Brush and Commutator

Brushes and commutators on any type of motor require routine inspection and service.

Sparking, along with chatter and chipping, are the tell-tale signs of brush / commutator malfunction. Sparking is easily detected by way of careful visual inspection. Solving a brush / commutator problem often hinges on an accurate estimation of the degree of sparking observed. Many factors, including the load, environment and application characteristics, may be involved in malfunctions of this nature.
