Accompanying drawing explanation
Fig. 1 is the structural representation of the stator core of the ventilated machine of the utility model one embodiment.
Wherein, description of reference numerals is as follows:
10, stator core; 1, the first punching sheet unit; 2, the second punching sheet unit; 3, the 3rd punching sheet unit; 4, the 4th punching sheet unit.
Embodiment
Below with reference to accompanying drawing, elaboration is further given to the utility model.
A kind of ventilated machine that the utility model provides, it comprises a stator core, wherein, stator core is laminated by the punching sheet unit segmentation that at least two overall dimension is different and is formed, make the periphery concave-convex surface of stator core, and directly contact with air, add the area of dissipation of ventilated machine, to improve the radiating effect of ventilated machine.Wherein, punching sheet unit is again laminated by the stator punching segmentation that multiple overall dimension is identical to be formed, and stator punching is silicon steel sheet.By this stator core in irregular shape of the transverse direction in alternative conventional motors profile or longitudinal rib sheet, by the heat of ventilated machine inside (such as, the heat produced during the work of motor winding, stator core) be directly passed to the outside of ventilated machine, namely the ventilated machine that the utility model provides is bare structure, thus reaching the object of the radiating effect improving ventilated machine, its radiating effect is compared conventional motors and is improved 3% ~ 5%.
Refer to Fig. 1, in one embodiment, stator core 10 comprises the first punching sheet unit 1, second punching sheet unit 2, the 3rd punching sheet unit 3 and the 4th punching sheet unit 4, and these four punching sheet units laminate according to small one and large one sequential segment of external diameter, make the periphery concave-convex surface of stator core 10.Wherein, the external diameter of the first punching sheet unit 1 equals the external diameter of the 3rd punching sheet unit 3; Second punching sheet unit 2 is arranged between the first punching sheet unit 1 and the 3rd punching sheet unit 3, and its external diameter is greater than the external diameter of the first punching sheet unit 1; 4th punching sheet unit 4 is disposed adjacent with the 3rd punching sheet unit 3, and its external diameter is maximum.Certainly, in another embodiment, stator core 10 also can be four the punching sheet unit segmentations increased gradually by external diameter laminate and formed irregularly shaped.
What one of value was carried is, the utility model utilizes the external diameter on stator core between adjacent punching sheet unit different, namely difference in areas each other uses as radiator portion, as long as this stator core in irregular shape is enough to be equal to the transverse direction in conventional motors profile or longitudinal rib sheet, and then increase the area of dissipation of motor, the object improving radiating effect can be reached, so the utility model is not limited with the number and overall dimension that form the punching sheet unit of stator core.
Such as, the external diameter that stator core 10 can comprise the first different punching sheet unit 1 of two overall dimensions setting gradually and the second punching sheet unit 2, first punching sheet unit 1 is less than the external diameter of the second punching sheet unit 2.
Such as, stator core 10 can comprise the first different punching sheet unit 1, second punching sheet unit 2 of three overall dimensions setting gradually and the 3rd punching sheet unit 3, the external diameter of the second punching sheet unit 2 is maximum, and the external diameter of the first punching sheet unit 1 is not less than the external diameter of the 3rd punching sheet unit 3.Or the external diameter of the second punching sheet unit 2 is maximum, the external diameter of the first punching sheet unit 1 is less than the external diameter of the 3rd punching sheet unit 3.
In sum, a kind of ventilated machine of the present utility model, the punching sheet unit of at least two kinds of different overall dimensions is laminated to form the stator core of periphery concave-convex surface by segmentation, namely this stator core in irregular shape is equal to transverse direction in conventional motors profile or longitudinal rib sheet, to increase the area of dissipation of ventilated machine, and then the heat of ventilated machine inside is directly passed to the outside of ventilated machine, not only make its radiating effect compare conventional motors and improve 3% ~ 5%, solve machine operation preferably to dispel the heat limited problem, and its overall dimension is compacter, stock utilization is higher, application scenarios is more extensive, and by motor protective treatment advanced at present, make the degree of protection of motor can meet the corresponding requirements of national standard.
Foregoing; be only preferred embodiment of the present utility model; not for limiting embodiment of the present utility model; those of ordinary skill in the art are according to central scope of the present utility model and spirit; can carry out corresponding flexible or amendment very easily, therefore protection range of the present utility model should be as the criterion with the protection range required by claims.
