  • the stator and the control board are disposed in the board housing portion.
  • the stator is configured to generate a magnetic field when supplied with a current.
  • the control board has a control circuit that controls the current supplied to the stator.
  • the stator generates a magnetic field when current is supplied from the control circuit. This magnetic field rotates the rotor. As the rotor rotates, the rotor impeller also rotates. The rotation of the impeller moves the liquid inside the pump chamber to the outer periphery of the pump chamber. The liquid that has moved to the outer periphery of the pump chamber is sent to the outside of the pump through the outlet. As the liquid inside the pump chamber is sent to the outside of the pump, the pressure inside the pump chamber decreases. As the pressure inside the pump chamber decreases, liquid is introduced into the pump chamber through the inlet. In this way, the pump transfers the liquid.
  • the stator when the stator is supplied with current, the stator generates heat. Further, when a current flows through the control circuit, the control circuit also generates heat. The heat generated by the stator and the control circuit causes the stator and the control circuit to malfunction. Therefore, it is necessary to release the heat generated by the stator and the control circuit to the outside of the casing.
  • the space between the control board and the casing is filled with a potting material having good heat conductivity.

More specifically, when the potting material is filled in the board housing portion, the control board can be sufficiently cooled, but contact failure occurs at the contact points connecting the control board and the terminals, wirings, and the like.

Description

モータ及びそのモータを備えたポンプ及びそのポンプを備えた液体循環装置Motor, pump provided with the motor, and liquid circulation device provided with the pump
　本発明は、モータ及びそのモータを備えたポンプ及びそのポンプを備えた液体循環装置に関する。特に、本発明は、モータに内蔵されモータの回転を制御する制御基板の取付技術に関するものである。 The present invention relates to a motor, a pump including the motor, and a liquid circulation device including the pump. In particular, the present invention relates to a technology for mounting a control board that is built in a motor and controls the rotation of the motor.
　日本公開特許公報特開２００８－１２８０７６号は、従来のポンプを開示している。従来のポンプは、モータで駆動するように構成されている。ポンプは、ケーシングと、ステータと、ロータと、制御基板とを有している。ケーシングは、流入口と、流出口と、基板収容部と、ポンプ室とを有している。基板収容室は、ポンプ室から隔離されている。ポンプ室は、流入口を流出口と連通させる。ロータは、ポンプ室の内部に収納されている。ロータは、磁場によって回転されるように構成されている。ロータは、羽根車を有している。ステータ及び制御基板は、基板収容部に配置されている。ステータは、電流の供給を受けたときに磁場を発生するように構成されている。制御基板は、ステータに供給される電流を制御する制御回路を有している。 Japanese Patent Laid-Open Publication No. 2008-128076 discloses a conventional pump. The conventional pump is configured to be driven by a motor. The pump has a casing, a stator, a rotor, and a control board. The casing has an inflow port, an outflow port, a substrate housing portion, and a pump chamber. The substrate storage chamber is isolated from the pump chamber. The pump chamber communicates the inlet with the outlet. The rotor is housed inside the pump chamber. The rotor is configured to be rotated by a magnetic field. The rotor has an impeller. The stator and the control board are disposed in the board housing portion. The stator is configured to generate a magnetic field when supplied with a current. The control board has a control circuit that controls the current supplied to the stator.
　ステータは、制御回路から電流が供給されたときに、磁場を発生する。この磁場は、ロータを回転させる。ロータが回転することにより、ロータの羽根車も回転する。羽根車の回転は、ポンプ室の内部の液体をポンプ室の外周部に移動させる。ポンプ室の外周に移動した液体は、流出口を介してポンプの外部に送られる。ポンプ室の内部の液体がポンプの外部に送られるのに伴って、ポンプ室の内部の圧力が低下する。ポンプ室の内部の圧力の低下に伴って、液体が、流入口を介してポンプ室の内部に導入される。このようにして、ポンプは液体を移送する。 The stator generates a magnetic field when current is supplied from the control circuit. This magnetic field rotates the rotor. As the rotor rotates, the rotor impeller also rotates. The rotation of the impeller moves the liquid inside the pump chamber to the outer periphery of the pump chamber. The liquid that has moved to the outer periphery of the pump chamber is sent to the outside of the pump through the outlet. As the liquid inside the pump chamber is sent to the outside of the pump, the pressure inside the pump chamber decreases. As the pressure inside the pump chamber decreases, liquid is introduced into the pump chamber through the inlet. In this way, the pump transfers the liquid.
　一方、ステータは、電流が供給されたとき、ステータは熱を発する。また、制御回路に電流が流れると、制御回路も熱を発する。ステータ及び制御回路が発する熱は、ステータや制御回路を誤動作させる。したがって、ステータ及び制御回路が発する熱を、ケーシングの外部に放出する必要がある。ケーシングの外部に熱を放出するために、制御基板とケーシングとの空間は、伝熱性の良好なポッティング材が充填されている。また、ステータとケーシングとの間の空間も、ポッティング材が充填されている。このポッティング材は、ステータや制御回路が発する熱を、ケーシングに伝達する。したがって、ステータや制御回路が発する熱は、ポッティング材を介して、ケーシングの外部に放出される。 On the other hand, when the stator is supplied with current, the stator generates heat. Further, when a current flows through the control circuit, the control circuit also generates heat. The heat generated by the stator and the control circuit causes the stator and the control circuit to malfunction. Therefore, it is necessary to release the heat generated by the stator and the control circuit to the outside of the casing. In order to release heat to the outside of the casing, the space between the control board and the casing is filled with a potting material having good heat conductivity. The space between the stator and the casing is also filled with a potting material. The potting material transmits heat generated by the stator and the control circuit to the casing. Therefore, the heat generated by the stator and the control circuit is released to the outside of the casing through the potting material.
　しかしながら、制御基板とケーシングの間にポッティング材を充填したことで、充填圧等で制御基板に位置ずれを生じる可能性があった。これにより、端子や配線等と制御基板の間にポッティング材が入り込むという問題があった。また、ポッティング材によって、あるいは半田が外れ、これにより接触不良を生じるという問題があった。なお、基板収容部は取付時に制御基板を内部に挿入するための開口を有している。開口に直交し基板収容部の内側へ向いた方向が取付方向となっている。制御基板は取付方向に沿って基板収容部に収容されることで取り付けられる。そして、開口は、蓋で閉鎖されるあるいは開口までポッティング材が充填されている。このポッティング材や蓋は、制御基板へ塵や埃等が付着することを防ぐ。また、制御基板が制御基板以外の部品と物理的に接触することにより破損することを防いでいる。 However, filling the potting material between the control board and the casing may cause displacement of the control board due to filling pressure or the like. As a result, there is a problem that the potting material enters between the terminal, the wiring, and the like and the control board. In addition, there is a problem that contact failure occurs due to the potting material or the solder coming off. Note that the board housing portion has an opening for inserting the control board into the interior at the time of mounting. The direction perpendicular to the opening and toward the inside of the substrate housing portion is the mounting direction. The control board is mounted by being housed in the board housing portion along the mounting direction. The opening is closed with a lid or filled with a potting material up to the opening. The potting material and lid prevent dust and dirt from adhering to the control board. Further, the control board is prevented from being damaged due to physical contact with components other than the control board.
