Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a generator using two-

The present invention relates to a generator using two rotatably divided magnets, and more particularly, to a generator in which a core of a stator is formed into a magnetic iron core of a strong magnetic body, and then a coil is wound to form a magnetic field between the rotor and the stator In the present invention, the rotating shaft is placed, but the stator is not rotated. The stator is wound around the core formed of a complex soft material or non-conductor. And the first rotor and the second rotor formed of a plurality of magnets divided by the stator are rotated at the same time in the same direction and a magnetic field is generated between the first rotor and the stator and between the stator and the second rotor And generates an electromotive force. Since the stator uses a complex soft material or a core formed of a non-conductor, it keeps the magnetic field with the two rotors and makes them lose the force to stop them. The first rotor and the second rotor are attracted to each other, , But they are rotated at the same speed at the same rotation angle as the same direction by the magnetic force. Therefore, the present invention relates to a generator capable of increasing power generation efficiency by reducing cogging torque and reducing eddy current and heat generation while reducing rotational resistance.

The present invention relates to a generator using two magnets in which a rotor is divided by a plurality of magnets, and more particularly to a generator in which magnets are divided into a plurality of magnets The rotating coils of the stator located between the first rotor and the second rotor can be rotated while generating a magnetic field therebetween, thereby reducing the rotational resistance of the rotor and increasing the efficiency of the electric power, To the generator.

The magnitude of the electromotive force generated by the generator is proportional to the strength of the magnetic field, the length of the conductor, and the relative speed of the magnetic field and the conductor. Therefore, the electromotive force can be increased by increasing the intensity of the magnetic field, by forming the conductor longer, or by increasing the relative speed of the magnetic field and the conductor. Generally, the relative speed of the magnetic field and the conductor is increased to increase the electromotive force. To do so, the rotation speed of the rotor must be increased. However, in conventional generators, rotational resistance, cogging torque, eddy current, and heat generation have become a problem by using a conductor for the stator.

A generator capable of obtaining desired maneuverability and electromotive force by using a non-conductor for a stator and two rotors has been developed, and an example of the generator of the 10-1454805 is shown in FIG.

5 has a structure in which an electromotive force is obtained at a low rotational speed by rotating the rotor 120 having a magnet and the inner casing 150 as a magnetic body or a conductor in the same direction. Advantages include a rotor 120 having a magnet, And the inner casing 150, which is a magnetic body or a conductor, to induce a magnetic field in the coils wound on the composite soft material or the core formed of the non-conductor. When the stator 130 generates electromotive force, The cogging torque phenomenon and the eddy current are suppressed, the heat generation suppressing effect and the rotation (rotation) of the inner casing 150 are maintained, while the attraction of the inner casing 120 and the inner casing 150 is maintained, The resistance can be greatly reduced and the power generation efficiency can be increased.

However, in the conventional generator described above, the rotor and the inner casing (second rotor) are fixed to the rotating shaft, and at the same time, the rotating resistance is reduced by rotating at the same rotational angle in the same direction. However, So that it can not be manufactured to be slim and compact, and there is a problem in joining with frames of electric motorcycles and electric vehicles.

Therefore, in the present invention, the first rotor is slipably joined to the intermediate portion of the rotating shaft by using a first rotor coupling bushing to be different from the conventional generator, , One side of the second rotor is slidably coupled to the outer circumferential surface of the sleeve a surrounding the second rotor coupling bushing and the shaft and the other is connected to the second rotor coupling bushing or sleeve a in the direction parallel to the rotation axis The first and second rotors are formed by forming a through hole so that the wiring can be led out safely to the outside and the first rotor is rotated by the external second rotor when an external force is applied to the rotating shaft and the second rotor, And strong magnetic force, it can not be attached directly, but pulled and attracted by magnetic force, at the same time it forms the same rotation angle as the same direction, Is a technology.

