1.) Carbon Brush

Carbon Brush conducts current between rotating and stationary parts of generator or motor. A Carbon Brush is a metal or carbon conductor that maintains sliding contact between the stationary and the moving parts of an electric motor or generator.

A wide variety of carbon brushes are used in the following applications:

• Automobile Electrical Equipment
  
  • Electric power steering systems, fuel injection pumps, ABS, windshield wipers, power windows, throttle control, power door locks and power door mirrors,etc.
• Electricpower Tools
  • Circular saws, electric drills, grinders, impact drivers and electric drivers,etc.
• Vacuum Cleaners
  • Household-use vacuum cleaners.
• Micro Motors
  • Hair dryers, electric tooth brushes, cameras, personal computers, printers and automatic vending machines.
• Slip-rings
  • Ferris wheels, aerogenerators, and auto reels, etc.

Carbon Brushes are made using a process known as "powder metallurgical technology." Producing metal products and materials using powder metallurgical technology involves mixing and blending several types of metal powder at a proper ratio, placing it in a mold, compacting and pressing it at high pressures, and then putting it in an oven for sintering at a temperature below the metal-fusion point. The term "powder metallurgical technology" is also often used to describe processes involving ingredients other than metal powder, such as carbon and oxide powder.
