    • A method of manufacturing a stator includes the steps of: (1) forming substantially planar electric wires each of which includes in-slot portions to be received in slots of a stator core and turn portions to be located outside the slots to connect adjacent pairs of the in-slot portions; (2) rolling each of the planar electric wires by more than one turn into a spiral shape; (3) forming a stator coil by assembling the rolled electric wires through elastic deformation thereof; and (4) assembling the stator core and the stator coil to form the stator. Further, in the rolling step, each of the planar electric wires is rolled by plastically deforming the turn portions into circumferentially-extending sections each having a predetermined curvature. Furthermore, a curvature ratio of a radially outermost one of the circumferentially-extending sections is set to be greater than that of a radially innermost one of the same.
    • 一种制造定子的方法包括以下步骤:(1)形成基本上平面的电线,每个电线包括被接纳在定子铁芯的槽中的槽内部分,并且转动部分位于槽的外侧,以连接相邻的一对 槽内部分; (2)将各个平面电线卷绕成多于一圈的螺旋形状; (3)通过弹性变形组装轧制的电线来形成定子线圈; 和(4)组装定子铁芯和定子线圈以形成定子。 此外,在轧制步骤中,每个平面电线通过将转弯部分塑性变形成各自具有预定曲率的周向延伸部分而卷起。 此外,周向延伸部的径向最外侧的曲率比设定为大于其径向最内侧的曲率比。
