Starter Generator – DC 23080 Series II

Description

The 23080 Series II DC Starter Generators include part numbers: 23080-005, 23080-005-1, 23080-006, 23080-015, 23080-050, 23080-064. 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 starter generator utilizes a series starting field and should be started with the shunt field de-energized. For models 23080 Series II, the generator’s electrical system is rated at 28 VDC at operating speeds from 6,800 to 12,000rpm under a maximum 400A continuous load condition. The Output Rating is 12kW. 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.
