線圈12係***於積層鐵芯11之插槽。線圈12之線圈端部12a、12b係從積層鐵芯11之端面11a、11b突出。 The coil 12 is inserted into a slot of the laminated core 11. The coil end portions 12a and 12b of the coil 12 protrude from the end faces 11a and 11b of the laminated core 11.
罩蓋13係利用電阻值及熱傳導率比樹脂部14高之樹脂材料而形成。罩蓋13係形成為圓筒狀。罩蓋13係具有形成在中心軸AX之軸線方向之兩端的端面13a、13b、及沿著中心軸AX之軸周圍方向形成之內周面13c及外周面13d。關於端面13a、13b,係對於中心軸AX之軸線方向,將積層鐵芯11側之端面定為端面13a,將與積層鐵芯11側之端面不同之端面定為端面13b。 The cover 13 is formed of a resin material having a resistance value and a thermal conductivity higher than that of the resin portion 14. The cover 13 is formed in a cylindrical shape. The cover 13 has end faces 13a and 13b formed at both ends in the axial direction of the central axis AX, and an inner peripheral surface 13c and an outer peripheral surface 13d formed along the axial direction of the central axis AX. In the axial direction of the central axis AX, the end faces 13a on the side of the laminated core 11 are defined as the end faces 13a, and the end faces different from the end faces on the side of the laminated core 11 are defined as the end faces 13b.
端面13a、13b係形成平面狀。罩蓋13係在端面13a抵接於積層鐵芯11之端面11a、11b的狀態下配置。在端面13a形成有供卡合銷15***之***孔13e。***孔13e係形成為卡合銷15之長度,亦即中心軸AX之軸線方向的尺寸以上之深度。***孔13e係於中心軸AX之軸周圍方向配置複數個。***孔13e係設置於將罩蓋13配置在端面11a、11b上時與***孔11e相對向之位置。 The end faces 13a and 13b are formed in a planar shape. The cover 13 is disposed in a state in which the end surface 13a is in contact with the end faces 11a and 11b of the laminated core 11. An insertion hole 13e into which the engagement pin 15 is inserted is formed in the end surface 13a. The insertion hole 13e is formed to have a length of the engaging pin 15, that is, a depth equal to or larger than the dimension of the central axis AX in the axial direction. The insertion holes 13e are arranged in plural in the direction around the axis of the central axis AX. The insertion hole 13e is provided at a position facing the insertion hole 11e when the cover 13 is placed on the end faces 11a and 11b.
罩蓋13係包圍線圈端部12a、12b而配置。罩蓋13之內周面13c係與線圈端部12a、12b相對向。罩蓋13之外周面13d係與積層鐵芯11之外周面11d一致。因此,電動機定子10的外徑係從積層鐵芯11至罩蓋13成為相同。 The cover 13 is disposed to surround the coil end portions 12a and 12b. The inner peripheral surface 13c of the cover 13 faces the coil end portions 12a and 12b. The outer peripheral surface 13d of the cover 13 coincides with the outer peripheral surface 11d of the laminated core 11. Therefore, the outer diameter of the motor stator 10 is the same from the laminated core 11 to the cover 13.
樹脂部14係覆蓋線圈端部12a、12b,並且以填補端面11a、11b上之空間的狀態,形成為圓環狀。樹脂部14係具有:形成在中心軸AX之軸線方向之兩側的端面14a、14b;及沿著中心軸AX之軸周圍方向形成之內周面14c及外周面14d。 The resin portion 14 covers the coil end portions 12a and 12b, and is formed in an annular shape in a state of filling the space on the end faces 11a and 11b. The resin portion 14 has end faces 14a and 14b formed on both sides in the axial direction of the central axis AX, and an inner peripheral surface 14c and an outer peripheral surface 14d formed along the axial direction of the central axis AX.
端面14a係接著在端面11a、11b。並且,外周面14d係接著在罩蓋13之內周面13c。藉此,樹脂部14係將積層鐵芯11之端面11a、11b與罩蓋13予以接著固定。端面14b係與罩蓋13之端面13b形成為齊平。內周面14c係與積層鐵芯11之內周面11c一致。 The end face 14a is followed by the end faces 11a, 11b. Further, the outer peripheral surface 14d is followed by the inner peripheral surface 13c of the cover 13. Thereby, the resin portion 14 fixes the end faces 11a and 11b of the laminated core 11 and the cover 13 in the same manner. The end surface 14b is formed flush with the end surface 13b of the cover 13. The inner circumferential surface 14c coincides with the inner circumferential surface 11c of the laminated iron core 11.
