SECTION 2 -BRUSH DESIGN, MANUFACTURE AND APPLICATION
Question 2:10 Why Do Some Brushes Have Grooves In The Side Or Internal Faces?
These are grooves which minimize the risk of carbon dust building up on the brush faces which, if not cleaned out, can result in the brush seizing in the holder.
The grooves tend to clear the dust assisted by air movement through the grooves. Dust grooves are most commonly applied to slip ring brushes where the copper dust is more prone to building up inside the holders.
DC motor brushes can also have grooves on the outside or inside faces.
Low voltage forklift motor and traction motor brushes often have dagonal grooves across the outer faces.
