No-Load Testing of the Shaped Field Super-Conductive Motor.
Abstract
A laboratory-model superconductive d.c. motor, designed and constructed at the David W. Taylor Naval Ship Research and Development Center for peak power output in the 400 to 1000 hp range, has been undergoing no-load testing since January 1973. Results, reported herein, substantially validate the loss estimates (6.5 kW total power loss at 1800 rpm, 120 amp field current, open circuit) predicted in a prior analysis, and indicate that no major problems should be encountered in future planned load tests, with the possible exception of the collector electromagnetic stability, which cannot be evaluated satisfactorily at no-load conditions. Background information on machine development and discussions of the liquid metal and cryogenic helium handling procedures are also included. (Author)