卡合銷15係設置在每個相對向之***孔11e及***孔13e之組。卡合銷15之一端係***於積層鐵芯11之***孔11e,其另一端係***於罩蓋13之***孔13e。在卡合銷15***於***孔11e及***孔13e之狀態下,積層鐵芯11與罩蓋13係在與端面11a、11b平行之方向,透過卡合銷15而卡合。因此,藉由設置卡合銷15而限制積層鐵芯11與罩蓋13之間的朝沿著端面11a、11b之方向的相對移動。此外,積層鐵芯11與罩蓋13之間的相對移動,亦包含於中心軸AX之軸周圍方向的相對旋轉移 動。 The engaging pin 15 is provided in a group of each of the insertion holes 11e and the insertion holes 13e. One end of the engaging pin 15 is inserted into the insertion hole 11e of the laminated core 11, and the other end thereof is inserted into the insertion hole 13e of the cover 13. In a state in which the engaging pin 15 is inserted into the insertion hole 11e and the insertion hole 13e, the laminated core 11 and the cover 13 are engaged with each other in the direction parallel to the end faces 11a and 11b, and are engaged by the engaging pin 15. Therefore, the relative movement between the laminated iron core 11 and the cover 13 in the direction along the end faces 11a, 11b is restricted by providing the engaging pin 15. In addition, the relative movement between the laminated core 11 and the cover 13 also includes relative rotational movement in the direction around the axis of the central axis AX. move.
在製造上述之電動機定子10時,首先,對於積層鐵芯11之端面11a、11b,在包圍線圈端部12a、12b之狀態下,配置罩蓋13。在配置罩蓋13之際,將卡合銷15之一方端部***於積層鐵芯11之***孔11e,且將另一方端部***於***孔13e。藉此,透過卡合銷15,將積層鐵芯11與罩蓋13卡合於沿著端面11a、11b之方向。因此,限制積層鐵芯11及罩蓋13朝沿著端面11a、11b之方向之相對移動。 When manufacturing the above-described motor stator 10, first, the cover 13 is placed in the state in which the end faces 11a and 11b of the laminated core 11 are surrounded by the coil end portions 12a and 12b. When the cover 13 is placed, one end of the engaging pin 15 is inserted into the insertion hole 11e of the laminated core 11, and the other end is inserted into the insertion hole 13e. Thereby, the laminated core 11 and the cover 13 are engaged with the cover pin 15 in the direction along the end faces 11a and 11b. Therefore, the relative movement of the laminated iron core 11 and the cover 13 in the direction along the end faces 11a, 11b is restricted.
接著,在積層鐵芯11之內部***圓筒構件或圓柱構件,且藉由板狀構件來擋住端面11b側之罩蓋13的端面13b。在此狀態下,於端面11a側之罩蓋13之內側流入熔融的樹脂。熔融之樹脂係經由線圈12而供給至端面11b側。藉由在樹脂填充於端面11a上之空間及端面11b上之空間的狀態下使熔融之樹脂硬化,而形成樹脂部14。藉由形成樹脂部14,而以樹脂部14覆蓋線圈端部12a、12b。並且,將積層鐵芯11及罩蓋13接著並固定。 Next, a cylindrical member or a cylindrical member is inserted into the laminated core 11, and the end surface 13b of the cover 13 on the end surface 11b side is blocked by the plate member. In this state, the molten resin flows into the inside of the cover 13 on the end surface 11a side. The molten resin is supplied to the end surface 11b side via the coil 12. The resin portion 14 is formed by curing the molten resin in a state where the resin is filled in the space on the end surface 11a and the space on the end surface 11b. The resin portion 14 is formed to cover the coil end portions 12a and 12b with the resin portion 14. Then, the laminated iron core 11 and the cover 13 are attached and fixed.
