Abstract
The invention relates to a stator lamination structure of a 4P electric motor and belongs to the technical field of electric motors. The stator lamination structure of the 4P electric motor comprises a lamination body, wherein 60-90 wire winding slots and multiple fastening slots are formed in the lamination body. Each wire winding slot comprises a first slot section at the outmost end, two sides of the first slot section are respectively connected with one oblique-line second slot section, the lower end of each second slot section is connected with an oblique-line third slot section, and the lower end of each third slot section is connected with a straight-sided fourth slot section. An included angle A formed by each third slot section and a horizontal line is 25-35 degrees, an included angle formed by each second slot section and a vertical center line of the corresponding wire winding slot is smaller than an included angle formed by each third slot section and a vertical center line of the corresponding wire winding slot. The stator lamination structure can meet the requirement for the motor efficiency, the production cost is reduced, and the problem of high cost of a YE2-280-4 motor is solved. Accordingly the market competitiveness of the motor is improved, and the stator lamination structure has good energy saving and emission reduction benefits.

The energy index of threephase asynchronous and the structure of its stator punching have very large contact, and the efficiency index that different structure (external diameter, central diameter and the flute profile that comprise stator punching) has different performances, especially motor has related to efficiency examination.Existing Y2 in the motor of YX3 series the structure of stator punching can not reach the energy efficiency indexes of stipulating in existing IEC standard.Therefore, the stator laminating structure of centering small machine redesigns and is inevitable.There is the too high problem of manufacturing cost in the stator punching of motor in the past, has had influence on the market competitiveness.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby a kind of stator laminating structure of 4P motor is provided, can, under the requirement that meets electric efficiency, reduce production costs.
According to technical scheme provided by the invention, the stator laminating structure of 4P motor comprises punching body, punching body center is provided with through hole, it is characterized in that: punching body is provided with 60～90 winding slots and a plurality of binding groove, winding slot is uniformly distributed along punching body inside edge, and a plurality of binding grooves are uniformly distributed along the external edge of punching; Winding slot comprises the first groove section that is positioned at outermost end, and the first Cao Duan both sides connect respectively the second groove section of an oblique line shape, and each the second Cao Duan lower end connects the three-flute section of an oblique line shape, and each three-flute section lower end connects the 4th groove section of a straightsided shape; Three-flute section and horizontal included angle A are 25
°～35
°, the angle of the second groove section and winding slot vertical center line is less than the angle of three-flute section and winding slot vertical center line.
Further, punching body diameter is 440 ~ 450mm, and punching body internal diameter is 300 ~ 315mm;
Further, binding groove is 9.
Further, winding slot is 72.
Further, the first groove section is semicircle, and the first Cao Duan place circular diameter is 7.5 ~ 10.2mm.
Further, the groove width of the second groove Duan Yu three-flute section junction is 5.5 ~ 7.8mm.
Further, the groove width at the 4th groove section place is 3.5～4.5mm.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable, can under the requirement that meets electric efficiency, reduce production costs, and has solved the problem of the high cost of YE2-280-4 motor; Thereby strengthened the market competitiveness of motor; There is good energy-saving and emission-reduction benefit.