　これに対して、ポッティング材を、ステータとケースの間にだけ充填することが提案されている。言い換えると、ポッティング材は、制御基板とケースの間に充填されていない。これにより、制御基板に接続された端子や配線等との間に接触不良が発生することを防止できる。つまり、ポッティング材を基板収容部に充填しないことで、制御基板に充填による圧力がかからない。その結果、ポッティング材の充填は、制御基板の位置ずれを生じさせない。このようにして、制御基板と端子や配線等の電気的な接続を保ち、接触不良の発生が回避される。このとき、制御基板及びケースの双方は、ゴム状のシート部材に平面で接触されている。制御基板に生じた熱がシート部材を介してケースから外部に放出されている。ステータに生じた熱は、同様にポッティング材を介してケースから外部に放出されている。 On the other hand, it has been proposed to fill the potting material only between the stator and the case. In other words, the potting material is not filled between the control board and the case. Thereby, it is possible to prevent a contact failure from occurring between the terminal and the wiring connected to the control board. That is, since the potting material is not filled in the substrate housing portion, the control substrate is not pressurized by filling. As a result, the filling of the potting material does not cause a displacement of the control board. In this way, electrical connection between the control board and the terminals, wirings, etc. is maintained, and occurrence of poor contact is avoided. At this time, both the control board and the case are in contact with the rubber-like sheet member in a plane. Heat generated in the control board is released from the case to the outside through the sheet member. Similarly, heat generated in the stator is released from the case to the outside through the potting material.

　しかしながら、基板収容部にポッティング材を充填しない場合、制御基板に生じた熱は、上記シート部材のみでケーシングに伝達されている。したがって、制御基板の放熱を十分に行うことができない。即ち、制御基板に熱による不具合を生じることがあった。詳しく説明すると、基板収容部にポッティング材を充填した場合、制御基板を十分に冷却できるが制御基板と端子や配線等を繋ぐ接点に接触不良を生じてしまう。基板収容部にポッティング材を充填しない場合、接触不良を回避できるが十分に冷却できなくなる。 However, when the potting material is not filled in the substrate housing portion, the heat generated in the control substrate is transmitted to the casing only by the sheet member. Therefore, it is not possible to sufficiently radiate the control board. That is, the control board may have a problem due to heat. More specifically, when the potting material is filled in the board housing portion, the control board can be sufficiently cooled, but contact failure occurs at the contact points connecting the control board and the terminals, wirings, and the like. When the potting material is not filled in the substrate housing portion, contact failure can be avoided, but sufficient cooling cannot be achieved.
　本発明は、上記課題を解決するためになされたものである。本発明の第１の目的は、制御基板が、ケーシング内の所定の位置に確実に配置されたモータを提供することである。第２の目的は、上述のモータを備えたポンプを提供することである。第３の目的は、前記ポンプを備えた液体循環装置を提供することである。 The present invention has been made to solve the above problems. A first object of the present invention is to provide a motor in which a control board is securely arranged at a predetermined position in a casing. The second object is to provide a pump equipped with the motor described above. A third object is to provide a liquid circulation device provided with the pump.
　上記課題を解決するために、本発明のモータは、ケーシングと、ステータと、ロータと、制御基板とを有する。ケーシングは、その内壁に囲まれた基板収容部を有している。ステータは、ケーシングに収納されている。ステータは、電流が供給されたときに磁場を発生するコイルを有している。ロータは、前記ケーシングに収納されている。ロータは、前記磁場によって回転されるように構成されており、これにより回転運動を発生する。制御基板は、前記基板収容部に配置されている。制御基板は、前記ステータへの前記電流の供給を制御する制御回路を有している。ケーシングは、第１係合部を有している。制御基板は、第２係合部を有している。前記第２係合部は、保持部を有している。第１係合部は、前記第２係合部の前記保持部と係合するように形成されており、これにより、前記制御基板が前記基板収容部の所定の位置に位置決めされる。 In order to solve the above problems, the motor of the present invention includes a casing, a stator, a rotor, and a control board. The casing has a substrate housing part surrounded by its inner wall. The stator is accommodated in the casing. The stator has a coil that generates a magnetic field when electric current is supplied. The rotor is housed in the casing. The rotor is configured to be rotated by the magnetic field, thereby generating a rotational motion. The control board is disposed in the board housing portion. The control board has a control circuit for controlling the supply of the current to the stator. The casing has a first engaging portion. The control board has a second engagement portion. The second engaging part has a holding part. The first engagement portion is formed to engage with the holding portion of the second engagement portion, and thereby the control board is positioned at a predetermined position of the substrate housing portion.
　この場合、第１係合部が第２係合部と係合したとき、制御基板は、基板収容部の所定の位置に位置決めされる。さらに、制御基板は、所定の位置に保持される。したがって、制御基板に端子や配線等を確実に接続して取り付けられる。そして、基板収容部内にポッティング材を充填しても制御基板に位置ずれが生じない。したがって、端子や配線等と制御基板の間に接触不良等の不具合が生じることを防止できる。更に、基板収容部にポッティング材を充填できる。これにより、制御基板で生じた熱がポッティング材を介してケースから外部に放出でき、放熱効率を向上することができる。 In this case, when the first engaging portion is engaged with the second engaging portion, the control substrate is positioned at a predetermined position of the substrate accommodating portion. Further, the control board is held at a predetermined position. Therefore, it is possible to securely connect the terminal and wiring to the control board. And even if the potting material is filled in the substrate housing portion, the control substrate is not displaced. Therefore, it is possible to prevent problems such as poor contact between the terminals and wirings and the control board. Furthermore, the potting material can be filled in the substrate housing portion. Thereby, the heat generated in the control board can be released from the case to the outside through the potting material, and the heat dissipation efficiency can be improved.

　本発明のモータ及びモータを備えたポンプを、添付の図面と共に説明する。なお、図６において、矢印Ｘで示されたＸ方向は、ポンプの厚み方向である。この矢印Ｘで示されたＸ方向は、制御基板３の取付方向Ａと反対の方向を示している。言い換えると、矢印で示されたＸ方向は、後述する開口部２１が向いている第１の方向と等しい。したがって、第１の方向と取付方向Ａとは並行である。 The motor of the present invention and a pump equipped with the motor will be described with reference to the accompanying drawings.

The X direction indicated by the arrow X indicates the direction opposite to the mounting direction A of the control board 3. In other words, the X direction indicated by the arrow is equal to a first direction in which an opening 21 to be described later faces.

