The present invention relates to a magnetic amplification engine for converting the magnetic energy of the permanent magnet into mechanical energy.

An electric motor is a device that converts electrical energy into mechanical energy and consists of two parts called stators and rotors. The rotor consists of a conductor and a magnetic body, and in most cases has a contact element called a slip ring or commutator.

This connects the rotor with external circuitry. In addition, the rotor is equipped with a bearing, a support shaft cooling fan, etc. The stator is composed of a conductor and a magnetic body necessary to create a magnetic field like the rotor, in addition to a housing supporting the entire motor. How are the conductors arranged? This determines the type and characteristics of the motor.

An important law in understanding the working principle of the motor is the Fleming's left- and right-handed law, when a current flows in a conductor placed in a magnetic field, the force acts on the conductor.The index finger of the left hand moves in the direction of the magnetic field and the middle finger in the direction of the current. Fleming's left-hand rule is the principle that the direction of the thumb, perpendicular to them when directed, coincides with the direction of the force, known as Lorentz's force.

The history of the development of electric motors originates in the early 19th century when Oersdade discovered that magnetic fields were generated from the movement of electricity.The current prototype of the AC induction motor was developed in 1888 by Nikola Tesla and achieved commercial success. It is rooted in what is gathered.

Induction motors are wound around two sets of windings, which are connected to an external power source and create a rotating magnetic field in a narrow space between the stator and the rotor. The other group of windings is called the secondary winding and is wound on the rotor.

This creates a closed circuit independent of the group of windings on top of it, and when the magnetic field created by the primary winding moves over this secondary winding, an electromotive force is generated in the secondary winding according to Fleming's right hand law, and the secondary winding creates a closed circuit. There is an electric current, like an electromotive force, between which the force follows the Fleming's left hand law and the rotor generates rotational power. AC induction motor is basically a device with a constant rotational speed and is the most commonly used electric station due to its simple structure and high efficiency.

In contrast, synchronous motors, like induction motors, usually have a winding that creates a rotating magnetic field, and its structure is the same as the primary winding of an induction motor (this is called an armature winding), but the rotor is different from that of an induction motor. It has a field configured to generate a magnetic field with a constant polarity.For example, in a two-pole synchronous motor, a direct current flows through a slip ring on a winding on a rotor to make one N-pole and S-pole. A winding that is wound on a rotor to create a set of magnetic poles is called a field winding) .If the rotor is rotated at the same speed as a rotating field made from a stator, the magnetic poles of the stator and the rotor are attracted to each other so that the rotor The motor rotates at the same speed and gains power. The synchronous motor winds the armature winding around the stator. Since rotation is referred to as a synchronous motor.

However, such motors have high efficiency in obtaining rotational power, but mechanical loss (friction or heat generation) cannot be avoided in any way, so the output energy has to be smaller than the energy input at all times.

In view of this, the applicant has proposed an engine driven by the repulsive force of permanent magnets and electromagnets through Korean Patent Application No. 2006-92777 (name: magnetic amplification engine).

The above application is provided to the rotor and the stator so as to oppose the electromagnet and the permanent magnet to each other with the polarity to the opposite direction, the power is rotated through the rotating shaft that rotates with the rotor by causing the rotor to rotate by a repulsive force acting constantly between the magnets on both sides This is how you get it.

However, the above-mentioned application is still effective in that the driving energy obtained by using the power of the permanent magnet is larger than the power delivered to the actual electromagnet, but the direction of the rotational force of the rotor with respect to the repulsive force acting between the two magnets is Since it appears in the orthogonal direction, the power efficiency is lowered due to the inconsistency of the force action direction.

Therefore, the present invention has been proposed in view of the above point, and its purpose is to improve the efficiency of electrical energy input by using the energy of permanent magnets, but the direction of action of the suction and repulsive force of permanent magnets and electromagnets By reciprocating the linear movement of the piston in the same direction as, and converting the reciprocating linear movement of the piston into the rotational movement through the crank mechanism to obtain mechanical energy, the magnetism of the structure that can continuously obtain more output energy than the input electrical energy To provide an amplification engine.

