For the first time Siemens presented its’ world-record electric motor for aircraft at the international Paris Air Show. The motor in the aerobatic plane Extra 330LE was demonstrated at the daily air show where the electric powered Extra took a glider up to the air.
In addition to the 260 Kilowatts world-record electric motor, Siemens also presented two further propulsion systems of different power classes.In a big leap for the electrification of aviation, an Extra Aircraft aerobatic plane performed its maiden flight with an electric powertrain.
The crucial component was a world record motor from Siemens. Weighing a mere 50 kilograms, the motor has an output of 260 kilowatts, resulting in an unparalleled power-to-weight ratio.
Thanks to its record-setting power-to-weight ratio, larger aircraft with takeoff weights of up to two tons will now be able to use electric drives for the first time.To implement the world-record motor, Siemens’ experts scrutinized all the components of previous motors and optimized them up to their technical limits.read more (siemens).
Tle strength that are used in industrial applications deliver less than one kW per kg. The performance of the drive systems used in electric vehicles is about two kW per kg.This innovation will make it possible to build series hybrid-electric aircraft with four or more seats,” said Frank Anton, Head of eAircraft at Siemens Corporate Technology.
