NBAA: Safran unveils electric motor
Safran is presenting the first electric motor from its ENGINeUS range, designed for future hybrid and electric aircraft, at this year's NBAA Convention.
Safran is presenting the first electric motor from its ENGINeUS range designed for future hybrid and electric aircraft, at NBAA’s Business Aviation Convention & Exhibition (NBAA-BACE) in Orlando, Florida.
According to Safran, the ENGINeUS 45 motor has a continuous power of 45kW. It has built-in, dedicated control electronics with an energy efficiency of over 94%. It offers a power-to-weight ratio of 2.5kW / kg at 2,500rpm. The ENGINeUS product line will eventually include a range of electric motors with a power output of up to 500kW.
The motor on display has been tested and validated on Safran's electrical integration benches to verify its performance. Safran has also tested four of these electric motors on the ground on a full distributed propulsion hybrid-electric system, which reflects the demands of hybrid and electric aircraft.
This motor technology optimizes the electrical architecture by consolidating several key conversion, control and battery interface functions. Its mechanical and structural characteristics are also perfectly suited to aircraft structures.
Hervé Blanc, Vice President & General Manager of the electrical systems and motors division at Safran Electrical & Power, says the new engines mark a major strategic shift towards the development of VTOL and STOL aircraft, thus opening up promising new markets for Safran.
Safran announced the first ground tests of a distributed hybrid electric propulsion system in July.
