Description

The present invention relates to a power generator in which a magnet (or an electromagnet) and a power generating coil are fixed, and a rotating plate is provided between the two so as to intermittently cut magnetism transmitted to the power generating coil.

In a conventional power generation method, power is generated by exchanging the N-pole and the S-pole of magnetism transmitted to the power generation coil by rotating either the magnet (or electromagnet) or the power generation coil.

BEST MODE FOR CARRYING OUT THE INVENTION

The present invention is directed to a flat plate type in which a plurality of magnetic shield plates made of a material having a magnetic shield effect are radially provided at arbitrary intervals on a rotating plate mounting portion of a rotating shaft that is rotatable, receiving power from the outside. A set-shaped ring-shaped coil in which a plurality of power generating coils are arranged in a ring shape facing the main plane of the rotating plate, and a plate-shaped ring-shaped magnet in which a plurality of N-poles and S-poles are alternately arranged facing the opposite surface, respectively. The flat rotary plate, the flat annular magnet, and the power generating coil are configured to be relatively movable.

In the above configuration, the magnetism exerted on the power generation coil by rotating the rotating plate is bypassed from the N pole to the S pole via the shield plate at a certain portion of the shield plate. As a result, the magnetism exerted on the power generation coil is repeatedly turned on and off so that an electromotive force is generated in the power generation coil. The power generation unit and the rotating unit are cut off and the power generation unit is fixed.

An example of the magnet 2 is shown in FIG. In this case, the shape of the magnet is annular, and one side is fixed to the fixing plate. The magnetic member may be any member such as a ferrite magnet, a rare earth element, and an alnico. In addition, an electromagnet may be used instead of the permanent magnet.

The outer shape of the magnet is not limited to a ring shape, but may be any flat shape such as a rectangle or a polygon. In the case of the annular shape, the annular shape was equally divided to form a magnet in which N poles and S poles were alternately formed.

One example of the power generation coil is shown at 103 in FIG. The coil types are: air-core coil, core coil made of ferromagnetic material with wire wound around it, integrated coil formed by winding several phases around a ring-shaped integral core, and coil formed on the base Any configuration such as a flat coil may be used. The coils are arranged in a ring shape facing the respective poles of the magnet and fixed to the fixing plate.

One example of a rotating plate is shown at 102 in FIG. A magnetic shield plate 1 made of a ferromagnetic material is radially arranged at an arbitrary interval via a magnetic shield plate mounting portion 6 on a rotating shaft 7 which rotates by receiving power from the outside.

The magnetic shield plate is set to have such a size that magnetism flows from the N pole through the inside of the magnetic shield plate to the S pole. By rotating the rotating plate, magnetism bypasses from the N pole to the S pole via the shield plate at the portion with the magnetic shield plate and does not flow to the power generation coil. Flows. As a result, the magnetism on the power generation coil side is repeatedly turned on and off, and an electromotive force is generated in the power generation coil. FIG. 4 shows the flow of magnetism.

The wiring of the generating coil may be any wiring. In addition, a rectifier and electronic components are arranged to extract an electromotive force according to the purpose of use.

When a completely diamagnetic material is used as the material of the magnetic shield plate of the rotating plate of the first embodiment, the magnetism repels the shield plate and flows avoiding the shield plate. Does not flow to the area, but flows in the area without the shield plate. As a result, magnetism is repeatedly turned on and off on the power generation coil side, and an electromotive force is generated. FIG. 5 shows the flow of magnetism.
Since a completely diamagnetic material requires cooling, a cooling device is added to the components.

In the first embodiment, the magnetism applied to the power generation coil is weakened by the thickness of the shield plate of the rotating plate. Therefore, a magnetic relay plate 11 of a size for relaying magnetism made of a ferromagnetic material is added to a gap portion (a portion where magnetism flows through the power generation coil) of the rotating plate without the magnetic shield plate in the first embodiment.
