Description
本発明は、温度センサの固定構造に関する。 The present invention relates to a temperature sensor fixing structure.
従来、この種の温度センサの固定構造としては、ステータコアのティースに巻回された複数の環状コイルの温度を測定する温度センサを固定するものが提案されている（例えば、特許文献１参照）。特許文献１では、環状コイル間を電気的に接続する接続部材を備え、その接続部材の一部に部材同士が対向するように折り曲げた曲げ部が形成されている。そして、曲げ部の間に温度センサを配置して金型に挿入し、曲げ部と温度センサとを接触させた状態で金型内に樹脂を注入する射出成形を行って固定部材を形成する。この固定部材が、曲げ部と温度センサとを接触させた状態で固定することにより、温度センサが精度よく温度を測定することができるとしている。 Conventionally, as a fixing structure for this type of temperature sensor, a structure for fixing a temperature sensor for measuring temperatures of a plurality of annular coils wound around teeth of a stator core has been proposed (for example, see Patent Document 1). In Patent Document 1, a connecting member that electrically connects the annular coils is provided, and a bent portion that is bent so that the members face each other is formed on a part of the connecting member. And a temperature sensor is arrange | positioned between bending parts, it inserts in a metal mold | die, injection molding which inject | pours resin in a metal mold | die in the state which made the bending part and temperature sensor contact is performed, and a fixing member is formed. The fixing member fixes the bent part and the temperature sensor in contact with each other, so that the temperature sensor can accurately measure the temperature.
しかしながら、上述した固定構造のように、射出成形により形成された固定部材を用いると、故障などで温度センサを交換する際に、温度センサを取り外したり取り付けたりするのに手間が掛かるものとなる。一方で、温度センサを容易に着脱可能とするために、取付寸法に余裕をもって温度センサを固定部材に取り付ける構成とすると、温度センサと測定対象との間に隙間が生じて温度測定精度が低下することがある。 However, when a fixing member formed by injection molding is used as in the fixing structure described above, it takes time to remove and attach the temperature sensor when replacing the temperature sensor due to a failure or the like. On the other hand, if the temperature sensor is attached to the fixing member with a sufficient mounting dimension in order to make the temperature sensor detachable easily, a gap is generated between the temperature sensor and the measurement target, and the temperature measurement accuracy is lowered. Sometimes.
本発明の温度センサの固定構造は、コイルの温度を精度よく測定可能としつつ温度センサを容易に交換可能とすることを主目的とする。 The main structure of the temperature sensor fixing structure of the present invention is to enable easy replacement of the temperature sensor while enabling accurate measurement of the coil temperature.
本発明の温度センサの固定構造は、上述の主目的を達成するために以下の手段を採った。 The temperature sensor fixing structure of the present invention adopts the following means in order to achieve the above-mentioned main object.
本発明の温度センサの固定構造は、
ステータコアに巻回された複数の環状コイルの温度を測定する温度センサの固定構造であって、
前記複数の環状コイルを含む導線に、該導線が軸回りに捩られ且つ環状に巻かれた状態の巻き捩り部を備え、
前記巻き捩り部内に前記温度センサが挿入された状態で固定されている
ことを特徴とする。
The fixing structure of the temperature sensor of the present invention is
A temperature sensor fixing structure for measuring temperatures of a plurality of annular coils wound around a stator core,
The conducting wire including the plurality of annular coils includes a winding twisted portion in a state where the conducting wire is twisted around an axis and wound annularly.
The temperature sensor is fixed in a state where the temperature sensor is inserted into the coiled torsion part.
この本発明の温度センサの固定構造では、複数の環状コイルを含む導線に、導線が軸回りに捩られ且つ環状に巻かれた巻き捩り部を備え、その巻き捩り部内に温度センサが挿入された状態で固定されている。これにより、温度センサは巻き捩り部を形成する導線の捩りの反力を受けるため、導線に接触した状態で温度センサを確実に固定することができる。また、温度センサが環状コイルの温度を精度よく測定することができる。さらに、温度センサは、巻き捩り部以外に拘束されないから、交換時には容易に取り外すことができる。また、温度センサの取り付けは、温度センサを巻き捩り部内に挿入するだけでよい。この結果、コイルの温度を精度よく測定可能としつつ温度センサを容易に交換可能とすることができる。 In the temperature sensor fixing structure according to the present invention, a conducting wire including a plurality of annular coils is provided with a winding torsion portion in which the conducting wire is twisted around an axis and wound in an annular shape, and the temperature sensor is inserted into the winding torsion portion. It is fixed in the state. Thereby, since the temperature sensor receives the reaction force of the torsion of the conducting wire that forms the twisted torsion part, the temperature sensor can be reliably fixed in a state where it is in contact with the conducting wire. Further, the temperature sensor can accurately measure the temperature of the annular coil. Furthermore, since the temperature sensor is not restrained except for the winding / twisting portion, it can be easily removed at the time of replacement. In addition, the temperature sensor can be attached only by inserting the temperature sensor into the winding twisted portion. As a result, the temperature sensor can be easily replaced while the coil temperature can be accurately measured.
