During his presentation, Lozowski discussed best practices for DC equipment on shovels, draglines and trucks. He also addressed how to improve generator and motor performance through careful maintenance and operation, the part that adequate brush film plays in current transfer and slip ring/commutator maintenance, and ways to reduce brush sparking and other brush wear issues.

In addition to selecting the most appropriate brush grade for a given application, ensuring the roundness of a commutator or slip ring is crucial to lengthening these parts’ service life. The new MSPro14 profiler from Morgan measures the roundness of commutators and slip rings, allowing users to identify problems before they impact brush performance.
