Starter Generator – DC 23069 Series

Description

The 23069 Series DC Starter Generators manufactured or cataloged by Safran Power (TRW Lucas Goodrich) is designed to provide torque for engine starting and to generate 30 VDC electrical power once engine starting is accomplished. When used as an engine starter, the starter generator can be energized either by batteries or by ground-power units. The starter-generator utilizes a series starting field and should be started with the shunt field de-energized. The Output Rating is 9 Kilowatts, and the Rated Voltage is 30VDC. The Speed Range is 6650* rpm to 12,000 rpm (*26 V with 0.20 Ω in external field), and the starter maximum Voltage is 28 VDC. Generally, these Starter Generators are used on turboprop aircraft serving the commercial and military sectors and are self-excited machines incorporating four main poles and four interpoles. During on-ground operation, a fan attached to the anti-drive end of the drive shaft supplies forced-air cooling. In flight, the starter-generator, in addition to the fan, is blast-cooled through the air inlet and the aircraft’s air duct system.
