Description

  The present invention relates to a fixed permanent magnet generator using the magnetic energy of a permanent magnet.

Conventional generators, whether small or large, basically consist of a rotating armature for power generation and a stator for excitation. In order to generate electric power, the armature must be rotated. The energy required to rotate this armature must be supplied from the outside with strong energy in proportion to the generated electric power.
The present invention provides a fixed permanent magnet generator using a completely different method from the conventional mechanism that makes the best use of the magnetic energy of the permanent magnet.

  In order to solve the above problems, the present invention is different from the conventional system in that it has a simple structure without an armature and an excitation stator for generating electricity, and does not require strong external energy. It is an issue to provide.

Means to be Solved by the Invention

  In order to solve the above problems, the present invention, as shown in FIG. 1, attracts the opposing yoke fixed to the nonmagnetic alloy case (not shown) and the N pole of the permanent magnet to the upper part and the S pole to the lower part. It is embedded and fixed in the groove to maximize the force.

  Inside the above-mentioned counter-type yoke, a power generation coil wound around an iron core in a concentrated manner is fixed integrally with the yoke. In this case, between the north and south poles of the permanent magnet and the power generation coil. A space is formed between the upper and lower magnetic shielding disks, the opposing yoke and the power generation coil are used as one unit, and a plurality of units are arranged and fixed in an annular form. FIG. The

  By using a high-permeability magnetic alloy permalloy for the iron core of the above power generating coil, the leakage flux is reduced and a strong current can be obtained.

The above-mentioned two upper and lower magnetic shielding disks are made of a diamagnetic material and a non-magnetic metal alloy and processed into a laminated disk with a sandwich structure of a plurality of ultrathin plates.
The non-permeability is very low, the magnetic flux density in the coil unit for power generation is about 300 millitesla, and the value is set to about several tens of millitesla, which minimizes the eddy current of the magnetic shielding disk. It can be suppressed.
This magnetic shielding disk is naturally not affected by the magnetism of the permanent magnet and can be rotated by a small force motor (not shown in the drawing).

The two magnetic shielding disks are provided with an opening having an elliptical diameter at the same position on the upper N pole side and the lower S pole side of the power generating coil unit.
This opening is for the magnetic circuit where the magnetic flux pulls out the coil and is one of the important functions of the fixed permanent magnet generator

  With the configuration of each device described above, the magnetic shielding disk, which is the main focus of the fixed permanent magnet generator of the present invention, is rotated at high speed, so that the magnetic flux from the N pole to the S pole can be opened and shielded simultaneously. As a result, a temporal change occurs in the magnetic flux that pulls out the coil, and DC power is generated by the law of electromagnetic induction. This can solve the problem.

Effect of the invention

Conventional generators require powerful energy comparable to the amount of power generated in order to generate electricity. The fixed permanent magnet generator according to the present invention has no correlation between the external energy for generating power and the amount of generated power, and is a magnetic shielding disk fixed to a rotating shaft of a nonmagnetic alloy in a plurality of coil units for power generation. Is rotated at high speed by a small motor (not shown in the figure), so that DC power can be generated by the law of electromagnetic induction.
The generator coil units of the generator are connected in parallel, and a part of the generated power can be fed back to a small battery (not shown in the figure) and used for operation.
In the application form, there are 4 coil units for power generation.
The fixed permanent magnet generator of the present invention can be used for the power supply of various electric devices such as a simple structure, environmental friendliness, low driving noise, and good cost performance.
