DC Repairs

Small problems left unattended can result in unexpected failures and production breakdowns.

DC motors need frequent maintenance due to various speeds, types of loads and contaminants, in addition to normal brush and commutator wear. Our careful examination and special test procedures using surge, high frequency, hipot dynamometer, PDMA and megger testing are fundamental at Matlock. Precision tolerances and proper brush grades are required to maintain good commutator and brush life.


Our DC department follows meticulous repair specifications to produce the highest quality and most reliable rebuilds in the industry. All coils are wound on computerized machines for uniformity utilizing Class H wire, phase insulation and all insulating components. All units are dynamometer load tested prior to shipment; this insures that the units can operate properly in the harsh conditions of a plant setting.
