請參照第1圖,定子結構100包含一鐵芯組件110。鐵芯組件110包含一環狀部112以及複數個齒部114,該些個齒部114自環狀部112沿徑向朝鐵芯組件110之環心110c內延伸。每一個齒部114的周圍套設絕緣的繞線架116,使線圈導線繞線時能更佳絕緣於鐵芯組件110。定子結構100包含複數個由扁平導線組成的線圈組件120,每一個線圈組件120配置於對應的一齒部114上。製程上,使用扁平導線組成的線圈組件120將其套上齒部114能較快速徑向地堆疊繞線於每一齒部114上,減少繞線耗費的工時。扁平導線組成的線圈組件120亦有助於提升車用馬達定子的運轉功率。Referring to FIG. 1 , the
請參照第2圖,每一個線圈組件包含一第一扁平導線122以及複數個電性並連的第二扁平導線124。第一扁平導線122由齒部114的根部114c徑向地堆疊繞線於齒部114上。該些個第二扁平導線124徑向相鄰於第一扁平導線122且電性串連至第一扁平導線122。在本發明的一實施例中,每一個線圈組件包含一第一扁平導線122以及兩個電性並連的第二扁平導線124,且兩個電性並連的第二扁平導線(1241、1242)徑向交替地堆疊繞線於齒部114(請同時參照第3圖,兩個第二扁平導線1241、1242以不同灰階填色區分)。在本發明的其他實例中,每一個線圈組件可包含三個或更多電性並連的第二扁平導線。該些個第二扁平導線124之堆疊繞線相較第一扁平導線122之堆疊繞線遠離環狀部112。上述第一、二扁平導線122、124的電性配置有助於減低定子結構運作時功率耗損。由於第一、二扁平導線122、124具有相等的導體截面積,而利用不同的導線截面尺寸可以進一步增加導體的槽滿率,能有效降低直流的銅線損耗。另外,第一扁平導線122串聯第二扁平導線124,再將第二扁平導線124分割成1241、1242可以減少靠近齒部的頭部114b的銅線每一個單一導體的截面積,藉以在磁場密度高的地方降低單一導體截面積,可以有效降低交流的銅線損耗。Please refer to FIG. 2 , each coil assembly includes a first

在本發明的一實施例中,每一該些個第二扁平導線124單根的截面徑向厚度相互加總(即導線1241截面徑向厚度T2a+導線1242截面徑向厚度T2b)大於第一扁平導線122單根的截面徑向厚度(T1),且所有堆疊繞線於齒部114的該些個第二扁平導線124的截面徑向厚度的加總(沿徑向R的T2sum)小於所有堆疊繞線於齒部114的第一扁平導線122的截面徑向厚度的加總(沿徑向R的T1sum),藉以將導線佔槽的比率增加。In an embodiment of the present invention, the sum of the cross-sectional radial thicknesses of each of the second flat wires 124 (that is, the cross-sectional radial thickness T2a of the
在本發明的一實施例中,一齒部114的截面寬度W3(垂直徑向R的厚度)從其根部114c至頭部114b是均勻相等的。在本發明的一實施例中,齒部114包含一側表面114a於齒部的根部114c垂直連接或接近垂直連接環狀部112的內環面112a,藉以配置近似矩形截面的第一扁平導線122與第二扁平導線124。在本發明的一實施例中,該些個第二扁平導線124單根截面積是相互相等或接近相等的(例如第二扁平導線1241、1242單根截面積相互相等或接近相等的),藉以維持每個第二扁平導線124電流密度大致相等。在本發明的其他實施例中,該些個第二扁平導線單根截面積是相互不相等的,例如第二扁平導線1241、1242單根截面積之間相互有整數或接近整數的比例關係。In an embodiment of the present invention, the cross-sectional width W3 (thickness perpendicular to the radial direction R) of a
請參照第4圖,鐵芯組件110具有彼此相對的第一側110a與第二側110b。第一扁平導線122的第一端122a與該些個第二扁平導線124的第一端124a分別突出於鐵芯組件110的第一側110a。第一扁平導線122的第二端122b與該些個第二扁平導線124的第二端124b彼此連接形成之接合部位於鐵芯組件110的第二側110b,利於第一扁平導線122的第二端122b與該些個第二扁平導線124的第二端124b彼此連接(例如藉焊接方式形成接合部)。上述扁平導線的第一端(122a、124a)與第二端(122b、124b)分別配置於鐵芯組件110的二相對側,亦有助於定子結構之繞組電極的配置。例如,第一扁平導線的第一端122a用以連接電相端,第二扁平導線的第一端124a用以連接電性中性端;或者第一扁平導線的第一端122a用以連接電性中性端,第二扁平導線的第一端124a用以連接電相端。Referring to FIG. 4 , the

The two types of flat wires include a first flat wire electrically connected in series to a plurality of second flat wires electrically connected in parallel. The second flat wires are radially adjacently stacked on the first flat wires, and alternately stacked and wound on the tooth portion in the radial direction. The sum of the cross-sectional radial thicknesses of each of the second flat wires is greater than the cross-sectional radial thickness of the first flat wires, and the cross-sectional radial thickness of all the second flat wires stacked and wound on the tooth portion The sum is smaller than the sum of the cross-sectional radial thicknesses of all the stacked first flat wires wound around the teeth. With the configuration of the above two flat wires, the ratio of the wires to the slots can be better improved, the stator operation loss can be reduced, and the operation performance of the stator structure of the vehicle motor can be improved.
