The invention discloses a motor stator groove opening structure. A motor stator includes a stator winding and a stator iron core. The stator winding is composed of multiple copper wires. The stator iron core is provided with multiple stator grooves. The copper wires are placed in the stator grooves. The stator grooves are of a rectangular structure. The stator core at one end of each stator grooveis expanded from the outside to the inside to form a structure with outside and narrow inside. The end openings of the stator grooves are made large by the expansion of the stator core at the ends ofthe stator grooves, which facilitates the insertion of insulation paper and the copper wires, can avoid the damage of the copper wires during twisting, and can reduce the height of the ends. 本发明公开了一种电机定子槽口结构，所述电机定子包括定子绕组和定子铁芯，所述定子绕组由多根铜线构成，所述定子铁芯上设置多个定子槽，所述铜线置于所述定子槽内，所述定子槽为矩形结构，所述定子槽一端处定子铁芯由外向内冲扩成外宽内窄结构，通过对所述定子槽端部定子铁芯的冲扩使得所述定子槽端口较大，不仅方便绝缘纸、铜线的插入，而且能够避免铜线在扭线过程中损伤，同时也能够降低端部高度。
