The stator of the slot. The stator system has: the first insulator, which is set at one end of the stator along the central axis of the core back; the second insulator, which is set at the other end of the stator along the central axis; the coil wire, which is adjacent every two teeth are wound consecutively; and a conductive terminal is fixed to the first insulator to hold the coil wire. The coil wire system includes a jumper wire extending from one of two adjacent teeth to the other. A cavity into which the terminal is inserted is formed in the first insulator. A jumper is arranged in the second insulating material system.

依據本揭露，達到即使線圈線連續纏繞至相鄰的齒且在絕緣件設有凹穴時，仍能夠抑制電動機的沿中心軸的尺寸增加的功效。 According to the present disclosure, even when the coil wire is continuously wound to the adjacent teeth and the insulator is provided with the recess, the effect of suppressing the increase in the size of the motor along the central axis is achieved.

As shown in FIGS. 4 and 5 , a first slit 93 for holding the coil wire 7 and a second slit 94 for holding the lead wire 8 are formed in the connection terminal 9 . The first slit 93 and the second slit 94 extend from one side wall 91 to the other side wall 91 through the bottom wall 92 . When the connection terminal 9 is inserted into the first cavity 61a, the first slit 93 communicates with the second cavity 61b, and the second slit 94 communicates with the third cavity 61c.

如圖5所示，線圈線7乃係導電性的芯線71以絕緣覆層72包覆而成的絕緣導體。另外，在圖5中係為了說明上的方便而以虛線來圖示絕緣覆層72。芯線71係例如為銅線等。在線圈線7係從未圖示的變頻器(inverter)經由引線8獲得電力供給。針對線圈線7係於後文詳細說明。 As shown in FIG. 5 , the coil wire 7 is an insulated conductor in which a conductive core wire 71 is covered with an insulating coating 72 . In addition, in FIG. 5, the insulating coating layer 72 is shown by the dotted line for convenience of description. The core wire 71 is, for example, a copper wire or the like. Electric power is supplied to the coil wire 7 via a lead wire 8 from an inverter (not shown). The details of the coil wire 7 will be described later.

引線8乃係具有複數條導線81的導電性的絞線以絕緣覆層82總括包覆而成的絕緣導體。另外，在圖5中係為了說明上的方便而以虛線來圖示絕緣覆層82。導線81係例如為銅線等。引線8係將未圖示的變頻器與電動機100連接。引線8乃係供從未圖示的變頻器供給電力至各線圈之用的導體。 The lead wire 8 is an insulated conductor composed of a plurality of conductive strands 81 covered with an insulating coating 82 . In addition, in FIG. 5, the insulating coating layer 82 is shown by the dotted line for convenience of description. The wire 81 is, for example, a copper wire or the like. The lead wire 8 connects the inverter (not shown) and the motor 100 . The lead wire 8 is a conductor for supplying electric power to each coil from an inverter not shown in the figure.

第1狹縫93的寬度係形成為比線圈線7中以絕緣覆層72包覆的部位的外徑還小。因此，在將接線端子9***至第1凹穴61a內時，以第1狹縫93的內壁削掉線圈線7的絕緣覆層72，從而芯線71露出。藉此，線圈線7的芯線71與接線端子9接觸，從而線圈線7與接線端子9接通。線圈線7中只有保持在第1狹縫93內的部位被剝除絕緣覆層72，從而芯線71接通至接線端子9。線圈線7中只有保持在第1狹縫93內的部位係以被剝除掉絕緣覆層72的狀態使芯線71壓接於第1狹縫93的內壁。線圈線7中保持在第1狹縫93內的部位以外的部位係保留有絕緣覆層72。 The width of the first slit 93 is formed to be smaller than the outer diameter of the portion of the coil wire 7 covered with the insulating coating 72 . Therefore, when the connecting terminal 9 is inserted into the first cavity 61a, the insulating coating 72 of the coil wire 7 is scraped off by the inner wall of the first slit 93, and the core wire 71 is exposed. As a result, the core wire 71 of the coil wire 7 comes into contact with the connection terminal 9 , so that the coil wire 7 and the connection terminal 9 are connected. Only the part of the coil wire 7 held in the first slit 93 is stripped of the insulating coating 72 , so that the core wire 71 is connected to the connection terminal 9 . Only the portion of the coil wire 7 held in the first slit 93 is crimped to the inner wall of the first slit 93 with the core wire 71 in a state where the insulating coating 72 is stripped off. The insulating coating 72 remains on the coil wire 7 other than the portion held in the first slit 93 .

Therefore, when the connecting terminal 9 is inserted into the first cavity 61a, the insulating coating 82 of the lead wire 8 is chipped off by the inner wall of the second slit 94, and the lead wire 81 is exposed. As a result, the conductive wire 81 of the lead wire 8 comes into contact with the connection terminal 9 , so that the lead wire 8 and the connection terminal 9 are connected. Only the portion of the lead wire 8 held in the second slit 94 is stripped of the insulating coating 82 so that the lead wire 81 is connected to the connection terminal 9 . Only the portion of the lead wire 8 held in the second slit 94 is crimped to the inner wall of the second slit 94 by crimping the stranded wire having a plurality of conducting wires 81 in a state where the insulating coating 82 is stripped off. The insulating coating 82 remains on the lead wire 8 other than the portion held in the second slit 94 .

