Description

本発明は、電動機や発電機等の回転電機のステータに関する。 The present invention relates to a stator of a rotating electric machine such as an electric motor or a generator.

電動機や発電機等の回転電機のステータは、円筒状をなすヨーク部の内周にティース部を周方向にわたって複数設けたステータコアの当該ティース部に、コイルを装着されたボビンがそれぞれ取り付けられている。このようなステータにおいては、回転電機の運転に伴って、コイルが発熱するため、当該コイルの温度を検出するサーミスタ等の温度検出素子が取り付けられている。 In the stator of a rotary electric machine such as an electric motor or a generator, a bobbin equipped with a coil is attached to the teeth portion of a stator core in which a plurality of teeth portions are provided on the inner circumference of a cylindrical yoke portion in the circumferential direction. .. In such a stator, since the coil generates heat as the rotary electric machine operates, a temperature detecting element such as a thermistor for detecting the temperature of the coil is attached.

例えば、下記特許文献１においては、コイルエンドのトンネル状の間隙に、温度検出素子を取り付けたガイドを挿入して固定することにより、コイルの温度を検出することを提案している。 For example, Patent Document 1 below proposes to detect the temperature of a coil by inserting and fixing a guide to which a temperature detecting element is attached in a tunnel-shaped gap at the end of the coil.

また、下記特許文献２においては、インシュレータの、ステータの径方向外側の板状の外端部に形成されたコイル溝に、温度検出素子を挿入して取り付けることにより、コイルの温度を検出することを提案している。 Further, in Patent Document 2 below, the temperature of the coil is detected by inserting and attaching a temperature detecting element to a coil groove formed in a plate-shaped outer end portion of the insulator on the radial outer side of the stator. Is proposing.

また、下記特許文献３においては、隣り合うティース部にそれぞれ取り付けられたコイルの一方に当接させるようにホルダを介して温度検出素子を当該コイルの間に挿入して取り付けることにより、コイルの温度を検出することを提案している。 Further, in Patent Document 3 below, the temperature of the coil is formed by inserting and attaching a temperature detection element between the coils so as to abut one of the coils attached to the adjacent teeth portions via a holder.

しかしながら、前記特許文献１で提案されている発明においては、コイルエンドのトンネル状の間隙に温度検出素子を取り付けることから、コイルを冷却するためにコイルエンドへ送給される冷却液による影響を受け易くなってしまい、コイルの温度を正確に計測することが難しくなってしまう。 However, in the invention proposed in Patent Document 1, since the temperature detection element is attached to the tunnel-shaped gap of the coil end, it is affected by the coolant supplied to the coil end to cool the coil. It becomes easy, and it becomes difficult to measure the temperature of the coil accurately.

また、前記特許文献２で提案されている発明においては、ステータの径方向外側、すなわち、ステータコアのヨーク部に当接する外端部のコイル溝に温度検出素子を取り付けることから、ステータコアからの熱による影響を受け易くなってしまうばかりか、冷却液がかかり易くなってしまい、コイルの温度を正確に計測することが難しくなってしまう。 Further, in the invention proposed in Patent Document 2, since the temperature detection element is attached to the outer side in the radial direction of the stator, that is, the coil groove at the outer end portion that contacts the yoke portion of the stator core, the heat from the stator core is used. Not only is it easily affected, but it is also easy for the coolant to be applied, making it difficult to accurately measure the coil temperature.

また、前記特許文献３で提案されている発明においては、隣り合うコイルの間に温度検出素子を取り付けることから、他方のコイルからの熱による影響を受け易くなってしまい、一方のコイルの温度を正確に計測することが難しくなってしまう。 Further, in the invention proposed in Patent Document 3, since the temperature detection element is attached between the adjacent coils, it is easily affected by the heat from the other coil, and the temperature of one coil is adjusted. It becomes difficult to measure accurately.

本発明は、上記課題を鑑みてなされたものであって、目的とするコイルの温度を正確に計測することが容易にできる回転電機のステータを提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a stator of a rotary electric machine capable of easily accurately measuring the temperature of a target coil.

