The SGT-3 Starter Generator is a combined electromechanical unit designed for engine starting and continuous onboard DC power generation in helicopter electrical systems. During engine start, the unit operates in starter mode using a 24 V power supply and high starting current, providing reliable acceleration of the engine to self-sustaining speed. After start-up, the SGT-3 automatically transitions into generator mode, delivering stable 28.5 V electrical power with a rated output of 3 kW.

The SGT-3 starter generator is applied on transport and utility helicopters of Soviet and Russian origin as part of the main electrical power supply and engine starting systems. It supports the operation of avionics, navigation equipment, lighting, and auxiliary onboard systems. Designed for continuous operation under variable rotational speeds up to 11,250 rpm, the unit demonstrates high durability under vibration and mechanical loads typical for rotorcraft эксплуатации. Proven engineering design and stable electrical performance make the SGT-3 Starter Generator a reliable solution for fleet operators and MRO organizations.