ここで、複数の環状コイルを含む導線は、環状コイルを形成している導線と環状コイルを形成している導線に電気的に接続される導線（環状コイルの導線とは別部材の導線）とを含むものとしてもよい。また、巻き捩り部は、温度センサの断面寸法に合わせて環状に巻かれるものとしてもよい。 Here, the conducting wire including a plurality of annular coils includes a conducting wire forming the annular coil and a conducting wire electrically connected to the conducting wire forming the annular coil (a conducting wire different from the conducting wire of the annular coil). May be included. Further, the winding and twisting portion may be wound in an annular shape in accordance with the cross-sectional dimension of the temperature sensor.
次に、本発明を実施するための形態を実施例を用いて説明する。 Next, the form for implementing this invention is demonstrated using an Example.
図１は電動機のステータ１０の外観を示す外観斜視図であり、図２は温度センサ２０の固定構造の一例を示す説明図である。電動機のステータ１０は、打ち抜き加工などにより形成された電磁鋼板を複数積層して構成されたステータコア１２と、ステータ１０の径方向内側に突出した複数のティース１４と、複数のティース１４にそれぞれ環状に巻回された環状コイルを形成する各相（Ｕ相，Ｖ相，Ｗ相）の導線（コイル線）１６と、環状コイルの温度を測定するための温度センサ２０とを備える。なお、実施例では、ステータコア１２（各ティース１４）に集中巻きにより導線１６が巻回されて環状コイルを形成している。 FIG. 1 is an external perspective view showing an external appearance of a stator 10 of an electric motor, and FIG. 2 is an explanatory view showing an example of a fixing structure of a temperature sensor 20. A stator 10 of an electric motor has a stator core 12 formed by laminating a plurality of electromagnetic steel plates formed by stamping or the like, a plurality of teeth 14 projecting radially inward of the stator 10, and a plurality of teeth 14 in an annular shape. A conductive wire (coil wire) 16 of each phase (U phase, V phase, W phase) forming a wound annular coil and a temperature sensor 20 for measuring the temperature of the annular coil are provided. In the embodiment, the lead wire 16 is wound around the stator core 12 (each tooth 14) by concentrated winding to form an annular coil.
導線１６は、例えば、矩形断面の平角導体が用いられる。この平角導体は、銅などの導電性の高い金属性の平角線に、エナメル被覆などの絶縁被覆を施して構成されている。また、いずれか一相の導線１６において、隣り合う環状コイル（ティース１４）間を電気的に繋ぐ箇所に、導線１６を軸回りに捩りながら複数周に亘って環状に巻いた巻き捩り部１８が形成されている。隣り合う環状コイル間を繋ぐ箇所は、環状コイルから引き出される導線１６の渡り線であってもよいし、環状コイルを形成する導線１６の端部に接続されるバスバーなどの別の導線であってもよい。 For example, a rectangular conductor having a rectangular cross section is used as the conducting wire 16. This rectangular conductor is formed by applying an insulating coating such as enamel coating to a highly conductive metallic rectangular wire such as copper. Further, in any one phase of the conducting wire 16, a winding twisted portion 18 that is annularly wound over a plurality of circumferences while twisting the conducting wire 16 around the axis is provided at a place where the adjacent annular coils (teeth 14) are electrically connected. Is formed. The portion connecting the adjacent annular coils may be a connecting wire of the conducting wire 16 drawn out from the annular coil, or another conducting wire such as a bus bar connected to the end of the conducting wire 16 forming the annular coil. Also good.