前述した課題を解決するための、本発明に係る回転電機のステータは、円筒状をなすヨーク部の内周にティース部を周方向にわたって複数設けたステータコアの当該ティース部に、コイルを装着されたボビンをそれぞれ取り付けた回転電機のステータにおいて、前記ボビンが、前記コイルを装着される筒型をなす装着部と、前記装着部に装着された前記コイルを覆うように当該装着部の一方側の端部の周縁に形成されたフランジ部とを有してなる第一のボビン部材と、前記ステータコアの前記ティース部に内面側が嵌合すると共に前記第一のボビン部材の前記装着部の内側に外面側が嵌合する筒型をなす取付部と、前記第一のボビン部材の前記装着部に装着された前記コイルを覆うように、前記取付部の、前記装着部と嵌合される側と反対側の端部の周縁に形成されたフランジ部とを有してなる第二のボビン部材とを具えると共に、前記第一のボビン部材の前記フランジ部及び前記第二のボビン部材の前記フランジ部のうち前記ステータコアの径方向内側に位置する前記フランジ部の、前記第一のボビン部材の前記フランジ部及び前記第二のボビン部材の前記フランジ部のうち前記ステータコアの径方向外側に位置する前記フランジ部と対向する面側に、温度検出素子を包囲すると共に前記コイルに当接させるように内部に着脱可能に嵌合保持する保持溝が形成されていることを特徴とする。 In the stator of the rotary electric machine according to the present invention for solving the above-mentioned problems, a coil is mounted on the teeth portion of the stator core in which a plurality of teeth portions are provided on the inner circumference of the cylindrical yoke portion in the circumferential direction. In the stator of the rotary electric machine to which the bobbin is attached, one end of the mounting portion so that the bobbin covers the tubular mounting portion on which the coil is mounted and the coil mounted on the mounting portion. The inner surface side is fitted to the teeth portion of the stator core and the first bobbin member having a flange portion formed on the peripheral edge of the portion, and the outer surface side is inside the mounting portion of the first bobbin member. On the side of the mounting portion opposite to the side to be fitted with the mounting portion so as to cover the mounting portion having a tubular shape to be fitted and the coil mounted on the mounting portion of the first bobbin member. A second bobbin member having a flange portion formed on the peripheral edge of the end portion is provided, and of the flange portion of the first bobbin member and the flange portion of the second bobbin member. With the flange portion of the flange portion located on the radial inner side of the stator core, the flange portion of the first bobbin member and the flange portion of the second bobbin member located on the radial outer side of the stator core. It is characterized in that a holding groove is formed on the opposite surface side so as to surround the temperature detection element and to removably fit and hold the element so as to abut the coil.

また、本発明に係る回転電機のステータは、上述した回転電機のステータにおいて、前記ボビンの、前記ステータコアの周方向一方側又は他方側に位置する前記フランジ部に、前記保持溝が形成されていることを特徴とする。 Further, in the stator of the rotary electric machine according to the present invention, in the above-mentioned stator of the rotary electric machine, the holding groove is formed in the flange portion of the bobbin located on one side or the other side in the circumferential direction of the stator core. It is characterized by that.

また、本発明に係る回転電機のステータは、上述した回転電機のステータにおいて、前記コイルが、平角導線からなることを特徴とする。 Further, the stator of the rotary electric machine according to the present invention is characterized in that the coil of the stator of the rotary electric machine described above is made of a flat lead wire.

本発明に係る回転電機のステータによれば、保持溝に温度検出素子を取り付けることにより、温度検出素子が、ステータコアの径方向内側に位置付けられて、ボビンの保持溝に包囲されつつコイルに直接的に押し付けられながらコイルの温度を計測できることから、冷却液による影響や、ステータコアのヨーク部からの熱の影響や、隣りに位置するコイルからの熱の影響を受け難くなるので、目的とするコイルの温度を正確に計測することが容易にできる。 According to the stator of the rotary electric machine according to the present invention, by attaching the temperature detection element to the holding groove, the temperature detecting element is positioned inside the stator core in the radial direction, and is directly surrounded by the holding groove of the bobbin and directly connected to the coil. Since the temperature of the coil can be measured while being pressed against the coil, it is less susceptible to the effects of the coolant, the heat from the yoke of the stator core, and the heat from the adjacent coil. It is easy to measure the temperature accurately.

〈主な実施形態〉
本発明に係る回転電機のステータの主な実施形態を図１〜４に基づいて説明する。 <Main embodiment>
The main embodiments of the stator of the rotary electric machine according to the present invention will be described with reference to FIGS. 1 to 4.

