  • Carbon brushes in sealed silicone environment with controlled vapor pressure
    Patent number: 4659954
    Abstract: A sealed enclosure surrounding the brushes and metallic contact members of a dynamoelectric machine is maintained at a positive pressure with an inert gas. A predetermined vapor pressure of a silicone lubricant is maintained in the sealed enclosure. The silicone lubricant mixes with a carbon film on the surface of the metallic contact members to produce a highly lubricating, low-resistance layer which improves the wear resistance and predictability of wear of the carbon brushes.
