Description of Embodiments
Hereinafter, best modes for carrying out the invention will be described based on FIGS. 1 to 9.
As a basic configuration of a power generator according to the présent invention, as shown in FIGS. 1 and 5, a first permanent magnet member 1 provided with permanent magnets M1 arranged in a tubular or annularform, a second permanent magnet member 2 provided with permanent magnets M2 arranged in a tubular or annular form, and an electromotive coil member 3 provided with electromotive coils C arranged in a tubular or annular form are arranged concentrically to hâve a telescoping structure. By virtue of relative rotation between the first permanent magnet member 1 or/and the second permanent magnet member 2 and the electromotive coil member 3, power génération in the electromotive coil member 3 is induced.
As a configuration common to examples 1 to 3, as shown in FIGS. 2 and 6, the first permanent magnet member 1 is constituted of a large number of permanent magnets M1 whose polarities are opposite to each other in the radial direction, that is, a large number of the permanent magnets M1 with opposite polarities on the outer peripheral surface and the inner peripheral surface which are arranged in the circumferential direction.
Similarly, the second permanent magnet member 2 is constituted of a large number of permanent magnets M2 whose polarities are opposite to each other in the radial direction, that is, a large number of the permanent magnets M2 with opposite polarities on the outer peripheral surface and the inner peripheral surface which are arranged in the circumferential direction.
The number of either of the permanent magnets M1 and the permanent magnets M2 is preferably an intégral multiple of the number of the other permanent magnets. In the examples 1 to 3 to be described later, the number of the permanent magnets M2 is doubled the number of the permanent magnets M1.
As shown in FIGS. 2 and 6, a large number of the permanent magnets M1 are arranged adjacent to each other so that their polarities are opposite to each other. For example, the polarity of the outer peripheral surface of the permanent magnet M1 adjacent to the permanent magnet M1 whose polarity on the outer peripheral surface is N pôle (the polarity on the inner peripheral surface is S pôle) is S pôle (the polarity on the inner peripheral surface is N pôle).
Similarly, a large number of the permanent magnets M2 are arranged adjacent to each other so that their polarities are opposite to each other. For example, the polarity on the outer peripheral surface of the permanent magnet M2 adjacent to the permanent magnet M2 whose polarity on the outer peripheral surface is N pôle (the polarity on the inner peripheral surface is S pôle) is S pôle (the polarity of the inner peripheral surface is N pôle).
In the formation of the first permanent magnet member 1, the permanent magnets M1 constituted of magnetic shells having a circular-arc cross section are assembled in a tubular or annular form. Alternatively, the permanent magnets M1 magnetizes a tubular or rod-like magnetic body so as to hâve the above polarity arrangement, whereby the first permanent magnet member 1 is formed.
The magnetizing is performed in a straight form along a central axis direction of the magnetic body or is performed on a skew with an inclination angle in a coaxial direction.
Further, in the présent invention, the permanent magnets M1 may be buried in a peripheral surface of a rotation shaft 4 or a fixing shaft 4‘ to be described later, and be arranged in a tubular or annular form, thereby forming the first permanent magnet member 1.
In the formation of the second permanent magnet member 2, the permanent magnets M2 constituted of magnetic shells having a circular-arc cross section are assembled in a tubular or annular form. Alternatively, the permanent magnets M2 magnetizes a tubular magnetic body so as to hâve the above polarity arrangement, whereby the second permanent magnet member 2 is formed. The magnetizing is also performed in a straight form along a central axial direction of the magnetic body or is performed on a skew with an inclination angle in a coaxial direction. The second permanent magnet member 2 has a larger diameter than the first permanent magnet member 1 and is disposed concentrically outward the first permanent magnet member 1.
As shown by dashed lines in FIG. 1, the présent invention includes a case where the first permanent magnet member 1 has stages 1Aand 1B and the second permanent magnet member 2 has stages
2A and 2B, as well as a case where each segment (1A and 1B or 2A and 2B) is a single member.
The electromotive coil member 3 is constituted of a large number of eiectromotive coils C arranged in the circumferential direction and is arranged concentrically with the first and second permanent magnet members 1 and 2. For example, the electromotive coil member 3 is disposed concentrically outward the first and second permanent magnet members 1 and 2 as shown in the example 1 to be described later, or the electromotive coil member 3 is disposed concentrically between the first permanent magnet member 1 and the second permanent magnet member 2 as shown in the examples 2 and 3 to be described later.
In the power generator according to the présent invention, as shown in FIGS. 4 and 9, the first permanent magnet member 1 and the second permanent magnet member 2 cooperate with each other to change the magnetic force, whereby efficient power génération can be induced.
