Magnetic levitation propulsion refers to the propulsion of levitated at a constant height from the orbit using electric magnetic force. Magnetic levitation systems include bogies that float and propel in non-contact on orbits and orbits.
The magnetic levitation system applies the attractive force or the repulsive force by the electromagnet between the bogie and the orbit to propel the bogie away from the orbit. As described above, the magnetic levitation system is driven in a non-contact state with the orbit, so that it is possible to carry out the high speed propulsion with less noise and vibration.
In the magnetic levitation method, there are a suction type using the attractive force of the magnet and a repulsive type using the repulsive force of the magnet. In addition, there are a superconducting system and a superconducting system in accordance with the principle of electromagnetism in the method of levitation of the magnetic levitation. The superconducting method is applied to high speed train because it has no electric resistance and strong magnetic force, and the phase transfer method is applied to the medium speed long distance train.
In a magnetic levitation system, the levitation force is determined by the amount of current flowing through the levitation electromagnet. However, if the amount of electric current flowing in the floating electromagnet having a relatively large magnetic force is changed, the variation of the levitation force becomes large, and the interval between the bogie and the orbit becomes large. Accordingly, there is a problem that it is difficult to finely control the interval between the bogie and the orbit.

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 longitudinal sectional view of a magnetic levitation system according to a first embodiment of the present invention, which is cut in a width direction.
1, the magnetic levitation system 101 according to the present embodiment includes a bogie 120 moving by magnetic force and a trajectory 110 installed at the bottom of the bogie.
The carriage 120 is formed in the shape of a rectangular plate, and is lifted from the ground by magnetic force and moves. A first ferromagnetic plate 121 and a second ferromagnetic plate 122 are fixed to the upper surface of the carriage 120 and a metal plate 123 is provided on a side surface of the carriage 120. A plurality of permanent magnets 124 are provided on the lower surface of the truck 120. The permanent magnets 124 are arranged along the traveling direction of the bogie 120 and are arranged so that different poles are adjacent to each other.
A support frame 112 is installed on the carriage 120 and the support frame 112 is fixed to the base 160. The base 160 may be made of paper, artificially formed bedrock or plant installed equipment.
The support frame 112 includes an upper frame 112a disposed parallel to the bogie 120 and side frames 112b and 112c formed to extend toward the track 110 at both ends of the upper frame 112a. A floating electromagnet 141 and an air gap fine adjustment electromagnet 142 are fixedly mounted on the support frame 112. Two floating electromagnets 141 and two air gap fine adjustment electromagnets 142 are provided in the support frame 112. The floating electromagnets 141 and the gap fine adjustment electromagnets 142 are disposed on both sides of the upper frame 112a . The floating electromagnet 141 is installed in the upper frame 112a via the fixing member 131. [
The guide electromagnets 151 are installed on the inner side surfaces of the side frames 112b and 112c. The guide electromagnets 151 include a core 151a and a coil 151b surrounding the core 151a. The guide electromagnet 151 is installed on the side frames 112b and 112c via a fixing member 132 and has a structure in which two guide electromagnets 151 are symmetrical. The electromagnet 151 is arranged to face the metal plate 123 provided on the carriage 120 and pulls the metal plate 123 to control the carriage 120 to be positioned at the center in the widthwise direction of the track 110.
A propelling electromagnet 152 is installed on the upper surface of the track 110 and the propelling electromagnet 152 includes a core 152a and a coil 152b surrounding the core 152a. The propelling electromagnet 152 is fixed to the orbit 110 via a fixing member 134. The propulsion electromagnet 152 is disposed to face the permanent magnet 124 installed on the truck 120 and a three-phase alternating current is applied to the propulsion electromagnet 152. Accordingly, the propulsion electromagnet 152 and the permanent magnet 124 form a linear motor.
As shown in FIGS. 3 and 4, the floating electromagnet 141 includes a core 141a and a coil 141b surrounding the core 141a. The core 141a includes protrusions 141ab and 141ac formed on both sides of the support base 141aa and the support base 141aa and a groove 141ad is formed between the protrusions 141ab and 141ac. The coil 141b is wound on the support 141aa and the two protrusions 141ab and 141ac are spaced apart from each other with the groove 141ad interposed therebetween.
The air gap fine adjustment electromagnet 142 includes a core 142a and a coil 142b surrounding the core 142a. The air gap fine adjustment electromagnet 142 includes two protruded protrusions 142aa and 142ab and a coil 142b is wound between the protrusions 142aa and 142ab. The gap fine adjustment electromagnet 142 is inserted into the groove 141ad and fixed to the floating electromagnet 141 via the support member 143. [ One end of the support member 143 is fixed to the outer surface of the gap fine adjustment electromagnet 142 and the other end of the support member 143 is fixed to the inside of the floating electromagnet 141.
The gap fine adjustment electromagnet 142 has a magnetic force smaller than that of the floating electromagnet 141. [ The magnetic force of the floating electromagnet 141 is 10 to 100 times the magnetic force of the gap fine adjustment electromagnet 142. The floatation electromagnet 141 is connected to a floatation current control unit 161 for controlling the amount of current applied to the float electromagnet 141 and an auxiliary current control unit 162 is connected to the gap fine adjustment electromagnet 142. Accordingly, the current applied to the floating electromagnet 141 and the gap fine adjustment electromagnet 142 can be controlled separately.
The first ferromagnetic plate 121 is disposed to face the floating electromagnet 141 and the second ferromagnetic plate 122 is disposed to face the gap fine adjustment electromagnet 142. Protrusions 121a and 121b facing the protrusions 141ab and 141ac of the floating electromagnet 141 are formed on the first ferromagnetic plate 121. [ The projections 121a and 121b are spaced apart with a groove 121c therebetween. On the other hand, the second ferromagnetic plate 122 is inserted in the groove 121c and has protrusions 122a and 122b facing the protrusions 142aa and 142ab of the gap fine adjustment electromagnet 142. The projections 122a and 122b are spaced apart from each other with the groove 122c therebetween.
Thus, the floating electromagnet 141 pulls the first ferromagnetic plate 121 to generate a floating force, and the gap fine adjustment electromagnet 142 pulls the second ferromagnetic plate 122 to control the floating force. The first and second ferromagnetic plates 121 and 122 having protrusions corresponding to the floating electromagnet 141 and the gap fine adjustment electromagnet 142 are installed to maximize the magnetic force .
When the current flowing through the floating electromagnet 141 is changed, the floating force of the floating electromagnet is changed. However, since the floating force varies greatly, it is difficult to precisely control the interval between the floating electromagnet 141 and the first ferromagnetic plate 121 there is a problem. However, since the gap fine adjustment electromagnet 142 forms a relatively small magnetic force as compared with the floating electromagnet 141, if the current flowing in the gap fine adjustment electromagnet 142 is controlled, the gap between the floating electromagnet 141 and the first ferromagnetic plate 121 Can be controlled with high precision.
