Description

[0001] Equipment for generating electricity [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generating device, and more particularly, to a power generating device that uses a rotor and a stator to increase power generation efficiency.

Generally, a motor is a device that converts electric energy into mechanical work by using the force that current receives in the magnetic field. Most motors produce power for rotational motion but also implement linear motion. On the other hand, a generator is a device opposite to an electric motor and produces electricity using mechanical energy. The motor and the generator can replace each other and replace it.

Here, the electric motor is divided into a DC motor and an AC motor according to the type of power source, and the AC motor is divided into a three-phase alternating current and a single-phase alternating current.

And the induction motor can be directly connected to the power source, it is simple in structure and robust, but it is the most widely used in the world because it is cheap and easy to handle.

Such an induction motor is composed of a non-rotating stator and a rotatable rotor. When an electric current for generating a rotating magnetic field is supplied to the stator winding, induction current flows to the rotor winding by electromagnetic induction, .

However, such a general motor is driven by receiving electric energy through a current supplying means such as an electric power source and a battery. When the electric current supply is interrupted, the motor is also stopped.

For example, transportation means such as an electric car and an electric scooter driven by the power of the battery and various industrial machines are required to charge the battery periodically before the battery is discharged, and in the case of an electric car, a large amount of batteries must be loaded .

In addition, there are many kinds of generators that can get electric energy, and there are various methods. Generally, there are various kinds of electric power generators such as hydroelectric generators using nature, wind power generators using wind power, solar generators using solar heat, and tidal generators using seawater Are widely used, and thermal power generators for burning anthracite or coal crude oil and natural gas, and nuclear power generators using nuclear reactors are widely used.

In this way, generators that generate electricity by burning anthracite, crude oil, and natural gas are depleted of resources due to fuel consumption, and the exhaust gas from fuel combustion pollutes the atmosphere, thereby causing global warming problems. Furthermore, hydroelectric generators and wind generators are closely related to natural environments and conditions, and there are limitations, and there is a problem that installation costs are large. In addition, the nuclear power generators have a problem in terms of equipment cost due to the large- There is pollution problem and inhabitants' objection problem. Solar energy, wind power, hydro power, tidal power, hydrogen gas, and bio energy have been developed and used because of these problems, but they are not enough to be used directly as electric energy for individuals, industries, and transportation means.

On the other hand, as described above, the electric motor is a device that generates power by rotating the shaft by the electric power of the coil wound around the rotary shaft and the magnetic force of the permanent magnet, and is used in various places such as automobiles, electric motors, do.

In addition, generators are based on a common principle that they generate electromotive force by electromagnetic induction, and the magnitude of this electromotive force depends on the intensity of the magnetic field, the length of the conductor, the magnetic field and the conductor And the direction of EMF can be found by Fleming 's right - hand rule.

Here, the generator is constructed of a strong magnet for generating a magnetic field and a conductor for generating an electromotive force, and one of them must be able to operate.

In addition, there is an example in which a permanent magnet is used in a very small generator. However, in general, an electromagnet is used in which an account coil is wound around an iron core and a direct current flows through the coil. In this case, You can freely change the size.

As described above, many generators have been proposed, but there is a problem that a part of the power generated by the back electromotive force or other conditions is leaked. Therefore, there is a need for a generator with high efficiency.

BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and further aspects of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

FIG. 1 shows a structure of a power generator including a stator and a rotor according to an embodiment of the present invention. Hereinafter, a structure of a stator and rotor-powered generator according to an embodiment of the present invention will be described in detail with reference to FIG.

1, the power generation apparatus includes a stator and two rotors. Of course, other configurations than those described above may be included in the power generation apparatus proposed by the present invention.

