Abstract : The objective of the program is to contribute toward new and improved rotating machines for Naval applications, with emphasis on superconducting machinery. An important factor in the design of superconducting machinery is the A.C. hysteresis and eddy current loss which occurs in the multifilament conductors generally used for A.C. operation. Reduction of this loss, to reduce the required refrigeration capacity, is necessary for wide-range use of superconducting machines. Theory has been developed and substantial progress has been made toward understanding the A.C. loss in multifilament conductors. The theory may be used for the design of optimum conductors. In the area of actual machine research, a low speed, high torque heteropolar D.C. superconducting motor has been studied with encouraging results. In addition the maximum power rating of various types of D.C. machines has been estimated. (Author)
