The present invention relates to an engine using a permanent magnet 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 is composed of two parts called a stator and a rotor. The rotor is composed of a conductor and a magnetic body, and in most cases has a contact element called a slip or commutator.

This connects the rotor with an external circuit. 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 make a magnetic field like the rotor in addition to the housing supporting the entire motor. The arrangement determines the type and characteristics of the motor.

In understanding the principle of operation of the motor, the main rule of law is Fleming's left- and right-handed law, when a current flows through a conductor placed in a magnetic field, the force acts on the conductor. Fleming's left-hand law is the principle that the direction of the thumb perpendicular to them coincides with the direction of the force when directed to, and is 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 winding group above, and when the magnetic field produced by the primary winding moves on this secondary line, when the electromotive force is generated in the secondary winding according to Fleming's right hand law, the secondary winding creates a closed circuit. There is an electric current, like an electromotive force, that generates a force that follows Fleming's left-hand law between the rotating magnetic fields of the current and generates power by rotating the rotor. AC induction motor is basically a device with a constant rotation speed and is the most used electric device because of its simple structure and high efficiency.

In contrast, a synchronous motor, like an induction motor, is usually wound around a stator 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 around it.For example, in a two-pole synchronous motor, a direct current flows through a slip on the winding on the rotor to make one N pole and S pole ( Windings that are wound on the rotor to create a set of magnetic poles are less than field windings) .If the rotor is rotated at the same speed as the rotating field made from the 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, and the synchronous motor has the armature winding wound around the stator. It is referred to as the rotation synchronous motor to the door.

However, such motors have high efficiency in obtaining rotational power, but mechanical loss (friction or heat generation) cannot be avoided in any way, and thus output energy has to be smaller than 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) and Patent Application No. 2007-27098.

The above-mentioned applications are provided on the rotor and the stator so that the electromagnet and the permanent magnet are opposed to each other with the polarity against each other, and the power is applied through the rotating shaft rotating together with the rotor by causing the rotor to rotate by a repulsive force constantly acting between both magnets. This is how you get it.

However, the above-mentioned applications are still valid in that the driving energy obtained by using the permanent magnet power is greater than the power input to the actual electromagnet, but the electric energy is used to change the polarity of the excited electromagnet to excite the electromagnet. The need to continue to inject is followed by the constraint that the unit cannot be operated unless a pre-supplied supply of electrical energy is provided.

Accordingly, the present invention has been proposed in view of the above, and its object is to provide an engine that is reciprocally driven using only permanent magnets without requiring the supply of additional electric energy, and also for other purposes.

Reference numeral 1 denotes an engine, and the engine 1 includes a piston shaft 3 reciprocating a predetermined stroke horizontally on an upper surface of the base plate 2, and the piston shaft 3 is On the upper surface of the base plate 2, the left and right support means 3a, 3b, which are formed to face each other, are supported in a horizontally slidable manner.

In addition, the engine 1 has crank shafts 4a and 4b for converting the linear movement of the piston shaft 3 into rotational movements, and the crank shafts 4a and 4b have left and right connecting rods. 41, 42 are connected to the piston shaft 3, the piston shaft 3 and both connecting rods 41, 42 are connected by pin shafts 31, 32, the crank shaft ( 4a) and 4b and connecting rods 41 and 42 on both sides are connected by crank pins 43 and 44, respectively.

The piston shaft 3 is provided with the left and right piston heads 5a and 5b facing each other. The left and right piston heads 5a and 5b are provided with left and right support means 3a ( 3b) It is installed to reciprocate a certain stroke in a straight line with the piston shaft 3 at each inner side, and each of the left and right piston heads 5a and 5b has a polarity switching rotary shaft 6 as described later. ), The left and right reciprocating permanent magnets 51 and 52 are formed at appropriate angles in the upward and downward directions so as to correspond to each of the rotating permanent magnets 61 formed at appropriate intervals.

And the polarity switching rotary shaft 6 is installed in the middle of the left and right support means (5a) (5b) spaced apart to face each other, the upper and lower ends of the base plate 2 and the upper support plate 21 Is rotatably supported).

The rotating permanent magnets 61 are formed in stepwise multiple stages at appropriate intervals in the polarity switching rotary shaft 6, and in each step, a plurality of rotating permanent magnets 61 are formed in an isometric manner. According to the drawings of the embodiment, as shown in Figure 1, the left and right piston head (5a) (5b) and the polarity switching rotation shaft 6, respectively, left and right reciprocating permanent magnets (51) (52) and permanent rotation The magnets 61 are formed in a total of four in the up and down directions, and as shown in FIGS. 2 to 5, the polarity switching rotation shaft 6 has a hexagonal cross section, and each of the hexagon cross sections Rotating permanent magnets 61 are fixedly attached in a state buried in an isometric manner in the circumferential direction.