The rotor 105 is formed of a circular plate having a predetermined thickness and includes a first surface and a second surface corresponding to the first surface. On the first surface, permanent magnets 105a are arranged on the circumference at regular intervals based on the center of the rotor 105. [ The permanent magnets 105a are disposed so as to alternate polarities on the circumference of the rotor 105. [ That is, as shown in Fig. 1, permanent magnets 105a are arranged in the order of S pole, N pole, S pole, N pole, ... on the circumference of the rotor 105. Of course, the rotor 105 may be provided with a permanent magnet in addition to a circular plate, and any other form other than a circular plate may be used as long as it is rotatable.

As described above, the present invention includes two rotors 105, and the two rotors 105 are spaced apart from each other by a certain distance. The permanent magnets 105a are arranged so as to have the same polarity on the opposing surfaces of the rotors 105 spaced apart by a certain distance. That is, when the permanent magnets are arranged in the order of the S pole, the N pole, the S pole, the N pole, and so on in the inner side of one rotor, the inner side of the other rotor also has S pole, N pole, S pole, Place the permanent magnets in order.

A stator 110 is positioned between two rotors spaced a certain distance apart. The stator 110 is also made of a flat plate having a predetermined thickness. The stator 110 is formed with at least two cores in which the coils are wound. In connection with the present invention, the core consists of two types. That is, one core is the power generation core 110b and the other core is the drive core 110a. The power generation core 110b is a core that generates electricity by rotation of the rotor, and the drive core 110a refers to a core that receives electricity to rotate the rotor.

That is, as shown in FIG. 1, the stator 110 is composed of a power generation core 110b and a driving core 110a, and three power generation cores 110b are shown. However, the number of the power generating cores formed in the stator 110 may be three or more than the number of the power generating cores 110b. Of course, when there are a plurality of the number of the power generation cores 110b formed in the stator 110, the power generation cores 110b are formed in the same angular unit with respect to the rotation axis 115. That is, according to FIG. 1, when three power generation cores 110b are formed, the power generation cores 110b are arranged at intervals of 120 degrees with respect to the rotation axis 115. Of course, when the number of the power generation cores 110b is four, the power generation cores 110b are arranged at intervals of 90 degrees with respect to the rotation axis 115. [ Described in more detail, the number of the power generating cores is at least two or more and is formed in the same angular unit with respect to the rotation axis.

The induction current is generated in the power generation core 110b by the permanent magnet 105a formed in the rotor 105 when the outer rotor 105 rotates.

As described above, the stator 110 has the driving core 110a in addition to the power generating core 110b. 1 shows a stator 110 in which two driving cores 110a are formed. As shown in FIG. 1, the driving core 110a is also formed in the same angle unit with respect to the rotating shaft 115. [ That is, according to FIG. 1, when two drive cores 110a are formed, the drive cores are arranged at intervals of 180 degrees with respect to the rotation axis 115. Of course, when the number of the driving cores 110a is three, the driving cores 110a are arranged at intervals of 120 degrees with respect to the rotating shaft 115. [ As described above, the driving core 110a receives a current from the outside, and the driving core 110a performs the function of the electromagnet by the supplied current.

The driving core 110a has a polarity different from that of the permanent magnet 105a when the permanent magnet 105a formed on the rotor 105 is in close proximity to the permanent magnet 105a, 105a and the driving core 110a. When the attractive force acts between the permanent magnet 105a formed on the rotor 105 and the driving core 110a, the rotational speed of the rotor 105 increases. When the rotor 105 rotates to bring the permanent magnet 105a formed on the rotor 105 and the drive core 110a closer to each other, the current supplied to the drive core 110a is cut off. As described above, according to the present invention, the driving core 110a, which supplies current to the driving core 110a constituting the stator 110, performs the function of the electromagnet, The polarity of the permanent magnet 105a adjacent to the driving core 110a performing the function of the polarity and the electromagnet is formed to be different. The driving core 110a and the permanent magnets 105a are arranged such that the polarity of the driving core 110a performing the function of the electromagnet and the polarity of the adjacent permanent magnet 105a are different from the driving core 110a performing the function of the electromagnet, Thereby allowing the attraction force to act between them.

