It should be noted that the protrusion 3 may also be divided into 3 or more than 3 parts, and the bottom section plays a guiding role. The present embodiment takes the case that the projection 3 is divided into 2 parts.
In the utility model, the stator is formed by winding the silicon steel sheet 1, and the stator slot 2 is formed by punching the slot on the silicon steel sheet 1. Because the silicon steel sheet 1 goes up the punching and is equipped with arch 3, and arch 3's the back forms the recess, and arch 3 on the same layer can be pegged graft with the recess of adjacent layer, consequently, when the stator coiling shaping, can avoid the stator to appear the problem of layering when receiving inhomogeneous axial force through the joint of arch 3 and recess is spacing. The probability of the stator delaminating when subjected to non-uniform axial forces is reduced.
In addition, the protrusion 3 comprises a first protrusion and a second protrusion which are coaxially arranged, and the diameter of the second protrusion gradually decreases along the direction away from the axial lead of the stator, namely, the second protrusion provides a guiding function for the protrusion 3, so that the insertion fit between the protrusion 3 and the groove is facilitated.