　本発明のポンプは、モータを備える。モータは、ケーシングと、ステータ１３１と、ロータ１２１と、制御基板３と、ポッティング材９とを有している。ケーシングは、上部ケーシング１ａと、下部ケーシング１ｂと、蓋１７とを有している。上部ケーシング１ａは、下部ケーシング１ｂの上部に配置され、これにより、上部ケーシング１ａは、下部ケーシング１ｂと協働して、上部ケーシング１ａと下部ケーシング１ｂとの間にロータ収容部１２を形成する。ロータ収容部１２に収納されたロータ１２１は、上部ケーシング１ａの内壁と協働して、ポンプ室１１を形成する。また、上部ケーシング１ａは、流入口１１ａと流出口１１ｂとを有している。流入口１１ａは、ポンプ室１１と連通している。また、流出口１１ｂも、ポンプ室１１と連通している。一方、下部ケーシング１ｂは、その下面に凹部が形成されている。この凹部は、下方に向けられた開口部２１を有している。詳しく説明すると、凹部は、第１の方向に向けられた開口部２１を有している。言い換えると、凹部は、第１の方向と反対の取付方向に沿った深さを有する。蓋１７は、開口部２１をふさぐように、下部ケーシング１ｂに取り付けられる。これにより、下部ケーシング１ｂは、蓋１７と協働して、基板収容部２を形成する。したがって、下部ケーシング１ｂは、下部ケーシング１ｂの内壁に囲まれた基板収容部２を有する。基板収容部２は、円筒状の凹部として定義されるステータ収容部１３と、矩形状の凹部として定義される基板収容部２とで定義される。 The pump of the present invention includes a motor. The motor includes a casing, a stator 131, a rotor 121, a control board 3, and a potting material 9. The casing has an upper casing 1 a, a lower casing 1 b, and a lid 17. The upper casing 1a is disposed on the upper portion of the lower casing 1b, whereby the upper casing 1a cooperates with the lower casing 1b to form the rotor accommodating portion 12 between the upper casing 1a and the lower casing 1b. The rotor 121 accommodated in the rotor accommodating portion 12 forms the pump chamber 11 in cooperation with the inner wall of the upper casing 1a. Moreover, the upper casing 1a has an inflow port 11a and an outflow port 11b. The inflow port 11 a communicates with the pump chamber 11. The outflow port 11 b is also in communication with the pump chamber 11. On the other hand, the lower casing 1b has a recess formed on the lower surface thereof. This recess has an opening 21 directed downward. More specifically, the recess has an opening 21 directed in the first direction. In other words, the recess has a depth along the mounting direction opposite to the first direction. The lid 17 is attached to the lower casing 1b so as to close the opening 21. Thereby, the lower casing 1 b cooperates with the lid 17 to form the substrate housing portion 2. Therefore, the lower casing 1b has the substrate housing part 2 surrounded by the inner wall of the lower casing 1b. The substrate housing portion 2 is defined by a stator housing portion 13 defined as a cylindrical recess and a substrate housing portion 2 defined as a rectangular recess.
　ロータ１２１は、ケーシングに収容されている。より詳しく説明すると、ロータ１２１は、ロータ収容部１２の内部に配置されている。ロータ１２１は、永久磁石１２２と羽根車１１１とを有している。永久磁石１２２は、筒状に形成されており、これにより軸穴を有している。軸穴の方向は、永久磁石１２２の軸方向を定義している。永久磁石１２２は、軸方向の周りで回転可能に構成されている。したがって、永久磁石１２２の周りに磁場が発生したときに、永久磁石１２２は、軸方向の周りで回転する。その結果、永久磁石１２２が回転したときに、ロータ１２１は回転運動を発生する。羽根車１１１は、永久磁石１２２の上端に固定されている。したがって、永久磁石１２２が回転するとき、羽根車１１１も回転する。言い換えると、永久磁石１２２の回転運動は、羽根車１１１を回転させる。羽根車１１１は、回転板と複数のブレードとからなる。複数のブレードは、回転板の上面に配置されている。したがって、各ブレードは、隣接するブレードと協働して、螺旋状の流路を形成する。また、羽根車１１１の上面は、上部ケーシング１ａの下面と共に、液体流路を形成する。 The rotor 121 is accommodated in a casing. More specifically, the rotor 121 is disposed inside the rotor accommodating portion 12. The rotor 121 has a permanent magnet 122 and an impeller 111. The permanent magnet 122 is formed in a cylindrical shape, thereby having a shaft hole. The direction of the shaft hole defines the axial direction of the permanent magnet 122. The permanent magnet 122 is configured to be rotatable around the axial direction. Therefore, when a magnetic field is generated around the permanent magnet 122, the permanent magnet 122 rotates around the axial direction. As a result, when the permanent magnet 122 rotates, the rotor 121 generates a rotational motion. The impeller 111 is fixed to the upper end of the permanent magnet 122. Therefore, when the permanent magnet 122 rotates, the impeller 111 also rotates. In other words, the rotational movement of the permanent magnet 122 causes the impeller 111 to rotate. The impeller 111 includes a rotating plate and a plurality of blades. The plurality of blades are disposed on the upper surface of the rotating plate. Thus, each blade cooperates with an adjacent blade to form a spiral flow path. Moreover, the upper surface of the impeller 111 forms a liquid channel together with the lower surface of the upper casing 1a.
　ステータ１３１は、ステータ収容部１３内に配置されている。ステータ１３１は、電磁鋼板などを積層したステータコア１３２と、コイル１３３を有している。ステータコア１３２は、コイル１３３から、インシュレータ１３４によって電気的に絶縁されている。コイル１３３は、電流が供給されたときに磁場を発生するように構成されている。コイル１３３に供給される電流は、制御基板３に設けられた制御回路によって制御される。この制御基板３は、基板収容部２に配置されている。 The stator 131 is disposed in the stator housing portion 13. The stator 131 has a stator core 132 in which electromagnetic steel plates and the like are laminated, and a coil 133. The stator core 132 is electrically insulated from the coil 133 by an insulator 134. The coil 133 is configured to generate a magnetic field when a current is supplied. The current supplied to the coil 133 is controlled by a control circuit provided on the control board 3. The control board 3 is disposed in the board housing part 2.
　このように、本発明のポンプは、基板収容部２と、ステータ収容部１３と、ロータ収容部１２と、上記三つの収容部に収容される各部品とで構成されている。言い換えると、本発明のポンプは、基板収容部２と、ステータ収容部１３と、ロータ収容部１２と、上記三つの収容部に収容される各部品とで構成されている。そして、ステータ１３１及びロータ１２１は、羽根車１１１を回転させるための駆動源として機能する。言い換えると、ステータ１３１及びロータ１２１は、協働して、モータを定義する。そして、上記モータを備えたポンプは上部ケーシング１ａと下部ケーシング１ｂと蓋１７とにより、ロータ収容部１２と、ステータ収容部１３及び基板収容部２からなる収容部とに分かれている。そして、上記ステータ収容部１３及び基板収容部２は、ポッティング材９で充填されている。したがって、ステータ１３１及び制御基板３の全面をポッティング材９が覆っている。ポンプを使用するためにステータ１３１に電流が供給されると、ステータ１３１及び制御基板３から熱が生じる。ステータ１３１及び制御基板３から生じた熱は、ポッティング材９を介して下部ケーシング１ｂから外部へと放出されている。 As described above, the pump of the present invention includes the substrate housing portion 2, the stator housing portion 13, the rotor housing portion 12, and the components housed in the three housing portions. In other words, the pump according to the present invention includes the substrate housing portion 2, the stator housing portion 13, the rotor housing portion 12, and the components housed in the three housing portions. The stator 131 and the rotor 121 function as a drive source for rotating the impeller 111. In other words, the stator 131 and the rotor 121 cooperate to define a motor. The pump including the motor is divided into a rotor housing portion 12 and a housing portion including the stator housing portion 13 and the substrate housing portion 2 by the upper casing 1 a, the lower casing 1 b, and the lid 17. The stator accommodating portion 13 and the substrate accommodating portion 2 are filled with a potting material 9. Therefore, the potting material 9 covers the entire surface of the stator 131 and the control board 3. When a current is supplied to the stator 131 to use the pump, heat is generated from the stator 131 and the control board 3. The heat generated from the stator 131 and the control board 3 is released from the lower casing 1b to the outside through the potting material 9.
