Description

MAGNETIC LEVITATION SYSTEM HAVING HALBACH ARRAY}

The present invention relates to a magnetic levitation system and more particularly to a magnetic levitation system having a Halbach arrangement.

Maglev train refers to a train that floats and propels to a certain height from the track using electric magnetic force. Maglev trains include a trolley that floats and propels on a track, and a vehicle body mounted on the trolley to form a carriage or wagon.

The magnetic levitation train propels the trolley away from the track by applying an attractive force or repulsion force by an electromagnet between the trolley and the track. In this way, the magnetic levitation train is propelled in a non-contact state with the track, so the noise and vibration is low and high speed propulsion is possible.

The floating method of the magnetic levitation train includes a suction method using the attraction force of the magnet and a reaction method using the repulsive force of the magnet.

In addition, the floating method of the magnetic levitation train has a superconducting method and a phase conducting method according to the principle of the electromagnet. The superconducting method is applied to high speed trains because there is no electric resistance and strong magnetic force can be obtained, and the phase conduction method is applied to medium speed stop trains.

Reaction type includes permanent magnet repulsion using repulsive force acting between permanent magnets of the same pole, and inductive repulsion floating by magnetic field repulsive force caused by induced current of ground coil induced by movement of magnet attached to vehicle. Repulsion is easier to control than recognition, and suction has the advantage that it can be injured even at low speeds.

In particular, the inductive repulsion is not sensitive to changes in load and is suitable for ultra-high speeds. The magnet of the vehicle uses a superconducting magnet and requires a very low temperature for superconducting.

As such, a high-speed magnetic levitation method is typically researched in Germany using a phase conduction suction formula, and in Japan, a research is being conducted based on a superconducting repulsion formula.

Both suction and repulsion are generating flotation by using an electromagnet, but in order to obtain a desired flotation force, the volume of the electromagnet must be large, and accordingly, power consumption is large.

On the other hand, a magnetic levitation system that floats by rotating a magnet on a conductor plate without using a track has been proposed, and this levitation system utilizes a magnetic induction phenomenon by rotation of a rotating permanent magnet or an electromagnet. In order to efficiently generate magnetic induction on the conductor plate, magnetic force lines must be distributed in the up or down direction.

However, as shown in FIG. 8, the conventional permanent magnet rotor acts in the lateral direction, which is a closer direction than the magnetic force is distributed in the vertical direction, so that the magnetic force induction acting on the conductor plate is insignificant compared to the magnetic force. Accordingly, a strong magnetic force and a strong rotational force are required for the injury, and the consumption of energy for the injury is excessively large.

In addition, when the motor is used to rotate the rotor, the permanent magnet or electromagnet of the motor is affected by the rotor having a strong magnetic force causes a problem that the motor does not operate properly. In order to solve this problem, a member for shielding a magnetic force must be provided between the rotor and the motor, but the member for shielding the magnetic force is expensive, and thus, a manufacturing cost increases.

The present invention has been made to solve the above problems, an object of the present invention is to provide a magnetic levitation system with improved efficiency.

The magnetic levitation system according to an aspect of the present invention includes a conductor plate fixed on the ground, and a permanent magnet module located on the conductor plate and having a halbach array and a motor for rotating the permanent magnet module.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

1 is a plan view of a magnetic levitation system according to a first embodiment of the present invention, Figure 2 is a cross-sectional view taken along the line II-II in FIG.

Referring to FIGS. 1 and 2, the magnetic levitation system 100 according to the present exemplary embodiment includes a bogie 120 and a bottom plate 150 positioned below the bogie 120. Bogie 120 is a floating operation, and includes a lower support plate 123 and the mounting member 121 is fixed to the lower support plate 123.

The loading member 121 according to the present embodiment may be formed in a plate shape, but the present invention is not limited thereto, and the loading member 121 may have a vehicle structure in which a passenger or cargo may be mounted. The lower support plate 123 and the stacking member 121 are fixed through the support rod 125, and two support rods 125 are installed at the corner portions. The support rod 125 may have a structure in which an elastic member such as a spring is installed therein to cushion the impact.

