Three Maintenance Tips for Carbon Brush Holders


Helwig Carbon Team

A carbon brush holder is a critical components of an electric DC Motor or Generator, so it is very important that it is properly maintained. Whether you have spent a lot of time learning about how these machines work or not, knowing how to do regular maintenance on them will save a lot of money in the long run. Also remember that the design, quality, and durability of the carbon brush holder has a direct effect on how long the carbon brush itself will last. Here are three maintenance tips to keep in mind when working with a carbon brush holder on most equipment that has them.

  • Check the springs frequently. One of the parts of the carbon brush holder that will wear out periodically is the spring that brings the carbon brush in contact with contact surface. Weak or broken springs is a common problem when you see the brush life deteriorating. It is also important that all the springs on a unit have the same spring force.
  • Closely examine the carbon brush holder every time you change the brushes. This one may seem like a no brainer, but you would be surprised how many people simply change the brushes without looking at the carbon brush holder to see if it is damaged or if any deposits have formed on the inside that would inhibit proper movement of the carbon brush in the holder.
  • Examine each carbon brush holder for corrosion. Check the holders frequently to make sure that corrosion hasn’t started
  • Electrical equipment is a very expensive part of running a business, so the less downtime  for maintenance, the better off you are. When you keep an eye on how the parts of your machine are wearing, you can cut back on unnecessary down time.
