Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a natural energy vessel equipped with a high-efficiency generator using a nanomaterial and an ESS system,

The present invention relates to a natural energy ship having a high-efficiency generator using nanomaterials and an ESS system. More specifically, the present invention relates to an energy storage system (ESS), an energy storage system, a system for storing remaining electric power in a battery or the like, and a method for finely dividing an inorganic material or a metal- Nano (Nano) Nanotechnology is produced by bonding nano-heat-dissipative coatings which are processed by binding the inorganic binder and organic binder appropriately. By coating the ship motor, the heat generated by continuous use is dissipated to the outside, And a natural energy vessel equipped with a high-efficiency generator using nanomaterials and an ESS system.

Generally, in the field of motors and generators, there has been a continuing search for methods for providing power and rotating machines with increased efficiency and power density.

As used herein, the term "motor" refers to all types of motors and generators that convert electrical energy into rotational motion and rotational motion into electrical energy.

Such machines include machines, also called motors, generators and regenerative motors.

The term "regeneration motor" refers here to an appliance that can be operated as an electric motor or generator.

Various types of motors are known, including permanent magnets, wound fields, induction, variable reluctance, switched reluctance, and brushes and brushless types.

They can be started directly from a DC or AC source, such as from an electricity utility grid, battery or other alternative source. Alternatively, they may be supplied with a current having a required waveform that is synthesized using an electromagnetically driven circuit.

Rotating energy from any mechanical source can drive the generator. The output of the generator can be connected to the use electronics, either directly mounted or conditioned.

Alternatively, a machine connected to a mechanical source that functions as a source or sink of mechanical energy for different periods of time in the tissue may serve as a regeneration motor by, for example, connecting it through a 4-quadrant operable power conditioning circuit.

The rotator typically has a fixed component known as a stator and a rotational component known as a rotor.

The adjacent surfaces of the rotor and the stator are separated by a small air gap across the magnetic flux connecting the rotor and the stator.

Those skilled in the art will appreciate that the rotor comprises one or more stator coils and one or more stator coils.

Thus, the terms "rotor" and "stator" used herein in connection with rotors refer to rotors and stators in the range of one to three or more.

In fact, all rotors are typically classified as radial or axial air gap types.

In the radial air gap type, the rotor and the stator are separated in the radial direction and the traversing magnetic flux is directed in the direction perpendicular to the rotation axis of the rotor.

On the other hand, in the axial air gap device, the rotor and stator are separated in the axial direction, the flux traversal is mainly parallel to the rotary axis, and the axial air gap device is advantageous in some applications, but the radial air gap type is more widely used And have been studied more intensively.

Except for some specific types, motors and generators generally use more than one type of soft magnetic material.

As used herein, the term "soft magnetic material " means a material that is easily and efficiently magnetized and self-eradicated.

The energy inevitably dissipated in the magnetic material during each magnetization cycle is referred to as hysteresis loss or core loss.

The magnitude of the hysteresis loss is a function of both the excitation amplitude and the frequency.

The soft magnetic material also exhibits high permeability and low magnetic coercivity.

The motor and generator also include a magnetomotive force source that may be provided by one or more permanent magnets or additional soft magnetic material surrounded by current-carrying windings.

Here, the term "permanent magnet material" is also referred to as a " hard magnetic material ", which means a material having a large magnetic coercivity, strong magnetization and resistance to magnetic erasure.

Depending on the type of motor, the permanent magnetic material and the soft magnetic material may be disposed in the stator or the rotor.

Most of the motors produced at present use soft magnetic materials of various grades of electric steel or motor steel, most of which are Fe alloys containing at least one of the alloying elements, especially Si, P, C and Al.

Motors and generators having a stator with a rotor made of an advanced permanent magnet material and a core made of a low loss soft material such as a more advanced amorphous metal have substantially higher efficiencies and power densities than conventional radiative air gap motors and generators , But such axial or radial air gap type machine manufacturing has been less successful. Conventional attempts to apply amorphous materials to conventional radial air gap devices have not been commercially successful. Conventional designs are mainly made of amorphous metal, in which the stator and / or rotor are typically cut into teeth through the inner and outer surfaces. Lt; RTI ID = 0.0 > lamellar. ≪ / RTI > Amorphous metals are difficult because of their unique magnetic and mechanical properties that directly replace conventional steels with commonly designed motors.

For example, U.S. Patent No. 4,286,188 discloses a radial air gap electric motor having a center position rotor constructed by simply coiling an amorphous metal tape strip.

The stator of this design is a conventional stator comprising a conventional lamination laminate provided with a stator winding groove that receives suitable stator winding.

U.S. Patent No. 4,392,073 discloses a stator for use in a radial air gap discharge machine having a center position rotor, and U.S. Patent No. 4,403,401 discloses a method of manufacturing the stator.

The stator is formed by forming a groove in an amorphous metal tape strip, spirally winding the amorphous metal tape having the groove formed thereon into a concave formed annular shape, and winding the wound amorphous metal tape by suitable stator winding.

