The new Siemens engine stands out for being very powerful and made specifically for aircraft, with only 50kg and 260kw of power and a maximum speed of 2500rpm, which allows it to be connected directly to a propeller without the need for a reduction box. Powerful enough to lift a 4-person aircraft smoothly. “This innovation will make it possible to build aircraft with a series hybrid-electric propulsion system with four or more seats“, said Frank Anton, head of eAircraft at Siemens Corporate Technology.
Among its innovations is the new alloy made for the stator in cobalt-iron, in addition to a special assembly of the magnets that contributes to directing the flux to only one side. Cooling is done by fluids and the structure that connects the engine to the propeller was reduced by almost 6 kg in its previous weight.
Siemens plans to begin testing by the end of 2015. Siemens' goal is to have 50 to 100-seat aircraft with electric or hybrid propulsion by 2035 just by developing this engine.
The old electric motor (DA36 E-Star 2) presented in 2013 was capable of 60KW with only 13kg, this motor equipped the DA36 an aircraft made in partnership with Siemens, EADS and Diamond Aircraft.
