Abstract
The utility model discloses a strip wound core of an electric motor stator. The strip wound core comprises multiple core units, wherein each core unit is I-shaped, and the outer side of the I-shaped outer cross section and the inner side of the I-shaped inner cross section are arc-shaped. The outer sides of the I-shaped outer cross sections of adjacent core units are connected through an arc-shaped connection side so that the core units are connected in series to form a strip shape. The strip wound core provided by the utility model has simple structure, can be prepared conveniently and is convenient in automatic winding, automatic winding at multiple ends can be realized, one stator can be quickly and automatically wound at one time, manual winding insertion is not needed, and welding joints do not exist. Meanwhile, the processing precision of the stator core is improved, the strain in the bending process of the core is reduced, the magnetic property is maintained, the core utilization rate is improved, the material cost and labor cost are reduced, and the mould blanking technology and the linear winding technology of multiple slots are changed. The strip wound core has the advantages of automatic full-slot winding, small notch, high efficiency, low cost, good heat dispersion, strong overload capacity, large torsion, no need of welding and the like.
Description
Technical field
It is unshakable in one's determination to the present invention relates to a kind of motor stator coiling, is that a kind of motor stator bar shaped coiling is unshakable in one's determination specifically.
Background technology
Existing motor stator coiling is unshakable in one's determination, is the garden shape, mostly is the single piece that the Cylinder punching press forms greatly, and manpower rolls off the production line, interior coiling can not automation, and groove Full leads low, and efficient is low, the manpower welding, and the cost height, the heat radiation difficulty, overload capacity is little, and torsion is little.China's utility model patent (Granted publication CN201156696Y) discloses a kind of electric vehicle brushless DC motor stator, form by a plurality of stator tooth unit splicings, side at the interior nose circle of stator tooth unit is provided with dome, the another side has shrinkage pool, and the dome of each stator tooth unit is flush-mounted in assembled electric vehicle brushless DC motor stator in the shrinkage pool of adjacent stators tooth unit.Before assembly unit, directly on the stator tooth unit, wind the line.Therefore, this motor stator, it is very inconvenient to wind the line, and is difficult for realizing the mechanical automation coiling.
The utility model content
Problem to be solved in the utility model is to overcome the defective that prior art exists, and provides a kind of motor stator bar shaped coiling unshakable in one's determination, and it is simple in structure, easy to prepare, is convenient to the automation coiling.
Motor stator bar shaped coiling is unshakable in one's determination, constitute by some core unit, core unit is an I shape, the inner edge of plane of structure is a circular arc in the outside of the outer plane of structure of its I-shaped and the I-shaped, it is characterized in that: the outside of the outer plane of structure of the I-shaped of each adjacent core unit connects with the circular arc fillet, and it is linear that each core unit is connected into; Outside core unit, establish groove on plane of structure side, outside core unit, establish projection on another side of plane of structure, the position of groove and projection is corresponding mutually, and when motor stator bar shaped coiling iron core was closed into cylinder, adjacent grooves and projection fastened mutually.
The utility model motor stator bar shaped coiling is unshakable in one's determination, for some punching press laminations are laminated, again it is closed into cylinder after the coiling, forms motor stator.It is simple in structure, easy to prepare, is convenient to automation coiling, has therefore changed the inner artificial inserting-coil process method of motor stator, can bull automatically row around, stator is once fast automatic need not to roll off the production line by manpower around intact, does not have welding point.Improve the stator core machining accuracy simultaneously, the strain when reducing bending machining unshakable in one's determination keeps magnetic characteristic constant, improves utilance unshakable in one's determination, reduces material cost and human cost, changes the technology of blanking die and the straight line wire winding technology in multiple-grooved hole.Core unit I shape inner edge is qualitative change, Ke Zi Dong Full groove coiling, and notch is little, the efficient height, cost is low, and it is excellent to dispel the heat, and overload capacity is strong, and torsion is big, advantage such as need not weld.
Description of drawings
Fig. 1 is the utility model motor stator bar shaped coiling core construction schematic diagram;
Fig. 2 is the utility model motor stator bar shaped core unit structural representation unshakable in one's determination that winds the line;
Fig. 3 is the utility model motor stator bar shaped coiling cylinder (motor stator) structural representation that forms unshakable in one's determination.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, 2, motor stator bar shaped coiling is unshakable in one's determination, constitute by some core unit, core unit is an I shape, the inner edge 5 of plane of structure 3 is a circular arc in the outside 4 of the outer plane of structure 2 of its I-shaped and the I-shaped, it is characterized in that: the outside 4 usefulness circular arc fillets 6 of the outer plane of structure of the I-shaped of each adjacent core unit connect, and it is linear that each core unit is connected into; Outside the core unit I-shaped, establish groove 8 on plane of structure side, outside the core unit I-shaped, establish projection 9 on another side of plane of structure, the position of groove and projection is corresponding mutually, when motor stator bar shaped coiling iron core is closed into cylinder (as shown in Figure 3), adjacent grooves and projection fasten mutually.When the linear coiling iron core of motor stator was closed into cylinder, described circular arc fillet can change the outer plane of structure adaptability to changes of I-shaped unshakable in one's determination.Outside part core unit I-shaped, offer fixing hole 1 on the outside of plane of structure.
When preparing this motor stator bar shaped coiling iron core, at first the some upright core sheets of punching press are stacked with some laminations then, wear the rivet riveting and decide in rivet hole 7.Again it is closed into cylinder after the coiling, forms motor stator.