図１に示すように、本実施形態に係るステータ１００は、円筒状をなすヨーク部１１１の内周に、軸方向に沿って長手方向を向けて径方向内側へ向かって突出するティース部１１２を周方向にわたって複数設けた鉄等の磁性材料からなるステータコア１１０と、前記ステータコア１１０の前記ティース部１１２にそれぞれ差し込まれて取り付けられた樹脂等の絶縁材料からなるボビン１２０と、前記ボビン１２０に装着された四角形断面をなす平角導線からなるコイル１３０とを備え、外周側がケーシングの内部に固定保持されると共に、内周側にロータが同軸をなして回転可能に配設されるようになっている。 As shown in FIG. 1, the stator 100 according to the present embodiment has a teeth portion 112 protruding inward in the radial direction in the longitudinal direction along the axial direction on the inner circumference of the cylindrical yoke portion 111. A stator core 110 made of a plurality of magnetic materials such as iron provided in the circumferential direction, a bobbin 120 made of an insulating material such as resin inserted and attached to the teeth portion 112 of the stator core 110, and a bobbin 120 attached to the bobbin 120. A coil 130 made of a flat lead wire having a rectangular cross section is provided, and the outer peripheral side is fixedly held inside the casing, and the rotor is coaxially arranged on the inner peripheral side so as to be rotatable.

前記ボビン１２０は、図２〜４に示すように、前記コイル１３０を装着される楕円形状の筒型をなす装着部１２１ａと、前記装着部１２１ａに装着された前記コイル１３０を覆うように当該装着部１２１ａの一方側の端部（ステータコア１１０の径方向外側へ位置する端部）の周縁に当該装着部１２１ａの径方向外側（ステータコア１１０の周方向で離反する方向）へ向かって突設された四角形状のフランジ部１２１ｂとを有してなる第一のボビン部材であるボビン本体１２１を具えると共に、前記ステータコア１１０の前記ティース部１１２に内面側が嵌合すると共に前記ボビン本体１２１の前記装着部１２１ａの内側に外面側が嵌合する楕円形状の筒型をなす取付部１２２ａと、前記ボビン本体１２１の前記装着部１２１ａに装着された前記コイル１３０を覆うように、前記取付部１２２ａの、前記装着部１２１ａと嵌合される側と反対側の端部（ステータコア１１０の径方向内側へ位置する端部）の周縁に当該取付部１２２ａの径方向外側（ステータコア１１０の周方向で離反する方向）へ向かって突設された四角形状のフランジ部１２２ｂとを有してなる第二のボビン部材であるボビン補助体１２２を具えている。 As shown in FIGS. 2 to 4, the bobbin 120 covers the mounting portion 121a having an elliptical tubular shape to which the coil 130 is mounted and the coil 130 mounted on the mounting portion 121a. It is projected toward the radially outer side of the mounting portion 121a (the direction away from the circumferential direction of the stator core 110) on the peripheral edge of one end of the portion 121a (the end located on the radial outer side of the stator core 110). A bobbin body 121, which is a first bobbin member having a quadrangular flange portion 121b, is provided, and the inner surface side of the stator core 110 is fitted to the teeth portion 112, and the mounting portion of the bobbin body 121. The mounting portion 122a is mounted so as to cover the mounting portion 122a having an elliptical shape in which the outer surface side is fitted inside the 121a and the coil 130 mounted on the mounting portion 121a of the bobbin body 121. To the radially outer side of the mounting portion 122a (the direction away from the circumferential direction of the stator core 110) on the peripheral edge of the end portion (the end portion located inward in the radial direction of the stator core 110) opposite to the side fitted with the portion 121a. It is provided with a bobbin auxiliary body 122 which is a second bobbin member having a quadrangular flange portion 122b projecting toward the bobbin.

つまり、前記ボビン１２０の前記ボビン本体１２１の前記装着部１２１ａに前記コイル１３０を装着して、当該ボビン本体１２１の当該装着部１２１ａに前記ボビン補助体１２２の前記取付部１２２ａを嵌合することにより、当該装着部１２１ａが、前記ステータコア１１０の周方向及び軸方向への当該コイル１３０のずれを防止しつつ、当該ボビン本体１２１及び当該ボビン保助体１２２の前記フランジ部１２１ｂ，１２２ｂが、当該コイル１３０に当接して当該コイル１３０を挟み込んで保持することにより、前記ステータコア１１０の径方向への当該コイル１３０のずれを防止することができるようになっているのである。 That is, by mounting the coil 130 on the mounting portion 121a of the bobbin main body 121 of the bobbin 120 and fitting the mounting portion 122a of the bobbin auxiliary body 122 to the mounting portion 121a of the bobbin main body 121. The mounting portion 121a prevents the coil 130 from shifting in the circumferential direction and the axial direction of the stator core 110, while the flange portions 121b and 122b of the bobbin body 121 and the bobbin assisting body 122 form the coil. By contacting the 130 and sandwiching and holding the coil 130, it is possible to prevent the coil 130 from being displaced in the radial direction of the stator core 110.

