Structure for enhancing rigidity of end teeth of stator core

The utility model relates to a structure for enhancing the rigidity of end teeth of a stator core. The structure comprises at least two symmetrical punching sheet teeth and small groove structures, wherein the small groove structure formed on the punching sheet tooth on the left side of the symmetrical line is positioned on the left side of the central line of the teeth section; and the small groove structure formed on the punching sheet tooth on the right side of the symmetrical line is positioned on the right side of the central line of the teeth section. Due to the design that the small structure is deflected from the center of the teeth, the small grooves on the stacked punching sheets are dislocated, thereby enhancing the rigidity of the teeth section of the iron core. Accordingly, the alternate axial force is applied on the entire teeth section instead of half of the teeth section, thereby obviating broken teeth due to fatigue of the teeth section and ensuring safe operation of the stator core.
