Claim 6:
7. A stator manufacturing method, comprising:
winding an elongated oriented silicon steel strip in the shape of a helix around a central axis and sequentially laminating and pressing the elongated oriented silicon steel strip into a ring shape to form a stator, wherein the stator comprises a stator yoke part and a plurality of stator tooth parts arranged at intervals along a circumferential direction, the stator yoke part is disposed along the circumferential direction of the stator tooth parts, and a grain direction of the formed oriented silicon steel strip points to a central axis of the stator along a radial direction; and the radial direction is a straight line direction along a radius of the stator, and the circumferential direction is a circumferential direction around a central axis of the stator.
