Commutator Discs Made of Graphite for Electric Motors

Given the increase use of fuel mixes featuring a high share of ethanol, commutator discs made of specialty graphites are playing an increasingly important role in electric motors for fuel pumps. These materials are inherently much more corrosion resistant than standard copper discs, making them better suited as components in fuel pumps. This is especially true when striving for compliance with safety and endurance specifications.

Notable features:

  • Strong thermal resistance
  • Good self-lubricating properties
  • Corrosion resistance
  • High mechanical strength
