Wound type motor stator structure

The utility model relates to a winding formation structure of a motor stator which comprises a winding formation punching sheet, wherein the yoke part of the stator punching sheet and the upper part of each wire chase are respectively provided with a cambered process cut, and the bending directions of the process cuts are repeatedly arranged according to recycle units. The utility model can assure the bending directions of the process cuts which are opposite to one another between an upper layer and a lower layer to be overlapped in an alternating way; thus, magnetic leakage is reduced, the magnetic permeability and the mechanical strength of the stator are enhanced, therefore the integral performance of the motor is enhanced. The utility model is especially suitable for the motor stators with major diameters, small unfold angles and asymmetric shapes of pole teeth.
