A magnet disc constituted in a same way is provided in parallel with the former one on the same shaft so as to have their inner polarities repel each other. Rotary brushes, which are made of same material as the magnet segments and turned with the rotations of the magnet segments, are pressed against the circumferential surfaces of the respective magnet segments with proper pressures and arranged so as to have their polarities repel each other both vertically and radially. The respective centers of the magnet segments arranged in parallel with each other are diagonally connected with each other. With such a constitution of a generator, by utilizing magnetic field actions in the magnets, a voltage can be elevated and a counter torque can be reduced.

FIELD OF THE INVENTION The present invention relates to a coilless magnet generator.

[Prior art]

The technology of the present invention is based on a single pole induction generator. Since the conventional single-pole induction generator has a single voltage generation location because it is a single pole, the generated voltage is extremely low, and it is generally unusable for practical use. Further, since many contact brushes are installed around the rotor rotating at high speed, a voltage drop is caused by frictional heat loss, which makes handling difficult.

DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, some embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 shows the power generation principle of a unipolar generator, either metal placed in a unified magnetic field,
When the rotating body, which itself is a conductor magnet, is rotated, a potential difference is generated between the week edge portion and the central portion, and a current flows when connecting with a brush.

With respect to the polarity that appears, when a right rotation is applied when viewed from the N phase, a positive pole appears at the center and a peripheral edge becomes a negative pole, and the polarity that appears at the reverse rotation becomes opposite. In the case of clockwise rotation, when connecting with a brush, current flows from the central portion toward the peripheral portion, as shown in FIG. The magnitude of the voltage is obtained by the product of the square of the radius of the rotating body, the magnetic flux density, and the rotation speed. As an example, a rotating body with a diameter of 200 mm is unified with a magnetic field of 2.2 Tesla, and the generated voltage at the time of 6000 rotation is as low as around 1.5V.

FIG. 2 shows a form of a connecting method which is a feature of the present invention. When the rotor itself is a magnet or two rotors having the same ability are connected with the same poles as shown in FIG. 2 and rotation is given, a potential difference occurs between the shafts and a current flows when they are connected. The generated voltage at this point is a combination of the generated voltages of both rotors. The principle of this power generation is based on the Lorentz force. The solid arrows in the figure indicate the flow of current and the dotted arrows indicate the direction in which the Lorentz force acts.

FIG. 3 shows one form of a method of connecting the rotating brushes, which is a feature of the above embodiment. In the case where the magnets are arranged side by side on the same axis, the current is circulated as shown in FIG. 3 by configuring the inner polarity of the magnets to be arranged so as to repel each other. As for the voltage between the brushes at this point, a value obtained by combining the voltages of the two rotors is observed as in the above.

In the connection method of the embodiment shown in FIG. 2, the repulsive force which is a problem when connecting the same poles does not cause the magnetic repulsive force by efficiently designing and implementing the magnetic circuit described in the above means. Can be reduced to a level. Another role of the magnetic circuit is to prevent demagnetization because the magnetic flux density is high when the magnet used is an alnico magnet but the holding force is low.

FIG. 4 of the above embodiment is a diagram in which a power source is applied between the brushes of FIG. 2, and when two currents are passed, the two rotors are
It rotates in the direction of the arrow in the figure. At the time when this monopolar induction was discovered, it was used as a monopolar motor, but there was no such connection method. When connected by this method, the rotating torque is doubled as compared with the case of a single pole.

The generation of this rotational force is due to the Lorentz force, which is the basis of electromagnetic theory. When a current is applied to the movable electric wire placed in the magnetic field of the N pole from the front to the front, the electric wire receives the force in the right direction and moves to the right direction.

Looking at the action of the Lorentz force in the connection method of FIG. 4 of the above embodiment, the current flows from the right rotor shaft through the rotor body toward the contacts. Since the material of this rotor is a metal magnet or a conductor provided with its ability, a magnetic field exists also in the rotor.

When the electric current moves through the magnetic field existing in the rotor, the lines of magnetic force are emitted from the bottom to the top, that is, when viewed from the N-pole surface like the rotor on the right side of FIG. When electrons move from the central axis to the contact,
The mobile electrons move while changing their directions to the right by 90 degrees with respect to the traveling direction.