In particular, the power generating apparatus of the present invention supplies current to any one of the driving cores 110a, not to all the driving cores 110a at the same time. That is, at any point in time, only one of the plurality of drive cores 110a performs the function of the electromagnet.

Hereinafter, a method of supplying current to the driving core will be described.

Figure 2 shows a rotating shaft on which the rotor is rotated in accordance with one embodiment of the present invention. Hereinafter, the structure and function of the rotating shaft in which the rotor rotates according to an embodiment of the present invention will be described in detail with reference to FIG.

2, the rotating shaft 115 is coupled to the rotor, and the rotor rotates about the rotating shaft 115. [ The rotating shaft 115 passes through the center of the stator in a state of being coupled with the rotor of one side, and then fixedly engaged with the rotor formed on the other side. And the rotary shaft 115 fixedly coupled to the rotor formed on the other side is extended by a predetermined length.

The rotating shaft 115 forms at least two contact terminals. For example, the rotary shaft 115 includes a ground terminal 115a, a current production terminal 115b connected to a current generated in the power generation core, and a current supply terminal 115c connected directly or indirectly to the current production terminal 115b. The ground terminal 115a is a reference terminal, and the current production terminal 115b is a terminal for supplying a current generated in the power generation core to the outside. The current supply terminal 115c is a terminal for supplying a part of the current produced by the current production terminal to the drive core.

To this end, a connection terminal connected to the contact terminals 115a to 115c formed on the rotary shaft is formed near the rotation axis. The connection terminals are formed in the same number as the contact terminals, and when three contact terminals 115a to 115c are formed as described above, three connection terminals are also formed.

FIG. 3 illustrates shapes of a current producing terminal and a current supplying terminal formed on a rotating shaft according to an embodiment of the present invention. Hereinafter, the shapes of the current producing terminal and the current supplying terminal formed on the rotating shaft according to the embodiment of the present invention will be described in detail with reference to FIG.

Particularly, Fig. 3 shows a developed development of the current production terminal and the current supply terminal formed on the rotary shaft.

According to Fig. 3, the current production terminal and the current supply terminal are connected, so that the current generated in the power generation core is supplied to the current supply terminal as well as the current production terminal.

According to Fig. 3, the current generating terminal 115b is formed on all circumferential surfaces of the rotating shaft, whereas the current supplying terminal 115c is formed on a part of the circumferential surface of the rotating shaft. As described above, the present invention supplies current to only one of the driving cores, not to all of the driving cores formed in the stator at a specific point in time. Therefore, when the current supply terminal 115c is formed on all circumferential surfaces of the rotating shaft, current is supplied to all the driving cores formed in the stator at a specific point in time. Therefore, the present invention forms a current supply terminal 115c on a part of the circumference of the rotating shaft to supply current to one of the driving cores formed in the stator at a specific point in time. For example, when the number of drive cores formed on the stator is two, the present invention forms a current supply terminal on the circumference of the rotation axis at a half or less of the circumference of the circumference. In other words, when the number of driving cores is n, the present invention forms a current supply terminal of less than 360 / n (unit: °) of the circumference on the circumference of the rotating shaft. In other words, the length of the current supply terminal formed on the circumference of the rotating shaft is inversely proportional to the number of power generation cores formed in the stator.

On the other hand, the current generating terminal 115b is formed on all the surfaces of the rotating shaft so as to receive all the currents generated in the power generating core. Of course, according to the intention of the designer, the current production terminal can be formed only on a part of the rotational axis.

That is, the current producing terminal is formed on a part of the rotating shaft, and the connecting terminal does not always contact the current producing terminal but contacts the current producing terminal at regular intervals. In this case, when the current production terminal is contacted at a predetermined periodic interval, the current production efficiency can be increased.

The current generated by the generator can be stored in the battery using charge and discharge capacitors.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the scope of the present invention .