SUMMARY OF THE INVENTION The present invention has been devised in order to solve the problems of the conventional art described above. An object of the present invention is to provide a generator that uses a magnet having two rotors divided by a stator and is connected to a rotating shaft so as to simultaneously rotate the first rotor and the second rotor, By using one rotor with a large number of magnets in the stator, a strong magnetic field is formed between the iron core and the rotor composed of the stator conductors, and the rotational resistance is very strong due to the force to be stuck to each other. In order to solve this problem, the core, which is the iron core of the stator, is formed into a composite soft material or non - conductor, and the field core of the stator is formed outward and used as the second rotor. As a result, although a stator is formed on a core composed of a complex soft material or a non-conductor, a strong attraction between the first rotor and the stator and the second rotor causes attraction between the first rotor and the second rotor However, since the rotary shaft, the first rotor and the second rotor simultaneously rotate in the same direction and at the same rotation angle at the same rotation angle, the rotation resistance is reduced, and the cogging torque, the eddy current and the heat dissipation effect And to provide a generator capable of obtaining an electromotive force.

In order to accomplish the object of the present invention, the present invention provides a rotor comprising a first rotor connected to a rotating shaft by slip using a first rotor coupling bushing, and a core formed of a composite soft material or non- A stator which is coupled between the first rotor and the second rotor so that one side is not rotated using the sleeve a and the other side is coupled to the rotary shaft by slip using the stator coupling bushing, A winding coil which is wound on a core formed by a sieve and connected to external wiring, a second coil which is slip on one side of the sleeve a by using a second rotor coupling bushing, And an electric power source for generating electric power.

The rotary shaft of the generator using the two rotatably divided magnets of the present invention can be supported by the shaft supports a, b.

Further, the first rotor, the stator, and the second rotor may be provided on the outer circumferential surface of the rotating shaft.

Both ends of the rotating shaft can be wrapped using the sleeves a and b.

Further, the sleeve a can form the wire through hole in the axial direction.

The first rotor may be formed of a plurality of magnets divided into a plurality of magnets, coupled to the outer circumferential surface of the center of the rotor shaft by a first rotor coupling bushing, and freely rotatable from the rotor shaft.

In addition, it is possible to prevent the first rotor from moving to the left and right using a circlip where the first rotor is slip-coupled with the rotation shaft.

Further, the stator is positioned between the first rotor and the second rotor, and the core for winding the coil can be formed into a composite soft material or non-conductor.

Further, in order to support the stator, the stator side plate a can be fixedly held at the center of the stator by using the sleeve a.

The stator side plate b can be slip-coupled to the rotary shaft using a stator coupling bushing at the center of the stator.

The second rotor side plate a is slipably coupled to the outer circumferential surface of the sleeve a using a second rotor coupling bushing, and the second rotor side plate b And can be fixedly coupled to the rotary shaft.

The second electromagnetic coupling bushing or the sleeve a can form the wire through hole in a direction parallel to the rotation axis.

According to the generator using the two-rotor magnet divider of the present invention, when the first rotor and the second rotor formed of a plurality of magnetically divided magnets rotate at the same time, the two rotors are stuck due to the magnetic field between the stator and the rotor The first rotor and the second rotor simultaneously rotate in the same direction and at the same rotational angle to rotate at equal speed so that the rotational resistance is reduced and the two rotors and the stator The cogging torque phenomenon and the eddy currents can be eliminated and the relative speed can be increased, so that a desired electromotive force can be obtained.

Further, since the present invention has a core composed of a composite soft material or a non-conductor, it can eliminate the eddy current and dissipate the heat generation to improve the durability of the coil, and reduce the cogging torque and rotation resistance, There is an advantage of saving power energy.

Further, the present invention is advantageous in that the structure of the generator is simplified by the relatively simple coupling and the external derivation of the wiring, and the manufacturing process applied to the frame of the wind power, the auxiliary power and the electric car is advantageous.
