The structure of the annular integral stator punching sheet stacked into the stator core is such that several winding grooves are punched on the annular sheet material. This integral stator structure design has the following defects: due to the influence of the winding groove structure, there is a certain process difficulty when entering the winding into the winding groove, the winding step is difficult, and the design of the stator and the winding groove structure is more difficult during the winding process. It is necessary to wind each winding separately and then weld it, which increases the process steps, increases the labor cost, and seriously affects the production efficiency.
