Abstract
The utility model relates to an electric machine stator core, it includes stator towards piece, stator ventilation frid, rib, stator clamping ring, towards separating with stator ventilation frid between the piece group, both ends dash the stator clamping ring that piece group tip was equipped with the symmetric placement, the stator all is equipped with the recess of circumference equipartition towards the excircle of piece, stator ventilation frid, stator clamping ring, the stator is arranged in towards the recess of piece, stator ventilation frid, stator clamping ring in and together fixed with corresponding recess to the size of recess and rib overall dimension phase -match, rib. The utility model discloses since the rib setting the stator towards the corresponding recess of piece, stator ventilation frid, stator clamping ring in, increaseed stator towards piece external diameter under the certain condition of height of center to improve the power shelves of corresponding height of center motor. The utility model discloses still relate to the motor including this kind of stator core.
Description
Technical field
The utility model relates to field of motor manufacturing, particularly relates to a kind of motor stator core and motor.
Background technology
At present, the fixing of punching group of motor stator core takes the rib arranging some at punching cylindrical place usually, rib is close to stator punching cylindrical, the two ends of rib are provided with stator pressing ring, and rib and stator punching and stator pressing ring weld together, because rib is arranged in outside stator punching, the external diameter of rib and stator pressing ring is caused to be greater than the external diameter of stator punching, when center height is certain, causes stator punching external diameter less, the power of motor shelves that large corresponding center is high can not be done.In addition, stator core stamping sheet group adopts stator ventilation channel plate to separate isometric segmentation, and because iron core stage casing radiating condition is poorer than iron core two ends, iron core stage casing temperature is higher than iron core two ends, and iron core temperature distributing disproportionation is even.
Utility model content
The purpose of this utility model is to overcome above-mentioned defect, provide a kind of when center high certain can promote corresponding center high power shelves and the stator core of uniformity of temperature profile and comprise the motor of this stator core.
The technical solution of the utility model is: a kind of motor stator core, it comprises stator punching, stator ventilation channel plate, rib, stator pressing ring, separate with stator ventilation channel plate between punching group, the punching group end at two ends is provided with the symmetrical stator pressing ring placed, the cylindrical of described stator punching, stator ventilation channel plate, stator pressing ring is equipped with the groove of circumference uniform distribution, size and the rib overall dimension of described groove match, rib be placed in stator punching, stator ventilation channel plate, stator pressing ring groove in and be fixed together with corresponding groove.
In order to make iron core uniformity of temperature profile, described punching group length is middle from stator core two ends to stator core to be shortened gradually.
The utility model additionally provides a kind of motor, and it comprises stator core, and described stator core is stator core described above.
The beneficial effects of the utility model are, because rib is arranged in the corresponding groove of stator punching, stator ventilation channel plate, stator pressing ring, stator punching external diameter is increased when center height is certain, thus improve the power shelves of respective center height motor, in addition, shorten gradually because stator core stamping sheet group length is middle from iron core two ends to iron core, iron core stage casing is more than iron core two ends air duct, draught area is large, and iron core cooling is more abundant, iron core homogeneous temperature.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
With reference to accompanying drawing, a kind of motor stator core, it comprises stator punching 1, stator ventilation channel plate 2, rib 3 and stator pressing ring 4, separate with stator ventilation channel plate 2 between punching group, described punching group length is middle from stator core two ends to stator core to be shortened gradually, the punching group end at two ends is provided with the symmetrical stator pressing ring 4 placed, described stator punching 1, stator ventilation channel plate 2, the cylindrical of stator pressing ring 4 is equipped with the groove of circumference uniform distribution, size and rib 3 overall dimension of described groove match, rib 3 is placed in stator punching 1, stator ventilation channel plate 2, weld with corresponding groove and be fixed together in the groove of stator pressing ring 4.
The utility model additionally provides a kind of motor, and it comprises stator core, and described stator core is stator core described above.
