Description

Flat Rotary Generators {FLAT ROTARY ELECTRIC GENERATOR}

The present invention relates to a flat rotary generator, and more particularly, to cutting current by cutting magnetic lines produced by at least one disc-shaped magnetic pole structure coaxially using at least one spirally wound coreless toroidal coil structure. And a flat rotary generator which reduces the size and increases the efficiency.

A generator is a machine that converts magnetic energy into electrical energy and basically generates electricity using Faraday's law and Lorentz's law.

There are a variety of generators, but generally they are divided into rotary generator systems and linear generator systems.

In a typical type of rotary generator, a winding (stator) is distributed around the circle and the rotor is provided at the center thereof. To operate the generator, the magnetic field lines are induced by the windings into a permeable material such as a silicon steel sheet or a core inside the windings. However, this creates an attractive force between the magnetic rotor and the permeable material, which acts as a negative force on the rotation of the rotor. This reluctance can be reduced by shortening the distance between the permeable material and the rotor, but in that case the number of magnetic lines intersecting is reduced so that the induced electromotive force is not increased.

As described above, the conventional generator uses the rotation of the magnetic rotor to generate an induced current in the winding of the stator. However, conventional generators using silicon steel sheets or other magnetically permeable cores as a medium for magnetic lines cause eddy current losses that can increase the weight of the generator and increase torque during operation. In addition, core magnetic losses and eddy current losses in the permeable material may reduce the efficiency of generating electricity. As a result, the efficiency of conventional generators is too low for practical use as small generators. In order to solve the above disadvantages, there is a need to develop a flat generator having high efficiency while meeting the request of a small, lightweight, thin and simple generator applicable to a small generator.

It can pass through the Lloyd coil structure, and when the disk type magnetic pole structure is rotated by an external force such as mechanical force, hydraulic power or wind power, the toroid coil structure will cut the magnetic lines passing through the toroid coil structure to generate an induced current. Can be.

In addition, according to another aspect of the present invention, the generator is not equipped with a silicon steel sheet or other magnetically permeable core.

The shaped stimulus structure is coaxial.

Therefore, the present invention can solve the disadvantages of the conventional rotary generator, such as low efficiency, high cost, and size increase caused by using the permeable material in the conventional generator.

In general, induced electromotive force is according to Faraday's law:

Same as

(E is the electromotive force, N is the number of turns, φ is the magnetic flux, and t is the time.)

Since the lines of magnetic force change with the cutting angle of the rotating magnetic field, the electromotive force is not constant. The regular change in electromotive force (Where ω denotes the rotational angular velocity). Therefore, the relationship between the electromotive force and the rotational angular velocity And the effective electromotive force is Where f represents the rotational frequency of the disc-shaped magnetic pole structure. In order to maximize the number of magnetic field lines Φ, it is necessary to improve the conduction efficiency of the loop formed by the magnetic field.

Magnetic induction according to the invention uses a hollow core as a medium. Preferably, a plurality of disks are arranged on each side of the toroidal coil structure such that more magnetic lines of force pass through the coil so that the magnetic lines of force pass through the spiral coil structure from one magnetic pole structure to the other magnetic pole structure. While forming a shaped magnetic pole structure, those skilled in the art will understand that one disc shaped magnetic pole structure may be used.

Without a core or silicon steel sheet, the electromotive force can be obtained by rotational speed and magnetic force:

Therefore, the technique of the present invention can be used as a generator of various electronic products to obtain the maximum magnetic flux, to reduce the use of batteries and to reduce the pollution associated with power generation.

1 shows a schematic diagram of a preferred embodiment according to the invention. The flat rotary generator includes a disc-shaped magnetic pole structure 2 coaxial with the toroidal coil structure 1. The toroidal coil structure 1 may comprise a single spiral winding or a plurality of spiral windings connected in series. When the toroidal coil structure 1 is fixed, the disk-shaped magnetic pole structure 2 rotates. On the other hand, when the toroidal coil structure 1 rotates, the disc-shaped magnetic pole structure 2 is fixed. In this embodiment, although a single magnetic pole structure can be used as a substitute for reducing the current, a spiral coil structure 1 is used to cut the magnetic lines of force between the two disc-shaped magnetic pole structures 2. The disc-shaped magnetic pole structure 2 is located parallel to the side of the toroidal coil structure 1. The disc-shaped magnetic pole structure 2 and the helical coil structure 1 have an air core not employing any permeable material. The magnetic lines of force generated by the two disk-shaped magnetic pole structures can pass through the helical coil structure. When the disc-shaped magnetic pole structure or the toroidal coil structure rotates by an external force, the toroidal coil structure 1 cuts the lines of magnetic force to induce a current. External forces may include vibrational forces, rotational forces, or any other force that causes relative motion of the coil and the magnetic pole structure.

Figure 2 shows another embodiment of the present invention, wherein the generator is not provided with any permeable material, such as a silicon steel sheet or other permeable core structure, and the plurality of spiral coils and disc-shaped magnetic pole structures are alternately parallel. It is arranged.

3 shows the operation of the disc-shaped magnetic pole structure 2 according to the present invention. The magnetic poles of the two disc-shaped magnetic pole structures 2 are opposite in polarity so that opposite polarities face each other during stop and rotation. The toroidal coil structure 1 is located between these disc-shaped magnetic pole structures to cut magnetic lines of force. Although the figure shows only two poles in each disc-shaped magnetic pole structure 2, the present invention is not limited to this.

4 is a plan view of an example of a disc-shaped magnetic pole structure 2 according to the present invention. Each magnetic pole in the disc-shaped magnetic pole structure 2 is a section bounded by two radii. 5 (a) and 5 (b) are side views of FIG. The sections of the disc-shaped magnetic pole structure 2 are arranged in series of N-S poles.

6 (a) and 6 (b) show the winding structure of the toroidal coil structure 1 of the present invention. 6 (a) shows a circular winding structure, and FIG. 6 (b) shows a non-circular winding structure. In either case, the toroidal coil structure can be wound into a stacked or non-stacked, interlaced or noninterlaced, or any suitable configuration. This winding is wound on a material such as an epoxy resin.

Finally, since the theory applied to the motor is equally applicable to the generator, it is possible to implement the motor using the present invention.

For example, the toroidal coil structure may generate current by supplying current from an external source to the toroidal coil structure. If so, the disc-shaped magnetic pole structure will rotate due to the repulsive force generated by the generated magnetic field.

While specific embodiments have been shown and described, it will be apparent to those skilled in the art that various changes may be made without departing from the spirit of the invention, which is limited only by the appended claims.
