Suspension electromagnet for medium-and-low-speed magnetic levitation train

Abstract

The invention discloses a suspension electromagnet for a medium-and-low-speed magnetic levitation train. The suspension electromagnet comprises an inner pole plate and an outer pole plate in opposite interval arrangement, wherein one or more than one iron core is connected in a gap formed between the inner pole plate and the outer pole plate, a coil is wound on the iron core, and outer side bulge parts are respectively arranged at the outer surface of the inner pole plate and the outer surface of the outer pole plate. The suspension electromagnet for the medium-and-low-speed magnetic levitation train provided by the invention has the advantages that the outer surface of the inner pole plate and the outer surface of the outer pole plate are made to be outwards bulged, according to electromagnetic simulation and practical operation experience, the reasonable cross section shapes of the inner pole plate and the outer pole plate are obtained, the mechanical structure and heat radiation factors are considered in a combined way for optimizing the three-dimensional structure, the magnetic saturation generated in partial regions can be effectively reduced, the levitation force is improved, and the structure intensity, the reliability and the heat radiation efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of suspension electromagnets, in particular to a suspension electromagnet for a medium-low speed maglev train. Background technique [0002] A maglev train is a train that is suspended in the air by magnetic force (that is, magnetic attraction and repulsion). Since the train is suspended in the air and has no mechanical contact with the track, the maglev train only suffers from air resistance during normal operation. [0003] Such as Figure 10 As shown, at present, the levitation electromagnet that medium-low speed maglev train adopts is mainly made up of 4 iron cores 14, inner pole plate 11, outer pole plate 12, coil 13 is wound on each iron core 14, inner pole plate 11 and outer pole plate 12 are formed. The pole plates 12 are all sheet-like structures, and the two ends of the four iron cores 14 are respectively fixed to the inner pole plate 11 and the outer pole plate 12 by bolts. According to the sign...