　ポッティング材９には、熱伝導率の高い材料を用いることが好ましい。熱伝導率の高い材料を用いることにより、ステータ１３１や制御基板３が発する熱を、ケーシングの外部に効率よく放出することができる。ポッティング材９は、例えば、熱伝導率の高いシリコン樹脂やエポキシ系樹脂が例示される。また、アルミナのフィラーが混合されたシリコン樹脂やエポキシ系樹脂も、ポッティング材９として採用することができる。アルミナのフィラーをシリコン樹脂やエポキシ系樹脂に含有させることにより、ポッティング材９の熱伝導率を向上することができる。 It is preferable to use a material having high thermal conductivity for the potting material 9. By using a material having high thermal conductivity, heat generated by the stator 131 and the control board 3 can be efficiently released to the outside of the casing. Examples of the potting material 9 include silicon resins and epoxy resins having high thermal conductivity. Further, a silicon resin or an epoxy resin mixed with an alumina filler can also be used as the potting material 9. The thermal conductivity of the potting material 9 can be improved by adding an alumina filler to the silicon resin or epoxy resin.
　また、上記制御基板３は、図１に示すように、開口部２１に直交する方向である取付方向Ａに沿って開口部２１から上記基板収容部２の底部２２側へと挿入される。これにより、制御基板３は、基板収容部２に取り付けられる。そして、制御基板３の第１の方向Ａ（第１の方向）に直交する端辺３２（長辺３２ａ）には、第２係合部８が設けられている。すなわち、制御基板３の取付方向Ａ（第１の方向）に直交する長辺３２ａは、第１の辺として定義され、この第１の辺には第２係合部８が設けられている。一方、基板収容部２の内壁２３には、第１係合部４が設けられている。詳しく説明すると、基板収容部２の内周壁２３１には、第１係合部４が設けられている。第１係合部４が第２係合部８と所定の保持位置で係合したとき、制御基板３が上記保持位置で基板収容部２に保持される。言い換えると、第１係合部４が第２係合部８と所定の保持位置で係合したとき、制御基板３が上記保持位置に位置するように、ケーシングに保持される。 Further, as shown in FIG. 1, the control board 3 is inserted from the opening 21 toward the bottom 22 of the board housing part 2 along the mounting direction A which is a direction orthogonal to the opening 21. As a result, the control board 3 is attached to the board housing part 2. The second engagement portion 8 is provided on the end side 32 (long side 32a) orthogonal to the first direction A (first direction) of the control board 3. That is, the long side 32a orthogonal to the mounting direction A (first direction) of the control board 3 is defined as the first side, and the second engagement portion 8 is provided on the first side. On the other hand, the first engaging portion 4 is provided on the inner wall 23 of the substrate housing portion 2. More specifically, the first engagement portion 4 is provided on the inner peripheral wall 231 of the substrate housing portion 2. When the first engaging portion 4 is engaged with the second engaging portion 8 at a predetermined holding position, the control substrate 3 is held by the substrate housing portion 2 at the holding position. In other words, when the first engaging portion 4 is engaged with the second engaging portion 8 at a predetermined holding position, the control board 3 is held by the casing so as to be located at the holding position.
　図２及び図３に示すように、上記第１係合部４は内壁２３から基板収容部２の内側に突出した突起部４１である。より詳しく説明すると、第１係合部４は、内周壁２３１から基板収容部２の内側に突出した突起部４１である。ここで、図２に示すＸ方向は、突起の長さ方向として定義される。したがって、突起は、突起の長さ方向に沿った長さを有する。より詳しく説明すると、突起の長さは、図３の符号１０１に沿った方向である。また、Ｙ方向は、突起の幅方向として定義される。したがって、突起は、突起の幅方向に沿った幅を有している。より詳しく説明すると、突起の幅は、図３の符号１０２に沿った方向である。突起の幅は、基板収容部２の内周面に沿っている。また、Ｚ方向は、突起の高さ方向として定義される。したがって、突起は、突起の高さ方向に沿った高さを有する。より詳しく説明すると、突起の高さは、符号１０２に沿った方向に垂直であり、且つ、符号１０１に沿った方向に垂直である。突起は、基板収容部２の内周面から基板収容部２の内側に向かう方向に沿った高さを有している。第２係合部８は、切欠８１である。即ち、制御基板３は、その縁に、切欠８１が設けられている。切欠８１は、制御基板３の厚み方向と平行な第１の方向に沿って貫通している。切欠８１は、制御基板３の厚み方向に垂直な第２断面を有している。この第２断面は、半円形状を有している。そして、第１係合部４である突起部４１とその第２係合部８である切欠８１は基板収容部２の保持位置で係合する。 As shown in FIGS. 2 and 3, the first engaging portion 4 is a protrusion 41 protruding from the inner wall 23 to the inside of the substrate housing portion 2. More specifically, the first engagement portion 4 is a protrusion 41 that protrudes from the inner peripheral wall 231 to the inside of the substrate housing portion 2. Here, the X direction shown in FIG. 2 is defined as the length direction of the protrusion. Accordingly, the protrusion has a length along the length direction of the protrusion. More specifically, the length of the protrusion is the direction along the reference numeral 101 in FIG. The Y direction is defined as the width direction of the protrusion. Therefore, the protrusion has a width along the width direction of the protrusion. More specifically, the width of the protrusion is the direction along the reference numeral 102 in FIG. The width of the protrusion is along the inner peripheral surface of the substrate housing portion 2. The Z direction is defined as the height direction of the protrusion. Therefore, the protrusion has a height along the height direction of the protrusion. More specifically, the height of the protrusion is perpendicular to the direction along the reference numeral 102 and perpendicular to the direction along the reference numeral 101. The protrusion has a height along the direction from the inner peripheral surface of the substrate housing portion 2 toward the inside of the substrate housing portion 2. The second engaging portion 8 is a notch 81. That is, the control board 3 is provided with a notch 81 at its edge. The notch 81 penetrates along a first direction parallel to the thickness direction of the control board 3. The notch 81 has a second cross section perpendicular to the thickness direction of the control board 3. The second cross section has a semicircular shape. Then, the protrusion 41 that is the first engagement portion 4 and the notch 81 that is the second engagement portion 8 are engaged at the holding position of the substrate housing portion 2.
