Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the beam structure electromagnet of the present invention's constant conduction attraction type maglev train includes pole plates 12, more than one iron core 11 arranged in sequence and a wire package 13 wound on the iron core 11, and the pole plates 12 are a whole The blocks are installed on the sides of all iron cores 11, and the pole plates 12 are connected with the iron cores 11 by threaded connectors. The wire package 13 generates an electromagnetic field after being energized, and the iron core 11 and the track 4 form a magnetic field path, in which the magnetic field forms a loop to generate an electromagnetic force to make the vehicle float. The iron core 11 is made of magnetically conductive steel. In order to make the electromagnet easy to make, the ...

Abstract

The invention discloses an electromagnet in a girder structure for a normally-conductive attraction type maglev train. The electromagnet comprises a polar plate, more than one iron core arranged sequentially, and coils which are wound on the iron core, wherein the polar plate is integrated and arranged on side faces of all iron cores. The electromagnet has the advantages of simple and compact structure, low cost, convenience for installation, stable and reliable operation, and the like.

Description

technical field [0001] The invention mainly relates to the field of maglev trains, in particular to an electromagnet which is mainly suitable for a maglev train of a normally conducting and attracting type. Background technique [0002] The magnetic levitation vehicle of the constant conduction attraction type floats the whole vehicle by electromagnetic attraction, so that the vehicle does not touch the track, and the electromagnetic force is provided by the levitation electromagnet. To generate sufficient buoyancy, see Figure 8 and Figure 9 As shown, the electromagnets 1 are generally distributed on both sides of the vehicle body 3 along the entire length of the vehicle and installed on the bogie 2 . The structure of the existing electromagnet 1 is only considered from the perspective of electromagnetic levitation, that is, the structure of the electromagnet 1 only considers the design requirements of electromagnetic force. The structure only considers the magnetic flux...
