“…Since stable levitation force can be generated between NdFeB permanents magnets (PMs) and HTS bulks bathed in liquid nitrogen [6,7], HTS magnetic levitation system containing PMs and HTS bulks can be used in a HTS LSM to replace the conventional slide rail [8]. The main advantage of HTS magnetic levitation system is the strong levitating force with passive and self-stabilizing feature, leading to the removal of the sophisticated control system for regulating the air-gap between PM-guideway and levitated moving secondary, which is necessary for other types of levitation transportation systems.…”

Abstract-High temperature superconducting (HTS) linear synchronous motor (LSM) integrated with HTS magnetic levitation system, can realize self-levitation and self-guidance without any sliding friction, which will have important applications in many fields such as electromagnetic aircraft launch system, maglev transportation. This paper presents the design and electromagnetic analysis of a HTS LSM, which is levitated by a magnetic levitation system consisting of HTS bulkspermanent magnet (PM) guideways. Numerical analysis and magnetic field finite element analysis (FEA) methods are applied to analyze the thrust, levitation and guidance force characteristics, and the electromagnetic performance of HTS LSM under no-load and load situations are studied with the analysis results are given. Finally, the primary motor running testing results are provided.

“…Because stable levitation force can be generated between NdFeB permanents magnets (PMs) and high temperature superconducting (HTS) bulks [3], HTS levitation system contained PMs and HTS bulks can be combined into SLIM. The main advantage of HTS levitation system is the strong levitating force with passive and selfstabilizing feature [4], leading to the removal of the sophisticated control system for regulating the air-gap between guideway and levitated moving secondary, which is necessary for other types of levitation transportation systems.…”