       Small end portions 49a and 50a of the connecting rods 49 and 50 are capable of rotational movement by the pin shafts 47 and 48 on at least one side, preferably both sides, of the piston shaft 2 forming the long axis. The large ends 49b and 50b on the other side of the connecting rods 49 and 50 are rotatably connected to the crank pins 53 and 54 of the crank shafts 51 and 52.

        The crank pins 53 and 54 may be manufactured by integrally processing the main body with the crank shafts 51 and 52 so as to have an eccentricity, or the crank pins 53 and 54 may be separately made as shown in FIG. It is possible to assemble and mount the shafts 51 and 52. The crankshafts 51 and 52 are rotatably supported by the bearing supporters 55 and 56 having rolling bearings, and the bearing supporters 55 and 56 are fixed to the base plate 12 again.

The moving stroke distance of the piston shaft 2 is twice the eccentric distance of the crank pins 53 and 54 with respect to the center point of the crank shafts 51 and 52, and the eccentric distance of the crank pins 53 and 54 is an electromagnet of both sides. It is designed to be less than 1/2 of the total space distance minus the thickness of the piston 14 from the total space distance between (24) and (25).

The upper and lower dead centers of the crank pins 53 and 54 are either one of the two-axis crank shafts 51 and 52, and the crank pins when the crank shaft overlaps with the crank shaft in a state where the crank shaft and the connecting rod are in a straight line. If the position is expressed as top dead center, the positions of the crank pins when all of them are unfolded in a straight line are defined as bottom dead center, and in the representative meaning of all of them, the inflection point or the turning point is referred to below.) The sensor 57 is installed in the bearing supporter 55 or the guide plate 37, and the position signal of the inflection point (upper and lower dead center) of the piston 14 and the crank pins 53 and 54 detected from the sensor 57. Is applied to the control unit (which can be configured as a relay) to control the control unit 58 to switch the power supply direction of the power supply unit 65.

The crankshafts 51 and 52 can be used as driving sources for automobiles and various prime mover devices by connecting power transmission devices 59 and 60 to one end thereof, for example, a belt pulley device or a transmission by gears. As shown, when the crank shafts 51 and 52 are installed on both sides, the electricity generated from the generator 61 on the crank shaft 51 on one side is used for supplying power for the excitation of the electromagnets 24 and 25. Can be used.

The crank shafts 51 and 52 are formed with long long shafts such that a plurality of crank pins 53 and 54 are continuous along the shaft, like the crank shaft of a four cycle engine, and is connected to each crank pin 53 and 54. The rods 49, 50, the piston shaft 2, the piston 14, and the like are installed in parallel, and these devices are again fixed to be supported by the base plate 12.

And the left and right support means (3,4) is fixed by connecting a plurality of support rods 62 across both sides to withstand the reaction force in the axial direction due to the repulsion and suction force of the strong permanent magnet and electromagnet.

In addition, a cooling jacket 63 is formed in the bush holders 5 and 6 so that the piston shaft 2 cools the frictional heat according to the reciprocating movement.

Hereinafter, the operation of the magnetic amplification engine 1 according to the present invention will be described in detail.

For illustration, the permanent magnet 19 of the present invention assumes that the right side of the piston 14 is fixed to the N pole and the left portion of the piston 14 is fixed to the S pole.

When power is supplied to both electromagnets 24 and 25 by turning on the power supply means 65, the power of the permanent magnets on the right is initially supplied when power is supplied such that the electromagnets 24 and 25 have N poles. Since the north pole of the pole and the electromagnet repel each other, and the south pole of the permanent magnet on the left side and the north pole of the electromagnet are attracted to each other, the piston 14 and the piston shaft 2, which are subjected to great force in the left direction, move to the left direction. The slide is moved.

