This project contributes to e-mobility by developing, producing and verifying electromechanical actuators of two different load ratings, intended to be used for primary flight control surfaces of CS-23 and Urban Air Mobility aircraft. The project was solved in cooperation with Honeywell International and ATAS Electromotors Nachod. The two prime results are the EMA1 and EMA2 fully assembled electro-mechanical actuators, consisting of the mechanical part of the actuator and the PMSM motor with integrated resolver with nominal power of 3000 N and 1000 N, respectively. The actuators are intended to control the control surfaces, i.e. the ailerons, flaps, elevators and rudders of an aircraft. Additionally, a two-pole resolver used to determine the instantaneous position of the rotor relative to the stator of synchronous machine was developed to be applied primary for flight surfaces control in aircraft. Its main advantages of this resolver are its low weight, the ability to operate in a wide range of ambient temperatures and its long service life.

Developed electromechanical actuators not only enhance the efficiency of primary flight control systems but also contribute significantly to the broader trend of aircraft electrification. By replacing traditional electro-hydrostatic actuators, they enable a 7% weight reduction per unit, which, when scaled across an aircraft’s control surfaces, can lead to a total weight savings of up to 50 kg per aircraft. This reduction minimizes the reliance on hydraulic components and fluids, ultimately lowering fuel consumption and emissions while improving overall aircraft performance and sustainability.
