Abstract: Embodiments of this application disclose a stator, a stator manufacturing method, a motor, and an electric vehicle. The stator includes: a stator tooth part, where a plurality of stator tooth parts are arranged at intervals along a circumferential direction; and a stator yoke part, where the stator yoke part is disposed along a circumferential direction of the stator tooth part, and the circumferential direction is a circumferential direction around a central axis of the stator; where the stator tooth part and the stator yoke part are integrally formed by an oriented silicon steel sheet, and a grain direction of the formed oriented silicon steel sheet points to the central axis of the stator along a radial direction. Therefore, the stator tooth part and the stator yoke part are formed by using one material, and there is no need to splice two materials, thereby reducing process costs.