　上記突起部４１は、保持部５と、ガイド部６と、基板受け部７とからなる。保持部５は、基板収容部２の保持位置に位置している。詳しく説明すると、保持部５は、基板収容部２の保持位置に対応する位置に位置する。保持部５は、突起部４１の長さ方向に沿って均一な幅を有している。保持部５は、上記切欠８１に係合する。ガイド部６は、保持部５から、第１の方向に向かって延出している。ガイド部６は、開口部２１から保持部５へ制御基板３をガイドする。基板受け部７は、保持部５に係合した制御基板３を保持位置に位置決めする。すなわち、基板受け部７は、保持部５が係合した制御基板３が、保持部５から取付方向に沿って上方に移動するのを妨げる。凹部は、取付方向に沿った深さ方向を有している。そして、保持部５は、深さ方向に直交する第１断面を有している。この保持部５の第１断面は、直線部５２と、直線部５２の先端に設けられた半円部５１とからなる。半円部５１は、切欠８１の直径及び円弧長と同じ寸法で突出している。直線部５２は、半円部５１の直径と同じ長さの幅を有している。また、直線部５２は、方形状に形成されている。これにより、保持部５は、半円と長方形とが組み合わさった第１断面を有している。また、保持部５の長さは、制御基板３の厚みよりも長く設定されている。しかしながら、保持部５の長さは、これに限定されない。すなわち、保持部５の長さは、制御基板３の厚みと同じか、それ以上であればよい。この構成により、切欠８１は、前記突起部４１の保持部５と係合するように、突起部４１の保持部５の半円部５１の円弧形状の周面に面接触する。これにより、制御基板３は、基板収容部２の保持位置に保持されている。このように、第１係合部４は、第２係合部８に対して面接触する。したがって、第１係合部４と第２係合部８との間の係合は、確実の制御基板３を保持位置に固定する。その結果、制御基板３が下部ケーシング１ｂに取り付けられたとき、制御基板３は下部ケーシング１ｂに対してがたつかない。 The protrusion 41 includes a holding portion 5, a guide portion 6, and a substrate receiving portion 7. The holding part 5 is located at the holding position of the substrate housing part 2. More specifically, the holding unit 5 is located at a position corresponding to the holding position of the substrate housing unit 2. The holding part 5 has a uniform width along the length direction of the protruding part 41. The holding part 5 is engaged with the notch 81. The guide part 6 extends from the holding part 5 in the first direction. The guide unit 6 guides the control board 3 from the opening 21 to the holding unit 5. The board receiving part 7 positions the control board 3 engaged with the holding part 5 at the holding position. That is, the board receiving part 7 prevents the control board 3 engaged with the holding part 5 from moving upward from the holding part 5 along the mounting direction. The recess has a depth direction along the mounting direction. And the holding | maintenance part 5 has a 1st cross section orthogonal to a depth direction. The first cross section of the holding portion 5 includes a straight portion 52 and a semicircular portion 51 provided at the tip of the straight portion 52. The semicircular portion 51 protrudes with the same dimensions as the diameter and arc length of the notch 81. The straight portion 52 has a width that is the same as the diameter of the semicircular portion 51. Moreover, the linear part 52 is formed in the square shape. Thereby, the holding | maintenance part 5 has the 1st cross section which the semicircle and the rectangle combined. The length of the holding unit 5 is set longer than the thickness of the control board 3. However, the length of the holding part 5 is not limited to this. That is, the length of the holding part 5 may be equal to or greater than the thickness of the control board 3. With this configuration, the notch 81 comes into surface contact with the arc-shaped peripheral surface of the semicircular portion 51 of the holding portion 5 of the protruding portion 41 so as to engage with the holding portion 5 of the protruding portion 41. Thereby, the control board 3 is held at the holding position of the board housing part 2. Thus, the first engagement portion 4 is in surface contact with the second engagement portion 8. Therefore, the engagement between the first engagement portion 4 and the second engagement portion 8 fixes the reliable control board 3 in the holding position. As a result, when the control board 3 is attached to the lower casing 1b, the control board 3 does not rattle against the lower casing 1b.
　上記ガイド部６は保持部５と同様に取付方向に垂直な第１断面を有しており、且つ、取付方向Ａに沿った長さを有している。言い換えると、ガイド部６は、凹部の深さ方向に沿った長さを有しており、且つ、凹部の深さ方向に垂直な第１断面を有している。ガイド部６の第１断面は、半円と長方形とが組み合わさった形を有している。そして、ガイド部６は、開口部２１に向かうに伴って、直線部６２の幅が連続的に徐々に小さくなっている。また、ガイド部６は、開口部２１に向かうに伴って、半円部６１の径が連続的に徐々に小さくなっている。したがって、ガイド部６の先端の幅は、ガイド部６の後端の幅よりも小さくなっている。より具体的に説明すると、ガイド部６の先端の幅は、ガイド部６の後端の幅の略半分である。ガイド部６の後端の幅１０３は、保持部５の幅１０２とほぼ同じとなっている。 The guide portion 6 has a first cross section perpendicular to the mounting direction, similar to the holding portion 5, and has a length along the mounting direction A. In other words, the guide portion 6 has a length along the depth direction of the recess and has a first cross section perpendicular to the depth direction of the recess. The first cross section of the guide portion 6 has a shape in which a semicircle and a rectangle are combined. And as the guide part 6 goes to the opening part 21, the width | variety of the linear part 62 is gradually reduced gradually. Moreover, the diameter of the semicircle part 61 becomes small gradually continuously as the guide part 6 goes to the opening part 21. As shown in FIG. Therefore, the width of the front end of the guide portion 6 is smaller than the width of the rear end of the guide portion 6. More specifically, the width of the front end of the guide portion 6 is substantially half of the width of the rear end of the guide portion 6. The width 103 at the rear end of the guide portion 6 is substantially the same as the width 102 of the holding portion 5.
　つまり、ガイド部６は第１の方向（取付方向Ａ）に沿って開口部２１側に向かって幅方向の寸法を狭くしたテーパを有したものである。ガイド部６は、幅の減少に応じて半円部６１も径が小さくなっている。したがって、突起部４１が基板収容部２の内側へ突出する寸法も開口部２１側に向かう程小さくなっている。これにより、制御基板３が開口部２１に位置するとき、切欠８１内にガイド部６の半円部６１の頂点が位置する。制御基板３が保持部５に近づく程切欠８１内で占める突起部４１の半円部６１の面積が増す。このように、ガイド部６が第１の方向（取付方向Ａ）に沿って幅の変化するテーパを有している。したがって、制御基板３は、ガイド部６により切欠８１が開口部２１から、テーパ形状でない保持部５までガイドされる。言い換えると、制御基板３は、ガイド部６により切欠８１が開口部２１から、均一な幅及び高さを有する保持部５までガイドされる。したがって、制御基板３を容易に基板収容部２の保持位置に取り付けることができる。 That is, the guide portion 6 has a taper in which the dimension in the width direction is narrowed toward the opening 21 along the first direction (mounting direction A). As for the guide part 6, the diameter of the semicircle part 61 is also small according to the reduction | decrease in width. Therefore, the dimension by which the protruding portion 41 protrudes to the inside of the substrate housing portion 2 is also reduced toward the opening portion 21 side. Thereby, when the control board 3 is positioned in the opening 21, the vertex of the semicircular portion 61 of the guide portion 6 is positioned in the notch 81. The area of the semicircular portion 61 of the protrusion 41 that occupies in the notch 81 increases as the control substrate 3 approaches the holding portion 5. Thus, the guide part 6 has a taper whose width changes along the first direction (attachment direction A). Therefore, the control board 3 is guided by the guide portion 6 from the opening portion 21 to the holding portion 5 that is not tapered. In other words, the control substrate 3 is guided by the guide portion 6 from the opening 21 to the holding portion 5 having a uniform width and height from the opening 21. Therefore, the control board 3 can be easily attached to the holding position of the board housing part 2.