Namely, when the polarity of the outer peripheral surface of the permanent magnet M1 of the first permanent magnet member 1 is opposite to the polarity of the inner peripheral surface of the permanent magnet M2 of the second permanent magnet member 2 facing the permanent magnet
M1 in the radial direction, strong stable magnetic force is generated between them.
For example, when the polarity of the outer peripheral surface of the permanent magnet M1 is N pôle, and the polarity of the inner peripheral surface of the permanent magnet M2 is S pôle, as shown by F1 in the drawing, stable magnetic force flowing from the permanent magnet M1 to the permanent magnet M2 is generated. Meanwhile, when the polarity of the outer peripheral surface of the permanent magnet M1 is S pôle, and the polarity of the inner peripheral surface of the permanent magnet M2 is N pôle, as shown by F2 in the drawing, stable magnetic force flowing from the permanent magnet M2 to the permanent magnet M1 is generated.
When the polarity of the outer peripheral surface of the permanent magnet M1 of the first permanent magnet member 1 is the same as the polarity of the inner peripheral surface of the permanent magnet M2 of the second permanent magnet member 2 facing the permanent magnet M1 in the radial direction, the magnetic force flowing between them is not generated and the magnetic forces 10 in directions shown by F3 and F4 in the drawing are generated.
Namely, as shown by F3 in the drawing, the magnetic force flowing from the outer peripheral surface of the N pôle of the permanent magnet M1 to the outer peripheral surface of the S pôle of the adjacent permanent magnet M1 is generated. Moreover, as shown by F4, the magnetic force flowing from the outer peripheral surface of the N pôle of the permanent magnet M2 to the outer peripheral surface of the S pôle of the adjacent permanent magnet M2 is generated.
By virtue of the relative rotation between the first permanent magnet member 1 or/and the second permanent magnet member 2 and the electromotive coil member 3, the magnetic forces in the directions shown by F1 to F4 in the drawing are replaced and act on the electromotive coils C, whereby efficient power génération can be obtained.
In the first and second permanent magnet members 1 and 2 according to the présent invention, the thickness, the magnetic force, and the number of the permanent magnets M1 and M2 can be set freely, so that the magnetic force change can be improved.
Although the permanent magnets M1 and M2 of the first and second permanent magnet members 1 and 2 are arranged adjacent to each other in a tubular form as shown in the drawing, they may be arranged at a distance in the circumferential direction.
Example 1
In the example 1, as shown ïn FIGS. 1 to 4, a first tubular yoke 5 is fitted onto a rotation shaft 4 10 rotated .by a power source 9 such as a motor, a turbine, and an engine, and the first permanent magnet member 1 is fitted onto the first tubular yoke 5.
The second permanent magnet member 2 is disposed concentrically at a distance in the radial direction from the first permanent magnet member 1. The electromotive coil member 3 is fitted onto the second permanent magnet member 2, and a second tubular yoke 6 is filter onto the 15 electromotive coil member 3.
Accordingly, in this example, the first permanent magnet member 1, the second permanent magnet member 2, and the electromotive coil member 3 arranged concentrically to hâve a telescoping structure are provided. The first permanent magnet member 1 is rotated to fix the second permanent magnet member 2 and the electromotive coil member 3, and the first permanent magnet member 1, the second permanent magnet member 2, and the electromotive coil member 3 are relatively rotated. The power génération in the electromotive coil member 3 is induced by the relative rotation.
As shown in FIG. 2, the electromotive coil C of the electromotive coil member 3 is formed by winding winding wires 8 around a plurality of cores 7 arranged on the inner peripheral surface of the second tubular yoke 6 at a distance in the circumferential direction. Each of the cores 7 is formed by stacking silicon steel plates and adhered to the outer peripheral surface of each of the permanent magnets M2 of the second permanent magnet member 2.
The number of the permanent magnets M2 of the second permanent magnet member 2 is doubled the number of the permanent magnets M1 of the first permanent magnet member 1, and the permanent magnets M1 and M2 are faced in the radial direction. Namely, the outer peripheral surface of the one permanent magnet faces the inner peripheral surfaces of the two permanent 15 magnets M2.
As described above, since the permanent magnets M2 are arranged adjacent to each other so that their polarities are opposite to each other, the permanent magnet M2 having the inner peripheral surface of the same polarity (for example, N pôle) as the polarity (N pôle) of the outer peripheral surface of the permanent magnet M1 and the permanent magnet M2 having the inner peripheral surface of the opposite polarity (S pôle) face the outer peripheral surface of the one permanent magnet M1, so that the magnetic force change to be described later occurs frequently, whereby efficient power génération can be obtained.
To describe in detail, as shown in FIG. 4, when the polarity of the outer peripheral surface of the permanent magnet M1 is opposite to the polarity of the inner peripheral surface of the permanent magnet M2 facing the permanent magnet M1, strong stable magnetic force is generated between them in a direction shown by F1 or F2.
