Abstract

The embodiment of the invention discloses a suspension electromagnet based on a medium and low speed maglev train, which comprises a hybrid magnet corresponding to an F-shaped orbit and an excitationcoil corresponding to the hybrid magnet, the hybrid magnet comprises an electromagnet and two permanent magnets, the electromagnet comprises a bottom iron, an inner plate and an outer plate, the innerplate and the outer plate are located on inside and outside of the bottom iron respectively, and the two permanent magnets are arranged correspondingly between the inner plate and the bottom iron andthe outer plate and the bottom iron respectively, and the two sides of the bottom iron are higher than that of the middle height. By adopting the hybrid magnet, the effective area and the length of the permanent magnet are no longer limited by the installation and size of the electromagnet, the deivce has the advantages of that the hybrid magnet not only improves an electromagnetic force, but also is favorable for steering stability, meanwhile, effectively improves a magnetic saturation and a suspension performance, and achieves a performance optimization of medium and low speed maglev trainsystem.

Description

technical field [0001] The invention relates to the technical field of maglev trains, in particular to a suspension electromagnet based on a medium-low speed maglev train. Background technique [0002] With the rapid development of urban rail transit, the research on maglev trains has attracted more and more attention. Maglev trains are divided into electromagnetic levitation type and electric levitation type. The medium and low-speed magnetic levitation is electromagnetic levitation. As the moving speed increases, the eddy current effect of the rail increases, resulting in a corresponding decrease in the levitation force and lateral guiding force of the electromagnet, and the amplitude gradually decreases. The existing suspension electromagnet has low electromagnetic force and serious magnetic saturation phenomenon, which is not conducive to guiding stability. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present inventi...
