For the application of high speed maglev system, a high temperature superconducting linear synchronous motor (HTSLSM) system is proposed. A 2D model is established by using finite element analysis（FEA） method. The flux linkage, magnetic field, thrust and normal force of HTSLSM are studied. The influence of the transverse dimension of the HTSLSM and the air gap between the primary and the secondary on the motor thrust and normal force is analyzed. The characteristics between HTSLSM with air-cored coils and linear synchronous motor (LSM) used on EMS high speed maglev train are also compared. The analysis results benefit the development of HTSLSM used on maglev transportation.