In addition, the left and right reciprocating permanent magnets 51 and 52 are fixed to both left and right piston heads 5a and 5b in a state in which both polarities are exposed at both ends thereof, so that the reciprocating motion of the piston shaft 3 is performed. The left and right piston heads 5a and 5b reciprocating in a straight line are reciprocated horizontally, while the polarity switching rotary shaft 6 is reciprocated every time the piston shaft 3 reciprocates once. It is configured to rotate at a set angle.

For example, when the piston shaft 3 repeats the reciprocating movement horizontally toward the left and the right, as shown in FIG. 2, the left and the right piston head 5a completes the operation movement to the left in the drawing. In this state, the left reciprocating permanent magnets 51 embedded in the left piston head 5a and the rotating permanent magnets 61 of the polarity switching rotary shaft 6 facing the magnets 51 have the same polarity. Repulsive force is generated between two permanent magnets to push each other, and when the right piston head 5b has completed the movement operation to the right in the drawing, the right reciprocating permanent magnet embedded in the right piston head 5b ( 52 and the rotating permanent magnets 61 of the polarity switching rotary shaft 6 facing the magnets 52 have different polarities, so that an attraction force is generated between the magnets on both sides, so that the left Right side The stone heads 5a and 5b are horizontally moved to the right in the drawing by the action of the repulsive force and the attractive force between the magnets facing each other, and the left and right piston heads 5a and 5b are shown in FIG. As shown in the drawing, when the movement to the right is in progress, the left reciprocating permanent magnet 51 and the rotating permanent magnet 61 facing each other have the same polarity, and the right reciprocating permanent magnet 52 and the rotating opposite thereto are Since the permanent magnets 61 have different polarities, each of the left and right piston heads 5a and 5b horizontally moves the piston shaft 3 to the left in the drawing due to the repulsive force of the magnets and the attraction force. As such, when the piston shaft 3 moves horizontally to the left in the drawing, the crank shafts 4a and 4b on both sides connected to the connecting rods 42 and 43 at both ends of the piston shaft 3 rotate to the right in the drawing. It becomes a state.

When the left and right piston heads 5a and 5b are in a state in which the movement to the left side is completed, the polarity switching rotary shaft 6 has a predetermined angle (60 ° when the rotating shaft is formed in the hexagonal cross section, or the rotating shaft is octagonal). When formed in the cross-section is rotated to 45 °), as shown in Figure 5 according to the left reciprocating permanent magnets 51 of the left reciprocating permanent magnets 51 of the left piston head (5a) corresponding to the rotating permanent magnet of the rotating shaft 6 (61) are converted to the polarity attracting the left reciprocating permanent magnets 51, and the rotating permanent magnet of the polarity switching rotary shaft (6) corresponding to the right reciprocating permanent magnets 52 of the right piston head (5b) 61 are converted to the polarity to push the right reciprocating permanent magnets 52, so that the left and right piece of cone head (5a) (5b) is horizontally moved to the right in the drawing, and As the piston shaft (3) As the horizontal movement from the left to the right, the crankshafts 4a and 4b on both sides continue to rotate to the right.

According to the present invention, the left and right reciprocating permanent magnets 51 and 52 embedded in each of the left and right piston heads 5a and 5b are formed in each of the rotating permanent magnets formed on the polarity switching rotation shaft 6. 61 are provided with intermittent rotation means 7 which have the same polarity or have different polarities.

The intermittent rotation means (7) is a step motor (71) for intermittently driving the pinion gear (62) fixed on the upper end of the polarity switching rotation shaft (6) and the drive gear (72) meshed with the pinion gear (62). In addition, the step motor 71 is the left and right piston head (5a) (5b) to reach the time to complete the horizontal movement toward the polarity switching shaft 6, left and right sensor (7a) 7b, the polarity switching rotation shaft 6 is rotated at an angle by intermittently rotating only for a time set by a control device (not shown) that controls the electricity supply by the signal. .

