shown in FIG. 2 viewed from the I direction. Examples of the coil device 20 include an electric device such as a motor, a generator, or a transformer. The coil-shaped member 10 is used for a stator, for example.
 コイル装置20は、例えば、複数のコア21が間隔を開けて設けられた環状部材22を備えている。コア21は、例えば、環状部材22に対して、環状部材22の径方向に突出するように配設されており、コア21の軸方向を環状部材22の径方向としている。コア21は、例えば、複数の電磁鋼板を積層して構成されている。各コア21の間には、コイル状部材10を配設するための空間部23が形成されている。各空間部23は、例えば、環状部材22の径方向の外側に向かい周方向の幅が広くなっている。なお、図1では、コア21を環状部材22の外周側に配設する場合を示したが、内周側に配設するようにしてもよい。 The coil device 20 includes, for example, an annular member 22 in which a plurality of cores 21 are provided at intervals. For example, the core 21 is disposed so as to protrude in the radial direction of the annular member 22 with respect to the annular member 22, and the axial direction of the core 21 is the radial direction of the annular member 22. For example, the core 21 is configured by laminating a plurality of electromagnetic steel plates. Between each core 21, the space part 23 for arrange | positioning the coil-shaped member 10 is formed. For example, each space 23 has a width in the circumferential direction that increases toward the outside in the radial direction of the annular member 22. 1 shows the case where the core 21 is disposed on the outer peripheral side of the annular member 22, the core 21 may be disposed on the inner peripheral side.
 各コア21の周りには、例えば、絶縁材料よりなるコイルボビン24を介して、コイル状部材10が配設されており、コア21とコイル状部材10とでコイル部25を構成している。コイル状部材10は、例えば、コア21の周りを巻くように配設された導線11を有している。導線11は、例えば、1周毎に、コア21の軸方向に位置をずらして連続して整列配置されている。導線11は、例えば、銅等の導電性材料により構成されている。導線11の長さ方向に対して垂直な断面形状は、矩形状であることが好ましい。コイル状部材10の占積率を高くすることができるからである。コア21の軸方向において隣接する導線11の間には、例えば、図示しないが、絶縁体である絶縁フィルムが挿入されている。 The coil-shaped member 10 is disposed around each core 21 via, for example, a coil bobbin 24 made of an insulating material, and the core 21 and the coil-shaped member 10 constitute a coil portion 25. The coil-shaped member 10 has the conducting wire 11 arrange | positioned so that the circumference | surroundings of the core 21 may be wound, for example. For example, the conducting wire 11 is continuously arranged in a line-shifted position in the axial direction of the core 21 every round. The conducting wire 11 is made of a conductive material such as copper, for example. The cross-sectional shape perpendicular to the length direction of the conducting wire 11 is preferably rectangular. This is because the space factor of the coiled member 10 can be increased. Although not shown, for example, an insulating film that is an insulator is inserted between the conductors 11 adjacent in the axial direction of the core 21.
 また、導線11は、コア21の周方向に沿うように形成された複数の導線部材12を接合することにより構成されている。図4は、1つの導線部材12の構成例を表すものである。導線部材12の長さは、例えば、1周以下とすることが好ましい。なお、図4は、導線部材12の長さが1周の場合を示している。このように構成すれば、コア21の形状及び空間部23の形状に合わせて、導線部材12を容易に形成することができるので、容易かつ安価に、コイル状部材10の占積率を80%以上に高くすることができるからである。 Moreover, the conducting wire 11 is configured by joining a plurality of conducting wire members 12 formed along the circumferential direction of the core 21. FIG. 4 illustrates a configuration example of one conductor member 12. The length of the conductor member 12 is preferably, for example, one turn or less. FIG. 4 shows a case where the length of the conducting wire member 12 is one round. If comprised in this way, since the conductor member 12 can be easily formed according to the shape of the core 21 and the shape of the space part 23, the space factor of the coil-shaped member 10 is 80% easily and inexpensively. This is because it can be made higher.
 図5は、従来のコイル110の形状を表すものであり、1本の導線111を巻回して形成されている。図5に示したように、導線111を巻回して形成する場合には、導線111を湾曲させるので、角に丸みが生じてしまい直角とすることは難しい。これに対して、本実施の形態に係るコイル状部材10であれば、複数の導線部材12をコア21の形状及び空間部23の形状に合わせて形成したのち、各導線部材12を接合するので、角を直角とすることもでき、容易に占積率を高くすることができる。 FIG. 5 shows the shape of the conventional coil 110 and is formed by winding a single conducting wire 111. As shown in FIG. 5, when the conductive wire 111 is wound and formed, the conductive wire 111 is bent, so that the corners are rounded and it is difficult to form a right angle. On the other hand, in the case of the coil-shaped member 10 according to the present embodiment, since the plurality of conductor members 12 are formed in accordance with the shape of the core 21 and the shape of the space portion 23, the conductor members 12 are joined. The corners can also be right angles, and the space factor can be easily increased.