The bogie 120 according to the present embodiment is placed on the bottom plate 150 or floats from the bottom plate 150, and the bogie 120 has a permanent magnet module 140 and a permanent magnet having a Halbach arrangement. And an electric motor 131 for rotating the module 140.

As shown in FIG. 2 and FIG. 3, the electric motor 131 is fixed to the loading member 121, and the driving gear 132 is installed to the electric motor 131. The permanent magnet module 140 has a driven gear 134 coupled to the drive gear 132 is installed. The driving gear 132 and the driven gear 134 may be formed of a spur gear, and may be formed of various types of gears in addition to the spur gear.

When the electric motor 131 and the permanent magnet module 140 is connected and installed through the gears 132 and 134 as in the present embodiment, the motor 131 is not installed directly above the permanent magnet module 140 and is offset. Since it is installed on the upper side, it is possible to prevent the motor 131 from malfunctioning due to the magnetic force generated from the permanent magnet module 140.

Since the permanent magnet module 140 has a strong magnetic force may affect the peripheral devices. In particular, since the rotor of the electric motor 131 is made of a magnet is affected by the permanent magnet module 140 a lot. When the rotor of the electric motor 131 is pushed or pulled by the permanent magnet module 140, the friction increases during rotation, so that the rotation force may not be properly generated or the motor 131 may be damaged due to the friction. However, since the electric motor 131 and the permanent magnet module 140 are connected through the gears 132 and 134, the electric motor 131 may be installed away from the permanent magnet module 140 to reduce the malfunction of the motor 131. In addition, it is possible to control the rotation of the permanent magnet module 140.

Meanwhile, the driven gear 134 is connected to the permanent magnet module 140 via the bearing 135. Bearing 135 is made of a cross-roller bearing that can stably support the axial load of the top plate.

The bearing 135 is fitted to the lower support plate 123 and is fixedly installed. The bearing 135 has a shaft 136 and a permanent magnet module 140 coupled to the shaft 136. Accordingly, the permanent magnet module 140 is fixed to the lower support plate 123 via a bearing and may be rotated at a set speed by receiving power from the electric motor 131. On the other hand, the lower support plate 123 is provided with an auxiliary wheel 137 to be movable when the injury is stopped.

The bottom plate 150 is installed below the cart 120, and the bottom plate 150 includes a conductor plate 151 and a ferromagnetic body plate 152 positioned below the conductor plate 151. The conductor plate 151 is installed to cover the ferromagnetic plate 152. At this time, the conductor plate 151 is made of aluminum or aluminum alloy, the ferromagnetic body plate 152 may be made of iron, nickel cobalt or an alloy thereof having a greater magnetic than aluminum when a strong magnetic field is applied from the outside. .

 When the ferromagnetic body plate 152 is installed to cover the conductor plate 151 made of aluminum or an aluminum alloy as in the embodiment, a larger eddy current can be formed in the conductor plate 151, thereby generating a greater floating force. Done.

Although the conductor plate 151 is illustrated as being made of aluminum or an aluminum alloy in the present embodiment, the present invention is not limited thereto, and the conductor plate 151 may be made of metal of various materials.

As shown in FIG. 1, the permanent magnet module is installed at four corners of the lower support plate 123, and four electric motors 131 are installed on the loading member to rotate each permanent magnet module 140.

Permanent magnet module 140 is formed in a ring shape having a Halbach array (Halbach array). The Halbach array, first proposed by Klaus Halbach in 1979, combines multiple permanent magnet pieces to generate the magnetic field distribution required by the motor system.

As shown in FIG. 4, the permanent magnet module 140 includes a plurality of permanent magnet pieces, and the magnetization directions of the permanent magnet pieces are arranged to change in the vertical direction. In the present description, the magnetization direction is changed in the vertical direction to mean that the magnetization direction of the permanent magnet pieces constituting the permanent magnet module is different.

