The minimum speed for regulation is 4,400 rpm, the maximum is 10,000, and the overspeed is 11,000 rpm. The drive spine is 16-tooth, and the rotation viewed from the drive end is counterclockwise. Generally, the 30E20 Series Starter Generators are used on turbine helicopter, turboprop, and light jet aircraft serving the commercial and military sectors .
