Abstract : The unsatisfactory performance of collector and commutator brushes in motor generators aboard nuclear submarines is introduced with the hypothesis that these difficulties are the result of atmospheric contamination. Following a survey of previously encountered contamination problems the experimental apparatus and procedures used to test this theory are described. Results of operation in eight simulated submarine environments are provided. (Author)
