Stator, stator manufacturing method, motor, and electric vehicle

A motor, comprising a rotor and a stator, wherein the stator comprises:

• a stator tooth assembly including a plurality of stator tooth parts are arranged at intervals along a circumferential direction;
• and
• a stator yoke part disposed along a circumferential direction of the stator tooth assembly, wherein the circumferential direction is a circumferential direction around a central axis of the stator;
• wherein
• the stator tooth assembly and the stator yoke part together have a unitary construction formed from an oriented silicon steel strip wound in the shape of a helix around a central axis and sequentially laminated and pressed into a ring shape, wherein a grain direction of the formed oriented silicon steel strip points to the central axis of the stator along a radial direction, wherein the radial direction is a straight line direction along a radius of the stator;
• wherein the stator yoke part is disposed, along a circumferential direction of the stator tooth assembly, around an outer circumference of the stator tooth assembly or an inner circumference of the stator tooth assembly;
• and
• when the stator yoke part is disposed around the outer circumference of the stator tooth assembly, the stator is sleeved onto an outer circumference of the rotor;
• or
• when the stator yoke part is disposed around the inner circumference of the stator tooth assembly, the rotor is sleeved onto an outer circumference of the stator.
