Embodiment Construction

[0015] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0016] Such as figure 1 , figure 2 As shown, it includes the stator punching body 1, the buckle slot 2, the stator punching slot 3, the semicircular part 3-1, the side 3-2, the hypotenuse 3-3, the straight side 3-4, etc.

[0017] Such as figure 1 , figure 2 As shown, the present invention is a stator stamping structure of an electric motor, including an annular stator stamping body 1, the inner diameter a of the stator stamping body 1 is 260-265mm, and the outer diameter b is 440-450mm. Among them, the inner diameter of the stator punch body 1 is preferably 262mm, and the outer diameter is preferably 445mm; 9 buckle slots 2 are evenly distributed on the outer circumference of the stator punch body 1, and 36 to 60 stator slots are evenly distributed on the inner circumference. The number of stamping grooves 3 and stator stamping bodies 1 is preferably 48. ...

Abstract

The invention belongs to the technical field of motors and relates to a stator punching sheet structure of a motor, in particular to a stator core suitable for a medium-and-small-sized motor. The stator punching sheet structure comprises a circular stator punching sheet body and is characterized in that an inner diameter a of the stator punching sheet body is 260-265 mm, an outer diameter b of the stator punching sheet body is 440-450 mm, nine sheet buckling grooves are uniformly formed in the outer circumferential surface of the stator punching sheet body, and 36-60 of stator punching sheet grooves are uniformly formed in the inner circumferential surface of the stator punching sheet body. With the adoption of the stator punching sheet structure, the problem that the cost of a YE2-280-2 motor is too high is solved, so that market competitiveness of the motor is enhanced and better energy conservation and emission reduction benefits are provided.

Description

technical field [0001] The invention belongs to the technical field of electric motors, and relates to a stator punching structure of electric motors, in particular, it is especially suitable for stator iron cores of small and medium-sized electric motors. Background technique [0002] The force index of the three-phase asynchronous motor has a great relationship with the structure of the stator punch. Different structures (including the outer diameter, middle diameter and groove shape of the stator punch) will have different performances, especially the efficiency index of the motor. Involved in energy efficiency assessment. The structure of stator stamping in the existing Y2\YX3 series motors can no longer meet the energy efficiency index stipulated in the current IEC standard. Therefore, it is inevitable to redesign the stator punching structure of small and medium motors. The previous design only paid attention to the change of the groove shape, but did not give much c...
