It has a substantially T-shaped appearance.

インシュレータ４３，４４の各被覆部４２は、図４に示すように、歯部４１ａの周方向側の側面を覆う壁面４２ａと、円弧部４１ｂの径方向外側の側面を覆う壁面４２ｂと、ステータコア４１の径方向内側の側面を覆う壁面４２ｃと、を備えて、壁面４２ｃ，４２ｃ間が分離された筒状に形成されている。   As shown in FIG. 4, each of the covering portions 42 of the insulators 43, 44 includes a wall surface 42 a that covers the side surface on the circumferential side of the tooth portion 41 a, a wall surface 42 b that covers the radially outer side surface of the arc portion 41 b, and the stator core 41.

そして、図２および図３に示すように、一方のインシュレータ４３をステータコア４１の軸方向一端部（図中上端部）に被覆部４２側から嵌合して取り付けるとともに、他方のインシュレータ４４をステータコア４１の軸方向他端部（図中下端部）に被覆部４２側から嵌合して取り付ける。   As shown in FIGS. 2 and 3, one insulator 43 is fitted and attached to one axial end portion (upper end portion in the drawing) of the stator core 41 from the cover portion 42 side, and the other insulator 44 is attached to the stator core 41. It is fitted and attached to the other axial end portion (lower end portion in the figure) from the side of the covering portion 42.

被覆部４２の突設高さは、インシュレータ４３，４４ともに、ステータコア４１の高さの半分よりも若干長い寸法に形成してあり、ステータコア４１の軸方向中間位置で、軸方向一方側のインシュレータ４３の被覆部４２の軸方向他方側の先端部と、軸方向他方側のインシュレータ４４の被覆部４２の軸方向一方側の先端部とを、相互に重ね合わせている。こうして外周を被覆部４２で被覆した歯部４１ａに、巻線４５が巻回される。すなわち、本実施形態では、軸方向の先端部同士が相互に嵌合された被覆部４２，４２およびそれらを含む二つのインシュレータ４３，４４によって、巻線４５と歯部４１ａ（ステータコア４１）との絶縁をより確実に確保することができる。   The projecting height of the covering portion 42 is formed so that both the insulators 43 and 44 are slightly longer than half of the height of the stator core 41, and the insulator 43 on one axial side of the stator core 41 is at an axially intermediate position. The tip end portion on the other axial side of the covering portion 42 and the tip end portion on the one axial side of the covering portion 42 of the insulator 44 on the other axial side are overlapped with each other. Thus, the winding 45 is wound around the tooth portion 41 a whose outer periphery is covered with the covering portion 42. That is, in this embodiment, the winding 45 and the tooth portion 41a (stator core 41) are formed by the covering portions 42 and 42 in which the tip portions in the axial direction are fitted to each other and the two insulators 43 and 44 including them. Insulation can be ensured more reliably.

ここで、巻線４５は、複数の歯部４１ａに連続して巻回される。すなわち、本実施形態では、全ての歯部４１ａを１本の導線によって順次巻回している。したがって、巻線４５の両端部４５ａ，４５ｂ（図３参照）が、相互に隣接する巻線４５，４５から突出した状態となっている。   Here, the winding 45 is continuously wound around the plurality of tooth portions 41a. In other words, in the present embodiment, all the tooth portions 41a are sequentially wound by one conductive wire. Accordingly, both end portions 45a and 45b (see FIG. 3) of the winding 45 are in a state of protruding from the windings 45 and 45 adjacent to each other.

ステータコア４１に対してポンプ２の反対側には、上述の巻線４５に制御電流を通電する制御基板４６を配置してある。本実施形態では、図１や図３に示すように、制御基板４６は、インシュレータ４４から軸方向に突設した複数の支持突起４４ａによって仮保持されており、その仮保持状態でモールド樹脂３１Ｍが射出されてステータコア４１に固定される。   On the opposite side of the pump 2 with respect to the stator core 41, a control board 46 for supplying a control current to the winding 45 is disposed. In this embodiment, as shown in FIGS. 1 and 3, the control board 46 is temporarily held by a plurality of support protrusions 44a protruding in the axial direction from the insulator 44, and the mold resin 31M is temporarily held in the temporarily held state. It is injected and fixed to the stator core 41.

