Abstract
The utility model relates to a stator punching sheet structure of a 4P motor and belongs to the technical field of motors. The stator punching sheet structure comprises a punching sheet body which is provided with 60-90 wire winding grooves and a plurality of fastening grooves. Each wire winding groove comprises a first groove section positioned on the outermost end. Two sides of the first groove section are respectively connected with a second groove section shaped as an oblique line. The lower end of each second groove section is connected with a third groove section shaped as an oblique line. The lower end of each third groove section is connected with a fourth straight-sided groove section. The included angle between the third groove section and the horizontal line is an included angle A which ranges from 25 degrees to 35 degrees. The included angle between the second groove section and a vertical center line of the wire winding groove is less than the included angle between the third groove section and the vertical center line of the wire winding groove. According to the utility model, motor efficiency requirements can be met; production cost is reduced; and the problem that cost of a YE2-280-4 motor is high is solved. Thus, motor market competitiveness is raised. The stator punching sheet structure has good benefits in energy saving and emission reduction.
