*Abstract

Effectively Reduces Brush Wear Problems in Superconducting Electrical Motors

This military grade, electrically conductive solid lubricant significantly reduces wear rates and friction. Solid lubricants are used to solve a wide variety of lubrication problems in mechanical applications such as: aircraft, watercraft, antennae, radar systems and electric motors. Typically available solid lubricants have been ineffective in reducing wear rates and friction in high demand applications such as superconducting electrical motors. University of Florida engineers have developed an electrically conductive solid lubricant which can meet or exceed standards for reducing wear rates and friction in current applications as well as future applications utilizing superconductivity.

Applications

Electrically conductive solid lubricant with a wide range of commercial and military applications including but not limited to:

Aircraft
Watercraft (ships, submarines)
Antennae systems
Directional radar systems
Electrical motors

Advantages

Reduces friction and wear significantly better than existing lubricants, providing major competitive advantage
Costs less to produce than oil based lubrication systems, providing opportunity to enhance profit margins
Solid lubricants are used in a wide variety of industries, offering broad market applications
Solid lubricants demonstrate effective performance in superconductivity environments, providing market potential (e.g. aerospace, energy exploration and production, commercial research)

Technology

One of the primary goals of lubricants is to reduce wear rates and friction. In electrical applications, such as using sliding electrical contacts to connect two electrically conductive members, the lubricant must also be highly electrically conductive. Using electrically conductive solid lubricants, transfer films, soft metals and methods for application, UF researchers have developed a lubricant system that can improve existing mechanical applications and accelerate the development of future (superconductive) applications.
