BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for generating energy using a low-

[0001] The present invention relates to an energy generating device using a helix array, and more particularly, to an energy generating device using a helix array capable of improving energy conversion efficiency by interaction of a magnetic field generated by a plurality of magnets To an energy-generating device using the same.

Generally, energy generating devices are electric machines in the form of generators, where the main source of energy is used to rotate the object, and the rotor and stator cooperate to generate energy. Electric machines in the form of generators include self-propelled devices, pumps, electric motors and generators. At this time, the electric motors and generators operate at predetermined speed and power conditions. However, as the rotational speed and the power output of the electric motor and the generator increase, the energy conversion efficiency in which the input energy of the electric motor and the generator is converted into the output energy is very low. For reference, the energy conversion efficiency, which is the output energy ratio of the generator compared to the input energy required for operation of the turbine or the prime mover, is about 35%.

The above-described generator includes a cylindrical stator and a rotor. That is, the generator is provided with a stator, which is a stator, and a rotor, which is a rotor, and is formed in such a manner that the rotor rotates to induce an electromotive force. At this time, a current flows through the armature coil of the generator to generate a counter electromotive force that hinders rotation or movement of the rotor, and the rotational speed of the rotor is reduced by the generated counter electromotive force.

In order to minimize the energy loss due to the back electromotive force caused by the structural characteristics of the generator, researches for improving the conversion efficiency of the output energy to the input energy have been actively conducted. However, the research on the improvement of the conversion efficiency of such a generator does not generate the rotation motion which is the basis of the generator itself without external power, so that more energy is supplied to the rotor of the generator so that the rotation speed of the rotor is not decreased The energy conversion efficiency in which the input energy is converted into the output energy is not greatly improved.

Accordingly, the present applicant has proposed the present invention in order to solve the above problems, and related prior art documents include Korean Patent Application Publication No. 10-2009-0045699 (published on May 05, 2009). ).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apparatus 100 for generating energy according to an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG.

1 to 4, an energy generating apparatus 100 using a harmonic arrangement according to an embodiment of the present invention includes an internal magnetic force unit 112 having a plurality of magnets arranged in a Halbach array, A magnetic force part 110 including an external magnetic force part 114 having a plurality of magnets arranged in a Halbach array so as to have different magnetic field directions from the internal magnetic force part 112; And a controller 130 for controlling the driving of the motor 120. [0031]

1 to 4, the magnetic force unit 110 may include an internal magnetic force unit 112 and an external magnetic force unit 114. The internal magnetic force part 112 may be provided with a plurality of magnets arranged in an obverse array. At this time, a plurality of magnets provided in the form of a helix arrangement of the internal magnetic force part 112 may be formed of a rare earth permanent magnet having strong magnetism. Specifically, the internal magnetic force part 112 is provided in a circular shape having a central axis, and may be formed in a ring shape. Since the internal magnetic force part 112 is formed in a circular ring shape, a plurality of magnets constituting the internal magnetic force part 112 may also be provided in a circular shape. In the Halbach arrangement, the magnetic field of the permanent magnet is superimposed on one side of the magnet to form a strengthened magnetic field. On the other side of the magnet, the magnetic field is almost '0' due to the canceling effect of the magnetic field distribution of the permanent magnet. A permanent magnet array is formed.

The external magnetic force part 114 is positioned so as to surround the outer circumferential surface of the internal magnetic force part 112, and a plurality of magnets may be provided in the form of a whorl arrangement. At this time, a plurality of magnets provided in the form of a helix arrangement of the external magnetic force part 114 may be provided as rare earth permanent magnets having strong magnetism.

Here, the plurality of magnets of the external magnetic force part 114 should be arranged so as to have different directions from the magnetic field directions of the plurality of magnets of the internal magnetic force part 112. For example, if the magnetization directions of a plurality of magnets formed in the internal magnetic force part 112 are arranged in a counterclockwise direction, a plurality of magnets formed in the external magnetic force part 114 should be arranged so that the magnetization directions proceed clockwise do. As shown in Fig. 4, the permanent magnets constituting the internal magnetic force part 112 and the external magnetic force part 114 can be arranged so as to have a magnetization direction.

Accordingly, when the internal magnetic force part 112 and the external magnetic force part 114 formed by arranging the plurality of permanent magnets in a hoop arrangement are rotated, a force or repulsion torque is applied between the internal magnetic force part 112 and the external magnetic force part 114 . The energy generating apparatus 100 using the helix arrangement according to an embodiment of the present invention may use the repulsive torque generated between the internal magnetic force unit 112 and the external magnetic force unit 114 to generate the internal magnetic force unit 112 or When the energy input to the internal magnetic force unit 112 and the external magnetic force unit 114 is converted into output energy because the external magnetic force unit 114 generates energy by rotating the external magnetic force unit 114 and reduces the input energy required to generate energy, Can be improved.

