Title:
MAGNETIC LEVITATION SYSTEM AND LEVITATION TRAIN
Document Type and Number:
WIPO Patent Application WO/2023/077573
Kind Code:
A1
Abstract:
A magnetic levitation system and a levitation train. The magnetic levitation system is applied to the levitation train, and comprises a levitation frame, a levitation permanent magnet, a levitation drive device and a guide permanent magnet, wherein the levitation frame comprises an upper levitation frame (3), a lower levitation frame (6) and a side levitation frame (4); the levitation permanent magnet comprises a first levitation permanent magnet (12) located on an upper surface of a track (7), and a second levitation permanent magnet (13) located on a lower surface of the upper levitation frame (3) and arranged opposite the first levitation permanent magnet (12) in a homopolar manner; the levitation drive device comprises a track linear electric motor (9) located on a lower surface of the track (7), and a levitation electromagnet (8) arranged on an upper surface of the lower levitation frame (6), and the levitation electromagnet (8) and the track linear electric motor (9) act upon each other by means of a traveling wave magnetic field to drive a train to move; and the guide permanent magnet comprises a first guide permanent magnet (10) located on surfaces of two sides of the track (7), and a second guide permanent magnet (11) which is located on the side levitation frame (4) and arranged opposite the first guide permanent magnet (10) in a homopolar manner. Static levitation of the train can be achieved by using a magnetic repulsion type levitation technique, and the aims of lightweight and low energy consumption of the train are thus achieved.
