What are starter generators? A detailed article by NAASCO's Jim Leslie
Since 1984 NAASCO's technical and engineering improvements have revolutionized the Starter Generator industry. Regional Airlines, Helicopter and Corporate Operators around the world benefit from NAASCO's innovations that have led to 1000 hour time between overhauls on a wide variety of starter generators.
Do Your Brushes Look This Good?
Actual photo of armature commutator and NAASCO's ETR brushes as removed from unit with 1067.3 hours of service. Starter generator had been overhauled with our advanced ETR-20 improvements. Commutator wear measured at .003" (compared to typical wear of .040" to .055" with abrasive OEM carbon brushes).
Note that wear indicator line from our ETR brushes shows 55% brush wear from original set of brushes at overhaul.
