The utility model provides a stator punching sheet, a stator core, a motor and a compressor, and the stator punching sheet comprises a yoke part which is provided with an inner hole; the plurality of stator tooth parts are distributed at intervals along the circumferential direction of the inner hole; the plurality of cut edges are distributed at intervals along the peripheral surface of the yoke part and extend along the axial direction of the yoke part; the cutting grooves are formed in the cutting edges, the cutting grooves extend in the axial direction of the yoke part, and the multiple cutting grooves and the multiple cutting edges are arranged in a one-to-one correspondence mode. By adopting the scheme, the plurality of cutting edges are distributed at intervals along the peripheral surface of the yoke part, and the plurality of cutting grooves and the plurality of cutting edges are arranged in one-to-one correspondence, so that the raw material consumption cost of the stator punching sheet can be reduc