U.S. Patent 4,211,944 discloses a radial air gap electrical device having a laminated stator or rotor core made from a spatially wound or edge-wound amorphous ribbon with or without groove. A dielectric material is disposed between the amorphous metal ribbons so that they also function as a plate of an integral capacitor.

U.S. Patent No. 4,255,684 discloses a stator structure for a motor made using strip materials and moldable magnetic composites, amorphous metal tapes, and amorphous plates or similar conventional materials. These and other prior art techniques have proven to be difficult to manufacture radial air gap motors using amorphous metals as well as being expensive to manufacture.

Due to various reasons, these efforts were not very competitive and were abandoned because they were not proven to be so competitive compared to conventional Si-Fe motors. However, the potential advantages of the improved radial air gap motor have not been eliminated.

At present, high speed (i.e., high rpm) electrical machines have been manufactured with low pole counts because of the significantly large loss of cores due to the first motor designs of electrical machines operating at larger frequencies. This is mainly due to the fact that the material used in most existing motors is a Si-Fe alloy.

The loss caused by changing the magnetic field at a frequency of 400 Hz or more in a conventional Si-Fe-based material causes the material to be heated and sometimes heated to such an extent that it can not be cooled by means that the device can accommodate.

Various applications such as high speed machine tools, aviation motors and actuators and compressor drives require electric motors that can operate at high speeds, for example, from 15,000 to 20,000 rpm, and sometimes up to 100,000 rpm.

Until now, it is known to be very difficult to provide low-cost electrical equipment that can be easily manufactured using low-loss materials.

In this field, there is still a need for a high-efficiency radial air gap electrical apparatus that eliminates the drawbacks of conventional motors while utilizing the characteristics of low loss materials for the first time.

Ideally, it would be better if the improved motor could convert between mechanical and electrical energy forms at a high efficiency, which could, incidentally, reduce air pollution.

The motor will be less, lighter, and will meet the demands of torque, power and speed required.

The need for cooling is reduced, and motors running on battery power will run longer.

In addition, the electric motor and generator industries have been constantly exploring ways to provide motors and generators with improved efficiency and power density. In recent years, a stator comprising electromagnets having magnetic cores consisting of permanent super magnet rotors (e.g., cobalt rare earth magnets and neodymium-iron-boron magnets) and thin film soft magnetic materials It has been believed that the motors and generators used have the potential to provide sufficiently high efficiency and power density over classical motors and generators. In addition, since a core made of a thin film soft magnetic material can react much more quickly than a typical ferrous core material with respect to a change in magnetic field, a magnetic core made of a thin soft magnetic material has a much faster electric field By having the potential to enable field switching, it enables motors and generators with higher speeds and improved control over typical iron cores.

However, it has proved very difficult to provide a motor or generator that has a magnetic core made of a thin-film soft magnetic material and can be easily manufactured. Moreover, the configurations known so far have not taken full advantage of the performance of these materials, which may be more efficient for certain types of applications.

The conventional motor device of a general ship also includes a motor arranged in the hull and a propeller arranged at the end of the motor shaft extending in a waterproof manner through the hull. As the propeller rotates, the water around the vessel moves, generating a reaction force pushing the vessel forward.

The motor may be a diesel engine or similar internal combustion engine used directly, preferably an electric motor powered by a conventional internal combustion engine, a gas turbine, a nuclear power plant or the like. Adjusting these vessels is conventionally done so that a pivoting rudder is provided to the propeller's wake. The key deflects the wake so as to generate a lateral force component with respect to the longitudinal direction of the ship.

Other types of so-called propulsion units are already known, in which the propeller can be pivoted for the purpose of adjusting the vessel as such. This pivoting operation can be done in a manner that is arranged in a more complicated shaft arrangement or in a motor shaft arranged so that the propeller can rotate about a vertical axis. This latter configuration is referred to as an azimuthhingpropulsion device, which is described, for example, in the applicant's Finnish Patent No. 76977, which is marketed by the applicant under the trademark AZIPOD.

Generally, in the current known Asermouth propulsion unit, an electric motor is arranged in a motor housing which is part of an assembly suitably positioned outside the hull. The assembly is rotatable relative to the vessel. However, a relatively powerful electric motor generates a considerable amount of heat to be removed from the motor, in addition to the actual thrust.

Typically, electric motors are air-cooled because air-cooling is found to be particularly suitable for operation and maintenance. In this case, additional cooling ducts are provided to facilitate service access near the motor. However, one drawback of air cooling is the large space required for the device. There has been an attempt to implement a cooling device that operates as a liquid so that the actual cooling device is located external to the propulsion unit, but in practice such a solution has the advantage that such a lazy moose unit is suitable for rotation Can be made more complicated. Further attempts have been made to construct the motor in such a way that the cooling action is effected through the outer casing of the motor housing surrounding the motor, but these solutions are not satisfactory and require only the use of the motor always on the basis of special operating principles Respectively.

