Description
Technical field
The present invention relates to a kind of motor stator punching, belong to motor processing technique field.
Background technology
If the stator of motor is formed by stacking by dry plate stator punching, but the structure of existing stator punching managing not
Think so that stator teeth and yoke portion magnetic density are higher, and cause the power output of motor on the low side.Reality with new Energy Efficiency Standard
Executing, in order to make existing motor meet the standard of new efficiency, producer generally uses increase iron core folded thick and increases winding copper consumption,
So causing motor volume to increase, the raw material usage amount such as single motor iron and copper consumption is substantially improved, and considerably increases
The production cost of motor.
Content of the invention
It is an object of the invention to provide a kind of efficient motor stator punching, in the feelings not changing stator punching excircle dimension
Under condition, by the adjustment to stator punching teeth portion and yoke portion size, reach to improve the delivery efficiency of motor and saving raw material
The purpose of consumption.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of efficient motor stator punching, the middle part of stator punching is provided with circular hole in hollow, the radial direction of circular hole in hollow
Being evenly arranged with multiple punching groove, the lateral surface of stator punching is spaced apart and is provided with round edge and trimming；The size of described round edge is φ
95mm, the distance of relative two trimmings is 94mm, and in hollow, the size of circular hole is φ 60mm, the chi of place, the groove top circle of punching groove
Very little for φ 81mm；The a width of 2mm of notch of described punching groove, a height of 0.6mm of notch, groove shoulder height is 0.7mm, the facewidth of stator punching
For 3.4mm.
The number of described punching groove is 24.
Described punching groove be shaped as peariform slot.
The present invention is on the basis of the stator punching of existing identical excircle dimension, and emphasis is to hollow inner circle hole dimension, punching groove
The facewidth of the size of place, groove top circle and stator punching is adjusted, in the case of not increasing original motor volume, and will
The delivery efficiency of motor promotes 5%, decreases with copper with by raw-material usage amounts such as iron simultaneously, reduce further motor
Production cost.
Below by way of the drawings and specific embodiments, the present invention is further elaborated.
Brief description:
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of punching groove.
Detailed description of the invention:
In conjunction with shown in Fig. 1 and Fig. 2, a kind of efficient motor stator punching that the present invention provides, including stator punching 1, stator rushes,
The middle part of 1 is provided with circular hole 5 in hollow, and in hollow, the radial direction of circular hole 5 is uniformly arranged 24 punching grooves 4, and punching groove 4 is pyriform
Groove, the lateral surface of stator punching 1 is spaced apart and is provided with round edge 3 and trimming 2；The size of round edge 3 is φ 95mm, relative two trimmings 2
Distance be 94mm, in hollow, the size of circular hole 5 is φ 60mm, and the size of the place, groove top of punching groove 4 circle is φ 81mm；Punching
The slot opening C of groove 4 is 2mm, and notch height E is 0.6mm, and groove shoulder height F is 0.7mm, and facewidth H of stator punching 1 is 3.4mm.
Technique scheme is on the architecture basics of the stator punching 1 of existing same round edge 3 size, by hollow inner circle
Facewidth H of hole 5 size, the size of place, punching groove 4 groove top circle and stator punching 1 is adjusted, it is achieved improve motor output
Efficiency and the raw-material purpose of saving.
Wherein, on the basis of ensureing round edge 3 size not changing original stator punching 1, by the size of circular hole in hollow 5
It is adjusted to present φ 60mm from original φ 55mm, the size of place, the groove top circle of punching groove 4 is adjusted from original φ 83mm
Whole for present φ 81mm, the groove being equivalent to reduce punching groove 4 is high, so adjusts, save manufacture stator punching 1 use iron
Amount.During it is known that the groove height of punching groove 4 is higher, the magnetic circuit area in yoke portion can be caused to reduce, easily there is saturation state in magnetic circuit,
But, groove is high reduces the groove area that also can reduce punching groove 4, makes copper factor improve, and therefore, the high adjustment of film trap 4 groove that liquidates needs
Consider, it is impossible to make copper factor too high that coiling difficulty otherwise occurs comprehensively.Through repeatedly calculating and contrast test, Wo Menfa
Existing groove Gao Ruo changes in less scope, then less on loss impact, therefore, we use and are slightly increased circular hole 5 in hollow
Size and the size of place, the groove top circle being slightly reduced punching groove 4 high to reduce groove, select one suitably sized, make groove face
Long-pending reduction, properly increases copper factor, can increase the magnetic flux density of winding, can also save the copper consumption of winding, but will not lead
Cause copper factor too high.
On the basis of above-mentioned Adjusted Option, increase facewidth H of stator punching 1 further, be adjusted to existing from original 3mm
3.4mm.Facewidth H increases, and the groove width of punching groove 4 is reduced by, and groove area is also relatively reduced, and therefore, the amplitude of adjustment is not yet
Easily excessive.Suitably increase facewidth H, the mechanical strength of stator punching 1 teeth portion can be improved, especially for determining of small size multiple-grooved
For sub-punching, its effect is fairly obvious.Facewidth H increases, and groove number is constant, and groove width size is reduced by, and makes magnetic circuit be not susceptible to
Morning saturated, can reduce the loss of saturation of magnetic path, but groove area also can be made to reduce.
By the analysis of the stator punching 4 to this excircle dimension, calculating and test of many times, it has been found that setting of original size
Counting structure, there is the not high problem of copper factor in it, copper factor is low, and wire can be made to occur loosening in groove, fragile insulating barrier, groove
In space also many, due to air conduction difference, affect the heat radiation of coil, the temperature rise of motor can be high, and therefore, we are by by upper
State in scheme three parameters and could be adjusted to reach to properly increase the purpose of copper factor, the structural parameters of stator punching 1 simultaneously
Typically all interactional, do not isolate each other, be not simply to adjust certain parameter to can be achieved with desired technology
Effect, the lifting of a performance is generally along with the decline of another one performance, and therefore, the adjustment of each parameter needs pool to examine
Consider.Such scheme is based on this thought, makes overall plans, and have chosen suitable adjustable parameter and is adjusted, and has both reached to improve
The purpose of copper factor, will not occur again the problem that copper factor is too high.Use motor and the original structure of the stator punching 1 of the present invention
Motor compare, under the premise of identical power output, the electric efficiency of the present invention can promote 5%, can also save the former of motor
Materials'use amount, reduces the beneficial effect of manufacturing cost.
Above example is only in order to illustrate technical scheme and unrestricted, and those of ordinary skill in the art are to this
Bright technical scheme made other modification or equivalent, without departing from the spirit and scope of technical solution of the present invention,
All should cover in scope of the presently claimed invention.
