Claim 9:
10. 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.
