Abstract
The utility model relates to the technical field of a motor, aiming at providing a uniformly-distributed small trough-shaped stator punching sheet of the motor. The center of the punching sheet is provided with a round rotor hole; a plurality of trough-shaped holes enwound by enameled wire are uniformly distributed surrounding the rotor hole; the external profile of the punching sheet is a squareor a rectangle; in the four edges of the square or the rectangle, at least one edge consists of multi line segments that are not in the same line, thus forming a layered structure degressive from themiddle part to two sides. The stator punching sheet has the advantages that the magnetic flux density on the stator can be distributed more uniformly and the efficiency of the motor can be improved.
Description
Technical field
The utility model relates to technical field of motors, specifically, is a kind of motor stator punching of uniform little flute profile.
Background technology
Motor of the prior art, especially hermetically sealed refrigerating compressor unit substantially all are to adopt monopole asynchronous motor, and the profile of its stator punching also all is circular structure generally, is made by silicon steel sheet.All can have the rotor hole of a circle at the center of these stator punchings, the surrounding rotor hole is evenly equipped with several flute profile holes that install around enamelled wire, installs around the main winding and the auxiliary winding of motor in the hole respectively; The magnetic line of force that these windings produced passes through from silicon steel sheet, forms a magnetic loop.The slotted hole that generally is located on the stator is general dark and big, and the notch size is broad also; For the stator of circle, slotted hole size all around is consistent; And for some semicircle ens that occurred in recent years, four jiaos of stator punchings that have the square contour of transition arc, such as the stator punching shown in Fig. 2, its slotted hole generally just distributes around endoporus as two kinds of big and little specifications.Above-mentioned these motor stator punchings are having following defective in shape at present:
1, the general broad of the size of notch makes slot leakage lead increase, and therefore electric efficiency can not get improving;
If 2 adopt circular punching, the face shaping of circle makes that its useless damage on the design discharge is more, causes waste of material big, and the motor manufacturing cost is increased;
If 3 adopt the stator punching of rectangle outline, because the yoke portion width of rectangle straight portion can cause the former magnetic flux density to influence the power output of motor much larger than the latter much smaller than the width of its foursquare arc part; And magnetic flux density inhomogeneous also cause the motor local pyrexia easily, influences the overall performance of motor.
The utility model content
The purpose of this utility model is in order to overcome above-mentioned deficiency of the prior art, a kind of motor stator punching of uniform little flute profile is provided, by the yoke portion width of body straight portion in the increase stator punching, thereby impel the even of magnetic flux distribution, promote efficiency of motor greatly.
To achieve these goals, the technical solution of the utility model is:
A kind of motor stator punching of uniform little flute profile, the center of punching has circular rotor hole, the surrounding rotor hole is evenly equipped with several flute profile holes that install around enamelled wire, the appearance profile of described punching is square or oblong-shaped, in the square or rectangular four edges, at least one limit has been made of the structure of a level shape of successively decreasing to both sides from the centre several sections line segments on same straight line not.
As a kind of improvement of the present utility model, described slotted hole is divided into large, medium and small length different more than three kinds, and the size of length makes that formed yoke is high behind each slotted hole and equates.
As a kind of improvement of the present utility model, the notch size of described slotted hole is between 1.2mm～1.6mm.
As a kind of improvement of the present utility model, the notch of described slotted hole is of a size of 1.4mm.
As a kind of improvement of the present utility model, the quantity of described slotted hole is 24.
Selection suitable dimensions parameter under the explained hereafter condition is being satisfied in the design that the utility model is taked reasonably optimizing to the shape and the profile of motor stator punching.This appearance profile is square or rectangle, and its four edges is made of several sections line segments on same straight line not respectively, the low level shape structure in high both sides in the middle of forming, therefore, each segment all does well out of the stamping knife flushing technology, and finished product is effective, and the useless damage of square punching in the discharge design is low; The periphery of this level shape structure can strengthen the yoke portion width in the middle of the body straight portion in the stator punching; On the other hand, by suitably reducing to be positioned at the length of the locational slotted hole in middle, also play the effect of further increasing yoke portion width; These two position is by meticulously configuration, makes that formed yoke height all equates behind each slotted hole, thereby impels the magnetic flux density on the stator evenly to distribute, the idle energy consumption of minimizing motor; In addition, slotted hole also reduces on the notch size further, the air gap that guarantees rotor and stator between 0.25mm～0.29mm, thereby also can promote electric efficiency greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is the slotted hole distribution schematic diagram of the square stator punching in the conventional art.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1, the motor stator punching of uniform little flute profile of the present utility model, made by silicon steel sheet, the center of punching has circular rotor hole, and the surrounding rotor hole is evenly equipped with 24 slotted holes that install around enamelled wire, the specification of dividing large, medium and small three kinds of different lengths, be vat 1, middle groove 2 and the sulculus 3 among Fig. 1, the three evenly distributes around circumference, and the width dimensions of the notch 4 of slotted hole is 1.4mm, so both satisfy the requirement of explained hereafter, can improve efficiency of motor greatly again.The appearance profile of this motor stator punching is approximate square shape, the useless damage when designing discharge to reduce; Article four, in the periphery, every limit is made of several sections line segments on same straight line not respectively, form a kind of structure of level shape of successively decreasing to both sides from the centre, the low level shape structure in high both sides promptly, this shape has been widened the yoke portion width in the middle part, therefore can be so that the yoke height that forms behind each slotted hole is basic identical.In this specific embodiment, specially also show as the flute profile size of first groove 5 of the vat 1 that will originally design, redesign little more much than other vat 1, and measure-alike with middle groove 2, like this after the change, further strengthen the yoke portion width of original middle straight portion, make the magnetic flux density of stator obtain easily distributing more uniformly.
The motor gas-gap of conventional refrigerator compressor is all between 0.3mm～0.45mm, adopt the motor of the motor stator punching of uniform little flute profile of the present utility model, the notch size is reduced, its motor gas-gap also can be reduced between 0.25mm～0.29mm, make leakage field still less, electric efficiency promotes greatly.
At last, it should be noted that above what enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and a lot of distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection range of the present utility model.
