Starter Generator – DC 23078 Series



The 23078 Series DC Starter Generators manufactured or cataloged by Safran Power (TRW Lucas Goodrich) 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. Dependent upon the model of DC starter-generator, the starter generator operates as a shunt or series motor to accomplish engine starting. The Output Rating, continuous load within speed range, Rated Voltage vary please review (CMM). All models have a Self-limiting current load: 1,700 Amps, maximum @ 28 VDC. 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.
