Book Description
The results of previous investigations of electrical brush wear and contact drop are presented and the theories of the sliding contact are checked against these early investigations. There are practically no quantitative data concerning electrical brush wear in the literature, and no theories of the mechanism of electrical brush wear were found. Apparatus and a method of procedure were developed for obtaining reasonably consistent electrical brush wear measurements. All measurements were made upon sliprings sine it was desired to eliminate as many variables as possible. Humidity and temperature conditions were held constant at all times except when varied purposely to determine their effects upon brush wear. Direct current was used for all except one brief series of tests. The effects of humidity, brush pressure, ring speed, brush circuit potential and current density upon electrical brush wear were investigated. Tentative conclusions are drawn concerning the effect of each of the above factors upon electrical brush wear and contact drop. A new theory of the sliding contact based on the negative temperature coefficient of resistancy of copper oxide is proposed. A bibliography is included for the convenience of those who wish to consult the original articles from which citations have been made.
