Abstract
The utility model discloses a kind of type stator lamination, include the stator core body of coiling and molding, the yoke portion of described stator core body is provided with the hollow-out parts adjusting the portion's deformation of stator core yoke.When rushing band and entering winding deformation space, due to the existence of hollow-out parts, the deformation in yoke portion is adjusted by hollow-out parts, and the deformation in hollow-out parts space has liquidated the deformation in yoke portion, and now, yoke portion can not produce gauffer again, improves the quality of stator core.
Description
Technical field
The utility model relates to a kind of type stator lamination.
Background technology
At present, in the mode of production of type stator iron core, wherein there is the process stamping forming billot being wound into helical form stator lasmination, only space constraint is adopted to billot in this process, in winding process, back-moving spring imposes monolateral axial force to driving-disc, force the monolateral in the axial direction carrying of driving-disc, produce unbalance loading during rotation to swing, the irregular change of the generating period thereupon of the band curling and deformation space between limiting plate and driving-disc end face, the yoke portion rushing band is caused to occur harmful deformation defect---fold, its rule is: the yoke of motor stator core is wide larger, fold is more serious, the yoke portion deformation curvature of motor stator core is larger, and fold is more serious.
Utility model content
The purpose of this utility model is to provide a kind of type stator lamination, can avoid the gauffer that the yoke portion deformation because of stator core produces, and then improve the quality of stator core.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of type stator lamination, includes the stator core body of coiling and molding, it is characterized in that: the yoke portion of described stator core body is provided with to adjust the hollow-out parts of stator core yoke portion's deformation.
There is more than 1 or 1 hollow-out parts in the yoke portion that on described stator core body, each teeth are corresponding.
Described hollow-out parts is rectangle, strip.
Adopt the type stator lamination of said structure, the yoke portion of stator core body is provided with hollow-out parts, when rushing band and entering winding deformation space, due to the existence of hollow-out parts, the deformation in yoke portion is adjusted by hollow-out parts, and the deformation in hollow-out parts space has liquidated the deformation in yoke portion, now, yoke portion can not produce gauffer again, improves the quality of stator core.
Accompanying drawing explanation
Fig. 1 is the partial schematic diagram that in prior art, stator core exists gauffer;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is A indication position enlarged drawing in Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, in prior art yoke wide larger when, type stator iron core body punching band through winding deformation space after, the yoke portion deformation produced i.e. gauffer, reduce product quality.
As Figure 2-3, a kind of type stator lamination, includes the stator core body 1 of coiling and molding, and the yoke portion of described stator core body 1 is provided with the hollow-out parts 11 adjusting the portion's deformation of stator core yoke.There is more than 1 or 1 hollow-out parts in yoke portion corresponding to each teeth on described stator core body.Described hollow-out parts 11 is rectangle, strip.
Adopt the type stator lamination of said structure, the yoke portion of stator core body 1 is provided with hollow-out parts 11, when rushing band and entering winding deformation space, due to the existence of hollow-out parts 11, the deformation in yoke portion is adjusted by hollow-out parts, and the deformation in hollow-out parts space has liquidated the deformation in yoke portion, now, yoke portion can not produce gauffer again, improves the quality of stator core.
Claims (3)