The permanent magnet module 140 includes guide magnet pieces 143, 144, and 145 disposed between the magnetic pole pieces 141 and 142 and the magnetic pole pieces 141 and 142. The magnetic pole magnet pieces 141 and 142 and the guide magnet pieces 143, 144 and 145 are arranged to extend in the circumferential direction of the permanent magnet module 140. Accordingly, the permanent magnet module 140 forms a substantially circular ring shape.

The first magnetic pole magnet piece 141 has a magnetization direction facing downward, and the second magnetic pole magnet piece 142 has a magnetization direction pointing upward. Accordingly, the first magnetic pole magnet piece 141 emits magnetic force lines downward and the second magnetic pole magnet piece 142 emits magnetic force lines upward. The guide magnet pieces 143, 144, and 145 serve to guide the lines of magnetic force, and are arranged such that the magnetization direction gradually changes from the second magnetic pole magnet piece 142 to the first magnetic pole magnet piece 141. The guide magnet pieces 143, 143, and 144 move the lines of magnetic force emitted from the second magnetic pole magnet piece 142 to the first magnetic pole magnet pieces 141, whereby the lines of magnetic force extending upward do not become dense and spread. The magnetic field lines going downward are concentrated. The permanent magnet module 140 may be formed by dividing the permanent magnet having a constant magnetization direction into several pieces, and then combining them.

Permanent magnet module 140 according to this embodiment is made of a ring shape, but the magnetization direction is not changed in the circumferential direction, but the magnetization direction is changed in the circumferential direction, so the permanent magnet module 140 is the strength of the magnetic field formed on the top The magnetic field formed in the lower part can be concentrated while minimizing. Therefore, the magnetic field of the permanent magnet module 140 can be concentrated in the downward direction to obtain a greater floating force than the existing permanent magnet.

When the permanent magnet module 140 rotates, an electric field is induced by Faraday's law, and a current is generated in the conductor plate 151 due to the induced electric field. That is, an electromotive force is formed to interfere with the change of the magnetic field of the magnet in the direction in which the permanent magnet module 140 moves, and this electromotive force generates an eddy current in the conductor plate 151. The intensity of the eddy current is proportional to the conductivity of the conductor plate 151, the moving speed of the permanent magnet module 140, and the magnitude of the magnetic flux density in the normal direction.

As shown in FIG. 8, the conventional permanent magnet is composed of two or four magnetic pole magnet pieces, and the magnetic force moves or spreads in a horizontal direction with a magnet located sideways rather than being concentrated downward. Accordingly, the influence on the conductor plate is smaller than that of the magnetic force, so that the strength of the eddy current is not large.

However, if the permanent magnet module has a Halbach array as in this embodiment, the magnetic flux density in the normal direction increases by 1.4 times or more, thereby generating a larger eddy current. When an eddy current occurs, a magnetic force called Lorentz's force is generated, and the vertical component of the magnetic force acts as a floating force.

In addition to the floating force generated by the Lorentz force, the resistance is also generated, the drag force (drag-force) refers to the force acting in the direction opposite to the rotation direction of the permanent magnet module 140. Resistance is large at low speeds, but decreases with increasing speed, and flotation increases with increasing speed. In this embodiment, the resistive force is generated in the rotational direction of the permanent magnet module 140, not the direction in which the bogie 120 moves, and the permanent magnet module 140 rotates at a high speed by the electric motor 131. The resistivity can be minimized compared to the Bach arrangement.

As described above, according to the present embodiment, a large floating force may be generated by using the permanent magnet module 140 having a Halbach arrangement, and thus, power consumption for injuries may be significantly reduced as compared to a conventional magnetic levitation system. .

In the present embodiment, the permanent magnet module 140 is illustrated as being composed of a Halbach array of eight elements, but the present invention is not limited thereto.

