Superconducting electrical motors.

Author(s) : TIXADOR P.

Type of article: Article, IJR article

Summary

The historical development of superconducting machines is quickly reviewed. High critical temperature superconductors have stimulated studies on superconducting machines. Different motor options are presented (fully superconducting machine and permanent magnet superconducting motor). For each, the choice of the superconductor (low or high critical temperature) is discussed, according to their performance and technological problems, especially in terms of cryogenics. The different solutions are compared through a preliminary electromagnetic design for a 10 megawatt-100 rpm torque motor. The author carries out a research and development program on the permanent magnet superconducting motors. After a first 15 kilowatt-750 rpm successfully tested model a second 150 kilowatt-400 rpm demonstrator is under development.