　上記基板受け部７は開口部２１側を前方とした保持部５の直後に位置している。言い換えると、基板受け部７は、保持部５から見て開口部２１と反対側に位置しており、且つ、保持部５に隣接して設けられている。また、基板受け部７は、保持部５から見て、ガイド部６と反対側に位置しており、且つ、保持部５に隣接して設けられている。基板受け部７は、保持部５の半円部５１の直径より長い幅を有する平面視略長方形状の上面７１を備えている。切欠８１と保持部５が係合した際、上記略長方形状の上面７１に制御基板３の切欠８１を形成する部位が接触して載置される。つまり、基板受け部７は保持位置の直後に設けられているため、保持位置に保持された制御基板３の切欠８１を形成する周辺部位が基板受け部７の上面７１に接触して、保持位置に制御基板３を位置決め及び保持している。そのため、開口部２１側から挿入されて保持位置に取り付けられた制御基板３が保持位置より奥へ落ち込む等の位置ずれを基板受け部７が防止している。 The substrate receiving part 7 is located immediately after the holding part 5 with the opening 21 side in front. In other words, the substrate receiving portion 7 is located on the opposite side of the opening 21 as viewed from the holding portion 5 and is provided adjacent to the holding portion 5. The substrate receiving portion 7 is located on the opposite side of the guide portion 6 when viewed from the holding portion 5 and is provided adjacent to the holding portion 5. The substrate receiving portion 7 includes an upper surface 71 having a substantially rectangular shape in plan view and having a width longer than the diameter of the semicircular portion 51 of the holding portion 5. When the notch 81 and the holding part 5 are engaged, a portion where the notch 81 of the control board 3 is formed is brought into contact with the substantially rectangular upper surface 71. That is, since the substrate receiving portion 7 is provided immediately after the holding position, the peripheral portion forming the notch 81 of the control board 3 held at the holding position comes into contact with the upper surface 71 of the substrate receiving portion 7, so that the holding position is The control board 3 is positioned and held. For this reason, the substrate receiving portion 7 prevents a positional shift such that the control board 3 inserted from the opening 21 side and attached to the holding position falls down from the holding position.
　また、第１係合部４及び第２係合部８はコネクタ１４の電気配線１４１の近傍とステータ１３１の近傍の二箇所に設けられている。第１係合部４と第２係合部８とは、他の第１係合部４と第２係合部８に対して開口部２１側から見たときに非対称の位置に位置するように配置されている。詳しくは、制御基板３は、長辺３２ａと長辺３２ａに直交する短辺３２ｂを夫々端辺３２とした略長方形の矩形状である。即ち、長辺３２ａは、第１の辺として定義され、短辺３２ｂは第２の辺として定義される。上記制御基板３を収容する内壁２３により形成された基板収容部２も略長方形状となっている。そして、基板収容部２の対向する二つの長辺の内壁２３に夫々第１の突起部４１及び第２の突起部４１が設けられている。第１の突起部４１は、底部２２の対角線の中点を中心として他方の突起部４１の点対称となる位置よりずれて配置されている。そのため、夫々の突起部４１に係合する切欠８１も制御基板３の各長辺３２ａに位置し、且つ制御基板３中心の周りにおいて点対称からずれた位置で形成されている。これにより、制御基板３の板面と平行な平面上で矩形の略中央を中心に略１８０度回転させても第２係合部８が互いに他方の第１係合部４に係合しない。このような状態を、第１係合部４と第２係合部８とは、他の第１係合部４と第２係合部８に対して開口部２１側から見たときに非対称の位置として定義される。そして、基板収容部２のステータ収容部１３側の短辺に位置する内壁２３にも第１係合部４が設けられている。第１係合部４に係合する第２係合部８が制御基板３のステータ１３１側の短辺３２ｂに設けられている。 Further, the first engaging portion 4 and the second engaging portion 8 are provided at two locations near the electrical wiring 141 of the connector 14 and near the stator 131. The first engaging part 4 and the second engaging part 8 are positioned at asymmetric positions when viewed from the opening 21 side with respect to the other first engaging part 4 and the second engaging part 8. Is arranged. Specifically, the control board 3 has a substantially rectangular rectangular shape in which the long side 32a and the short side 32b orthogonal to the long side 32a are the end sides 32, respectively. That is, the long side 32a is defined as the first side, and the short side 32b is defined as the second side. The substrate accommodating portion 2 formed by the inner wall 23 that accommodates the control substrate 3 is also substantially rectangular. And the 1st projection part 41 and the 2nd projection part 41 are provided in the inner wall 23 of the two long sides which the board | substrate accommodating part 2 opposes, respectively. The first protrusion 41 is arranged so as to be shifted from the point-symmetrical position of the other protrusion 41 with the midpoint of the diagonal line of the bottom 22 as the center. Therefore, the notches 81 that engage with the respective protrusions 41 are also formed on the respective long sides 32a of the control board 3 and at positions shifted from point symmetry around the center of the control board 3. As a result, the second engaging portion 8 does not engage with the other first engaging portion 4 even if the second engaging portion 8 is rotated about 180 degrees around the substantially center of the rectangle on a plane parallel to the plate surface of the control board 3. In such a state, the first engaging portion 4 and the second engaging portion 8 are asymmetric when viewed from the opening 21 side with respect to the other first engaging portion 4 and the second engaging portion 8. Defined as the position of. The first engaging portion 4 is also provided on the inner wall 23 located on the short side of the substrate housing portion 2 on the stator housing portion 13 side. A second engagement portion 8 that engages with the first engagement portion 4 is provided on the short side 32 b of the control board 3 on the stator 131 side.
