Embodiment
Below, to the example of embodiments of the present invention, taking axial-gap rotary electric machine as example is with reference to brief description of the drawings, but as long as using the electric rotating machine of the iron core of the stacked formation of soft magnetic material of rectangular flat plate shape, be not limited to axial-gap, also can be applicable to radial gap type etc.
Embodiment
[embodiment 1]
Use an embodiment of the iron core of soft magnetic material of the present invention and the structure of stator tooth with Fig. 1～3,5～7 explanations.Wherein, Fig. 4 is the reference diagram for contrasting with the present embodiment.
Fig. 1 is the figure that the structure of the axial-gap rotary electric machine to using soft magnetic material of the present invention describes.The electric rotating machine 10 of axial-gap has and on discoideus parts 21, has configured in a circumferential direction the rotor 50 of multiple permanent magnets 20, configured the stator 60 of multiple stator tooths 30 that comprise iron core 31, the rotating shaft 70 for rotor 50 and stator 60 are configured on concentric circles, the shell 80 of depositing them in a circumferential direction.
Wherein, be not limited to permanent magnet 20, as long as producing the magnet of magnetic force, also can be replaced into other magnets or electromagnet etc.
Stator tooth 30 as shown in Figure 2, is switched on and excitation by the electric wire 33 that its periphery is reeled, make to produce gravitation between permanent magnet 20 and stator tooth 30, by make different stator tooth 30 continuously excitation make to occur rotatablely moving between rotor 50 and stator 60.Because stator 60 is made up of multiple stator tooths 30, so each stator tooth 30 is individually arranged to block iron core 31.
Fig. 2 is the figure of the structure of explanation stator tooth 30.Stator tooth 30 has iron core 31, insulator 32, electric wire 33.Insulator 32 is configured in iron core 31 around in order to ensure iron core 31 with the insulation of electric wire 33, is wound with electric wire 33 around insulator 32.Insulator 32 uses one or more pieces insulating papers or the laminal resin material below thickness 1mm etc., and electric wire 33 uses the cross section taking copper or aluminium etc. as mother metal to be roughly circle or cross section to be roughly the wire rod of rectangle.
Fig. 3 is the figure of the structure of the iron core of explanation stator.Iron core 31 is made up of the laminate structure 1 of the lamellar soft magnetic material taking iron, cobalt or nickel as mother metal, this laminate structure 1 can be by being cut to respectively length L to lamellar soft magnetic material, the material of the rectangular flat plate shape of width B is stacked piecewise arbitrarily, but in the present embodiment, the rectangular flat plate shape thin plate multi-disc with same length L, width B is overlapped to form to the roughly soft magnetic material piece 2 of cuboid, and then make soft magnetic material piece 2 that width B is different number in accordance with regulations stacked and form.
Each rectangular flat plate shape thin plate, in order not make the distortion such as laminal soft magnetic material bends, with cutting machine etc. by every one or more pieces cut-outs, in the situation that multi-disc is cut off simultaneously, in order to make along with the residual stress that is breaking at plane of disruption generation can not impact iron loss, also according to the cutting machine margining tablet number of the thickness of soft magnetic material and use.
Like this, because making iron core 31 is by the laminate structure 1 of soft magnetic material piece 2 stacked formation different width B, so in the time being cut to each rectangular flat plate thin plate, can not make soft magnetic material shifting ground become circular, the cross sectional shape arbitrarily such as polygon or substantially elliptical roughly.
As mentioned above, when iron core 31 is passed the magnetic flux excitation that energising produces to electric wire 33, the vortex flow producing because of the inside of iron core 31 and iron core 31 add the residual stress that the strain that produces man-hour causes etc. to be hindered excitation to produce to lose, the Efficiency Decreasing of electric rotating machine.
For example, as shown in the reference diagram of Fig. 4, in the situation of the iron core 31 that riveted joint is manufactured to lamination, the caulking part of the laminate structure 1 of soft magnetic material produces strain, and loss increases.
On the other hand, as shown in this embodiment, to make in the iron core 31 of soft magnetic material piece 2 stacked acquisitions of the overlapping roughly cuboid forming of rectangular flat plate shape thin plate multi-disc, the strain that while being processed as each rectangular flat plate shape thin plate, the plane of disruption produces is less, so can reduce loss compared with the iron core 31 of manufacturing by riveted joint.