As described above, if an electric wire is in a magnetic field, it will move to the right by a force, but the electric current that moves in the rotor is fixed because the outlet of the electric current is fixed at the contact point of the two rotors. I can't move like. The electrons that move while changing their directions to the right by 90 ° have an action of repulsively moving the magnetic field itself to the right, instead of being unable to move themselves, and become a Lorentz force that rotates the rotor to the right.

In the above embodiment, the electric current that has entered the rotor on the left side from the rotor on the right side in FIG. 4 through the contact point of the rotor turns to the left when the rotation of the rotor is viewed from the N-pole surface. Therefore, the two rotors flow toward the center, and the two rotors are electrically connected.

Solid arrows in the rotor of FIG. 4 indicate the flow of electric current, and dotted arrows indicate the direction in which the Lorentz force acts. By this action, the two rotors in contact with each other in FIG. 4 rotate in the direction of the peripheral arrow in the drawing when a current is applied.

FIG. 2 is based on the Lorentz force in the same direction both in the power generation principle of the above embodiment and in the rotation principle described in FIG. 4, and the action of the Lorentz force acting in the same direction is the effect of the present invention. This is the greatest feature. Due to this action, the coilless magnet generator of the present invention can slightly suppress the reverse torque of the action reaction, which acts on the existing generator.

FIG. 5 is a diagram showing the flow of current at the time of power generation of a generator configured by applying the power generation principle of the above-described embodiment and each rotor connection method. 1 in the figure
Only the portion of is a non-conductive shaft, and the electric current can be taken out from the center portion on both outer sides of the rotating brush with a contact brush (2 in the figure) or the like.

FIGS. 6 and 7 show a split magnet and a rotating brush, which are the main parts of the present invention, and are made of a thin plate of alnico magnet.
Layer as shown in the figure using insulating material such as glue. When a current flows through each of the divided conductors and the rotating brush, the stratification reduces eddy currents around the current and reduces the induction of an action that hinders the rotation of the rotor or the brush.

In FIG. 8, the split magnets of the above embodiment are used as a rotating body, and each split magnet is insulated so that it can endure high speed rotation. Since the peripheral surface of the rotating body is the contact surface of the rotating brush, the metal surface is exposed and is smoothly polished.

FIG. 9 of the above-described embodiment shows an armature of the generator of the present invention, and the polarities of the rotating magnets, which are arranged around the divided magnets and the peripheral surfaces thereof, are repelled by the inner magnetic poles. To configure.

The connection of the armature connects the central portions of the split magnets, which are diagonal to each other. The rotating brushes are made by connecting the rotating brushes facing each other with a good conductor axis, and by joining a nonconductive axis (1 in the figure) at any one point, and contacting them from the center parts on both outer sides. Take out the current with a brush.

FIG. 10 shows the armature of the above-described embodiment in which a magnetic circuit (9 in the figure), an outer frame and a bearing, and a rotating brush pressing mechanism are configured.

It is to be noted that the diameter of the rotating magnet is 50 mm to 60 m when the diameter of the divided magnet rotating body of the above embodiment is 200 mm.
When rotation is given by an external power as m, a voltage of about 13 to 15 V is observed around 5000 rotations.

The electric current is determined by the height of the stratification of each split magnet and the rotating brush. Heat naturally occurs when an electric current flows, and in general, it flows in a magnet that is weak to heat, but in the case of an alnico magnet, it has a strong property against heat,
Since it has a durability of 400 degrees or more, it is a perfect material for the generator of the above embodiment.

The generator of the above embodiment also has a function as an electric motor, and a large amount of electric power or power can be obtained by connecting several units in parallel on the shaft. In that case, the external power input to the generator is less than half of the conventional one.

Since each of the above-described embodiments is disclosed as an example, the present invention is not limited to these embodiments, and within the scope of technical matters described in claims when carrying out the invention. Needless to say, it can be implemented by changing or modifying the situation.

[0032]

As described above, according to the present invention, it is not the power generation method of inducing an electromotive force by moving a coil in a magnetic field line, which is often found in existing power generators, but in the magnet itself. By utilizing the magnetic field in the above, it is possible to supply an efficient generator that suppresses the reverse torque of the action and reaction to a slight degree and that generates a constant DC current that does not require rectification.
