The alveolar structure parameters have significant effects on the performance of high temperature superconducting （HTS） linear induction motor. In order to study the effects of these structure parameters on the motor performance, using the transient 2D finite element analysis in this paper, the effects of slot width, slot height, and tooth width on electromagnetic proper- ties of motor, the maximum vertical field of high superconducting windings and the maximum operating current of the motor were discussed respectively. Relationship among the maximum operating current of HTS motor, slot width, slot height was gotten. In addition , we obtained the critical slot width and critical slot height of structure optimized. The research and analysis in this paper show that the alveolar structure parameters optimized can be in favor of improving the current flow capacity and increasing electromagnetic force of the HTS linear induction motor.