また、前記ボビン１２０は、前記ボビン本体１２１の前記フランジ部１２１ｂの幅方向（ステータコア１１０の周方向で離反する方向）一方側に前記装着部１２１ａの長手方向（ステータコア１１０の軸方向）に沿って設けられて当該装着部１２１ａの他方の端部側（ステータコア１１０の径方向内側へ位置する端部側）へ向かって突出するガイドブロックウォール１２１ｃを有している。 Further, the bobbin 120 is provided on one side in the width direction of the flange portion 121b of the bobbin main body 121 (direction separated in the circumferential direction of the stator core 110) along the longitudinal direction of the mounting portion 121a (axial direction of the stator core 110). It has a guide block wall 121c that is provided and projects toward the other end side of the mounting portion 121a (the end side located radially inward of the stator core 110).

このガイドブロックウォール１２１ｃは、前記ステータコア１１０の周方向の厚さである幅方向（前記装着部１２１ａの短手方向）の厚さ（長さ）が、前記フランジ部１２１ｂに連結している端部側である基端側（前記装着部１２１ａの前記一端側）である当該ステータコア１１０の径方向外側ほど、前記フランジ部１２１ｂから突出している端部側である先端側（前記装着部１２１ａの他端側）である当該ステータコア１１０の径方向内側よりも厚く（長く）なるように、当該ステータコア１１０の周方向外側の面である幅方向（前記装着部１２１ａの短手方向）外側の面がテーパ状に傾斜している。 The guide block wall 121c has an end portion in which the thickness (length) in the width direction (the lateral direction of the mounting portion 121a), which is the thickness in the circumferential direction of the stator core 110, is connected to the flange portion 121b. The radial outside of the stator core 110, which is the base end side (one end side of the mounting portion 121a), is the tip side (the other end of the mounting portion 121a), which is the end side protruding from the flange portion 121b. The outer surface in the width direction (the lateral direction of the mounting portion 121a), which is the outer surface in the circumferential direction of the stator core 110, is tapered so as to be thicker (longer) than the inner side in the radial direction of the stator core 110 (side). It is inclined to.

つまり、前記ステータコア１１０の各前記ティース部１１２に前記ボビン１２０の前記取付部１２２ａを差し込んでそれぞれ取り付けると、当該ステータコア１１０の周方向に隣り合う当該ティース部１１２の間に当該ボビン１２０の前記ガイドブロックウォール１２１ｃがそれぞれ位置することにより、隣り合う当該ボビン１２０の間を閉塞できる形状になっているのである（図１参照）。 That is, when the mounting portion 122a of the bobbin 120 is inserted into each of the teeth portions 112 of the stator core 110 and attached to each of the teeth portions 112, the guide block of the bobbin 120 is provided between the teeth portions 112 adjacent to each other in the circumferential direction of the stator core 110. By locating each of the walls 121c, the shape is such that the adjacent bobbins 120 can be closed (see FIG. 1).

さらに、前記ボビン１２０は、前記ボビン補助体１２２の前記フランジ部１２２ｂの幅方向（ステータコア１１０の周方向で離反する方向）他方側の、前記ボビン本体１２１の前記フランジ部１２２ａと対向する面側、すなわち、前記ステータコア１１０の径方向内側で前記コイル１３０と当接する面に、温度検出素子であるサーミスタ１４０の本体部１４１を包囲すると共に前記コイル１３０に当接させるように内部に着脱可能に嵌合保持する保持溝１２２ｃが前記取付部１２２ａの長手方向（ステータコア１１０の軸方向）に沿って長手方向を向けるようにして形成されている。 Further, the bobbin 120 is a surface side of the bobbin body 121 facing the flange portion 122a on the other side in the width direction of the flange portion 122b of the bobbin auxiliary body 122 (direction separated in the circumferential direction of the stator core 110). That is, the main body 141 of the thermista 140, which is a temperature detection element, is surrounded by the surface of the stator core 110 that comes into contact with the coil 130 in the radial direction, and is detachably fitted inside so as to come into contact with the coil 130. The holding groove 122c to be held is formed so as to face the longitudinal direction along the longitudinal direction (axial direction of the stator core 110) of the mounting portion 122a.

