Generators & Starter-Generators

Aircraft generators and starter-generators are arranged for procurement searches by complete designation and electrical-machine type. The category includes signal generators, integrated drive generators and several GS and GSK starter-generator families. Similar prefixes do not confirm the same output, direction of rotation, cooling arrangement, drive interface or installation.

Generator and starter-generator families

Recorded examples include the GKCH61 signal generator, GP-21 integrated drive generator and GS-12TO, GS-18 and GS-24 starter-generator positions. Series and suffixes remain part of the product identity. Each model should be checked independently even when another unit shares the same family letters or a visually similar housing.

Electrical and mechanical interfaces must agree

Selection may involve nominal voltage, current or power, operating mode, rotational data, cooling, shaft or flange, mounting and the approved aircraft installation. Only values confirmed for the requested execution should be used. Compare the nameplate with the equipment specification, illustrated parts catalogue and relevant maintenance record.

• copy the exact designation and series;
• identify generator, starter-generator or signal-generator type;
• provide documented electrical ratings;
• include drive, rotation and mounting information;
• state quantity, condition and document requirements.

Request the matched electrical machine

Select the individual product card to request confirmation of identity, available condition, completeness, documentation, price and lead time. Service parts for rotating electrical contact assemblies can be found under Aircraft Carbon Brushes. Related starting controls are listed in Starting Units and Starter Panels.