In addition, energy storage devices have been studied extensively as an efficient means for flexibly coping with electric power demand and improving electric quality.

For example, in the internal combustion engine, unbalance of the driving force during one cycle by the fluctuation of the gas pressure and the piston crank mechanism can not be eliminated in the state as it is. If there is a difference between the driving force and the load (load), the rotation speed fluctuates. It is desirable that the machine rotate as smoothly as possible while rotating. So use a flywheel to reduce the fluctuations. In other words, the flywheel is a wheel that is installed to even out the rotational speed, and is mounted on the rotating shaft and has a large moment of inertia to make the rotational speed uniform.

The flywheel energy storage device is an energy storage device through a mechanical energy storage method that converts the rotational energy into rotational kinetic energy by using the inertia of flywheel instead of a chemical storage method such as a battery, and outputs the rotational kinetic energy instantly when necessary. In other words, when energy is stored, electric energy is stored in the flywheel as a mechanical energy through the rotation inertia moment of the flywheel by operating the motor of the electric generator in the flywheel, and the mechanical energy stored in the flywheel is re- Means an energy storage device that operates as a generator and converts it to electrical energy and supplies it to a load.

Flywheel energy storage devices are mainly used for uninterruptible power supply (UPS), power quality improvement, storage of renewable energy such as solar and wind power, and load leveling for fluctuating loads.

However, conventional mechanical flywheels and electronic flywheels are often used for uninterruptible power supply and power quality improvement because long-term storage of energy is not possible because mechanical friction is considerably large or power is continuously supplied from the outside.

(Permanent Magnet Synchronous Motor / Generator: PMSM / G) which is a motor generator used in a conventional general flywheel energy storage device. The superconducting flywheel energy storage device consists of a flywheel composed of a composite material and two superconducting bearings, one at the top and one at the bottom. The superconducting bearing is a journal type bearing and is a vertical axis superconducting flywheel energy storage device in which the shaft rotates vertically.

The superconducting bearing is composed of a portion composed of a superconductor and a permanent magnet. The permanent magnet portion has a structure in which ring-shaped iron is inserted into two magnets magnetized in the axial direction. Here, the permanent magnets are configured such that the magnetic fluxes are radially distributed in such a manner that the same poles face each other. The flywheel, where energy is stored, can be composed of a shaft and a composite wheel made of titanium. The flywheel is constructed to be able to maintain vacuum by inserting it into the chamber in order to eliminate wind damage due to air friction.

The superconductor flywheel energy storage system (SFES) shown in the flywheel energy storage device can store energy for a long period of time and can cope with the electric power demand through efficient use of surplus electric power. Therefore, the utilization of electric energy can be maximized.

Generally, a superconducting flywheel energy storage device (SFES) includes a motor generator having a superconducting magnetic bearing, a rotor, and a permanent magnet.

The rotational kinetic energy of the rotating body can be expressed as a product of the square of the rotational angular velocity and the moment of inertia. The higher the rotational speed, the more efficiently the energy storage capacity can be obtained.

However, depending on how the superconducting flywheel energy storage device (SFES) is constructed, there may be a large difference in energy storage efficiency. In other words, superconducting flywheel energy storage devices (SFES) suffer from loss of stored energy due to wind damage due to air friction, superconducting bearings and motor generators using permanent magnets.

Particularly, when a permanent magnet type synchronous motor / generator (PMSM / G) included in a superconducting flywheel energy storage device (SFES) is driven, an eddy current is generated in accordance with a magnetic flux change generated in an internal permanent magnet.

As a result, the electric current is generated in the electric motor due to the eddy current, and the rotating speed of the rotating body is reduced, thereby reducing the overall efficiency of the superconducting flywheel energy storage device (SFES).

Generally, in a permanent magnet type electric motor generator (PMSM / G) included in a superconducting flywheel energy storage device, a coil is installed in a stator core, a permanent magnet rotates inside the permanent magnet, Are classified into a slot type and a slotless type structure.

Since the slotted structure has a low magnetic permeability because the copper coil is inserted into the slot, the magnetic flux generated from the permanent magnet is generated toward the teeth with high magnetic permeability except for some leakage. Therefore, although the loss due to the copper coil is not so large in such a structure, the loss caused by the teeth of the core is considerably large.

On the other hand, in the case of the slotless type, since the copper coil is exposed to the magnetic flux by the permanent magnet, as the permanent magnet rotates at a high speed, a considerably large eddy current is generated in the copper coil, Causing a loss of energy stored in the device (SFES).

As a result, the eddy current generated by the use of the conventional permanent magnet type electric motor generator (PMSM / G) reduces the rotational speed of the rotating body in the electric motor generator, thereby attenuating the rotational kinetic energy and reducing the energy storage efficiency of the flywheel energy storage device So that the storage device can not function properly.
