Development of High Temperature Superconducting Machines

Abstract

Since 1990s, high temperature superconducting (HTS) machine techniques have been gradually developed. The developed HTS machines mainly include DC machines, synchronous machines, induction machines, linear machines, reluctance machines, hysteresis machines, and permanent machines. From the beginning of this century, the HTS machines have made rapid developments and significant achievements. HTS motors and generators are summarized in this paper with regard to their developments, advantages and prospect applications.
