Starter Generator – DC 23080 Series VI

Description

The 23080 Series VI DC Starter Generators include part numbers: 23080-019 and 23080-054. They are manufactured or cataloged by Safran Power (TRW Lucas Goodrich) and operate as a motor to provide torque for engine starting and as a generator to provide DC electrical power after 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 Output Rating is 12kW and the external starting power supply is a self-limiting current load of 2,000 Amps max at 28 VDC, .005 Ohms aircraft circuit resistance. The rated speed range: 27 VDC at 400 amps over 6,800 to 12,000 rpm (with 0.5 ohms in external field circuit). Generally, these Starter Generators are used on turboprop and light jet 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.
