    • The present invention provides a dynamoelectric stator and a method for the manufacture thereof enabling electrical insulation properties to be improved by forming slot-housed portions with a racetrack-shaped cross section to suppress damage to an electrically-insulating coating arising during mounting of a stator winding to a stator core. The construction is such that the slot-housed portions of the stator winding are formed with the racetrack-shaped cross section, and are housed inside slots so as to line up in single columns in a radial direction with a longitudinal direction of the cross section of the slot-housed portions aligned in a circumferential direction. Thus, because short sides of the slot-housed portions facing inner circumferential side surfaces of the slots form convex curved surfaces, the occurrence of damage to the electrically-insulating coating resulting from rubbing between the short sides of the slot-housed portions and the inner circumferential side surfaces of the slots during insertion of the slot-housed portions into the slots is suppressed, thereby improving electrical insulation properties.
    • 本发明提供一种电动定子及其制造方法,其能够通过形成具有跑道形横截面的狭槽收纳部分来改善电绝缘性能,以抑制在定子绕组安装期间产生的电绝缘涂层的损坏 到定子铁心。 该结构使得定子绕组的狭槽容纳部分形成有跑道形横截面,并且容纳在狭槽内,以沿径向方向排列成单列,其横截面的纵向方向 狭槽收纳部沿圆周方向排列。 因此,由于槽狭槽容纳部的面向槽的内周侧面的短边形成凸曲面,所以由于在狭槽收容部的短边与内侧的内侧之间的摩擦而导致的电绝缘涂层的损伤的发生 抑制了将槽容纳部分插入槽内的槽的圆周侧表面,从而提高了电绝缘性能。