また、ロータ５は、図１に示すように、分離板３２の円筒壁３２ｂ内に回転自在に配置される羽根車２３と、当該羽根車２３から一体に延設した回転筒５１と、この回転筒５１の周方向に等間隔をもって取り付けた複数のマグネット（図示せず）あるいは複数の極を備えたマグネット（図示せず）と、によって形成してある。ロータ収容室３４内で、ロータ５は、その内周に設けた軸受５２によって支軸３３に回転自在に支持される。   As shown in FIG. 1, the rotor 5 includes an impeller 23 that is rotatably disposed within a cylindrical wall 32 b of the separation plate 32, a rotating cylinder 51 that extends integrally from the impeller 23, and the rotation of the impeller 23. It is formed by a plurality of magnets (not shown) attached at equal intervals in the circumferential direction of the cylinder 51 or a magnet (not shown) provided with a plurality of poles. Within the rotor accommodating chamber 34, the rotor 5 is rotatably supported by the support shaft 33 by a bearing 52 provided on the inner periphery thereof.

したがって、本実施形態では、制御基板４６から巻線４５に制御電流が通電されることによりモータ３のロータ５が回転し、そして、このロータ５と一体の羽根車２３が回転してポンプ２を駆動し、吸入口２２ａから吸入した流体を吐出口２２ｂから吐出する。   Therefore, in this embodiment, when the control current is supplied from the control board 46 to the winding 45, the rotor 5 of the motor 3 rotates, and the impeller 23 integrated with the rotor 5 rotates to rotate the pump 2. Driven, the fluid sucked from the suction port 22a is discharged from the discharge port 22b.

ここで、本実施形態では、図１〜図３に示すように、巻線４５の両端部４５ａ，４５ｂを巻き付けるようにしてからげるとともに、その先端部６ａを制御基板４６に形成された孔４６ａ（図２参照）に挿入する２本のピン６を設けてある。そして、制御基板４６を配置した側のインシュレータ４４に、図３に示すように、このピン６を制御基板４６側に突出させた状態でそれぞれ固定する取付部６１を設け、この取付部６１にステータコア４１の外周に当接する補強リブ６２を設けてある。   Here, in the present embodiment, as shown in FIGS. 1 to 3, the both ends 45 a and 45 b of the winding 45 are curled and the tip 6 a is a hole formed in the control board 46. Two pins 6 to be inserted into 46a (see FIG. 2) are provided. Then, as shown in FIG. 3, the insulator 44 on the side where the control board 46 is disposed is provided with attachment portions 61 for fixing the pins 6 in a state of protruding toward the control board 46 side. Reinforcing ribs 62 that contact the outer periphery of 41 are provided.

さらに、インシュレータ４４には、制御基板４６側に向けて突設されて二つの取付部６１，６１間を連結する補強壁６３を設けてある。   Further, the insulator 44 is provided with a reinforcing wall 63 that protrudes toward the control board 46 and connects the two attachment portions 61 and 61.

取付部６１は、インシュレータ４４の制御基板４６側に、軸方向に沿って突設されており、インシュレータ４４の軸方向端部から所定厚さの矩形状に突出する座部６１ａと、この座部６１ａの先端中央部から突出する円柱状のピン挿入部６１ｂと、で形成してある。そして、ピン挿入部６１ｂの中心部にはピン６を圧入する挿入孔を形成し、その挿入孔にピン６を圧入固定してある。これら取付部６１は、隣接する一対の巻線４５に対応する部分に設けてある。   The mounting portion 61 is provided along the axial direction on the control board 46 side of the insulator 44, and a seat portion 61 a that protrudes in a rectangular shape with a predetermined thickness from the axial end portion of the insulator 44, and the seat portion It is formed with a cylindrical pin insertion portion 61b protruding from the center of the tip of 61a. An insertion hole for press-fitting the pin 6 is formed at the center of the pin insertion portion 61b, and the pin 6 is press-fitted and fixed in the insertion hole. These mounting portions 61 are provided at portions corresponding to adjacent pairs of windings 45.

