Journal ArticleDOI
A two-pole Halbach permanent magnet guideway for high temperature superconducting Maglev vehicle
Hua Jing,Jukun Wang,S. Y. Wang,Lianzhou Wang,Liu Liyuan,Jun Zheng,Zigang Deng,Guangtong Ma,Y. Zhang,Jie Li +9 more
TL;DR: In this paper, a two-pole Halbach array's permanent magnet guideway (PMG) is proposed, which is called as Halbach PMG, to improve the performance of the high temperature superconducting (HTS) magnetic levitation (Maglev) vehicle.
Journal ArticleDOI
High-efficiency and low-cost permanent magnet guideway consideration for high-Tc superconducting Maglev vehicle practical application
Zigang Deng,Jukun Wang,Jun Zheng,Hailian Jing,Y Y Lu,Guangtong Ma,Lian Liu,Wei Liu,Y. Zhang,S. Y. Wang +9 more
TL;DR: In this article, the double-pole Halbach permanent magnet guideway (PMG) concept was introduced to improve the cost performance of the present high-Tc superconducting (HTS) Maglev vehicle system.
Journal ArticleDOI
Superconducting magnetic bearings simulation using an H-formulation finite element model
TL;DR: In this article, a flexible, fast and trustworthy H-formulation finite element model for modeling superconducting magnetic bearings (SMBs) is presented, which can be used for speeding up the development of numerous applications including maglev vehicles, magnetic launchers, flywheel energy storage systems, motor bearings and cosmic microwave background polarimeters.
Journal ArticleDOI
Experiment and simulation of superconducting magnetic levitation with REBCO coated conductor stacks
TL;DR: In this article, three superconducting stacks made of 120 REBCO coated conductor tapes were each fabricated and assembled to obtain several REBO modules, and their levitation responses over two different permanent magnet (PM) guideways were investigated by experiment and finite element simulation.
Journal ArticleDOI
Method to reduce levitation force decay of the bulk HTSC above the NdFeB guideway due to lateral movement
TL;DR: In this article, a pre-load method is presented to reduce the LF decay, and the experimental results indicate that this method is very applicable in supressing this decay in spite of the applied field and material property of the bulk high-Tc superconductors, and this effect can be ascribed to the reduction of the hysteresis loss in the bulk HTSC.