5 is a perspective view illustrating a permanent magnet module 160 according to a modification of the first embodiment.

Referring to FIG. 5, the permanent magnet module 160 according to the present embodiment includes a guide magnet piece 163 disposed between four magnetic pole pieces 161 and 162 and magnetic pole pieces 161 and 162. Include. The magnetic pole magnet pieces 161 and 162 and the guide magnet piece 163 are arranged to extend in the circumferential direction of the permanent magnet module 160. Accordingly, the permanent magnet module 160 has a substantially circular ring shape.

The first magnetic pole magnet piece 161 emits magnetic force lines upward, and the second magnetic pole magnet piece 162 emits magnetic force lines downward. The guide magnet pieces 163 serve to guide the lines of magnetic force, and the magnetization direction is a direction from the first magnetic pole magnet piece 161 toward the second magnetic pole magnet piece 162. Accordingly, the guide magnet pieces 163 move the line of magnetic force emitted from the first magnetic pole magnet piece 161 to the second magnetic pole magnet piece 162. Therefore, the lines of magnetic force going upward are not concentrated and spread, but the lines of magnetic force going downward are concentrated. The permanent magnet module 160 may be formed by dividing the permanent magnet having a constant magnetization direction into several pieces and then combining them.

The permanent magnet module 160 according to the present embodiment may compact the magnetic field formed at the bottom while minimizing the strength of the magnetic field formed at the top. Therefore, the magnetic field of the permanent magnet module 160 is concentrated in the downward direction can obtain a greater flotation force than the existing permanent magnet.

6 is a plan view illustrating a magnetic levitation system according to a second exemplary embodiment of the present invention, and FIG. 7 is a cross-sectional view taken along the line VII-VII of FIG. 6.

Referring to FIGS. 6 and 7, the magnetic levitation system 200 according to the present exemplary embodiment includes a bogie 220 and a bottom plate 250 positioned below the bogie 220. The trolley 220 includes a loading member 221 fixed to the lower support plate 223 and the lower support plate 223 to operate in a floating manner.

The loading member 221 according to the present embodiment may be formed in a plate shape, but the present invention is not limited thereto, and the loading member 221 may be formed in a vehicle structure in which a passenger or cargo may be mounted. The lower support plate 223 and the loading member 221 are fixed through the support rod 225, and two support rods 225 are installed at the corner portions.

The bogie 220 according to the present embodiment is placed on the bottom plate 250 or floats from the bottom plate 250 to move, and the bogie 220 has a permanent magnet module 240 having a Halbach arrangement. It includes an electric motor 231, a linear motor 260 to rotate the permanent magnet module 240.

The motor 231 is fixedly installed on the loading member 221, the drive gear 232 is installed on the motor 231, the driven gear 234 coupled to the drive gear 232 is connected to the permanent magnet module 240 is connected. It is installed.

The driven gear 234 is connected to the permanent magnet module 240 via the bearing 235. The bearing consists of a cross-roller bearing capable of stably supporting the axial load of the upper plate.

The bearing 235 is fitted to the lower support plate 223, and a shaft 236 and a permanent magnet module 240 coupled to the shaft 236 are installed below the bearing 235. Accordingly, the permanent magnet module 240 may rotate at a set speed by receiving power from the electric motor 231. On the other hand, the lower support plate 223 is provided with an auxiliary wheel 237 to be movable when the injury is stopped. The bottom plate 250 includes a conductor plate 251 and a ferromagnetic plate 252 positioned below the conductor plate 251.

Since the linear motor 260 is installed to face the conductor plate 251, when the linear motor 260 moves, a magnetic flux moving in time and space occurs to generate an eddy current in the conductor plate 251. The propulsion force is generated by the interaction of the eddy current and the pore flux by the Lorentz force equation. When the linear induction motor is applied as in the present embodiment, propulsion force can be generated by the action of the flat plate-shaped conductor plate.