　このように、第１係合部４及び第２係合部８を対向する端辺３２に設けた際に、対向する端辺３２の一方に設けた第１係合部４及び第２係合部８を他方に設けた第１係合部４及び第２係合部８と非対称で配置されている。したがって、各第１係合部４が各第２係合部８と係合するときの制御基板３の配置は１つに限定される。これにより、制御基板３が板面の表裏や左右を逆向きとした状態等の誤った姿勢で基板収容部２に取り付けられることは防がれる。そして、直交する二つの端辺に設けた第１係合部４及び第２係合部８が制御基板３の板面に平行な平面上で回転させても設置位置が一致しない。したがって、上記回転方向における制御基板３の位置ずれも防止できる。これにより、正確に制御基板３を基板収容部２に配置して取り付けることができる。更に、矩形状の制御基板３は、二つの長辺３２ａと一つの短辺３２ｂの計三箇所に第２係合部８を備えている。係合部が２箇所の場合、係合部と対象の位置（基板上の対象の辺）方向にずれて取り付けられる可能性がある。係合部を３箇所にすることにより、このような問題は解消される。そして、制御基板３を基板収容部２に配置する際に短辺３２ｂの第２係合部８の有無により第２係合部８と第１係合部４の係合位置をより容易に作業者が認識できる。これにより、制御基板３が基板収容部２の誤った位置に取り付けられることを確実に防止することができる。なお、第１係合部４及び第２係合部８は複数の端辺に設けられていることのみが必要である。したがって、一つの端辺に二つ以上の第１係合部４及び第２係合部８を設けてもよい。各第１係合部４及び第２係合部８の設置位置は、コネクタ１４やステータ１３１の近傍に限らず適宜設計変更可能である。 Thus, when the 1st engaging part 4 and the 2nd engaging part 8 are provided in the opposing edge 32, the 1st engaging part 4 and the 2nd engaging provided in one of the opposing edges 32 The first engaging portion 4 and the second engaging portion 8 provided with the portion 8 on the other side are disposed asymmetrically. Therefore, the arrangement of the control board 3 when each first engagement portion 4 engages with each second engagement portion 8 is limited to one. This prevents the control board 3 from being attached to the board housing part 2 in a wrong posture such as a state where the front and back of the plate surface and the left and right sides are reversed. Even when the first engaging portion 4 and the second engaging portion 8 provided on two orthogonal sides are rotated on a plane parallel to the plate surface of the control board 3, the installation positions do not match. Therefore, the position shift of the control board 3 in the rotation direction can also be prevented. Thereby, the control board 3 can be correctly arranged and attached to the board | substrate accommodating part 2. FIG. Furthermore, the rectangular control board 3 includes the second engaging portions 8 at a total of three locations including two long sides 32a and one short side 32b. In the case where there are two engaging portions, there is a possibility that the engaging portion and the target position (target side on the substrate) are displaced and attached. Such a problem can be solved by using three engaging portions. When the control board 3 is arranged in the board housing part 2, the engagement positions of the second engagement part 8 and the first engagement part 4 can be more easily operated depending on the presence or absence of the second engagement part 8 having the short side 32b. Can recognize. Thereby, it can prevent reliably that the control board 3 is attached to the incorrect position of the board | substrate accommodating part 2. FIG. In addition, the 1st engaging part 4 and the 2nd engaging part 8 need only be provided in the some edge. Therefore, two or more first engaging portions 4 and second engaging portions 8 may be provided on one end side. The installation positions of the first engagement portions 4 and the second engagement portions 8 are not limited to the vicinity of the connector 14 and the stator 131, and can be appropriately changed in design.
　もちろん、制御基板３は各第２係合部８から各端辺３２の端部である角までの寸法が夫々異なる場合、四つの端辺３２に夫々第２係合部８を設けてもよい。つまり、板面に平行な平面上で板面の略中央で制御基板３を回転させた場合に、複数設けた第２係合部８のうち少なくとも一つの第２係合部８が他の第２係合部８用の第１係合部４に係合しない位置に設けてあればよい。そして、制御基板３の形状は長方形状に限られない。複数の第２係合部８の位置関係により制御基板３を誤った位置で基板収容部２に配置できないものであれば制御基板３の形状は正方形状のものであってもよい。 Of course, the control board 3 may be provided with the second engaging portions 8 on the four end sides 32 when the dimensions from the second engaging portions 8 to the corners which are the end portions of the end sides 32 are different. . That is, when the control board 3 is rotated at a substantially center of the plate surface on a plane parallel to the plate surface, at least one second engagement portion 8 among the plurality of second engagement portions 8 provided is the other second engagement portion 8. What is necessary is just to provide in the position which is not engaged with the 1st engaging part 4 for 2 engaging parts 8. FIG. And the shape of the control board 3 is not restricted to a rectangular shape. The shape of the control board 3 may be a square shape as long as the control board 3 cannot be disposed in the board housing part 2 at an incorrect position due to the positional relationship of the plurality of second engaging parts 8.
　また更に、図１及び図４に示すように、ステータ１３１及び制御基板３は、ねじ等の固定具１６により下部ケーシング１ｂの内側に取り付けられている。これにより、ステータ１３１及び制御基板３が開口部２１側へ移動することを防止している。詳しくは、基板収容部２の開口部２１の反対側に位置する底部２２に固定孔２４が複数設けられている。言い換えると、凹部の底に、固定孔２４が複数設けられている。固定孔２４に固定具１６が螺合することで、固定具１６が基板収容部２の底部２２に固定される。そして、固定具１６はステータ１３１の固定用フランジ部１３５の挿通孔（特に図示しない）や制御基板３の挿通孔（特に図示しない）を介して上記固定孔２４に固定されている。このようにして、ステータ１３１や制御基板３は、ケーシングの内側に固定される。 Furthermore, as shown in FIGS. 1 and 4, the stator 131 and the control board 3 are attached to the inside of the lower casing 1b by a fixture 16 such as a screw. This prevents the stator 131 and the control board 3 from moving toward the opening 21 side. Specifically, a plurality of fixing holes 24 are provided in the bottom portion 22 located on the opposite side of the opening portion 21 of the substrate housing portion 2. In other words, a plurality of fixing holes 24 are provided at the bottom of the recess. The fixing tool 16 is fixed to the bottom 22 of the substrate housing portion 2 by screwing the fixing tool 16 into the fixing hole 24. The fixture 16 is fixed to the fixing hole 24 through an insertion hole (not shown) of the fixing flange portion 135 of the stator 131 and an insertion hole (not shown) of the control board 3. In this way, the stator 131 and the control board 3 are fixed inside the casing.
　従って、第１係合部４と第２係合部８の係合に伴って、制御基板３は基板収容部２の保持位置で保持される。したがって、ポッティング材９が充填された場合であっても、制御基板３の位置ずれは防がれる。これにより、制御基板３と端子や配線等の間に接触不良等の不具合を生じることが防止される。そして、ガイド部６及び基板受け部７により確実に保持位置で第１係合部４と第２係合部８を係合させることができる。その結果、制御基板３の取付及び固定を容易に行うことができる。また、制御基板３と端子や配線等との接続も容易に且つ確実に行える。更に、第１係合部４及び第２係合部８を複数設ける際に非対称で配置されている。したがって、制御基板３の向きや表裏等を誤って配置することは防止される。このように、制御基板３の誤配置や位置ずれ等を防止して制御基板３の取付作業や配線等との接続作業を容易に且つ確実に行えるため、モータ及びポンプの生産性が向上する。また、第１係合部４を基板収容部２の内壁２３から突出した突起部４１とし、第２係合部８を切欠８１としている。そして、第１係合部４である突起は、第２係合部８である切欠８１と係合する。したがって、基板収容部２の保持位置まで制御基板３を第１の方向（取付方向Ａ）に沿って押込むだけで、第１係合部４と第２係合部８とを容易に係合させることができる。そして、制御基板３の第２係合部８が突起部４１の半円部５１と対をなす半円形状の第２断面を有する切欠８１である。したがって、制御基板３に第２係合部８を容易に形成することができる。したがって、生産費用を安価にすると共に、より生産性を向上している。 Therefore, the control board 3 is held at the holding position of the board housing part 2 with the engagement of the first engaging part 4 and the second engaging part 8. Therefore, even when the potting material 9 is filled, the positional deviation of the control board 3 is prevented. This prevents problems such as poor contact between the control board 3 and the terminals and wires. Then, the first engaging portion 4 and the second engaging portion 8 can be reliably engaged at the holding position by the guide portion 6 and the substrate receiving portion 7. As a result, the control board 3 can be easily attached and fixed. In addition, the control board 3 can be easily and reliably connected to the terminals and wirings. Furthermore, when the plurality of first engaging portions 4 and second engaging portions 8 are provided, they are arranged asymmetrically. Therefore, it is possible to prevent the control board 3 from being misplaced in the direction, front and back, and the like. As described above, the misplacement and displacement of the control board 3 can be prevented, and the attachment work of the control board 3 and the connection work with the wiring can be easily and reliably performed, so that the productivity of the motor and the pump is improved. Further, the first engaging portion 4 is a protrusion 41 protruding from the inner wall 23 of the substrate housing portion 2, and the second engaging portion 8 is a notch 81. Then, the protrusion that is the first engaging portion 4 engages with the notch 81 that is the second engaging portion 8. Therefore, the first engagement portion 4 and the second engagement portion 8 can be easily engaged simply by pushing the control substrate 3 along the first direction (attachment direction A) to the holding position of the substrate housing portion 2. Can be made. The second engagement portion 8 of the control board 3 is a notch 81 having a semicircular second cross section that forms a pair with the semicircular portion 51 of the protrusion 41. Therefore, the second engagement portion 8 can be easily formed on the control board 3. Therefore, the production cost is reduced and the productivity is further improved.
