Brush/Slip Ring Selection for High Power Satellite Loads.

Abstract

This report presents the results of vacuum tests of dry lubricant brush materials for usage in slip ring assemblies of satellites with large electrical loads. Primary concerns of the test were brush voltage drop, wear rate, and operating temperature at high current densities with a slow slip ring angular velocity. (Author)
