Arranged relative, to form the linear type winding coil unit of alternately laminated arrangement.
Further, to improve electric efficiency, reduction weight, many existing literatures use some novel loop constructions,
These schemes can reduce motor weight and loss to a certain degree, and structure is simple, but not effectively reduce eddy-current loss；Such as figure
Shown in 7 (a), using flat type copper wire coiling winding, copper section accounting is promoted obviously, and direct current copper loss is remarkably decreased, however iron-core-free
Machine winding is exposed in the secondary magnetic of alternation, and the biggish normal direction width of flat type copper wire causes high exchange copper loss, cause be
Efficiency of uniting is less than 85%；To inhibit to exchange copper loss, many existing literatures use Litz line coiling armature, as shown in Fig. 7 (b), lead to
Thermoplastic shaping after coil winding is crossed, but correspondingly copper section accounting can be decreased obviously, inter-air space utilization rate is higher than routine Litz
Line scheme, but copper section accounting is still lower, and less than 50%, direct current copper loss reaches twice of flat type copper wire scheme.As shown in Fig. 7 (c), this
Invention proposes a kind of sheet type loop construction, because to penetrate direction parallel for band-like copper foil face and magnetic field, has effectively separated vortex road
Diameter, it is suppressed that winding eddy current loss.

It is cut by copper sheet or copper foil winds and to form sheet type coil, the linear type concentratred winding structure that multiple arranged adjacents are formed,
Or the linear type winding construction that multiple alternately laminated arrangements of sheet type coil are formed.
Embodiment 1: copper sheet cutting processing
Fig. 8 show the processing flow of copper sheet patterning method: (1) copper sheet being cut into diagram rectangular module；(2) it uses
Gained rectangular module in step (1) is pressed into diagram shape by mold, can then save this step according to concentratred winding method；
(3) using Precision Machinings modes such as wire cuttings, copper sheet is cut into line made of similar copper foil winding band-like with one heart along normal direction
Circle；(4) the linear type winding construction for forming the alternately laminated arrangement of the coil, and the winding module that will be arranged using fixture
Sizing, and dipping lacquer does turn-to-turn insulation processing；(5) winding installation, positioning, wiring；(6) epoxy resin or other high thermal conductivity systems are used
Several nonmetallic materials form secondary windings integrated encapsulation.
This method winding cuts to obtain using monolith copper sheet, by controlling cutting accuracy, under the premise of guaranteeing insulation,
Close-packed arrays between achievable conductor, inter-air space copper section accounting can reach even more than flat type copper wire coiling, to be promoted entire
The utilization rate of winding space, and then reduce resistance, electric efficiency is promoted, motor weight is reduced.In addition, because copper sheet is cut along normal direction
It cuts, the width of every circle copper wire, that is, copper foil can be controlled in the reasonable scope, so as to avoid larger exchange copper loss.

The form of insulating paper is wound, and insulation can be carried out simultaneously in winding process using this scheme；(2) as shown in Figure 10, it is wound into
After type, the section loop A A ' is rectangle, and winding module can be obtained after grey parts are cut off；(3) dipping lacquer after 1 coil of scheme need to be unfolded,
Molding is rewound again, and scheme 2 only needs whole dipping lacquer to do insulation processing since turn-to-turn has insulating paper；(4) winding is installed, is fixed
Position, wiring；(5) using the nonmetallic materials of epoxy resin or other high thermal conductivity coefficients, secondary windings integrated encapsulation is formed.
Because copper foil and insulating paper thickness are controllable, coiling and molding can obtain high copper section in the case where guaranteeing insulation and account for together
Than, and copper foil plane with it is tangential parallel, then magnetic field is minimum across section, and exchange copper loss can be effectively suppressed.In the embodiment of the present invention