 また、従来のコイル110では、導線111を湾曲させるので、角の内周側が膨らんでしまい、隣接する導線111の間に隙間が生じてしまうのに対して、本実施の形態に係るコイル状部材10であれば、各導線部材12を目的の形状に加工してから接合するので、内周側が大きく膨らむことがなく、隣接する導線11の間の隙間を小さくすることができ、占積率を高くすることができる。 Moreover, in the conventional coil 110, since the conducting wire 111 is curved, the inner peripheral side of the corner swells and a gap is formed between the adjacent conducting wires 111, whereas the coiled member according to the present embodiment If it is 10, each conductor member 12 is processed into a desired shape and then joined, so that the inner peripheral side does not swell greatly, the gap between adjacent conductors 11 can be reduced, and the space factor can be reduced. Can be high.
 本実施の形態のコイル状部材10では、導線11は、例えば、コア21の軸方向の一方から他方に向かい、環状部材22の周方向における導線11の幅W1が広くなるように、各導線部材12の幅W1を変化させて接合することにより構成されることが好ましい。空間部23の幅は環状部材22の径方向の外側に向かい広くなっているので、それに合わせて導線11の幅W1を環状部材22の径方向の外側に向かい広くすることにより、コイル状部材10の占積率を高くすることができるからである。なお、環状部材22の周方向における導線11の幅W1というのは、環状部材22の周方向において、コア21の軸方向に対して垂直方向の導線11の長さである。 In the coil-shaped member 10 of the present embodiment, the conducting wire 11 is, for example, each conducting wire member so that the width W1 of the conducting wire 11 in the circumferential direction of the annular member 22 increases from one to the other in the axial direction of the core 21. It is preferable that the width W1 of 12 is changed and joined. Since the width of the space portion 23 increases toward the outer side in the radial direction of the annular member 22, the coil-shaped member 10 is formed by increasing the width W <b> 1 of the conductive wire 11 toward the outer side in the radial direction of the annular member 22 accordingly. This is because the space factor can be increased. The width W1 of the conducting wire 11 in the circumferential direction of the annular member 22 is the length of the conducting wire 11 in the direction perpendicular to the axial direction of the core 21 in the circumferential direction of the annular member 22.
 導線11は、また、例えば、コア21の軸方向の一方から他方に向かい、導線11の高さHが低くなるように、各導線部材12の高さHを変化させて接合することにより構成されることが好ましい。すなわち、環状部材22の径方向の外側に向かい、導線11の幅W1を広くするのに合わせて、導線11の高さHを低くすることが好ましい。導線11の長さ方向に対して垂直な方向の断面積を一定とすることにより、導線11の抵抗を一定とすることができるからである。導線11の高さHというのは、コア21の軸方向における長さである。 The conducting wire 11 is also configured, for example, by joining each of the conducting wire members 12 with the height H changed so that the height H of the conducting wire 11 decreases from one to the other in the axial direction of the core 21. It is preferable. That is, it is preferable to reduce the height H of the conducting wire 11 in accordance with the increase in the width W1 of the conducting wire 11 toward the outside in the radial direction of the annular member 22. This is because the resistance of the conducting wire 11 can be made constant by making the cross-sectional area perpendicular to the length direction of the conducting wire 11 constant. The height H of the conducting wire 11 is the length of the core 21 in the axial direction.
 なお、導線11の断面積は、環状部材22の周方向と、周方向に対して垂直な方向とで、一定としてもよいが、目的に応じて異ならせてもよい。例えば、環状部材22の周方向における導線11の幅W1と、環状部材22の周方向に対して垂直な方向における導線11の幅W2とは、同一でもよいが、異なっていてもよく、コア21の軸方向の一方から他方に向かい、導線11の幅W1のみを広くし、幅W2を一定とするようにしてもよい。すなわち、コア21の軸方向の一方から他方に向かい、導線11の幅が、コア21の周方向の少なくとも一部、幅W1において、広くなるようにしてもよい。環状部材22の周方向に対して垂直な方向におけるコイル状部材10の幅を大きくせずに、空間部23におけるコイル状部材10の占有率を高くすることができるからである。本実施の形態のコイル状部材10によれば、複数の導線部材12を接合して導線11を構成するので、任意に設計することが可能である。 In addition, although the cross-sectional area of the conducting wire 11 may be constant in the circumferential direction of the annular member 22 and the direction perpendicular to the circumferential direction, it may be varied depending on the purpose. For example, the width W1 of the conducting wire 11 in the circumferential direction of the annular member 22 may be the same as or different from the width W2 of the conducting wire 11 in the direction perpendicular to the circumferential direction of the annular member 22. From one side to the other in the axial direction, only the width W1 of the conductive wire 11 may be widened and the width W2 may be constant. That is, the width of the conducting wire 11 may be widened in at least a part of the circumferential direction of the core 21, the width W <b> 1, from one side of the core 21 to the other side. This is because the occupation ratio of the coil-shaped member 10 in the space 23 can be increased without increasing the width of the coil-shaped member 10 in the direction perpendicular to the circumferential direction of the annular member 22. According to the coil-shaped member 10 of the present embodiment, the plurality of conductor members 12 are joined to form the conductor 11, so that it can be arbitrarily designed.
