Barlok(tm) molded commutators expand the performance characteristics of mica molded commutator to the tough performance and service life requirements usually associated with steel and mica commutators.

• Custom designed fiberglass rings ensure maximum bar stability
• Unique design achieves maximum strength at high motor speeds
• Fiberglass rings and commutator bar design are custom engineered using a proprietary computer stress analysis CAD system
• This ensures design will match thermal, centrifugal and electrical requirements dictated by operating conditions
• This also ensures maximum commutator burst speeds from 20 to 50 percent or more over maximum operating conditions
• Utilize high strength, thermoset phenolic compounds, specially designed for Barlok style commutators
• Each compound grade is selected to meet demanding mechanical and thermal requirements for high performance molded commutator applications
• Available for molded commutators up to 9" in diameter, with flush or subflush mica
