High temperature superconducting linear induction motor （HTS LIM ） is significant for the development of urban rail transit. The HTS LIM was designed, using design theory of conventional copper windings linear induction motor as a reference. Combined with the properties of high temperature superconducting tapes, the structure of the superconducting coils was designed＇ and the coils were arranged adopting the single layer concentrated structure in the primary core. The Dewar was manufactured by adopting non magnetic material. Finally, various parts were assembled into HTS LIM test prototype. The model of HTS LIM was built and the simulation was executed by finite element analysis software ANSOFT. The copper windings trial prototype was manufactured and the linear motor traction test platform was set up to test the performance of the motor prototype testing. The test results and simulation results were analyzed to verify the rationality and feasibility of the design.