Further, according to the present invention, the left and right fixing plates 8a fixedly mounted on the inner surfaces of the left and right support means 3a and 3b to enhance the rotational output of both crankshafts 4a and 4b. 8b, each of the plurality of electromagnets 81 and 82 is formed at an appropriate interval up and down. Each of the electromagnets 81 and 82 is disposed on each of the left and right piston heads 3a and 3b. It is installed to correspond to the same position as the left and right reciprocating permanent magnets 51, 52 formed in the horizontal direction, and also formed in the upper and lower directions on each of the left and right fixing plates 8a and 8b. Each of the plurality of electromagnets 81 and 82 is configured such that a positive (+) (-) current is alternately applied by a power supply device (not shown). Pulling force against the reciprocating permanent magnets 51 and 52 formed in each of the left and right piston heads 3a and 3b. It is displayed by the alternately.

For example, as shown in FIG. 6, when the left piston head 5a is in the process of moving to the left toward the polarity switching shaft 6, the respective electromagnets 81 formed on the left fixing plate 8a are left pistons. While the current is supplied to have the same polarity as that of each reciprocating permanent magnet 51 formed in the head 5a, the right piston head 5b is moving to the right in a direction away from the polarity switching rotation shaft 6. At this time, the electromagnets 82 formed on the right fixing plate 8b are supplied with current so as to have a polarity attracting each reciprocating permanent magnet 82 formed on the right piston head 5b.

Therefore, the electromagnets 81 and 82 formed on the left and right fixing plates 8a and 8b as described above are left and right piston heads 5a and the respective permanent magnets embedded in the polarity switching shaft 6. The left and right reciprocating permanent magnets 51 and 52 formed in 5b) are alternately repeated to push and pull, so that each of the left and right piston heads 5a and 5b has an increased force. (3) is reciprocated, whereby the crankshaft (4a) (4b) is to generate a strong rotational output.

In addition, according to the present invention, the left and right piston heads 5a and 5b are mounted on the guide rods 9 fixed at both ends to the support means 3a and 3b on both the left and right sides. The piston head (3) is to reciprocate exactly in the horizontal direction, and also the polarity switching rotary shaft (6) can be installed in one or more on both sides with respect to the piston shaft (3), The left and right reciprocating permanent magnets 51 and 52 are formed in a plurality of lines in each of the left and right piston heads 5a and 5b according to the number of installation of the polarity switching rotary shaft 6. (See FIGS. 2-5)

On the other hand, although the present invention is not shown in the figure, a brake device is mounted on each of the output shafts of both crankshafts 4a and 4b, and the rotation operation of the crankshafts 4a and 4b is performed using the brake device. Stop or allow rotation of the crankshaft.

In order to explain the operation of the present invention configured as described above, the rotary permanent magnets 61 formed in multiple stages in the up and down directions of the polarity switching rotary shaft 6 in the engine 1 are embedded in six circumferential directions, respectively. A total of six permanent magnets 61 embedded in the circumferential direction of the stage are buried in one direction (counterclockwise direction) in a state of being buried so as to have N and S polarities as shown in FIG. A) intermittently rotating, and left and right reciprocating permanent magnets 51 and 52 formed on each of the left and right piston heads 5a and 5b are N, S of the permanent magnet as shown in FIG. It is assumed that the polarity is buried in a fixed state.

First, as shown in FIGS. 1 and 2, the left piston head 5a is moved to the left side with respect to the polarity switching rotary shaft 6 so that the left reciprocating permanent magnets 51 formed thereon are connected to the polarity switching rotary shaft 6. When the left reciprocating permanent magnet 51 and the rotating permanent magnet 61 of the polarity switching rotary shaft 6 have the same polarity while being moved to the position closest to the formed rotating permanent magnet 61 therebetween There is a repulsive force to push each other, on the contrary, the right piston head (5b) is moved to the right in the drawing, the right reciprocating permanent magnets 52 formed thereon are the most in the rotating permanent magnet (61) formed on the polarity switching shaft (6) When the right reciprocating permanent magnet 52 and the rotating permanent magnet 61 of the polarity switching rotary shaft 6 have different polarities while being moved to a distant position, they are pulled together. Manpower is generated.

Therefore, each of the left and right piston heads 5a and 5b is moved to the left side in the drawing as shown in FIG. 3 by the repulsive force and the attraction force, and thus the left and right piston heads 5a and 5b. Is moved to the left in the drawing, the piston shaft 3 is also moved to the left in the drawing, and when the piston shaft 3 is moved to the left in the drawing, the crank shafts 4a and 4b on both sides are Rotate clockwise.