在將電動機予以高輸出化或高轉矩化時,來自電動機定子10之發熱量會變大。在實施形態1之於積層鐵芯11***有線圈12之構成的電動機定子10中,來自線圈12之發熱量會變大。 When the motor is increased in output or high in torque, the amount of heat generated from the motor stator 10 becomes large. In the motor stator 10 having the configuration in which the coil 12 is inserted into the laminated core 11 in the first embodiment, the amount of heat generated from the coil 12 is increased.
相對於此,在實施形態1中,電動機定子10之構成係具有在覆蓋線圈端部12a、12b之外周的狀態下配置之罩蓋13,且在線圈端部12a、12b與罩蓋13之間 填充有樹脂部14。藉此,可有效率地將線圈12產生之熱,透過樹脂部14及罩蓋13從線圈端部12a、12b排出至外部。 On the other hand, in the first embodiment, the motor stator 10 has a cover 13 that is disposed in a state of covering the outer circumferences of the coil end portions 12a and 12b, and between the coil end portions 12a and 12b and the cover 13 The resin portion 14 is filled. Thereby, the heat generated by the coil 12 can be efficiently discharged from the coil end portions 12a and 12b to the outside through the resin portion 14 and the cover 13.
再者,在實施形態1中,由於設置有用以卡合積層鐵芯11與罩蓋13且限制積層鐵芯11與罩蓋13之間的朝沿著端面11a、11b之方向的相對移動之卡合銷15,因此能以簡單之構成抑制形成樹脂部14時之積層鐵芯11與罩蓋13之間的相對移動。因此,無須嵌合積層鐵芯11與罩蓋13,亦無須進行螺絲結合,故可抑制生產性之降低。 Further, in the first embodiment, a card for engaging the laminated iron core 11 and the cover 13 and restricting the relative movement between the laminated iron core 11 and the cover 13 in the direction along the end faces 11a and 11b is provided. Since the pin 15 is engaged, the relative movement between the laminated core 11 and the cover 13 when the resin portion 14 is formed can be suppressed with a simple configuration. Therefore, it is not necessary to fit the laminated core 11 and the cover 13, and it is not necessary to perform screwing, so that the decrease in productivity can be suppressed.
如以上所述,依據實施形態1,可得到一種抑制生產性之降低,可實現小型化,且將線圈12所產生之熱有效率地排出之電動機定子10。 As described above, according to the first embodiment, it is possible to obtain the motor stator 10 which can reduce the productivity, reduce the size, and efficiently discharge the heat generated by the coil 12.
再者,由於罩蓋13係利用電阻值比樹脂部14高之樹脂材料而形成,因此能夠以罩蓋13將線圈端部12a、12b與外部之間電性絕緣。此外,由於罩蓋13係利用熱傳導率比樹脂部14高之樹脂材料而形成,因此可將線圈12產生之熱有效率地排出。 Further, since the cover 13 is formed of a resin material having a higher electric resistance than the resin portion 14, the cover end 13 can electrically insulate the coil end portions 12a and 12b from the outside. Further, since the cover 13 is formed of a resin material having a higher thermal conductivity than the resin portion 14, the heat generated by the coil 12 can be efficiently discharged.

In the fifteenth diagram, the configuration in which the series of tapered portions 66e are formed along the axial direction of the central axis AX over the entire inner peripheral surface 66c is described as an example. However, the present invention is not limited thereto, and may be along the axial direction. A portion of the inner circumferential surface 66c is formed as a tapered portion 66e. The motor stator 60D shown in Fig. 16 uses a cover 66. In the motor stator 60D, the outer peripheral surface 14d of the resin portion 14 is formed along the tapered portion 66e. Therefore, the outer peripheral surface 14d of the resin portion 14 is formed so that the diameter becomes larger from the end surface 14a toward the end surface 14b. Thereby, it is possible to suppress the cover 66 from coming off in the axial direction of the central axis AX.
