With the improvement of high temperature superconducting （HTS） material technology, HTS linear motors （LM） which are built using HTS bulks and HTS tapes have been realized. In this paper, different types of the developed HTS LMs are summarized with their structure models. The electromagnetic characteristics of these HTS LMs are studied with the results obtained by using magnetic field finite element method. Superiorities of the HTS LM technology are also verified with its applications in transportation field such as maglev and electromagnetic aircraft launcher.