補強リブ６２は、取付部６１の座部６１ａがインシュレータ４４に結合する基部から一体にステータコア４１の外周に沿って軸方向に所定厚さをもって所定長さＬだけ突出している。   The reinforcing rib 62 protrudes by a predetermined length L with a predetermined thickness in the axial direction along the outer periphery of the stator core 41 integrally from the base portion where the seat portion 61 a of the mounting portion 61 is coupled to the insulator 44.

補強壁６３は、インシュレータ４４の軸方向端部で、周方向に沿って略一定の厚さかつ高さで延設されており、その周方向両端部はそれぞれ取付部６１，６１と一体化されている。なお、本実施形態では、取付部６１，６１を、巻線４５同士の干渉を防止しつつ比較的近接させて設け、補強壁６３による剛性および強度の向上効果を高めてある。また、補強壁６３を周方向に略沿って屈曲させることで、剛性および強度の向上効果をより一層高めてある。   The reinforcing wall 63 extends in the axial direction end portion of the insulator 44 at a substantially constant thickness and height along the circumferential direction, and both circumferential end portions thereof are integrated with the mounting portions 61 and 61, respectively. ing. In the present embodiment, the attachment portions 61 and 61 are provided relatively close to each other while preventing interference between the windings 45, and the effect of improving the rigidity and strength by the reinforcing wall 63 is enhanced. Further, the reinforcing effect of the rigidity and strength is further enhanced by bending the reinforcing wall 63 substantially along the circumferential direction.

また、本実施形態では、図３に示すように、取付部６１を補強壁６３より制御基板４６側に突出させている。そして、巻線４５を、取付部６１より制御基板４６側に露出するピン６に巻回するようにしてある。   Further, in the present embodiment, as shown in FIG. 3, the attachment portion 61 protrudes from the reinforcing wall 63 toward the control board 46. The winding 45 is wound around the pin 6 exposed to the control board 46 side from the mounting portion 61.

なお、本実施形態のモータ３は、単相全波駆動方式のブラシレスモータであり、図４および図５に示すように、歯部４１ａ先端の円弧部４１ｂとロータ５の回転筒５１との隙間δは一定とはなっていない。例えば、図５に示すように、回転筒５１と円弧部４１ｂとの隙間δは、円弧部４１ｂの周方向一端部がａ、他端部がｂ（ａ＜ｂ）である。回転筒５１は、隙間δが大きい方から小さい方に向かって回転するので、本実施形態では隙間ｂ側から隙間ａ側に向かって回転することになる。   The motor 3 of the present embodiment is a single-phase full-wave drive type brushless motor, and as shown in FIGS. 4 and 5, the gap between the arc portion 41 b at the tip of the tooth portion 41 a and the rotating cylinder 51 of the rotor 5. δ is not constant. For example, as shown in FIG. 5, the gap δ between the rotating cylinder 51 and the arc portion 41b is such that one end in the circumferential direction of the arc portion 41b is a and the other end is b (a <b). Since the rotating cylinder 51 rotates from the larger gap δ toward the smaller one, in this embodiment, the rotating cylinder 51 rotates from the gap b side toward the gap a side.

