The study on high temperature superconducting (HTS) bulk magnets and their application has attracted much attention. This paper presents the performance analysis of a linear synchronous motor (LSM) with HTS bulk magnets for driving an HTS maglev vehicle model. Finite element magnetic field analysis is carried out for computing the magnetic field distribution and key parameters of the LSM, and an equivalent...
This paper applies the Radial Basis function (RBF) collocation method to compute the eddy current magnetic field coupled with conductor movement. Because of the linear characteristic of the RBF collocation matrix equation, the unknown magnetic vector potential could be easily decoupled and directly expressed in moving coordinate systems without model recast. This offers a great convenience to deal...
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.
