Pipistrel offers type certified electric motor

Pipistrel Aircraft is making its electric propulsion system, the E-811, available to other aircraft designers and manufacturers worldwide.

The Pipistrel E-811 is the first electric engine certified for use in General Aviation, certified by EASA on 10 June 2020.

The E-811 engine combines a liquid-cooled electric motor and a liquid-cooled power controller. It offers 57.6kW (77hp) of peak power, and 49.2kW (66hp) of maximum continuous power.

Pipistrel says the E-811 is the ideal powerplant for powered sailplanes, UL, LSA and VLA aircraft, where a type certified engine is required. It may also be installed on Part-23 Level 1 aircraft and other distributed propulsion applications by applying special conditions.

The E-811 propulsion motor is an axial flux synchronous permanent magnet electric motor. Lighter and more compact, these motors are also more powerful than radial flux motors, making them ideal for their application in aviation, said Pipistrel.

The engine is entirely liquid-cooled through a single cooling circuit with a mixture of 50% water and 50% glycol. The cooling system is part of the installation and can be provided by Pipistrel.