On the other hand, it is very difficult to form a plurality of permanent magnets of the internal magnetic force part 112 and the external magnetic force part 114 in the form of a helix array so as to be capable of continuous magnetic field conversion. Therefore, it is preferable to manufacture the permanent magnets 112 by separating them into permanent magnets in the form of a finite number of constituent grids of the internal magnetic force portion 112 or the external magnetic force portion 114. At this time, if the number of permanent magnets forming the internal magnetic force part 112 and the external magnetic force part 114 increases, a sinusoidal wave generated by the magnetic field of the internal magnetic force part 112 and the external magnetic force part 114 (Torque waveform) can be approximated to a complete sinusoidal waveform. Here, a sinusoidal wave refers to a waveform of the most basic form by AC power. In other words, since it is difficult to infinitely increase the number of permanent magnets of the internal magnetic force part 112 and the external magnetic force part 114 formed by the helix arrangement, the number of the permanent magnets forming the helix arrangement and the angle of the magnetization direction, The energy generation apparatus 100 may be configured to generate energy using the heavily array according to an embodiment of the present invention.

The magnetic force unit 110 may be provided as a rotor or a stator. In other words, either the internal magnetic force unit 112 or the external magnetic force unit 114 may be a stator or a rotor. If the internal magnetic force part 112 is a stator, the external magnetic force part 114 is a rotor and if the external magnetic force part 114 is a stator, the internal magnetic force part 112 is a rotor rotor. Meanwhile, in the energy generating apparatus 100 using the helix arrangement according to an embodiment of the present invention, the internal magnetic force unit 112 is formed as a rotor, the external magnetic force unit 114 is formed as a stator, The external magnetic force part 114 can freely rotate about the periphery.

The internal magnetic force part 112 and the external magnetic force part 114 may be formed to have the same center axis M as shown in FIG. Accordingly, the internal magnetic force part 112 and the external magnetic force part 114 having the same central axis M can rotate clockwise or counterclockwise by the driving of the motor 120, which will be described later.

In addition, a gap L may be formed between the internal magnetic force part 112 and the external magnetic force part 114. The gap between the internal magnetic force part 112 and the external magnetic force part 114 is formed at an interval where the rebound torque value between the internal magnetic force part 112 and the external magnetic force part 114 is maximized, Size should be considered. The gap formed between the internal magnetic force part 112 and the external magnetic force part 114 serves to maximize the repulsive torque due to the magnetic field between the internal magnetic force part 112 and the external magnetic force part 114. [ That is, an air gap L of an appropriate size is formed between the internal magnetic force part 112 and the external magnetic force part 114 so as to maximize the repulsive torque, and an internal magnetic force part having a magnetization direction 112 and the external magnetic force part 114 are rotated by the internal magnetic force part 112 and the external magnetic force part 114 connected to the same central axis and the magnetic field of the internal magnetic force part 112 and the external magnetic field generated by the external magnetic force part 114 The magnetic fields interact with each other and the repulsive torque of the sinusoidal wave can be generated by the phase difference between the magnetic fields of the internal magnetic force part 112 and the external magnetic force part 114. [

The motor 120 may be connected to the center axis of the magnetic force unit 110 to rotate the magnetic force unit 110. Specifically, the motor 120 may be connected to the magnetic force part 110, that is, the center axis M of the internal magnetic force part 112 and the external magnetic force part 114. The internal magnetic force unit 112 or the external magnetic force unit 114 can be rotated by the motor 120 that receives the external input power and rotates. At this time, the motor 120 may be a motor of a commonly used type, but a motor having a small cogging torque so as not to act as a resistance element when the magnetic force part 110 is rotated is preferable. Here, the motor 120 is not for continuously rotating at least one of the internal magnetic force unit 112 and the external magnetic force unit 114, and at least one of the internal magnetic force unit 112 and the external magnetic force unit 114 may be a And is rotated by the torque (force) generated due to the magnetic field characteristic by the arrangement. As will be described later, the motor 120 is a means for assisting the rotational motion of the internal magnetic force portion 112 or the external magnetic force portion 114.

If the motor 120 is provided at one end of the center axis M of the magnetic force unit 110, the generator 140 may be provided at the other end of the center axis M of the magnetic force unit 110. That is, when the motor 120 is connected to one end of the internal magnetic force part 112, the generator 140 may be connected to the other end of the internal magnetic force part 112.

