    • A stator winding of an electric rotating machine comprising a plurality of in-slot conductors arranged, respectively, in a plurality of slots, and a plurality of coil end conductors for continuously interconnecting the in-slot conductors arranged in different slots at the outside of the end face of a stator core. The plurality of in-slot conductors are arranged in each slot in one row in the depth direction. A coil end part has a root portion led out from the slot opening in the end face of the stator core in the extending direction of the in-slot conductors in the slot, and a connecting portion bent to bridge two root parts. In each slot opening, root parts are arranged in the depth direction of the slot in a row to form a root part row, and cooling passages are formed on both sides of each root part row to extend in the depth direction of the slot along one end face. The connecting parts are overlapped with each other at the outside of each root part row to form an end tubular section, and an insulating member is provided to the end tubular section to cover at least the outer surface of the end tubular section.
    • 一种旋转电机的定子绕组,包括分别布置在多个槽中的多个内槽导体和多个线圈端导体,用于连续地互连布置在不同槽中的槽内导体 定子铁芯的端面。 多个槽内导体沿深度方向布置在每个槽中的一行中。 线圈端部具有从狭槽中的槽内导体的延伸方向上从定子铁心的端面中的槽口引出的根部,以及弯曲成桥接两个根部的连接部。 在每个槽口中,根部沿着槽的深度方向排列成一根根部排,并且在每个根部排的两侧形成冷却通道,沿着槽的深度方向沿着一个 端面。 连接部分在每个根部排的外侧彼此重叠以形成端部管状部分,并且绝缘部件设置在端部管状部分上以至少覆盖端部管状部分的外表面。
