現有馬達定子具有多個繞件及多個繞線組,每個所述繞件具有一纏繞槽,每個所述繞線組以集中繞線方式纏繞滿所述纏繞槽。然而,現有馬達定子的所述繞線組大多採用漆包線,也就是說,每個所述繞線組的橫斷面為圓形,因此儘管每個所述繞線組纏繞滿所述繞件的所述纏繞槽,但每個相鄰的漆包線之間會存在有間隙,也就是說於所述纏繞槽內的所述繞線組受限於形狀而產生間隙的堆積效應,導致所述纏繞槽內仍有許多空間無法被填滿。The existing motor stator has a plurality of winding elements and a plurality of winding groups, each of the winding elements has a winding groove, and each of the winding groups is wound around the winding groove in a concentrated winding manner. However, enameled wires are mostly used for the windings of the existing motor stators, that is to say, the cross section of each winding is circular, so although each winding is fully wound around the winding element The winding groove, but there will be a gap between each adjacent enameled wire, that is to say, the winding group in the winding groove is limited by the shape to produce a stacking effect of gaps, resulting in the winding groove. There is still a lot of space inside that cannot be filled.
然而,當採用具有線徑較粗(較大截面積)的漆包線進行纏繞時,漆包線會難以彎折並纏繞於對應的所述繞件上,導致現有馬達定子於製作上仍有需要改善的缺點。However, when an enameled wire with a thicker wire diameter (larger cross-sectional area) is used for winding, the enameled wire is difficult to bend and wind on the corresponding windings, resulting in the disadvantage that the existing motor stator still needs to be improved in manufacturing. .
