Winding end structure, stator assembly and winding processing method

A winding end structure is arranged at one end of a motor stator and comprises a plurality of wires distributed in multiple layers in the circumferential direction of the motor stator, the wires in the adjacent layers intersect with each other, and the wires are connected through welding areas. Wherein a radial gap in the radial direction of the motor stator is formed between the crossed position, closest to the welding area, of each wire and the crossed wire, so that insulating sections between the wires are not in contact with each other. The winding end part structure effectively improves the insulation performance of the end part of the motor stator, and improves the operation stability of the motor. 一种绕组端部结构，设置在电机定子的一端，包括多条绕电机定子周向成多层分布的导线，相邻层中的导线相互交叉，导线之间通过焊接区相连，其中每条导线距离焊接区最近的交叉位置与相交叉的导线之间存在沿电机定子径向的径向间隙，使导线间的绝缘段互不接触。该绕组端部结构有效提高了电机定子端部的绝缘性能，改善了电机运行的稳定性。