 このコイル状部材10は、例えば、銅板又は銅線等の導電性部材を加工することにより、コア21の形状及び空間部23の形状に合わせて各導線部材12を形成したのち、同線部材の長さ方向において隣接する導線部材12の隣接する端部同士を接合することにより形成することができる。接合は、電気溶接、高周波溶接、ろう付け、圧接等の各種方法を用いることができる。 For example, the coil-shaped member 10 is formed by processing a conductive member such as a copper plate or a copper wire to form each conductor member 12 in accordance with the shape of the core 21 and the shape of the space 23, and then It can form by joining the adjacent edge parts of the conducting wire member 12 adjacent in a length direction. Various methods such as electric welding, high-frequency welding, brazing, and pressure welding can be used for joining.
 このように本実施の形態によれば、コア21の周方向に沿うように形成された複数の導線部材12を接合することにより、コア21の周りを巻くように配設される導線11を構成するようにしたので、コア21の形状及び空間部23の形状に合わせて、導線部材12を形成し、接合することができる。よって、容易かつ安価に、コア21の形状及び空間部23の形状に合ったコイル状部材10を形成することができ、コイル状部材10の占積率を高くすることができる。 As described above, according to the present embodiment, the plurality of conductor members 12 formed so as to extend along the circumferential direction of the core 21 are joined to form the conductor 11 arranged so as to wind around the core 21. Since it was made to do, according to the shape of the core 21 and the shape of the space part 23, the conducting wire member 12 can be formed and joined. Therefore, the coil-shaped member 10 suitable for the shape of the core 21 and the shape of the space 23 can be formed easily and inexpensively, and the space factor of the coil-shaped member 10 can be increased.
 特に、コア21の軸方向の一方から他方に向かい、導線11の幅W1が広くなるように、各導線部材12の幅を変化させて接合するようにすれば、コア21が、環状部材22に対して径方向に突出するように複数配置されている場合に、環状部材22の径方向の外側に向かい、導線11の幅W1を広くすることができる。よって、コイル状部材10の占積率を高くすることができる。 In particular, the core 21 is attached to the annular member 22 by changing the width of each conductor member 12 so that the width W1 of the conductor 11 is increased from one to the other in the axial direction of the core 21. On the other hand, when it arrange | positions so that it may protrude in radial direction, the width W 1 of the conducting wire 11 can be made wide toward the outer side of the radial direction of the annular member 22. Therefore, the space factor of the coiled member 10 can be increased.
 また、コア21の軸方向の一方から他方に向かい、導線11の高さHが低くなるように、各導線部材12の高さを変化させて接合するようにすれば、コア21が、環状部材22に対して径方向に突出するように複数配置されている場合に、環状部材22の径方向の外側に向かい、導線11の高さHを低くすることができる。よって、導線11の断面積を一定とし、抵抗を均一とすることができる。 Moreover, if the height of each conducting wire member 12 is changed and joined so that the height H of the conducting wire 11 decreases from one to the other in the axial direction of the core 21, the core 21 becomes an annular member. When a plurality of the wires 22 are arranged so as to protrude in the radial direction with respect to the wire 22, the height H of the conductive wire 11 can be lowered toward the outside in the radial direction of the annular member 22. Therefore, the cross-sectional area of the conducting wire 11 can be made constant and the resistance can be made uniform.
 以上、実施の形態を挙げて本発明を説明したが、本発明は上記実施の形態に限定されるものではなく、種々変形可能である。例えば、図6に示したように、コア21の軸方向の一方から他方に向かい、導線11の高さHを一定とし、環状部材22の周方向における導線11の幅W1を広くするようにしてもよい。この場合も、環状部材22の周方向に対して垂直な方向における導線11の幅W2は、コア21の軸方向の一方から他方に向かい、幅W1と同様に広くするようにしてもよく、また、一定としてもよい。 The present invention has been described above with reference to the embodiment. However, the present invention is not limited to the above embodiment, and various modifications can be made. For example, as shown in FIG. 6, the height H of the conducting wire 11 is made constant from one to the other in the axial direction of the core 21, and the width W <b> 1 of the conducting wire 11 in the circumferential direction of the annular member 22 is increased. Also good. Also in this case, the width W2 of the conducting wire 11 in the direction perpendicular to the circumferential direction of the annular member 22 may be increased from one side to the other in the axial direction of the core 21 in the same manner as the width W1. It may be constant.
 また、例えば、導線11の少なくとも一部を絶縁体により被覆するようにしてもよい。例えば、各導線部材12を接合して導線11を形成したのち、導線11の少なくとも一部を絶縁体により被覆することにより構成することができる。 Further, for example, at least a part of the conductive wire 11 may be covered with an insulator. For example, after forming the conducting wire 11 by joining the conducting wire members 12, at least a part of the conducting wire 11 can be covered with an insulator.
 モータ、発電機、又は、トランス等の電気機器に用いることができる。 It can be used for electric devices such as motors, generators or transformers.
