Abstract:

Current collectors for high power capacity acyclic machinery with superconductive fields are discussed in this report. It is found that liquid metal collectors offer superior performance characteristics for machines of this type. Consideration of solid collectors shows that the requirements of this application are beyond the present state of solid brush technology. The influence of ambient magnetic fields on the behavior of liquid metal collectors is analyzed. It is found that the collector performance is such that attractive, high power capacity machines can be specified. Design equations for machines with superconductive fields and liquid metal collectors are developed. A model generator developed to experimentally confirm the study results is described. The results of test runs on this machine are reviewed. The results served to verify the theoretical predictions related to these machines. Author
