Abstract: Superconducting linear induction motor is a new type of linear motor. In this paper, the influence of electromagnetic parameters of superconducting linear motor on the electromagnetic properties, such as  electromagnetic thrust, vertical force and maximum vertical magnetic field of the motor was researched. The simulation of the motor was executed by using finite element analysis software Ansoft. Then the influence of electromagnetic parameters on electromagnetic properties was analyzed. The conclusion that electromagnetic thrust force, vertical force and maximum vertical field are proportional to the current size and frequency can be obtained through research and analysis. This allows a better understanding of characteristics of the superconducting linear induction motor , and it is important for the further study of the motor.