When the piston 14 starts to move to the left, the connecting rod 49 on the right side, which is pulled by the piston shaft 2, rotates to the 2/4 quadrant position starting at 0 ° and through the quarter quadrant position. The connecting rod 50 on the left side, which is gradually extended with the piston shaft 2 while being moved, and receives the force pushed out by the movement of the piston shaft 2 to the left side, is connected to the crank pin 54. Is moved from the 0˚ position through the quarter quarter position to the 2/4 quadrant position (counterclockwise), and the connecting rod 50 and the crank pin 54 overlap each other when viewed from the front. By the movement of the connecting rods 49 and 50, the crank shafts 51 and 52 on both sides rotate in a counterclockwise direction.

In this way, the piston 14 moves while compressing the return spring 46 on the left side, and the limiting point (the piston is close to the electromagnet on the left side, at this time, the connecting rod on the left side and the piston shaft are in a state where they overlap in a straight line, (The piston shaft on the right side and the connecting rod are in a straight line), and the crank pin is positioned at 180 °.

The sensor 57 detects this and controls the control unit 58, which is a kind of relay switch device, to control the power supply unit 65 to change the + and − power supply to the electromagnets 24 and 25.

When the power supply direction to the electromagnets 24 and 25 is changed, the polarities of the electromagnets 24 and 25 are switched from the N pole to the S pole, so that the piston 14 and the electromagnet 25 which are almost close to each other on the left side are the same. The S pole has a strong repulsive force acting, and the opposite side, that is, the right side, the N pole and the S pole are attracted to each other, so the piston 14 changes direction and starts moving to the right side.

At this time, the return spring 46 on the left side pushes the piston 14 to the right by applying force to the piston 14, and when the piston shaft 2 starts to slide to the right by the piston 14, The connecting parts of the crank pins 54 and 54 of the necking rods 49 and 50 start to move toward the 3/4 quadrant due to the inertial force that moves in the counterclockwise direction, and the piston 14 moves to the right limit point (direction change point). ), The crank pins 53 and 54 reach 360 ° (0 °) after passing 270 °, and the connecting rod 49 on the right side and the piston shaft 2 overlap, and the left side It will be spread in a straight line, whereby the crankshaft (51, 52) is to rotate one.

Subsequently, the power supply of the electromagnets 24 and 25 is switched by the sensor 57 which detects the right limit point of the piston 14 or the crank pins 53 and 54 so that the polarity is changed. Is moved to the left again, and all subsequent operations are performed by the piston 14 repeating the reciprocating movement by supplying power to the electromagnets 24 and 25 so that the polarities are alternated under the same process as described above. 52) will continue to rotate in one direction.

When the crankshafts 51 and 52 rotate, mechanical power is obtained, and the rotational force of the crankshafts 51 and 52 can be used as a driving source for an automobile, a generator, or various mechanical devices.

Here, the crankshaft 51 on one side is provided with a generator, and the electricity obtained from the generator 61 can be used as a motive force for the electromagnets 24 and 25.

An important feature of the present invention is to convert the magnetic force of the permanent magnet 19 to power, in the case of the internal combustion engine, once the supplied fuel is burned to obtain power, the new fuel must be continuously supplied, whereas in the present invention The power is represented by the force of the electromagnets (24, 25), and the power is obtained by adding as much force as the permanent magnet (19) having strong magnetic force, and the magnetic force of the permanent magnet (19) disappears after power generation. Instead of losing about 10% of magnetic force in 10 years, it is possible to obtain additional power over and over again. Recent developments in technology make it possible to produce permanent magnets with very large magnets, which is much more than the electrical energy input. It is possible to obtain a large amount of energy semi-permanently, which makes a great contribution to solving the energy shortage of mankind.

In particular, in the present invention, since the piston shaft reciprocates in the same direction as the interaction force between the permanent magnet and the electromagnet, the horizontal reciprocating actuation force is converted into rotational motion through the crankshaft. Can be obtained.

As described above, the present invention obtains mechanical energy due to piston movement by using repulsion and suction force of permanent magnets and electromagnets, and thus, it is possible to produce more energy at all times than electric energy, which can greatly contribute to solving the energy shortage of humankind. It works.
