RE: (ET) Brushes for sweeper
National Carbon Products makes brushes.....(800)395-7776
Located in Greenville SC.
If you provide the motor model number, I can see if a drawing exists as I
work for GE Motors. That would make it easier. As a last resort, you can
measure the width and thickness and guesstimate a length and ask them for
Brushwear is related to surface speed, sparking, spring tension, and
commutator roughness. Cleaning the commutator with non-metallic sandpaper
will help and make sure no mica fins between the segments are sticking up
due to copper wear.
Silicone sealant also makes brushes wear extremely fast - do not seal the
motors with it.....great for the bathroom but not for dc motors.

Subject: (ET) Brushes for sweeper
Does anyone know where I can find spare brushes for the Elec-trak
sweeper? At the same time is it ok to run the motor on that at a
somewhat slower speed? It really picks up well but I think it's going to
beat the brushes to death.
