Copper Graphite Brushes

    Copper-graphite brushes are made from electric copper powders and graphite using a mixture firing to obtain a high-quality composite material, the product is shaped by pressing.

    Copper-graphite brushes have a low electrical resistance, combined with the ability to work at high current densities. Thus, the brushes ensure the reliability of the chains of traction motors and electric machines, which are units of the rolling stock of railway transport, diesel locomotives, electric locomotives, motors of units of the mining and processing and metallurgical industries, lifting mechanisms, urban transport.

    Depending on the brand, the copper-graphite brush has different uses, here are several options:

  • brush MG, brush M50 - asynchronous electric motors with a phase rotor, starters - the voltage of which is not more than 6V, DC electric machines - the voltage of which is not more than 12V, welding generators;
  • brush M1, brush M1A - single-armature converters, synchronous generators, asynchronous electric motors with a phase rotor, charging generators whose voltage is from 20V to 60V, alternators for automotive equipment;
  • brush M6 - generators and motors with low power, the voltage of which reaches 25-30V;