在繞線步驟中，首先，於齒4a纏繞第一層的線圈線7。將第一層的線圈線7於齒4a的長邊部42a從接線側朝反接線側纏繞。在於第一層的第一列纏繞線圈線7時，線圈線7係因導引部11而往徑方向內側偏 移。藉由線圈線7往徑方向內側偏移，線圈線7在短邊部43b係傾斜纏繞，而在長邊部42a、長邊部42b及短邊部43a係形成對齊纏繞。自第二列起的線圈線7係以已經纏繞好的線圈線7作為導引部而依序纏繞。此外，雖省略圖示，但自第二層起的線圈線7也依序纏繞至已經纏繞好的線圈線7之上。在最終匝係如圖13及圖14中所示的元件符號a所示，令線圈線7於齒4a的長邊部42a從接線側前往反接線側，並且如圖14中所示的元件符號a、b所示，一邊使線圈線7沿徑方向移動一邊進行升層。 In the winding step, first, the coil wire 7 of the first layer is wound around the teeth 4a. The coil wire 7 of the 1st layer is wound around the long side part 42a of the tooth 4a from the connection side to the reverse connection side. When the coil wire 7 is wound on the first row of the first layer, the coil wire 7 is deflected radially inwardly due to the guide part 11 shift. As the coil wire 7 is shifted inward in the radial direction, the coil wire 7 is wound obliquely at the short side 43b, and is aligned and wound at the long side 42a, the long side 42b, and the short side 43a. The coil wires 7 from the second row are sequentially wound with the already wound coil wire 7 as a guide. In addition, although illustration is omitted, the coil wire 7 from the second layer is also wound sequentially on the already wound coil wire 7 . In the final turn system as shown in Figure 13 and the element symbol a shown in Figure 14, let the coil wire 7 go from the connection side to the reverse connection side on the long side part 42a of the tooth 4a, and the element symbol shown in Figure 14 As shown in a and b, the layer is raised while moving the coil wire 7 in the radial direction.

接著，如圖14所示，在反接線側將線圈線7從齒4a的長邊部42a跨往齒4b的長邊部42c。亦即，從長邊部42a往長邊部42c拉出跨線75。接著，如圖13及圖14所示，於齒4b纏繞第一層的線圈線7。將第一層的線圈線7於齒4b的長邊部42c從反接線側朝接線側纏繞。於第一層的第一列纏繞線圈線7時，纏繞至短邊部43d的線圈線7係因已經纏繞在長邊部42c的線圈線7而往徑方向內側偏移，而纏繞至長邊部42c、長邊部42d及短邊部43c的線圈線7係形成對齊纏繞。自第二列起的線圈線7係以已經纏繞好的線圈線7作為導引部而依序纏繞。此外，雖省略圖示，但自第二層起的線圈線7也依序纏繞至已經纏繞好的線圈線7之上。在最終匝係如圖13及圖14中所示的元件符號d所示，令線圈線7於齒4b的長邊部42c從反接線側前往接線側，並且如圖14中所示的元件符號c、d所示，一邊使線圈線7沿徑方向移動一邊進行升層。藉由上述，使線圈線7連續纏繞至相鄰的兩個齒4a、4b。 Next, as shown in FIG. 14 , the coil wire 7 is passed from the long side portion 42 a of the tooth 4 a to the long side portion 42 c of the tooth 4 b on the reverse wiring side. That is, the jumper 75 is pulled out from the long side portion 42a toward the long side portion 42c. Next, as shown in FIGS. 13 and 14 , the coil wire 7 of the first layer is wound around the teeth 4 b. The coil wire 7 of the 1st layer is wound around the long side part 42c of the tooth 4b from the reverse connection side toward the connection side. When the coil wire 7 is wound in the first row of the first layer, the coil wire 7 wound to the short side 43d is shifted inward in the radial direction due to the coil wire 7 wound on the long side 42c, and wound to the long side The coil wire 7 of the portion 42c, the long side portion 42d, and the short side portion 43c is wound in alignment. The coil wires 7 from the second row are sequentially wound with the already wound coil wire 7 as a guide. In addition, although illustration is omitted, the coil wire 7 from the second layer is also wound sequentially on the already wound coil wire 7 . In the final turn system as shown in Figure 13 and the element symbol d shown in Figure 14, let the coil wire 7 go from the reverse wiring side to the wiring side on the long side part 42c of the tooth 4b, and the element symbol shown in Figure 14 As shown in c and d, the layer is raised while moving the coil wire 7 in the radial direction. By doing so, the coil wire 7 is continuously wound around two adjacent teeth 4a, 4b.

在本實施型態中，在短邊部43a、43c中線圈線7係形成對齊纏繞，故當將全部的第2升層部77配置在定子1的沿中心軸C的單側 時、亦即將全部的第2升層部77配置在短邊部43a、43c時，線圈線7纏繞至齒4的纏繞變得容易。因此，能夠簡化將線圈線7纏繞至齒4的製造裝置。 In this embodiment, the coil wires 7 are aligned and wound in the short side portions 43a, 43c, so when all the second lifting portions 77 are arranged on one side of the stator 1 along the central axis C In other words, when all the second step-up portions 77 are disposed on the short side portions 43a and 43c, the winding of the coil wire 7 around the teeth 4 becomes easy. Therefore, the manufacturing device for winding the coil wire 7 to the tooth 4 can be simplified.