第17圖所示之罩蓋67係在內周面67c具有屬於縮徑部之段部67e。段部67e係將內周面67c中之端面67a側的直徑形成為比端面67b之直徑更小。在第17圖中,係列舉段部67e沿著中心軸AX之軸線方向形成為2段之構成為例加以說明,但並不限定於此,亦可形成為3段以上。第18圖所示之電動機定子60E係使用罩蓋67。在電動機定子60E中,樹脂部14之外周面14d係沿著段部67e而形成。因此,樹脂部14之外周面14d係形成為端面14b之直徑比端面14a側之直徑大。藉此,可抑制罩蓋67朝中心軸AX之軸線方向脫落。 The cover 67 shown in Fig. 17 has a section 67e belonging to the reduced diameter portion on the inner peripheral surface 67c. The segment portion 67e has a diameter smaller than the diameter of the end surface 67b in the end surface 67a side of the inner circumferential surface 67c. In the seventeenth diagram, the configuration in which the series of lifting portions 67e are formed in two stages along the axial direction of the central axis AX is described as an example. However, the present invention is not limited thereto, and may be formed in three or more stages. The motor stator 60E shown in Fig. 18 uses a cover 67. In the motor stator 60E, the outer peripheral surface 14d of the resin portion 14 is formed along the segment portion 67e. Therefore, the outer peripheral surface 14d of the resin portion 14 is formed such that the diameter of the end surface 14b is larger than the diameter of the end surface 14a side. Thereby, it is possible to suppress the cover 67 from coming off in the axial direction of the central axis AX.
第19圖所示之罩蓋68係在內周面68c具有絕緣層68e。絕緣層68e係使用絕緣帶或絕緣被膜。絕緣層68e係遍及內周面68c之整面而形成。此外,亦可為絕緣層68e形成在內周面68c之一部分的構成。第20圖所示之電動機定子60F係使用罩蓋68。在電動機定子60F中,係可在罩蓋68與線圈端部12a、12b之間容易地維持絕緣狀態。藉此,提升罩蓋68之安裝的作業性。 The cover 68 shown in Fig. 19 has an insulating layer 68e on the inner peripheral surface 68c. The insulating layer 68e is an insulating tape or an insulating film. The insulating layer 68e is formed over the entire surface of the inner peripheral surface 68c. Further, the insulating layer 68e may be formed in a part of the inner peripheral surface 68c. The motor stator 60F shown in Fig. 20 uses a cover 68. In the motor stator 60F, the insulating state can be easily maintained between the cover 68 and the coil end portions 12a, 12b. Thereby, the workability of the mounting of the cover 68 is improved.
實施形態7 Embodiment 7
第21圖係顯示實施形態7之電動機70之一例的圖。如第21圖所示,實施形態7之電動機70係具備:定子71;轉子72,係配置在定子71之內側;軸承74,係安裝在轉子72之軸(shaft)73;及托架(bracket)75,係壓入定子71。第21圖所示之定子71係列舉實施形態1所記載之電動機定子10,但並不限定於此,亦可使用實施形態2至實施形態6記載之任一種電動機定子。 Fig. 21 is a view showing an example of the motor 70 of the seventh embodiment. As shown in Fig. 21, the motor 70 of the seventh embodiment includes a stator 71, a rotor 72 disposed inside the stator 71, a bearing 74 mounted on a shaft 73 of the rotor 72, and a bracket (bracket). 75 is pressed into the stator 71. The stator 71 shown in FIG. 21 is the motor stator 10 described in the first embodiment. However, the present invention is not limited thereto, and any of the motor stators described in the second to sixth embodiments may be used.
實施形態7之電動機70係將定子71之線圈12產生之熱,從線圈端部12a、12b經由樹脂部14及罩蓋13傳達至托架75之底面部75a、75b及側面部75c而排出至外部。藉此,可將線圈12所產生之熱有效率地排出。 In the motor 70 of the seventh embodiment, the heat generated by the coil 12 of the stator 71 is transmitted from the coil end portions 12a and 12b to the bottom surface portions 75a and 75b and the side surface portion 75c of the bracket 75 via the resin portion 14 and the cover 13 to be discharged to external. Thereby, the heat generated by the coil 12 can be efficiently discharged.
以上實施形態所示之構成係顯示本發明之內容的一例者,亦可與其他之習知技術組合,在不脫離本發明之要旨的範圍內,亦可將構成之一部分予以省略、變更。 The configuration shown in the above embodiment is an example of the present invention, and may be combined with other conventional techniques, and a part of the configuration may be omitted or changed without departing from the gist of the present invention.
