SECTION 2 -BRUSH DESIGN, MANUFACTURE AND APPLICATION
Question 2:5 Why Are Brush Split?
Split wafer brushes increase the number of contact points from the brush face to the collector surface. Each solid block has approximately 10 actual contact points regardless of the contact area.
By splitting the same area into two wafers the number of the contact points is substantially increases.
The split also introduces additional cross resistance into the commutation process which is an added benefit.
By far the most common are parallel wafers however for some machines with particularly difficult commutation the split can be angled. Departure of the leading wafer and the entry of the second into the contact zone is angled giving a graduated change in contact resistance which assists the commutation process.
Question 2:6 Are Split Brushes Always The Same Grade in Both Pieces?
