DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generator, and more particularly, to a power generating device, in which a plurality of electromagnets are arranged in a ring, and an arc-shaped protruding portion facing each electromagnet is provided in the electromagnet. A rotor made of a magnetic material having a permanent magnet attached to each of the bases is disposed, and a current is sequentially passed through the juxtaposed electromagnets to rotate the rotor, thereby providing the rotor at the center of the rotor. The present invention relates to a power generating device for giving a rotational motion to a power shaft.

[0002]

2. Description of the Related Art Conventionally, as a power generating device for obtaining power from electric energy, a rotating electromagnet is rotated by a mutual attractive force of an annular fixed electromagnet and a rotating electromagnet supported at the center thereof, and the rotating force is taken out as power. There is a so-called electric motor.

[0003] However, in such a conventional motor, both the fixed side and the rotating side are electromagnets, and use only electric energy. For this reason, the output does not increase in spite of using power, and improvement in this point has been desired.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has been made in view of the above. By using both the electric energy of an electromagnet and the magnetic energy of a permanent magnet, a large output with a small electric power is obtained. In addition, at the moment when the attracting motion occurs between the newly energized electromagnet and the rotor, the force relationship due to the attraction to the electromagnet whose energization has been stopped is cancelled. And a power generation device capable of smoothly rotating the power generation device.

[0005]

SUMMARY OF THE INVENTION Accordingly, the gist of the present invention is to provide a plurality of electromagnets arranged in a ring, a current switching circuit for sequentially passing a current to each of the arranged electromagnets, A rotor made of a magnetic material disposed in an annularly arranged electromagnet, provided with arc-shaped protrusions facing each of the electromagnets, and having permanent magnets attached to respective bases of the protrusions; And a power shaft provided at the center of the magnetic body.
The protrusion in the circumferential direction has a length in the circumferential direction of the electromagnet.
Than the length will be formed to be large, thereby when excited the electromagnet located in front of the rotational direction of the rotor, said circular on the side facing to the energized electromagnets of the magnetic The magnetic flux passing through the arc-shaped protrusion converges within a range that substantially linearly connects the excited electromagnet and the permanent magnet, and faces a non-excited electromagnet located behind the excited electromagnet in the rotational direction. The magnetic power generation device is characterized in that the magnetic portion becomes a magnetic flux blank region, and the converged magnetic flux applies a rotational torque to the power shaft.

[0006]

Next, the operation of the present invention will be described. In the present invention, the magnetic force of the permanent magnet is generated by making the rotor, which is a magnetic material, magnetically permeable. Then, in a state in which current is not supplied to any of the ring-shaped electromagnets, the electromagnets to which the protruding portions of the rotor are approaching are in the magnetic field of the permanent magnets as simple magnetic bodies.

Therefore, when an electric current is supplied to the electromagnet next to the electromagnet to which the protruding portion of the rotor approaches , the magnetic flux from the permanent magnet is generated.
Is the range that is almost linearly connected to the energized electromagnet instantaneously.
Converged within the enclosure to form a magnetic domain. As a result, the protrusion of the rotor is strongly attracted to the electromagnet, and the rotor rotates. At this time, the direction of rotation of the converged magnetic flux of the rotor protrusion is
There is a gap of magnetic flux behind and behind, so
Between the non-excited electromagnet and rotor adjacent to the
Does not interact. In other words, the rotor
Reduces the attractive force in the direction that hinders rotation by a non-excited electromagnet.
I will not receive it. When the rotor is further rotated, the width of the magnetic domain portion of the protrusion of the rotor gradually increases, and the attraction force further increases.

However, unless the input is continued to the electromagnet and the input is not switched to the next electromagnet, when the central portion of the protruding portion of the rotor reaches the center of the input electromagnet, the electromagnet and the permanent magnet are connected to each other. Although the mutual attraction force is maximized, the rotor stops at the same time because the attractive force acting in the rotation direction becomes close to zero.

Therefore, when the end of the protruding portion of the rotor approaches the adjacent electromagnet, the input is made to the adjacent electromagnet,
On the other hand, at the same time, the input of the electromagnet which has been input is stopped. By continuously performing this motion, the rotor rotates. Then, the rotation is performed smoothly, and a strong rotating force can be generated with a small amount of electric power by a strong attraction effect by the magnetic force of the permanent magnet and the magnetic force of the electromagnet. And the rotational force of this rotor is taken out as an output from a power shaft.