温度センサ２０は、サーミスタなどの図示しない温度検出素子を備え、温度検出素子が樹脂部材によりモールドされて保護されている。この温度センサ２０は、環状の巻き捩り部１８内に挿入された状態で固定されている。このため、実施例の温度センサ２０は、巻き捩り部１８を測温部として、環状コイルの温度を測定することになる。 The temperature sensor 20 includes a temperature detection element (not shown) such as a thermistor, and the temperature detection element is molded and protected by a resin member. The temperature sensor 20 is fixed in a state of being inserted into the annular winding / twisting portion 18. For this reason, the temperature sensor 20 according to the embodiment measures the temperature of the annular coil using the winding / twisted portion 18 as a temperature measuring portion.
ここで、温度センサ２０を固定する際の様子を図３に示す。なお、図３では、各相の複数の環状コイルのうち、同相の導線１６が巻回された隣り合う２つの環状コイルを示す。上述したように、同相の環状コイル間を繋ぐ箇所において巻き捩り部１８が形成されている。この巻き捩り部１８は、温度センサ２０（樹脂モールド部分）の断面寸法と略同じ寸法に形成された図示しない棒状の治具に、導線１６を捩りながら複数周に亘って巻き付けることにより形成される。導線１６の捩りは、例えば、導線１６が弾性変形可能な範囲内で、導線１６の矩形断面の回転角度が導線１６の長手方向において徐々に変化していくよう、導線１６の軸回り（断面中心回り）に螺旋状に捩ることにより行なう。即ち、巻き捩り部１８は、導線１６が捩られ且つ環状に巻かれた状態となっている。図３（ａ）には、巻き捩り部１８を形成した後に、巻き捩り部１８から治具を抜き取った状態を示しており、模式的に３周分の捩り巻き部１８ａ，１８ｂ，１８ｃを示す。治具が抜き取られた巻き捩り部１８（各捩り巻き部１８ａ，１８ｂ，１８ｃ）は、導線１６の捩り（弾性変形）の反力により、元の状態（捩られていない状態）に戻ろうとするため、ばらけた状態となっている。 Here, FIG. 3 shows a state when the temperature sensor 20 is fixed. In addition, in FIG. 3, two adjacent annular coils around which the conducting wire 16 of the same phase is wound are shown among the plurality of annular coils of each phase. As described above, the winding / twisting portion 18 is formed at a place connecting the annular coils of the same phase. The winding / twisting portion 18 is formed by winding the lead wire 16 over a plurality of circumferences while twisting the wire 16 on a rod-shaped jig (not shown) formed to have substantially the same cross-sectional dimension as the temperature sensor 20 (resin mold portion). . The twisting of the conducting wire 16 is, for example, around the axis of the conducting wire 16 (in the center of the section) so that the rotation angle of the rectangular cross section of the conducting wire 16 gradually changes in the longitudinal direction of the conducting wire 16 within a range in which the conducting wire 16 can be elastically deformed. Around) and twist it in a spiral. That is, the winding / twisting portion 18 is in a state in which the conductive wire 16 is twisted and wound in an annular shape. FIG. 3A shows a state in which the jig is extracted from the wound torsion part 18 after the winding torsion part 18 is formed, and schematically shows the torsion winding parts 18a, 18b, and 18c for three rounds. . The twisted and twisted portion 18 (each twisted and wound portion 18a, 18b, 18c) from which the jig has been removed tends to return to the original state (not twisted) due to the reaction force of the twist (elastic deformation) of the conductor 16. Therefore, it is in a separated state.