In addition, the riveted joint that has as shown in the reference example of Fig. 4 is used in the iron core of projection, because make soft magnetic material pass through punching processing moulding, so produce more leftover pieces, on the other hand, in iron core of the present invention, make soft magnetic material cut off to be respectively processed as rectangular flat plate shape to carry out moulding, so the generation of leftover pieces is few, the use amount that can expect soft magnetic material is cut down and the cost cutting of parts expense.
In addition, make the stacked direction of soft magnetic material piece 2 be not limited to a direction, as long as shown in this embodiment, it in axial-gap rotary electric machine, is the direction that roughly becomes 90 degree with direction of principal axis, on the other hand, in radial gap type electric rotating machine, be the direction that roughly becomes 90 degree with radial direction, just can change stacked direction.
As an example, in axial-gap rotary electric machine, manufacture cross section and be roughly trapezoidal iron core, can enumerate as shown in Figure 5A with cross section roughly trapezoidal upper base and the vertical direction of going to the bottom, as shown in Figure 5 B with cross section roughly trapezoidal upper base with go to the bottom parallel direction or as shown in Figure 5 C with cross section roughly parallel direction of trapezoidal hypotenuse etc. as stacked direction.
To be explanation arrange the figure of the structure of the stator tooth chamfer shape (R shape) roughly in the bight of iron core for Fig. 6 A and Fig. 6 B.The bight 36 of the iron core 31 shown in Fig. 6 A is acute angle roughly in trapezoidal situation, 36 one-tenth, the bight of iron core 31 than electric wire 33 allow the less acute angle of bending radius time, there is the situation that produces gap between electric wire 33 and insulator 32 and iron core 31.Electric wire 33 can not be in the situation of bight 36 bendings, and iron core 31 because the gap between electric wire 33 and insulator 32 and iron core 31 reduces, may increase loss with respect to the ratio of stator tooth 30 overall volume.
In addition, the insulator 32 that is material in order to insulating paper covers in the situation of iron core 31, because bight 36 is acute angles, so insulator 32 may be damaged.Now, by regulating thickness and the width B of stacked soft magnetic material piece 2, make as shown in Figure 6B bight 36 become roughly chamfer shape ground stacked, alleviate the load to insulator 32 and prevent breakage, and make electric wire 33 along bight 36 bendings, gap between electric wire 33 and insulator 32 and iron core 31 reduces, and can make iron core closely configure, and obtains losing less stator tooth 30.
Fig. 7 is the figure of the structure of the stator tooth in the situation of the explanation thickness that changes soft magnetic material piece 2.The thickness T of soft magnetic material piece 2 can be by different thickness soft magnetic material be cut off, by overlapping soft magnetic material multi-disc cut-out or make to cut off for many times with same widths B after stacked change of material.While making the stacked formation iron core 31 of soft magnetic material piece 2, the thickness T of soft magnetic material piece 2 needs not to be certain.
As an example, be roughly in trapezoidal iron core in cross section, by only making as shown in Figure 7 roughly trapezoidal upper base and going to the bottom near the thinner soft magnetic material piece 2a for thickness T, the roughly chamfer shape in bight 36 and the contact-making surface of insulator 32 that form at the end face of soft magnetic material piece 2 become level and smooth, can alleviate the load to insulator 32, prevent breakage.
In addition, be the thicker soft magnetic material piece 2b of thickness T in addition by making roughly trapezoidal upper base and going to the bottom neighbouring, the soft magnetic material 1 that can prepare a large amount of equal length, width makes soft magnetic material piece 2b moulding, therefore can also shorten manufacturing time.Certainly, while forming each soft magnetic material piece 2, also can make the width B of stacked lamellar soft magnetic material change minutely piecewise, make it form more level and smooth chamfer shape.
[embodiment 2]
Fig. 8 is the figure that explanation is used the structure of the stator tooth of the situation of the insulator that possesses recess.
Insulator 32 is made up of the laminal insulating material below thickness 1mm, by possessing the downside insulator 32a of the recess consistent with the peripheral shape of iron core 31 and the upside insulator 32b of the upper end open sealing of downside insulator 32a being formed.Wherein, downside insulator 32a, upside insulator 32b are all with moulding such as synthetic resin.
Use in the situation of such insulator 32, the soft magnetic material 1 of one or more pieces overlapping rectangular flat plate shapes is cut to the soft magnetic material piece 2 of any width B, recess inside at downside insulator 32a stacks gradually, and the top that covers iron core 31 with upside insulator 32b, now make the back side of upside insulator 32b and the soft magnetic material piece of topmost 2 upper surface close contacts.
