What is a commutator? - Motion Control Tips

Jan 07, 2016  The commutator itself is a split ring, typically made of copper, with each segment of the ring attached to each end of the armature coil. If the armature has multiple coils, the commutator will similarly have multiple segments—one for each end of each coil. Spring-loaded brushes sit on each side of the commutator and make contact with the ...

How do I stop the commutator from sparking ...

What causes commutator arcing? If the sparks go all the way around the copper strips, also called the commutator, the armature has shorted. That means the insulation between the wires and the iron has broken down in the inside of the armature. Some times it can be as simple as a short between the bars, the copper strips, of the commutator.