このようなステータコア４１の歯部４１ａは左右非対称となるため、ステータコア４１の一端側のインシュレータ４３と他端側のインシュレータ４４の取付方向は、一方向のみ取付可能としなければならない。本実施形態では両インシュレータ４３，４４の被覆部４２は、上述したように、歯部４１ａの周方向側の側面を覆う壁面４２ａと、円弧部４１ｂの径方向外側の側面を覆う壁面４２ｂと、ステータコア４１の径方向内側の側面を覆う壁面４２ｃと、を備えて、構成してあり、円弧部４１ｂの周方向両端部の内面位置ａ′、ｂ′の位置をずらすことで、誤組み付けを防止してある。   Since the tooth portion 41a of the stator core 41 is asymmetrical in the left and right directions, the mounting direction of the insulator 43 on one end side and the insulator 44 on the other end side of the stator core 41 must be mountable only in one direction. In the present embodiment, as described above, the covering portions 42 of both the insulators 43 and 44 include a wall surface 42a that covers the circumferential side surface of the tooth portion 41a, a wall surface 42b that covers the radially outer side surface of the arc portion 41b, A wall surface 42c that covers the radially inner side surface of the stator core 41, and prevents misassembly by shifting the positions of the inner surface positions a 'and b' at both circumferential ends of the arc portion 41b. It is.

以上、説明したように、本実施形態では、巻線４５の両端部４５ａ，４５ｂをからげるとともに、その先端部６ａを制御基板４６に形成した孔４６ａに挿入する少なくとも２本のピン６を設け、インシュレータ４４に、制御基板４６側に向けて突設されてピン６を制御基板４６側に向けて突出させた状態でそれぞれ固定する取付部６１と、制御基板４６側に向けて突設されて複数の取付部６１，６１間を相互に連結する補強壁６３と、を設け、さらに、取付部６１に、ステータコア４１の外周に当接する補強リブ６２を設けた。したがって、インシュレータ４４と制御基板４６との相対的な位置ずれを抑制することができるとともに、ピン６を固定する取付部６１，６１を、補強リブ６２および／または補強壁６３によって効果的に補強することができるため、巻線４５を配索する際や、モールド樹脂３１Ｍを射出成形する際などに、巻線４５がからげられるピン６や取付部６１が当該巻線４５によって傾倒して位置ずれが生じるのを抑制することができる。したがって、巻線４５の配索作業を、より容易にかつより確実に行うことができるようになる。   As described above, in the present embodiment, at least two pins 6 for tangling both ends 45 a and 45 b of the winding 45 and inserting the tip end 6 a into the hole 46 a formed in the control board 46 are provided. And mounting portions 61 that protrude from the insulator 44 toward the control board 46 and fix the pins 6 in a state of protruding toward the control board 46, and project toward the control board 46. And a plurality of mounting portions 61 are connected to each other, and the mounting portion 61 is further provided with reinforcing ribs 62 that come into contact with the outer periphery of the stator core 41. Therefore, relative displacement between the insulator 44 and the control board 46 can be suppressed, and the mounting portions 61 and 61 for fixing the pin 6 are effectively reinforced by the reinforcing rib 62 and / or the reinforcing wall 63. Therefore, when the winding 45 is routed or when the molding resin 31M is injection-molded, the pin 6 and the mounting portion 61 where the winding 45 is twisted are tilted by the winding 45 and misaligned. Can be suppressed. Therefore, the wiring work of the winding 45 can be performed more easily and more reliably.

また、本実施形態では、取付部６１を、補強壁６３より制御基板４６側に突出させた。このため、補強壁６３の制御基板４６側にスペースを確保できる分、巻線４５をピン６にからげたり、工具等を用いて巻線４５の余長部分を切ったりする作業を行いやすくなる。   In the present embodiment, the mounting portion 61 is protruded from the reinforcing wall 63 toward the control board 46. For this reason, the space | interval which can secure the space by the side of the control board 46 of the reinforcement wall 63 becomes easy to perform the operation | work which winds the winding 45 to the pin 6, or cuts the extra length part of the winding 45 using a tool etc. .

また、本実施形態によれば、巻線４５の配索作業をより容易に行えて、製造のタクトタイムを短縮することができ、製造コストを低減することが可能なモータ一体型ポンプ１を得ることができる。   Moreover, according to this embodiment, the motor-integrated pump 1 can be obtained in which the winding work of the winding 45 can be performed more easily, the manufacturing tact time can be shortened, and the manufacturing cost can be reduced. be able to.
