Description

Generator with poles on both sides of armature frame made of pressed pulp

Without electricity, our way of life would go back to the old days, and our highly civilized life would not be possible at one moment.

Electricity, which plays a very important role in modern life, comes from generators, and we overlook the importance of generators.

The conductors that generate electricity in the generator are inserted into the slots of the armature frame and the armature rotates with a slight gap with the magnet.

The armature uses a layer of thin iron plate containing silicon to reduce the iron hand, which consists of the hysteresis hand and the eddy current hand.

Generator losses consist of mechanical and electrical losses (resistance and iron losses of windings, and drift load losses). Electrical losses are approximately 3.5 [%] of generator capacity, with 35 [Kw] for 1000 [Kw] generators. Is released as heat by electric hands.

Iron loss and drift load loss are generated by the armature. The electrical loss of the generator is about 37 [%]. When the eddy currents causing the iron loss and drift load loss are reduced, 13 [Kw] It is possible to reduce the fever.

The armature of a conventional generator minimizes the losses caused by eddy currents by using a thin sheet metal lamination method that includes silicon.However, if the armature frame material has relatively small magnetic permeability but insulation characteristics, The loss can be made smaller.
Technical background of the present invention is disclosed in the Republic of Korea Patent Office (Reg. No. / date: 1008707380000 / 2008.11.20) as 'FAPM coreless multi-generator and motor.'

In addition, if the N pole and the S pole are arranged correspondingly around the coil installed in the armature frame to secure the passage of magnetic flux, the decrease in permeability is compensated for and the leakage magnetic flux is reduced, so there is no problem in using it as a generator. It seems to be.

Renewable energy in nature is almost infinite, such as wind and wave power, but for the general purpose of distribution, it is necessary for the equipment designers to supply the core parts of the power generation equipment desired by the facility designer.

For a wind power installation, it is necessary to purchase a generator for the purpose of the designer's desired method, but at present, it is difficult to purchase a generator for the purpose of small and medium or small capacity because it was developed for large-scale power generation centered on a large company.

In order to increase the rate of securing renewable energy like in Europe, it must be widely installed on windy coasts or in the mountains and used universally.

To this end, the generator in the present invention reduces the electrical loss of the generator by reducing the amount of iron used in the armature, and also generates electricity by the permanent magnet at the beginning, the generation of magnetic flux during the generation of permanent and electromagnets Using a hybrid method, the electromagnet will control the generated power and rotation speed.

The armature frame of the generator is made by pressing and drying the pulp, and the N pole and the S pole are installed on both sides of the coil inserted in the armature slot.

The structure of the generator consists of a triple of outer cylinder, middle cylinder and inner cylinder, and the axis of rotation of the generator penetrates the center of the circle made by the inner diameter of each of the outer and intermediate layers and the inner cylinder.

The inner cylinder has a certain length removed in the middle of the length, and both inlet disks of the inner cylinder are fixed to the center of both sides of the inlet disk of the outer cylinder, so that the inner and outer cylinders form a bundle, fixed in the middle of the middle layer cylinder. The finished iron disc is inserted between the removed portions of the inner cylinder center part.

An intermediate layer cylinder made of pressed pulp serves as an armature frame, an electromagnet is installed on the outer cylinder, and a permanent magnet is attached to the inner cylinder.

By using compressed pulp in the armature frame of the generator instead of laminated silicon steel sheets, it is possible to reduce about 37 [%] of generator electrical losses, which results in a reduction in weight and temperature.

Since the N pole and the S pole are arranged to correspond to both sides of the armature coil, the coil is arranged in the middle of the magnetic flux path to compensate for the disadvantage of the compressed pulp having a relatively small permeability and to reduce the magnetic flux leaking in the air.

By using a hybrid method of permanent magnets and electromagnets, power is generated by permanent magnets without using an electromagnet at the beginning of power generation, and there is an advantage of controlling the generated power and rotational speed by controlling the magnetic flux density of the electromagnet.

Important matters of the present invention can be easily manufactured using a cylinder, so the manufacturing cost is reduced, and thus, the generator price is lowered, and thus, it is determined that it will contribute to the general purpose of the wind generator.

1 is a perspective view of a generator having poles on both sides of a coil of an armature frame made of pressed pulp according to the present invention.

Renewable energy in nature is almost infinite, such as wind and wave power, but the ratio of nuclear power and thermal power generation can be reduced only when the generator for energy recovery is universally supplied.

The two sides are fixed at each end to form one bundle in rotation.

The generator rotary shaft 4 is fitted into the hole of the bearing 6 provided in the center of the disk 5 of the cylindrical inlet in both the outer cylinder 1 and the inner cylinder 3, respectively.

At the center of the cylinder length of the inner cylinder 3, a 10 [%] cylinder of the inner cylinder length is removed, and a 10 [%] cylinder is removed and each of the permanent magnets 7 is disposed on the outer surface of the inner cylinder arranged on both sides. N and S poles are attached.

The permanent magnet 7 of the inner cylinder 3 is characterized in that power generation is possible without the excitation of the electromagnet at the beginning of power generation.