　また、ステータ１３１を固定具１６で下部ケーシング１ｂに取り付けたことで、ポッティング材９の充填時にステータ１３１に位置ずれが生じることを防止している。そのため、ステータ１３１のカラゲ端子１５等が制御基板３のスルーホールへ容易に且つ確実に挿通することができる。これにより、カラゲ端子１５と接点との間の接触不良を防ぐことができる。そして、制御基板３を固定具１６で基板収容部２に取り付けたことで、下部ケーシング１ｂの外部からの衝撃で制御基板３が開口部２１側へ浮くことを防止することができる。加えて、突起部４１の基板受け部７により、制御基板３が保持位置より奥へ落ち込むことを防止している。そのため、制御基板３と端子や配線等を接続した半田にクラックを生じる等の不具合の発生を防止できる。その結果、安全性及び寿命のより向上したモータ及びポンプとなっている。そして、第１係合部４と第２係合部８の係合により制御基板３が位置決めされている。したがって、制御基板３の挿通孔と、基板収容部２の固定孔２４を容易に且つ確実に連通して取り付けられる。そのため、制御基板３を下部ケーシング１ｂに強固に固定できる。その結果、下部ケーシング１ｂの外部からの衝撃に対して制御基板３がより位置ずれを生じ難いものとなっている。 Further, the stator 131 is attached to the lower casing 1b with the fixture 16, so that the stator 131 is prevented from being displaced when the potting material 9 is filled. Therefore, the carage terminal 15 and the like of the stator 131 can be easily and reliably inserted into the through hole of the control board 3. Thereby, the contact failure between the carragage terminal 15 and a contact can be prevented. And by attaching the control board 3 to the board | substrate accommodating part 2 with the fixing tool 16, it can prevent that the control board 3 floats to the opening part 21 side by the impact from the outside of the lower casing 1b. In addition, the substrate receiving portion 7 of the protrusion 41 prevents the control substrate 3 from falling from the holding position. For this reason, it is possible to prevent the occurrence of defects such as cracks in the solder connecting the control board 3 and the terminals and wires. As a result, the motor and pump have improved safety and life. The control board 3 is positioned by the engagement of the first engagement portion 4 and the second engagement portion 8. Therefore, the insertion hole of the control board 3 and the fixing hole 24 of the board housing part 2 are easily and reliably connected and attached. Therefore, the control board 3 can be firmly fixed to the lower casing 1b. As a result, the control board 3 is less likely to be displaced due to an impact from the outside of the lower casing 1b.

　また、第１係合部は、ケーシングの内面から基板収容部に向かって突出している突起である。第２係合部は、前記制御基板の縁に形成された切欠である。したがって、第１係合部を第２係合部に対して容易に係合させることができる。 Further, the first engaging part is a protrusion protruding from the inner surface of the casing toward the substrate housing part. The second engaging portion is a notch formed at the edge of the control board. Therefore, the first engaging portion can be easily engaged with the second engaging portion.
　また、基板収容部は、内周面を有しており、且つ、第１の方向に開口している。突起は、第１の方向に沿った長さと、前記基板収容部の内周面に沿った幅と、前記基板収容部の内周面から基板収容部の内側に向かう方向に沿った高さとを有している。したがって、制御基板を第１の方向に並行な方向に沿って基板収容部の内部に導入することができる。これにより、制御基板を、基板収容部内に容易に配置することができる。 Further, the substrate housing portion has an inner peripheral surface and is open in the first direction. The protrusion has a length along the first direction, a width along the inner peripheral surface of the substrate housing portion, and a height along the direction from the inner peripheral surface of the substrate housing portion toward the inside of the substrate housing portion.

　また、突起は、さらにガイド部を有している。ガイド部は、前記保持部から第１の方向に向かって延出している。ガイド部は、前記第１の方向に向かうに伴って前記幅が狭くなるテーパ形状を有している。これにより、基板収容部に制御基板を円滑に導入することができる。 Also, the protrusion further has a guide part. The guide portion extends from the holding portion in the first direction. The guide portion has a tapered shape in which the width becomes narrower as it goes in the first direction. Thereby, the control board can be smoothly introduced into the board housing portion.
　また、保持部の幅は、前記第１の方向に沿った前記保持部の全長にわたって、均一である。したがって、第１係合部と第２係合部とが係合したとき、制御基板を基板収容部の所定の位置に固定することができる。すなわち、制御基板が、第１の方向と垂直な方向においてがたつくことが防がれる。 Further, the width of the holding portion is uniform over the entire length of the holding portion along the first direction. Therefore, when the first engaging portion and the second engaging portion are engaged, the control substrate can be fixed at a predetermined position of the substrate housing portion. In other words, it is possible to prevent the control board from rattling in a direction perpendicular to the first direction.
　また、ケーシングは、さらに基板受け部を有している。基板受け部は、前記保持部の直後に配置されている。突起が前記切欠と係合しているときに、前記基板受け部は前記制御基板と接触している。したがって、制御基板を確実に基板収容部の所定の位置に位置させることができる。 The casing further has a substrate receiving portion. The substrate receiving part is disposed immediately after the holding part. When the protrusion is engaged with the notch, the substrate receiving portion is in contact with the control substrate. Therefore, the control board can be reliably positioned at a predetermined position of the board housing portion.
　また、ケーシングは、さらに基板受け部を有している。基板受け部は、前記保持部をから見て、前記ガイド部と反対側に位置している。突起が前記切欠と係合しているときに、前記基板受け部は前記制御基板と接触している。したがって、基盤収容部に制御基板を円滑に導入することができる。さらに、制御基板を確実に基板収容部の所定の位置に位置させることができる。 The casing further has a substrate receiving portion. The substrate receiving part is located on the side opposite to the guide part when viewed from the holding part. When the protrusion is engaged with the notch, the substrate receiving portion is in contact with the control substrate. Therefore, the control board can be smoothly introduced into the base housing portion. Furthermore, the control board can be reliably positioned at a predetermined position of the board housing portion.
　また、突起は、突起の長さ方向に直交する第１断面を有している。第１断面は、第１形状を有している。第１形状は、直線部分と直線部分の先端に設けられた半円部分とからなる。切欠は、前記長さ方向に直交する第２断面を有している。第２断面は、第３形状を有している。第３形状は、直線部分と、直線部分の先端に設けられた半円部分とからなる。したがって、突起と切欠との形状を容易に形成することができる。 The protrusion has a first cross section orthogonal to the length direction of the protrusion.
