Investigation of Power Losses in the 300kW Superconductive Generator

Abstract

Previous measurements of the current collector power losses in the 3OOkW superconductive generator have shown the losses to be much higher than predicted by theory. The purposes of these experiments was to isolate the source and magnitude of the power losses with more accurate experimental methods and data collection techniques. The losses could then be theoretically extrapolated to predict losses in a full scale machine for ship propulsion. The results showed that the excessive losses were fluid losses due to overfilling of the current collectors with liquid metal, and eddy current losses in the rotor bearings due to the rotation of the electrically conducting balls in the magnetic field.
