With the continuous development of high temperature superconducting magnet technology, this paper puts forward a new type of electromagnetic analysis method about high temperature superconducting linear synchronous motor based on 2 generation （2G） high temperature superconducting coils. According to electromagnetic design principle of permanent magnet synchronous linear motor, high temperature superconducting magnet is used to replace permanent magnets, and the HTS synchronous linear motor is designed and studied; this paper established the mathematical model of high temperature superconductors in theory, put forward the calculation method of the motor thrust, and set up 2 D simulation model of the motor, and calculated electromagnetic field, electromagnetic force and starting speed of the motor in static and dynamic conditions via a professional finite element software and also analyzed the start-up characteristics respectively to different dynamic qualities and different working frequencies. Finally, the study on characteristics of varying-frequency startup of the motor verified the feasibility of varying-frequency startup with the maximum speed mode in HTS synchronous linear motor. Based on this design and simulation, we successfully developed the corresponding principle prototype in laboratory.