Accordingly, the first permanent magnet member 1 rotâtes to rotate each of the permanent magnets 10 M1, whereby the magnetic force in the direction shown by F1 and the magnetic force in the direction shown by F2 alternately act on the electromotive coil C through the core 7 adhered to the outer peripheral surface of each of the permanent magnets M2 to change the magnetic force in the electromotive coil C, and, thus, to induce efficient power génération.
As shown in FIG. 4, when the polarity of the outer peripheral surface of the permanent magnet M1 is the same as the polarity of the inner peripheral surface of the permanent magnet M2 facing the permanent magnet M1, the magnetic force does not flow between them, and the magnetic force is generated in the directions shown by F3 and F4 in the drawing. A portion of the magnetic force in the direction shown by F4 is added to the magnetic force in the direction shown by F1, whereby the magnetic force change is compensated.
It is préférable that the facing interval between the permanent magnet M1 of the first permanent magnet member 1 and the permanent magnet M2 of the second permanent magnet member 2 is reduced as far as possible to flow the magnetic force effectively.
Example 2
In the example 2, as shown in FIGS. 5 to 7 and 9, a first tubular yoke 5 is fitted onto a fixing shaft 4', and the first permanent magnet member 1 is fitted onto the first tubular yoke 5.
The electromotive coil member 3 is rotatably disposed coaxially at a distance in the radial direction from the first permanent magnet member 1, and the second permanent magnet member 2 is fixed 10 and coaxially disposed at a distance in the radial direction from the electromotive coil member 3. A second tubular yoke 6 is fitted onto the second permanent magnet member 2. The electromotive coil member 3 is rotated by a power source 9 such as a motor, a turbine, and an engine.
Accordingly, in this example, the first permanent magnet member 1, the second permanent magnet member 2, and the electromotive coil member 3 arranged concentrically to hâve a telescoping structure are provided. The electromotive coil member 3 is rotated to fix the first and second permanent magnet members 1 and 2, and the electromotive coil member 3 and the first and second permanent magnet members 1 and 2 are relatively rotated. The power génération in the electromotive coil member 3 is induced by the relative rotation.
As shown in FIGS. 5 and 6, the electromotive coil member 3 is coreless and is provided with an electromotive coil C constituted of an air core coil around which a winding wire 8 is wound in a tubular or annular form, and the electromotive coils C are connected in a tubular or annular form to form the electromotive coil member 3. Alternatively, each of the electromotive coils C constituted of the air core coil is held from the inside and the outside between two tubular bodies constituted of a nonmagnetic body such as glass to form the electromotive coil member 3.
In this example, as in the example 1, the electromotive coil C may be a core coil.
The number of the permanent magnets M2 of the second permanent magnet member 2 is doubled 10 the number of the permanent magnets M1 of the first permanent magnet member 1, and the permanent magnets M1 and M2 are faced in the radial direction. Namely, the outer peripheral surface of the one permanent magnet M1 and the inner peripheral surfaces of the two permanent magnets M2 are faced each other, and the electromotive coil C is interposed in the facing interval.
As described above, since the permanent magnets M2 are arranged adjacent to each other to hâve the polarities be opposite to each other, the permanent magnet M2 having the inner peripheral surface of the same polarity (for example, N pôle) as the polarity (N pôle) of the outer peripheral surface of the permanent magnet M1 and the permanent magnet M2 having the inner peripheral surface of the opposite polarity (S pôle) face the outer peripheral surface of the one permanent .

magnet M1, so that the magnetic change to be described later occurs frequently, whereby efficient power génération can be achieved.
To describe in detail, as shown in FIG. 9, when the polarity of the outer peripheral surface of the permanent magnet M1 is opposite to the polarity of the inner peripheral surface of the permanent 5 magnet M2 facing the permanent magnet M1, strong stable magnetic force is generated between them in a direction shown by F1 or F2 in the drawing.
As shown in FIG. 9, when the polarity of the outer peripheral surface of the permanent magnet M1 is the same as the polarity of the inner peripheral surface of the permanent magnet M2, the magnetic force does not flow between them, and the magnetic forces are generated in the directions shown by 10 F3 and F4 in the drawing.
In this example, the magnetic forces in the directions shown by F1 to F4 in FIG. 9 are directly acted on the inside of the electromotive coil C to induce efficient power génération.
Specifically, the electromotive coil member 3 rotâtes between the permanent magnet M1 of the first permanent magnet member 1 and the permanent magnet M2 of the second permanent magnet member 2, and the magnetic force changes in the directions shown by F1 to F4 in FIG. 9, whereby efficient power génération is induced.
