Description
Technical field
The utility model relates to a kind of motor stator punching.
Background technology
The some teeth portion that current stator punching comprises ring-shaped yoke portion and stretches out toward inner side from ring-shaped yoke portion, between adjacent two tooth portions, form line embedding groove, but the physical dimension of stator punching differs, the quantity of line embedding groove respectively has difference, through magnetic circuit computational analysis, there is following several deficiency in these stator punchings: 1) area of line embedding groove is excessive, causes line embedding groove area utilization lower, so also cause the utilance of silicon steel sheet lower, cause the wasting of resources to a certain extent; 2) magnetic leakage factor of the stator core that stator punching is made is larger, causes the maximum moment of motor and starting torque to decline, and during motor operation, temperature is higher, causes the useful life of motor shorter, thereby has influence on motor reliability of operation; 3) magnetic density of ring-shaped yoke portion and tooth portion is inhomogeneous, easily causes vibration, and produce noise during motor operation.
Utility model content
Main purpose of the present utility model is to provide a kind of motor stator punching, and this is simple in structure, and the magnetic density of stator punching is moderate, and utilance is high, reliable operation.
Above-mentioned purpose is achieved by the following technical solution:
A kind of motor stator punching, comprise a plurality of stator teeths that annular stator yoke portion and the center position from stator yoke portion toward stator punching extend, between adjacent two stator teeths, form line embedding groove, and described stator punching has the interior circular hole of hollow, it is characterized in that: the diameter of stator punching is between 78.5mm to 92.0mm, the diameter of interior circular hole is between 47.0mm to 62.5mm, the width of stator teeth is between 6.8mm to 8.0mm, and the width of rebate of line embedding groove is between 1.8mm to 2.7mm.
Above technical scheme can be further improved by following measures:
The quantity of stator teeth described above is 12, and stator teeth is circumferentially evenly arranged in stator yoke portion inner side.
On the outer ledge of stator yoke portion described above, offer some avoiding hollow grooves.
Each technical measures can be selected a use above, and yet use capable of being combined, as long as that does not form conflict between levying.
The utility model compared with prior art tool has the following advantages:
1) diameter of stator punching is between 78.5mm to 92.0mm, the diameter of interior circular hole is between 47.0mm to 62.5mm, the width of stator teeth is between 6.8mm to 8.0mm, the width of rebate of line embedding groove is between 1.8mm to 2.7mm, the quantity of stator teeth is 12, this is simple in structure, groove area is moderate, effectively improved the utilance of silicon steel sheet, and the magnetic leakage factor of stator is little, maximum moment and the starting torque of motor are larger, and the magnetic density of stator punching is moderate, utilance is high, reliable operation;
2) on the outer ledge of stator yoke portion, offer some avoiding hollow grooves, simple in structure, the convenient bolt for mounted motor passes from the outer ledge of stator yoke portion.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model motor stator punching.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model is a kind of motor stator punching, comprise a plurality of stator teeths 2 that annular stator yoke portion 1 and the center position from stator yoke portion 1 toward stator punching extend, between adjacent two stator teeths 2, form line embedding groove 3, and described stator punching has the interior circular hole of hollow, the diameter D of stator punching is between 78.5mm to 92.0mm, the diameter d of interior circular hole is between 47.0mm to 62.5mm, the width L1 of stator teeth 2 is between 6.8mm to 8.0mm, the width of rebate L2 of line embedding groove 3 is between 1.8mm to 2.7mm, improve the area utilization rate of line embedding groove 3, improve the service efficiency of silicon steel sheet, reduce the magnetic leakage factor of stator, make the magnetic density of stator moderate.The quantity of stator teeth 2 is 12, and stator teeth 2 is circumferentially evenly arranged in stator yoke portion 1 inner side, facilitates machine embedding coiling, improves winding efficiency.On the outer ledge of stator yoke portion 1, offer some avoiding hollow grooves 11, the convenient bolt for mounted motor passes from avoiding hollow groove 11.
The diameter D of preferred stator punching is between 83.5mm to 86.0mm.
In preferred, the diameter d of circular hole is between 55.0mm to 56.5mm.
The width L1 of preferred stator teeth 2 is between 7.3mm to 7.5mm.
The width of rebate L2 of preferred line embedding groove 3 is between 2.2mm to 2.3mm.
Therefore, the area of line embedding groove is moderate, improves line embedding groove area utilization, and the magnetic leakage factor of the stator core that stator punching is made is simultaneously less, and maximum moment and the starting torque of motor are large.
Above-described is only execution modes more of the present utility model.For the person of ordinary skill of the art, not departing under the prerequisite of the utility model creation design, can also make some distortion and improvement, these all belong to protection range of the present utility model.
