Compared with the prior art, the utility model discloses effectively promote the back -emf of drag cup motor to further promote the performance of motor.
Description
Technical field
The utility model relates to a kind of winding, especially relates to a kind of drag cup winding of integrated distribution.
Background technology
In traditional hollow-cup motor winding process, be generally wound on winding former 1 uniformly by conductor 2, tapping 3 is positioned at coil two ends, sees Fig. 1, the flat and hot Cheng Yuanhou in hot pressing, forms drag cup winding.This winding arrangement mode, because conductor is spatially evenly distributed in 120 °, when the back-emf vector on conductor projects to the midline, will much larger than the vector of both sides by submedial vector back-emf utilance.
When the number of turn that is often in series of drag cup winding rises or wire diameter size becomes large, due to the limited length of winding former, same layer conductor can not be wound in one deck spatially, therefore unavoidably there will be the phenomenon of conductor position staggered floor, see Fig. 2.In addition, consider that the precision of the stroke of coil winding machine also may cause staggered floor phenomenon.2-2 in Fig. 2 is the conductor after staggered floor, and 2-1 is normal conductor.For conductor 2-2, the conductor 2-2 of conductor 2-1 and staggered floor is evenly distributed in 120 ° (including but not limited to 120 °) by traditional method for winding, but the conductor of staggered floor is distributed in winding uniformly, effectively can not utilize the back-emf that the conductor of staggered floor produces, the back-emf that the conductor away from winding center line place produces is less than the back-emf that the conductor near winding center line produces.
Utility model content
The purpose of this utility model is exactly provide a kind of drag cup winding of integrated distribution to overcome defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of drag cup winding of integrated distribution, it is characterized in that, comprise staggered floor conductor, normal conductor and tapping, described staggered floor conductor concentrates on the centre position of winding, described normal conductor is distributed in the both sides of staggered floor conductor, described tapping is positioned at the both ends of normal conductor, and described winding mid portion density is greater than normal conductor.
The quantity of described staggered floor conductor is 1/10 to 1/2 of normal conductor.
Preferably, the quantity of described staggered floor conductor is 1/4 of normal conductor.
The conductor density of this winding is diminished to both sides gradually by centre.
The number of conductors of described staggered floor conductor is directly proportional to the internal diameter of winding after volume circle.
Compared with prior art, the utility model has the following advantages:
1) the method is based on hollow-cup motor back-emf polar plot, proposes, by reducing coil both sides away from the conductor density of winding former center, to be increased to hub of a spool part.By the method, can not change at electric machine structure, under umber of turn does not change prerequisite, effectively promote the back-emf of hollow-cup motor, and the performance of further lifting motor;
2) number of conductors of coil mid portion increase, after being subject to rolling up circle, the restriction of winding size, prevents from infinitely expanding other potential safety hazards brought;
3) the method does not need scrap build few, by debugging the coiling program of coil winding machine, having and being easy to Project Realization feature.
Accompanying drawing explanation
Fig. 1 is traditional hollow-cup motor winding construction schematic diagram;
Fig. 2 is the winding construction schematic diagram of existing conductor position staggered floor;
Fig. 3 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
As shown in Figure 3, a kind of drag cup winding of integrated distribution, comprise staggered floor conductor 2-2, normal conductor 2-1 and tapping 3, described staggered floor conductor 2-2 concentrates on the centre position of winding, described normal conductor 2-1 is distributed in the both sides of staggered floor conductor 2-2, described tapping 3 is positioned at the both ends of normal conductor 2-1, and the wire density of the winding mid portion at described staggered floor conductor 2-2 place is greater than normal conductor 2-1.
The quantity of described staggered floor conductor 2-2 is 1/10 to 1/2 of normal conductor 2-1.Preferably, the quantity degree of described staggered floor conductor 2-2 is 1/4 of normal conductor 2-1.
The conductor density of this winding is diminished to both sides gradually by centre.The number of conductors of described staggered floor conductor 2-2 is directly proportional to the internal diameter of winding after volume circle.
The utility model proposes and concentrate near hub of a spool by conductor, the coil of formation occurs: sparse, concentrates, sparse conductor distribution.Easily know according to the analysis of back-emf polar plot, staggered floor conductor 2-2 is concentrated in the middle of coil, the back-emf utilance of these conductors can be promoted.Reduce the density on coil both sides, the conductor of corresponding amount is increased to coil mid portion simultaneously, under identical electric machine structure and the number of turn, effectively can promotes the back-emf of drag cup, lifting motor electromagnetic performance.But the number of conductors that coil mid portion increases is subject to the restriction of rolling up the rear winding inner diameter size of circle.