このようにして形成した環状の巻き捩り部１８（１８ａ，１８ｂ，１８ｃ）内に温度センサ２０が通るよう、紙面に垂直な方向に温度センサ２０を挿入する。巻き捩り部１８は、温度センサ２０の断面寸法と略同じ寸法に形成された治具に巻き付けて形成されるため、巻き捩り部１８は温度センサ２０がちょうど嵌まるサイズとなっている。このため、温度センサ２０が挿入されると、図３（ｂ）に示すように、温度センサ２０に沿うように各捩り巻き部１８ａ〜１８ｃが整列した状態になる。このため、捩り巻き部１８の導線１６の捩り（弾性変形）の反力が温度センサ２０に作用して（例えば、図中矢印参照）、各捩り巻き部１８ａ，１８ｂ，１８ｃが温度センサ２０の表面に接触（密着）する状態となる。この捩り巻き部１８の捩りの反力により、温度センサ２０が巻き捩り部１８から脱落しないよう確実に固定される。上述したように、温度センサ２０のサーミスタ（温度検出素子）は樹脂モールドにより保護されているから、巻き捩り部１８の捩りの反力を受けても、サーミスタが破損するのを防止することができる。また、温度センサ２０は、測温部である巻き捩り部１８内に導線１６に接触した状態で覆われるため、環状コイル（導線１６）の温度を精度よく測定することが可能となる。 The temperature sensor 20 is inserted in a direction perpendicular to the paper surface so that the temperature sensor 20 passes through the annular winding / twisting portion 18 (18a, 18b, 18c) formed in this way. Since the winding / twisting portion 18 is formed by being wound around a jig formed to have substantially the same cross-sectional dimension as the temperature sensor 20, the winding / twisting portion 18 has a size that allows the temperature sensor 20 to be fitted. For this reason, when the temperature sensor 20 is inserted, as shown in FIG. 3B, the torsion winding portions 18 a to 18 c are aligned along the temperature sensor 20. For this reason, the reaction force of torsion (elastic deformation) of the conducting wire 16 of the torsion winding portion 18 acts on the temperature sensor 20 (see, for example, the arrow in the figure), and each torsion winding portion 18a, 18b, 18c It will be in the state of contacting (adhering) to the surface. The temperature sensor 20 is securely fixed so as not to drop off from the twisted and twisted portion 18 by the reaction force of the twisted and twisted portion 18. As described above, since the thermistor (temperature detection element) of the temperature sensor 20 is protected by the resin mold, it is possible to prevent the thermistor from being damaged even if it receives the reaction force of the torsional portion 18. . In addition, since the temperature sensor 20 is covered in the state where the temperature sensor 20 is in contact with the conductive wire 16 in the twisted and twisted portion 18 that is a temperature measuring unit, the temperature of the annular coil (conductive wire 16) can be accurately measured.
ここで、巻き捩り部１８の捩りの巻き数は図３に例示した３巻き（３周）に限られるものではなく、導線１６の断面寸法や温度センサ２０の紙面垂直方向（挿入方向）の長さなどに応じて、適宜設定すればよい。実施例の巻き捩り部１８は温度センサ２０の測温部となるため、測温精度をより高めるために、巻き捩り部１８は、温度センサ２０の温度検出素子の配置部分を覆う程度の巻き数がある方がよい。また、巻き捩り部１８の巻き数が少ないと、温度センサ２０の固定に必要な応力が温度センサ２０の樹脂モールドに集中して作用して樹脂モールドの破損に繋がるおそれがある。そのような応力集中を防止するためにも、巻き捩り部１８は、複数の巻き数（複数周）があることが望ましい。 Here, the number of winding turns of the winding torsion part 18 is not limited to the three windings (three rounds) illustrated in FIG. 3, but the cross-sectional dimension of the conductor 16 and the length of the temperature sensor 20 in the direction perpendicular to the paper surface (insertion direction) It may be set appropriately according to the situation. Since the winding torsion part 18 of the embodiment serves as a temperature measuring part of the temperature sensor 20, the winding torsion part 18 has a number of turns to cover the arrangement portion of the temperature detection element of the temperature sensor 20 in order to further improve the temperature measurement accuracy. There is better. In addition, when the number of turns of the winding / twisting portion 18 is small, stress necessary for fixing the temperature sensor 20 may concentrate on the resin mold of the temperature sensor 20 and may be damaged. In order to prevent such stress concentration, it is desirable that the winding twist portion 18 has a plurality of winding numbers (a plurality of turns).