The generator 140 can be used as a power source of rotational force generated by the repulsive torque generated by the magnetic force unit 110. [ In other words, the generator 140 can be driven by the rotational torque of the internal magnetic force portion 112 or the external magnetic force portion 114 due to the drive torque input to the motor 120. [ As described above, a large amount of torque can be generated due to a small amount of torque for driving the magnetic force unit 110, or a repulsive torque between the internal magnetic force unit 112 and the external magnetic force unit 114 . The generator 140 may be a conventional generator, but the generator 140 according to an embodiment of the present invention may be an alternator. Since the generator 140 is provided in the energy generating apparatus 100 using the Habakkuk arrangement, it can be applied to manual power generation.

The apparatus 100 for generating energy using the Habakkuk arrangement according to an embodiment of the present invention may further include an inverter 150. The inverter 150 can convert the input AC power into DC power. Specifically, the inverter 150 engages with the generator 140, and receives power generated by the generator 140 and converts the AC power to DC power.

In addition, the energy generation apparatus 100 using the Habakkuk arrangement according to an exemplary embodiment of the present invention may further include a battery 160. FIG. The battery 160 can store the DC power converted by the inverter 150. [ That is, since the storage battery is provided in the energy generating apparatus 100 using the Habakkuk arrangement, the stored power can be conveniently used whenever necessary.

The controller 130 can control the driving of the motor 120. [ In other words, the controller 130 can control the motor 120 for driving the internal magnetic force part 112 and the external magnetic force part 114. [ Specifically, the controller 130 determines whether the magnetic force part 110 is repeatedly moved from the unstable equilibrium point at the initial position A to the end position A 'that is the other unstable equilibrium point via the stable equilibrium point at the intermediate position B on the sinusoidal wave The motor 120 may be controlled to move to the second position. Here, the intermediate position (B) means a position which is a '0' point on the sinusoidal wave.

Hereinafter, the control algorithm of the controller 130 will be described in detail.

The controller 130 can control the motor 120 with a separate control algorithm. Specifically, the controller 130 controls the motor 120 so that the magnetic force unit 110 generates an initial position A (see FIG. 1) where the magnetic field of the internal magnetic force unit 112 and the external magnetic force unit 114 are the same polarity, ) At an unstable equilibrium point. That is, the controller 130 can control the motor 120 with the TPBVP (Two Point Boundary Value Problem) optimal control algorithm to position the magnetic force unit 110 at the initial position A. At this time, the TPBVP optimal control algorithm refers to a control method that minimizes energy. Specifically, the TPBVP optimal control algorithm is a method of calculating the control input that minimizes energy while satisfying the constraint. The controller 130 having such a control scheme can be implemented by the following equations.

The controller 130 can place the initial position A of the magnetic force unit 110 at the unstable equilibrium point with the TPBVP optimal control algorithm implemented by the above equation. The initial position A of the magnetic force unit 110 is located at the unstable equilibrium point to realize switching control using the unstable potential energy of the unstable equilibrium point. In this case, the switching control using the unstable position energy can obtain the optimum torque required for switching the unstable equilibrium point of the pendulum, that is, the magnetic force unit 110 from the initial position A by one turn, through the TPVBP optimal control algorithm have.

As shown in FIG. 5, when the switching control using the position energy is started, the magnetic force unit 110 is located at the unstable equilibrium point on the sinusoidal wave by the TPVBP optimal control algorithm and has the maximum potential energy. Here, when the magnetic force part 110 is located at the initial position A, the controller 130 can rotate the magnetic force part 110 by controlling the motor 120 with the TPBVP optimum control algorithm. Accordingly, the magnetic force unit 110 passes through the stable equilibrium point, which is the intermediate position B having the lowest potential energy at the unstable equilibrium point having the maximum potential energy, A '). ≪ / RTI >

The internal magnetic force part 112, which is a rotor of the magnetic force part 110, is positioned at an unstable equilibrium point on the sinusoidal wave by the TPBVP optimal control algorithm of the controller 130 and the internal magnetic force part 112, So that the rotational force can be applied from the motor 120.

The controller 130 instructs the motor 120 to drive the internal magnetic force part 112 by the TPVBP optimal control algorithm after the internal magnetic force part 112 is moved to the unstable equilibrium point at the initial position A, Can be controlled to be applied. At this time, the drive torque applied to the internal magnetic force part 112 means a small amount of torque. It is possible if the internal magnetic force part 112 has a torque amount enough to deviate from the position of the unstable equilibrium point. That is, the amount of torque input to the motor 120 is sufficient for a small amount of torque to be able to rotate the internal magnetic force part 112, so that it is not necessary to input a large drive torque. Accordingly, the energy for driving the motor 120 can be minimized, and the amount of energy required for driving the internal magnetic force part 112 can be minimized.

