The present invention provides an electric aircraft engine. It also provides an aircraft, comprising such an electric aircraft engine. According to both a first aspect and a second aspect of the present invention, the electric aircraft engine comprises an electric motor with a rotor configured to be driven in rotation about a central axis, a fan having a central yoke mechanically coupled to the rotor for driving the fan and a plurality of fan blades projecting radially outwardly from the yoke, and an anti-icing and/or de-icing system to remove and/or prevent built-up of ice on the fan, said anti-icing and/or de-icing system comprising an electrical power source and a wireless energy transfer system for wirelessly transferring energy for anti-icing and/or de-icing from the electrical power source to the fan. In the first aspect of the present invention, the electric motor comprises an electromagnetically excited resolver for determining an angular position of the rotor of the electric motor, and an anti-icing and/or de-icing control unit is configured to induce losses by adding a high-power, highfrequency component of current and flux to the normal excitation signals of the resolver, thereby heating up the resolver. In the second aspect of the present invention, the wireless energy transfer system consists of two coils, a transmitter coil electrically coupled to the electrical power source and a receiver coil thermally connected to the fan, the energy being transmitted wirelessly by induction via an air gap from the transmitter coil to the receiver coil.
