Here’s a guide to the health and welfare of your brushes.  From Gulf Electroquip page here.  This is so awesome I printed a pdf of it, just in case they decide to move it…  download that here: BrushWearGuide

They credit Helwig Carbon, here, which has a very interesting collection of technical and white papers, here.  Want to read a great primer on brushes and commutators in general?  Check out “Brushholders and Performance of Carbon Brushes“.  Oh yeah, you can buy your brushes there too… it looks like you can even order them by size.  Shop Helwig Carbon.

As long as we’re thinking about brushes going bad, how about a nice high-speed video of commutator arcing with some awesomely dramatic music?  I thought you’d never ask.  Here you go:

All this cool brush stuff?  Give it up to Gasless, on the Facebook. Thanks guys!