以上説明した実施例の温度センサ２０の固定方法では、複数の環状コイルを形成する導線１６を軸回りに捩りながら環状に巻いた状態の巻き捩り部１８を備え、巻き捩り部１８内に温度センサ２０が挿入された状態で固定されている（巻き捩り部１８内に温度センサ２０を挿入することにより固定している）。これにより、温度センサ２０は巻き捩り部１８を形成する導線１６の捩りの反力を受けるため、導線１６に接触した状態で温度センサ２０を確実に固定することができると共に、温度センサ２０が環状コイルの温度を精度よく測定することができる。さらに、温度センサ２０は、導線１６の捩りの反力で固定されており、それ以外には拘束されないから、温度センサ２０の交換時には温度センサ２０を容易に取り外すことができる。また、温度センサ２０の取り付けは、温度センサ２０を巻き捩り部１８内に挿入するだけでよい。したがって、環状コイルの温度を精度よく測定可能としつつ温度センサ２０を容易に交換可能とすることができる。 In the fixing method of the temperature sensor 20 of the embodiment described above, the winding torsion part 18 is provided in a state where the conducting wire 16 forming a plurality of annular coils is wound around the axis while being annularly wound, and the temperature sensor is provided in the winding torsion part 18. 20 is fixed in a state where it is inserted (fixed by inserting the temperature sensor 20 into the winding twist portion 18). Thereby, since the temperature sensor 20 receives the reaction force of the twisting of the conducting wire 16 that forms the winding and twisting portion 18, the temperature sensor 20 can be securely fixed while being in contact with the conducting wire 16, and the temperature sensor 20 is annular. The coil temperature can be accurately measured. Furthermore, since the temperature sensor 20 is fixed by the reaction force of the torsion of the conducting wire 16 and is not restrained otherwise, the temperature sensor 20 can be easily removed when the temperature sensor 20 is replaced. Further, the temperature sensor 20 may be attached only by inserting the temperature sensor 20 into the winding / twisting portion 18. Therefore, the temperature sensor 20 can be easily replaced while the temperature of the annular coil can be accurately measured.
上述した実施例では、集中巻きにより形成された環状コイル間を繋ぐ箇所に巻き捩り部１８を備えるものとしたが、これに限られず、環状コイルを含む導線（環状コイルの温度を測定可能な導線）に巻き捩り部を備えるものであればよい。例えば、ステータコア１２に導線１６が分布巻きされたものにおいて、分布巻きの環状コイルを形成する導線（渡り部など）に巻き捩り部を備えるものとしてもよい。また、巻き捩り部は、環状コイルを形成する導線に形成されるものに限られず、環状コイルの導線に溶接などにより電気的に接続される導線に形成されるものでもよい。例えば、上述したように環状コイルの端部に接続されるバスバーなどの別の導線に巻き捩り部を形成してもよいし、環状コイルの各相の中性点に接続される中性線などの別の導線に巻き捩り部を形成してもよい。 In the above-described embodiment, the winding torsion portion 18 is provided at a location connecting the annular coils formed by concentrated winding. However, the present invention is not limited to this, and a conductor including the annular coil (a conductor capable of measuring the temperature of the annular coil). ) With a twisted torsional portion. For example, in the case where the conductive wire 16 is distributedly wound around the stator core 12, the conductive wire (crossover portion or the like) forming a distributed winding annular coil may be provided with a winding twist portion. Further, the wound and twisted portion is not limited to that formed on the conducting wire forming the annular coil, and may be formed on a conducting wire electrically connected to the conducting wire of the annular coil by welding or the like. For example, as described above, a torsion portion may be formed on another conductor such as a bus bar connected to the end of the annular coil, or a neutral wire connected to the neutral point of each phase of the annular coil. A winding twist portion may be formed on the other conductor.
上述した実施例では、温度センサ２０（樹脂モールド部分）の断面寸法と略同じ寸法に形成された図示しない棒状の治具に導線１６を捩りながら巻き付けることにより、巻き捩り部１８を形成するものとしたが、これに限られるものではない。例えば、温度センサ２０（樹脂モールド部分）の断面の四隅に相当する位置にピンなどを配置しておき、それらのピンに導線を捩りながら巻き付けることにより、巻き捩り部を形成するものなどとしてもよい。また、治具を用いるものに限られず、温度センサ２０に導線１６を捩りながら巻き付けることにより、巻き捩り部１８を形成してもよい。 In the above-described embodiment, the twisted and twisted portion 18 is formed by winding the lead wire 16 while twisting it around a rod-shaped jig (not shown) formed to have substantially the same cross-sectional dimension as the temperature sensor 20 (resin mold portion). However, it is not limited to this. For example, a pin or the like may be arranged at positions corresponding to the four corners of the cross section of the temperature sensor 20 (resin mold part), and a winding torsion part may be formed by winding the lead wire while twisting the lead wire. . Moreover, it is not restricted to what uses a jig | tool, You may form the winding twist part 18 by winding the conducting wire 16 around the temperature sensor 20, twisting.
以上、本発明を実施するための形態について実施例を用いて説明したが、本発明はこうした実施例に何等限定されるものではなく、本発明の要旨を逸脱しない範囲内において、種々なる形態で実施し得ることは勿論である。 As mentioned above, although the form for implementing this invention was demonstrated using the Example, this invention is not limited at all to such an Example, In the range which does not deviate from the summary of this invention, it is with various forms.