つまり、前記ボビン１２０の前記ボビン補助体１２２の前記保持溝１２２ｃ内にサーミスタ１４０の本体部１４１を差し込んで嵌合した後、前記コイル１３０を装着した前記ボビン本体１２１の前記装着部１２１ａに当該ボビン補助体１２２の前記取付部１２２ａを嵌合して、当該ボビン本体１２１の前記フランジ部１２１ｂを前記ステータコア１１０の前記ヨーク部１１１側に位置させるように当該ボビン１２０の前記取付部１２２ａを当該ステータコア１１０の前記ティース部１１２に嵌合すると、前記サーミスタ１４０の前記本体部１４１は、当該ステータコア１１０の径方向内側に位置付けられて当該ボビン補助体１２２の当該保持溝１２２ｃで周囲を覆われつつ前記コイル１３０に押し付けられるように当該ボビン１２０の当該保持溝１２２ｃ内に保持されるようになっているのである。 That is, after the main body 141 of the thermista 140 is inserted into the holding groove 122c of the bobbin auxiliary body 122 of the bobbin 120 and fitted, the bobbin is fitted into the mounting portion 121a of the bobbin main body 121 to which the coil 130 is mounted. The mounting portion 122a of the bobbin 120 is fitted to the mounting portion 122a of the bobbin 120 so that the flange portion 121b of the bobbin body 121 is positioned on the yoke portion 111 side of the stator core 110 by fitting the mounting portion 122a of the auxiliary body 122. When fitted to the teeth portion 112 of the above, the main body portion 141 of the thermista 140 is positioned inside the stator core 110 in the radial direction, and the coil 130 is covered with the holding groove 122c of the bobbin auxiliary body 122. The bobbin 120 is held in the holding groove 122c so as to be pressed against the bobbin 120.

このような本実施形態に係るステータ１００においては、回転電機の運転に伴って、前記コイル１３０が発熱すると、前記サーミスタ１４０の前記本体部１４１が、前記ステータコア１１０の径方向内側に位置付けられて前記ボビン１２０の前記保持溝１２２ｃに包囲されつつ当該コイル１３０に直接的に押し付けられながら当該コイル１３０の温度を計測することができる。 In the stator 100 according to the present embodiment, when the coil 130 generates heat as the rotary electric machine operates, the main body 141 of the thermistor 140 is positioned inside the stator core 110 in the radial direction. The temperature of the coil 130 can be measured while being surrounded by the holding groove 122c of the bobbin 120 and directly pressed against the coil 130.

このため、前記サーミスタ１４０の前記本体部１４１は、冷却液による影響や、前記ステータコア１１０の前記ヨーク部１１１からの熱の影響や、隣りに位置するコイル１３０からの熱の影響を受け難くなる。 Therefore, the main body 141 of the thermistor 140 is less susceptible to the influence of the coolant, the heat from the yoke 111 of the stator core 110, and the heat from the coil 130 located adjacent to the thermistor 140.

したがって、本実施形態に係るステータ１００によれば、目的とするコイル１３０の温度を正確に計測することが容易にできる。 Therefore, according to the stator 100 according to the present embodiment, it is possible to easily measure the temperature of the target coil 130 accurately.

また、前記コイル１３０を絶縁保持する前記ボビン１２０に前記保持溝１２２ｃを形成して前記サーミスタ１４０の前記本体部１４１を取付保持するようにしたことから、当該サーミスタ１４０の当該本体部１４１を保持するためだけの部材を用いる必要がないので、部品点数を減らして構造の簡略化を図ることができる。 Further, since the holding groove 122c is formed in the bobbin 120 that insulates and holds the coil 130 so that the main body portion 141 of the thermistor 140 is attached and held, the main body portion 141 of the thermistor 140 is held. Since it is not necessary to use only the members for the purpose, the number of parts can be reduced and the structure can be simplified.

また、前記ボビン１２０の、前記コイル１３０を挟持する前記フランジ部１２２ｂの前記フランジ部１２１ｂとの対向面に前記サーミスタ１４０の前記本体部１４１を取付保持するようにしたことから、当該本体部１４１を前記コイル１３０に確実に密接させることが容易にでき、当該コイル１３０の温度を正確に計測することがより確実にできる。 Further, since the main body 141 of the thermistor 140 is attached and held on the surface of the bobbin 120 facing the flange 121b of the flange 122b that sandwiches the coil 130, the main body 141 is attached. It can be easily brought into close contact with the coil 130, and the temperature of the coil 130 can be measured more reliably.

〈他の実施形態〉
