Detailed description of the invention
Hereinafter, the example to embodiments of the present invention, as a example by axial-gap rotary electric machine
Illustrate with reference to accompanying drawing, but as long as being to use to form the soft magnetic materials stacking of rectangular flat plate shape
The electric rotating machine of iron core, then be not limited to axial-gap, it is also possible to be applicable to radial gap type etc..
Embodiment
[embodiment 1]
Illustrate to use iron core and the knot of stator tooth of the soft magnetic materials of the present invention with Fig. 1～3,5～7
One embodiment of structure.Wherein, Fig. 4 be for the present embodiment carry out contrasting with reference to figure.
Fig. 1 is that the structure of the axial-gap rotary electric machine to the soft magnetic materials using the present invention is entered
The figure of row explanation.The electric rotating machine 10 of axial-gap have on discoideus parts 21
Be configured with on circumferencial direction multiple permanent magnet 20 rotor 50, in a circumferential direction be configured with multiple
Including iron core 31 stator tooth 30 stator 60, in order to make rotor 50 and stator 60 with one heart
The rotary shaft 70 configured on circle, the shell 80 depositing them.
Wherein, it is not limited to permanent magnet 20, as long as produce the magnet of magnetic force, it is also possible to put
It is changed to other magnet or electromagnets etc..
Stator tooth 30 as in figure 2 it is shown, be energized and excitation by the electric wire 33 that its periphery is wound,
Make to produce between permanent magnet 20 and stator tooth 30 gravitation, by making different stator tooths 30 continuous
Ground excitation and make, between rotor 50 and stator 60, rotary motion occurs.Because stator 60 is by multiple
Stator tooth 30 is constituted, so each stator tooth 30 individually arranges the iron core 31 of bulk.
Fig. 2 is the figure of the structure that stator tooth 30 is described.Stator tooth 30 has iron core 31, insulation
Body 32, electric wire 33.Insulator 32 configures with the insulation of electric wire 33 in order to ensure iron core 31
Around iron core 31, at the live wire wound around 33 of insulator 32.Insulator 32 uses
One or more pieces insulating papers or the laminal resin material etc. of below thickness 1mm, electric wire 33
Use the wire rod that cross section is generally circular or cross section is substantially rectangular with copper or aluminium etc. as mother metal.
Fig. 3 is the figure of the structure of the iron core that stator is described.Iron core 31 is by with iron, cobalt or nickel as mother
The laminate structure 1 of the lamellar soft magnetic materials of material is constituted, and this laminate structure 1 can be by right
Lamellar soft magnetic materials is cut to the rectangular flat plate shape of length L, arbitrary width B respectively
Material stacking piecewise, but in the present embodiment, by have same length L, width B rectangular
Shape tabular thin plate multi-disc overlaps to form the soft magnetic materials block 2 of approximately parallelepiped body, and then makes width B
Different soft magnetic materials blocks 2 is constituted by the number stacking of regulation.
Each rectangular flat plate shape thin plate, is to not make laminal soft magnetic materials bend
Deformation, presses one or more pieces cut-outs every with cutting machine etc., in the case of multi-disc is cut off simultaneously,
In order to make the residual stress along with being breaking at plane of disruption generation will not iron loss be impacted, also root
Thickness and the cutting machine margining tablet number of use according to soft magnetic materials.
So, because making iron core 31 is soft magnetic materials block 2 stackings different for width B to be formed
Laminate structure 1, so when being cut to each rectangular flat plate thin plate, it is possible to do not make soft magnetic materials
Shifting ground becomes the arbitrary cross sectional shape such as circular, generally polygonal or substantially elliptical.
As it has been described above, iron core 31 by by electric wire 33 is energized produce magnetic flux excitation time, because of
Vortex flow and iron core 31 that the inside of iron core 31 produces add the residue that the strain produced man-hour causes
Stress etc. and hinder excitation to produce loss, the efficiency of electric rotating machine reduces.
Such as, such as the situation with reference to shown in figure, to the iron core 31 that lamination riveting manufactures of Fig. 4
Under, the caulking part of the laminate structure 1 of soft magnetic materials produces strain, and loss increases.
On the other hand, as shown in this embodiment, rectangular flat plate shape thin plate multi-disc will be made overlapping and
In the iron core 31 that soft magnetic materials block 2 stacking of the approximately parallelepiped body become obtains, it is processed as each rectangular
During shape tabular thin plate the plane of disruption produce strain less, so with the iron core manufactured by riveting
31 compare and can reduce loss.
Additionally, in the iron core with riveting projection as shown in the reference example of Fig. 4, because
Soft magnetic materials is made to be molded by punching processing, so producing more leftover pieces, on the other hand,
The iron core of the present invention makes soft magnetic materials cut off respectively to be processed as rectangular flat plate shape and be shaped,
So the generation amount of leftover pieces is few, it is possible to expect that the usage amount of soft magnetic materials is cut down and parts expense
Cost cutting.
Additionally, make the direction of soft magnetic materials block 2 stacking be not limited to a direction, as long as such as this reality
Execute shown in example, for substantially becoming the direction of 90 degree with direction of principal axis in axial-gap rotary electric machine,
On the other hand, for substantially becoming the direction of 90 degree with radial direction in radial gap type electric rotating machine,
Just can change stacked direction.
As an example, manufacturing cross section in axial-gap rotary electric machine is generally trapezoidal iron core
In the case of, it is possible to enumerate the upper end generally trapezoidal with cross section as shown in Figure 5A and go to the bottom vertical
Direction, the upper end generally trapezoidal with cross section as shown in Figure 5 B and go to the bottom parallel direction or as figure
The directions that hypotenuse generally trapezoidal with cross section shown in 5C is parallel etc. are as stacked direction.
Fig. 6 A and Fig. 6 B is to illustrate to arrange substantially chamfer shape (R shape) in the corner of iron core
In the case of the figure of structure of stator tooth.The corner 36 of the iron core 31 shown in Fig. 6 A is acute angle
In the case of generally trapezoidal, than electric wire 33, the corner 36 of iron core 31 becomes allows that bending radius is more
During little acute angle, there is the situation producing gap between electric wire 33 and insulator 32 and iron core 31.
In the case of electric wire 33 can not bend along corner 36, iron core 31 is whole relative to stator tooth 30
The ratio of body volume reduces because of the gap between electric wire 33 and insulator 32 and iron core 31, can
Loss can be increased.
Additionally, in the case of covering iron core 31 in order to the insulator 32 that insulating paper is material, because of
It is acute angle for corner 36, so insulator 32 may be damaged.Now, by regulation stacking
The thickness of soft magnetic materials block 2 and width B, make corner 36 become substantially chamfering as shown in Figure 6B
Shape ground stacking, alleviates the load to insulator 32 and prevents breakage, and make electric wire 33 edge
Corner 36 to bend, the gap between electric wire 33 and insulator 32 and iron core 31 reduces, energy
Enough make iron core closely configure, obtain losing less stator tooth 30.
Fig. 7 is the structure illustrating to change the stator tooth in the case of the thickness of soft magnetic materials block 2
Figure.The thickness T of soft magnetic materials block 2 by being cut off by soft magnetic materials different for thickness, can incite somebody to action
Soft magnetic materials multi-disc overlap cut off or make the material stacking after cutting off with many times of same widths B and
Change.When making soft magnetic materials block 2 stacking constitute iron core 31, the thickness of soft magnetic materials block 2
T needs not to be certain.
