The Safran ENGINeUS is a family of electric motors for aircraft propulsion developed by Safran. In early 2025, the engine had a maximum output of 125 kilowatts.
At the October 2018 NBAA convention, Safran presented its ENGINeUS electric motor range up to designed for electric aircraft, starting with a one with integrated control electronics, with an energy efficiency of over 94% and a power-to-weight ratio of 2.5 kW / kg at 2,500 rpm and of torque, for a weight with the controller, without.
The engine originally had output up to .
In 2020, Bye Aerospace began using the EngineUS 100 product on its eFlyer 2 and eFlyer 4 electric aircraft.
In Feb. 2025, manufacturers such as Electra, Diamond, VoltAero, CAE, and Bye Aerospace were using the engines.
In February 2025, the ENGINeUS series became the first engine certified as airworthy under the EASA special condition SC E-19, for electric and hybrid propulsion engines. The approval allowed Safran to begin installing them on small aircraft, beginning with the eDA40 by Diamond Aircraft. The approval process had taken four years. With the announcement, Safran said it would begin increasing production, and Safran was building four production lines in the UK and France with the intent of producing around 1,000 of the motors per year.
Ascendance in March 2025 selected ENGINeUS for its prototype flying ATEA, a hybrid-electrical helicopter.
In early 2025, the engine had a maximum output of 125 kilowatts.
The ENGINeUS 45 air-cooled direct-drive Smart Motor (integrating motor and power electronic converter) produces maximum and continuously, has a power-to-weight ratio of 2.5 kW/kg at 2,500 rpm and an efficiency over 94%.
