Abstract:
Disclosed are a stator and a fan. The stator comprises: an annular stator outer ring. A plurality of stator teeth which are uniformly distributed are connected in the circumferential direction of the inner side of the stator outer ring; the stator teeth are provided along the radial direction of the stator outer ring; a winding group coil is wound outside each stator tooth, the depths of first lead grooves of the insulating wire frames corresponding to the winding group coils in the same phase are the same, and the depths of the first lead grooves of the insulating wire frames corresponding to the winding group coils in different phases are different from each other, so that in the circumferential direction of the outer portion of the stator outer ring, the wires of different phases are staggered in height, and thus the wires of the phases of the stator are arranged in order.