In this example, the electromotive coil C is interposed in the facing interval between the permanent magnet M1 and the permanent magnet M2, so that the facing interval increases. Therefore, it is désirable to efficiently utilize the magnetic forces derived from the permanent magnets M1 and M2 either by increasing to some extent the magnetic forces derived from the permanent magnets M1 and M2 or by using under cryogénie conditions near absolute zéro at which a superconducting phenomenon occurs.
Example 3
In the example 3, as shown in FIGS. 5, 6, 8, and 9, a first tubule yoke 5 is fitted onto a rotation shaft rotated by a power source 9 such as a motor, a turbine, and an engine, and the first permanent magnet member 1 is fitted onto the first tubule yoke 5.
The electromotive coil member 3 is fixed and concentrically disposed at a distance in the radial direction from the first permanent magnet member 1, the second permanent magnet member 2 is rotatably disposed concentrically at a distance in the radial direction from the electromotive coil member 3, and a second tubular yoke 6 is fitted onto the second permanent magnet member 2. The second permanent magnet member 2 is rotated by a power source 10 such as a motor, a turbine, and an engine. The power source 9 and the power source 10 may be the same power source.
Accordingly, in this example, the first permanent magnet member 1, the second permanent magnet member 2, and the electromotive coil member 3 arranged concentrically to hâve a telescoping

structure are provided. The electromotive coil member 3 is fixed to rotate the first and second permanent magnet members 1 and 2, and the electromotive coil member 3 and the first and second permanent magnet members 1 and 2 are relatively rotated. The power génération in the electromotive coil member 3 is induced by the relative rotation.
As shown in FIGS. 5 and 6, the electromotive coil member 3 is coreless and is provided with an electromotive coil C constituted of an air core coil around which a winding wire 8 is wound in a tubular or annular form, and the electromotive coils C are connected in a tubular or annular form to form the electromotive coil member 3. Alternatively, each of the electromotive coils C constituted of the air core coil is held from the inside and the outside between two tubular bodies constituted of a nonmagnetic body such as glass to form the electromotive coil member 3.
In this example, as in the example 1, the electromotive coil C may be a core coil.
The number of the permanent magnets M2 of the second permanent magnet member 2 is doubled the number of the permanent magnets M1 of the first permanent magnet member 1, and the permanent magnets M1 and M2 are faced in the radial direction. Namely, the outer peripheral surface of the one permanent magnet M1 and the ïnner peripheral surfaces of the two permanent magnets M2 are faced each other, and the electromotive coil C is interposed in the facing interval.
As described above, since the permanent magnets M2 are arranged adjacent to each other so that their polarities are opposite to each other, the permanent magnet M2 having the inner peripheral surfaces of the same polarity (for example, N pôle) as the polarity (N pôle) of the outer peripheral surface of the permanent magnet M1 and the permanent magnet M2 having the inner peripheral surface of the opposite polarity (S pôle) face the outer peripheral surface of the one permanent magnet M1, so that the magnetic change to be described later occurs frequently, whereby efficient power génération can be achieved.
To describe in detail, as shown in FIG. 9, when the polarity of the outer peripheral surface of the permanent magnet M1 is opposite to the polarity of the inner peripheral surface of the permanent magnet M2 facing the permanent magnet M1, strong stable magnetic force is generated between them in a direction shown by F1 or F2 in the drawing.
As shown in FIG. 9, when the polarity of the outer peripheral surface of the permanent magnet M1 is the same as the polarity of the inner peripheral surface of the permanent magnet M2 facing the permanent magnet M1, the magnetic force does not flow between them, and the magnetic forces are generated in the directions shown by F3 and F4 in the drawing.
In this example, the magnetic forces in the directions shown by F1 to F4 in FIG. 9 are directly acted on the inside of the electromotive coil C to induce efficient power génération.
Specifically, the first permanent magnet member 1 and the second permanent magnet member 2 rotate while holding the electromotive coil member 3 between them, and the magnetic force changes in the directions shown by F1 to F4 in FIG. 9 in each of the electromotive coils C between the permanent magnet M1 and the permanent magnet M2, whereby efficient power génération is induced.
In this example, the first and second permanent magnet members 1 and 2 may be rotated at the same speed in the same direction, or one permanent magnet member and the other permanent magnet member may be rotated at different speeds in the same direction.
Alternatively, one of the first and second permanent magnet members 1 and 2 is positively rotated and the other is reversely rotated, and their rotation speeds are substantially increased, whereby the power génération efficiency can be improved.
In this example, the electromotive coil C is interposed in the facing interval between the permanent magnets M1 and M2, so that the facing interval increases. Therefore, it is désirable to efficiently utilize the magnetic forces derived from the permanent magnets M1 and M2 either by increasing to some extent the magnetic forces derived from the permanent magnets M1 and M2 or by using under cryogénie conditions near absolute zéro at which a superconducting phenomenon occurs.