4 and 5 show the polarity switching operation of the polarity switching rotary shaft 6, the illustration of FIG. 4 shows that the left and right piston heads 5a and 5b are moved to the left in the drawing. Until the point in time is reached, the repulsive force to push each other between the left piston head 5a and the polarity switching rotation shaft 6 still pulls each other between the right piston head 5b and the polarity switching rotation shaft 6. This is a state in which each is working, in this case, the intermittent rotation means (7) is operated, and accordingly the polarity switching rotary shaft (6) is rotated by a certain angle. In other words,

When the right piston head 5b reaches the point of completing the movement to the left, the right sensor 7b of the intermittent rotation means 7 senses that the left movement of the right piston head 5b is completed. The signal is sent to a control device (not shown). Subsequently, the control device receiving the signal from the right sensor 7b drives the step motor 71 of the intermittent rotation means 7 so that the drive gear 72 rotates the pinion gear 62 at an angle. The polarity switching rotary shaft 6 is rotated at an angle (60 °) set as shown in Figure 5, in this case, the reciprocating permanent magnets (51, 52) formed in the left and right piston head (5a) (5b) The polarity of each of the rotating permanent magnets 61 formed on the polarity switching rotary shaft 6 corresponding to them is changed. Accordingly, the polarity switching rotation shaft 6 pulls the left piston head 5a while the right piston head 5b is pushed out, so that the left and right piston heads 5a and 5b move to the right in the drawing. When the left and right piston heads 5a and 5b reach the point at which the movement to the right is completed, the left sensor 7a of the intermittent rotation means 7 indicates the movement state of the left piston head 5a. When it is detected, the step motor 71 is operated by the control device to rotate the pinion gear 62 at a predetermined angle. Accordingly, the polarity switching rotation shaft 6 is also rotated at a predetermined angle so that the left and right piston heads 5a ( 5b) is changed to the polarity to push out, and this operation is repeated, the piston shaft (3) along with the left and right piston head (5a) (5b) is a linear movement to move horizontally to the left and right When rotating the crankshafts 4a and 4b while repeating It will be tall.

Meanwhile, the present invention is a means for forming left and right fixing plates 8a and 8b having electromagnets 81 and 82 formed inside the left and right support means 3a and 3b, as shown in FIG. The piston shaft 3 can be reciprocated with a fast and strong force to increase the rotational speed and output of the crank shafts 4a and 4b.

Electromagnets 81 and 82 formed on the left and right fixing plates 8a and 8b are supplied in a state in which the (+) (-) poles of the current are alternately changed from the outside, thereby changing the polarity of the magnetic force. For example, as shown in FIG. 7, when a repulsive force is applied between the left piston head 5a and the polarity switching rotation shaft 6, the electromagnets 81 formed on the left fixing plate 8a are left piston heads. The attraction force pulling the reciprocating permanent magnet 51 of (5a) is to have a polarity that is applied, on the contrary, each of the electromagnets 82 formed on the right fixing plate (8b) is a reciprocating permanent magnet formed on the right piston head (5b) 52, and the repulsive force is applied to push them, and thus the electromagnets 81 and 82 formed in the left and right fixing plates 8a and 8b are thus left and right piston heads 5a and 5b. As power is moved to the left and right, power is supplied so that the polarity is alternately changed.

Accordingly, the left and right piston heads 5a and 5b are magnetic energy of the rotating permanent magnet 61 of the polarity switching rotary shaft 6 and the electromagnets 81 provided on the left and right fixing plates 8a and 8b, respectively. The piston shaft 3 rotates the crankshafts 4a and 4b in a fast and strong linear motion as the reciprocating movements to the left and the right by the magnetic energy of the 82 causes the crankshaft to have an enhanced rotational output. To be generated.

Meanwhile, in the present invention, as the left and right piston heads 5a and 5b reciprocate to the left and right sides, the intermittent rotation means 7 which repeatedly rotates the polarity switching rotation shaft 6 by a predetermined angle step motor 71. ) And a sensor, etc. have been described as an embodiment, but the intermittent rotation means 7 is not limited to the same structure as the step motor 71, and the left and right piston heads 5a and 5b are moved left and right. If the structure that can rotate the polarity switching rotation shaft 6 by a predetermined angle every time it moves, all are satisfied.

According to the present invention as described above by using the semi-permanent magnetic energy of the permanent magnet can obtain mechanical energy to reciprocate the piston shaft, and also by providing an engine that can obtain a stronger rotational power than the electrical energy supplied to the electromagnet The solution of energy shortages can contribute greatly.
