Motor stator punching sheet

The utility model discloses a motor stator punching sheet. Wherein a central hole is formed in the middle of the punching sheet; 36 wire embedding grooves are formed in the inner side of the punchingsheet; the wire embedding groove is a flat bottom groove; the diameter D1 of the tangent circle of the groove bottom of the wire embedding groove ranges from 113.6 mm to 117.6 mm. The range of the groove area S of a single wire embedding groove is 59.4 mm < 2 > to 63.4 mm < 2 >; the outer diameter D2 of the punching sheet ranges from 138 mm to 142 mm; the inner diameter D3 of the center hole ranges from 86 mm to 92 mm. A plurality of cutting edges are arranged on the outer edge of the punching sheet along the circumferential direction; the distance L1 between the two cut edges symmetrical about the central axis ranges from 136 mm to 140 mm, and the wire embedding groove is changed into the flat-bottom wire embedding groove, so that the diameter of the groove bottom of the wire embedding groove and the area of a si