The period of the rotation cycle of the internal magnetic force part 112 to which the small amount of torque is applied may be varied depending on the field to which the energy generating device 100 according to the embodiment of the present invention is applied. Here, one period of the rotation cycle of the internal magnetic force part 112 is the end point of the internal magnetic force part 112 to which the internal magnetic force part 112 to which a small amount of torque is applied passes through the stable equilibrium point at the intermediate position B at the unstable equilibrium point, Is moved to another unstable equilibrium point at position A '. When the internal magnetic force part 112 rotates 360 degrees in order to rotate from the initial position A to the end position A ', the internal magnetic force part 112 is substantially held by the various friction elements, It is impossible to rotate 360 degrees by only the driving torque of the motor. Accordingly, there is a point at which the speed of the internal magnetic force part 112 becomes '0' before the internal magnetic force part 112 rotates 360 degrees completely. If no torque is applied to the internal magnetic force part 112, the unstable ball point at the initial position A is changed from the unstable ball point at the end position ((A)) by the unstable repulsive torque generated between the internal magnetic field part 112 and the external magnetic field part 114 A ') but can not be located at the other unstable equilibrium point, but is retracted to the stable equilibrium point at the intermediate position (B). At this time, the controller 130 may control the motor 120 by a linear quadratic cascadic control (LQ) algorithm, which is a linear control algorithm, to place the internal magnetic force part 112 at the switching end point A '. Here, the LQ control algorithm of the controller 130 means an energy control method using linear control. Specifically, the control method of the controller 130 having the LQ control algorithm will be described below.

The internal magnetic force part 112 and the external magnetic force part 114 which are aligned at the initial stable equilibrium point of the system are separated to separate the internal magnetic force part 112 from the stable equilibrium point B to the unstable equilibrium point A ' The energy control method of the swing-up can be applied in order to start the rotation to the point. That is, a control signal is generated so that the potential energy of the internal magnetic force part 112 of the obverse array becomes '0'. For the above-described swing-up control

The energy of the system can be selected as a function of the Lyapunov and the controller 130 can be designed using the following equation.

J represents the inertia of the internal magnetic field portion itself having a Habakkuk arrangement and the inertia of the external magnetic field portion connected to the internal magnetic field portion concentrically with the internal magnetic field portion, And To is a coefficient of the repulsive torque generated in accordance with the relative displacement between the internal magnetic force portion and the external magnetic force portion, and τ is the input torque to the internal magnetic force portion.

In Equation (5), the control signal u is determined by the angle, angular velocity and energy difference with respect to the initial position, and the magnitude of the control input is determined by a constant k.

If the internal magnetic force part 112 comes near the unstable equilibrium point by the torque inputted as described above, the magnetic force part 110 is switched to the LQ control algorithm of the linear control method and the unstable equilibrium point . The state equations for applying the LQ control algorithm are as follows. At this time, the model of the Habakkuk arrangement is linearized with respect to the small displacement near the equilibrium point, and the Coulomb friction is neglected.

Equation (6) represents a system equation, Q is a weight for a position error of a magnetic force part, and R is a weight for an input torque.

The value by the LQ control algorithm of the controller 130 can be derived through the following matlab command.

K = lqr (A, B, Q, R)

That is, when the rotational speed of the internal magnetic force part 112 becomes '0', the controller 130 causes the internal magnetic force part 112 to be moved to the unstable equilibrium point of the initial position A by using the motor 120 And the torque is applied to the internal magnetic force part 112 by controlling the motor 120 by the LQ control algorithm. The rotation of the internal magnetic force part 112 can be infinitely repeated by the control of the controller 130. [

As described above, since energy for driving the magnetic field unit 110 is generated only by a small amount of initial driving torque, the conventional energy generating apparatus 100 using the jerky arrangement according to an embodiment of the present invention generates energy It is possible to obtain an energy conversion efficiency higher than that of the device.

Also, since the energy generating apparatus 100 using the hoop arrangement according to an embodiment of the present invention can obtain the energy required to rotate the internal magnetic force unit 112 only with a small amount of initial starting torque, have.

The energy generation apparatus 100 using the heuristic array according to an exemplary embodiment of the present invention may further include an inverter 150 and an accumulator 160 for generating energy (or power) generated from the magnetic force unit 110 and the generator 140, Can be used to convert or store energy.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. will be.

Therefore, it should be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
