J-8 superconducting D.C. machines - Concerning mainly civil marine propulsion but with mention of industrial applications

Abstract

This paper discusses the current status of superconducting, d.c. motors and generators with particular regard to civil marine propulsion. It commences with a brief account of the factors which help to ensure reliability and proceeds to enumerate the advantages which are expected from superconducting d.c. marine propulsion systems. Following a mention of a practical demonstration of the latter, now under test at IRD, the paper concludes with assessment of the general market for the machines. Also, included in the paper is some mention of industrial applications for these new machines.
