Abstract

The technology starts with the fact that in a conventional power generation method, by eliminating an iron core of an opposite side, first, attraction which attracts each other by magnetic force is not generated. To this end, first, an excitation coil wound on a non-ferrous or plastic bobbin which does not generate an inductive magnetic field due to a magnetic field of one permanent magnet is arranged radially, and the permanent magnet rotating adjacent to an outer side of the core wound with the excitation coil is arranged. The permanent magnet coincides with an outer peripheral surface of the coil-wound core, is radially fixed to the same rotating shaft, and rotates by a motor. The inductive magnetic field is not generated by driving of a rotating body to have no binding force by magnetic flux, thereby operating a generator with relatively small force.

Description

Non-magnetic core generation method {Non-magnetic core generation method}

This technology is a technical field related to the core, which is the main component of a generator for generating electricity.

As the background technology of the invention, all generators require many energy sources for power generation.

This is because many magnets in the generator need a force to rotate with a greater force than they attract each other.

Currently, in all kinds of generators, the rotor with magnetic flux and the core as the stator rotate with different polarities. The power generation efficiency is better as the rotor and stator have different polarities, and the greater the magnetic flux between the relative polarities and the narrower the gap between the polarities.

This is a fundamental problem of the generator.

The law of electromagnetic induction is that when the magnetic field changes, it induces a current in the adjacent conductor.

The induced voltage that occurs together increases in proportion to the number of turns around the coil.

A generator is a device that generates electric current by continuously changing a magnetic field.

Currently, in all kinds of generators and motors, the core, which is a rotor and a stator with magnetic flux, rotates with different polarities. The rotor and stator have magnetic fluxes of different polarities, and the smaller the gap between the counter magnets, the greater the amount of power generated.

However, the larger the magnetic flux and the narrower the gap, the greater the force to attract the magnetic flux in direct proportion, so it must be returned with a larger force.

In this technology, it is intended to realize a generator that eliminates the attraction of magnets that are indispensable to the existing generators.

This application technology to solve this,

It is intended to present a generator core that does not generate any attraction (cogging) due to the magnetic flux generated by the counter magnet by removing the counter magnet and using the magnet only for the rotor.

In a generator that generates electricity induced in a coil by using a plurality of magnets that rotate in an axis adjacent to a core wound around a wire,

In order to exclude the cogging phenomenon instead of the iron core, the coil is wound around a non-ferrous or plastic core that does not generate an induced magnetic force.

A non-magnetic core power generation method that obtains induced electromotive force by rotating the poles of a number of permanent magnets arranged therein in a direction perpendicular to the direction of the rotation axis of the coil.

The expected effect as a generator of the applied technology is

Since there is almost no binding force by magnetic flux that hinders the rotation of the power generation core, the generator can be turned with a small force, so eco-friendly power generation can be achieved very economically.

Figure 4: A perspective view of an excitation coil according to the present technology

All current generators form an inductive magnetic field in the iron core of the other side by the magnetic force of one (mainly a rotor) magnet, and the induced electromotive force is generated by an electromagnetic induction phenomenon in which current is induced in the coil winding this core in the same direction. You will develop.

At this time, a load (cogging phenomenon) that attenuates the rotational force due to the force attracted by the magnets is generated by the magnetic flux generated in the iron core. However, as the load increases, the amount of power generated increases, but relatively more energy is required.

The ratio of the input energy and the amount of power generated is the power generation efficiency of the generator. External energy is consumed by the amount of pulling force of different polarities existing between the iron core and the magnet rotating in a right angle direction.

Since the principle of the existing generator and related sciences and technologies are already widely known, a more detailed description will be omitted.

This technology

By eliminating the iron core core of the opposite side, it starts with the fact that there is no attraction at all to attract each other by magnetic force.

To this end, first, an excitation coil (3-1) wound around a non-ferrous or plastic bobbin that does not generate an induced magnetic field due to the magnetic field of one permanent magnet (4-1) is radially arranged.

A rotating permanent magnet (4-1) is arranged adjacent to the outside of the core wound around the excitation coil.

This permanent magnet (4-1) is radially fixed to the same rotating shaft by matching the outer peripheral surface of the coil wound core, and rotated by the motor (7).

Since there is no induced magnetic field in the driving of this rotating body, there is no binding force by the magnetic flux, so the generator can be turned with a relatively small force.

If this method is described in more detail by the drawings

The important parts applied in this technology are divided into permanent magnet (4-1) and non-magnetic excitation coil (3-1), and the characteristics of each configuration are summarized as follows.

One. The permanent magnet (4-1) is based on a neodymium magnet whose shape is relatively free.

The applied neodymium magnet has a thin plate shape, and the wide sides of the plate have N and S polarities, respectively, and the polarities are alternately arranged between adjacent magnets when installed.

2. The excitation coil (3-1) is composed of non-ferrous or plastic such as aluminum, in which the bobbin winding the coil wire is not magnetic. In addition, all parts, such as the coil fixing frame (3) that radially fixes the excitation coil (3-1), and the fixing brackets and bolts, are composed only of non-ferrous metal.

First of all, the stator group (F)

An insertion groove of the bearing (2) is prepared in the stator base (1), the excitation coils (3-1) radially fixed to the coil fixing frame (3) and the stator lid (5) into which the upper bearing (2) is inserted It is composed of the rotating shaft (6).

Also, the rotor group (R)

On the rotating shaft 6, the permanent magnets 4-1 are radially fixed to the permanent magnet fixing frame 4 by alternately changing polarities between adjacent magnets.

This rotor group is driven by the power of the upper motor 7.

When explaining the driving state by Figure 2

When the rotation shaft 6 is rotated by the drive motor, the permanent magnets 4-1 arranged on the outer circumferential surface of the rotor bundle R at the end of the rotation shaft 6 are mounted in the inner direction of the stator bundle F. Rotate in a narrowly spaced state of about 1~2mm from (3-1).

At the same time as this rotation

The magnetic force of the permanent magnet (4-1) generates an induced electromotive force in the excitation coil (3-1) of the other side, so that a current flows to generate power.

At this time, since the permanent magnets 4-1 do not have a magnetic material to be opposed to each other, there is no load caused by cogging, which is pulled by magnetic force.

This constitutes a generator in which the pulling force between the stator bundle (F) and the rotor bundle (R) does not act.

Since this power generation technology has a smaller magnetic force acting on the excitation coil than the conventional power generation method using an iron core that generates an inductive magnetic flux, which has been conventionally used up to now, the amount of power generation is relatively small if the same excitation coil is used.

However, since the amount of energy that rotates the generator for power generation is very small, the power generation efficiency is greatly increased, so that a very economical and eco-friendly generator can be configured.

We expect these technologies to be widely used in all fields of industry.
