Classification: CPC B  Y | IPC B

Claim 0:
1. A swashplate-less two-degree of freedom rotor of an Aerial Drone Aircraft (ADA), comprising:
a motor driving a first shaft around a primary axis (A)
two blades joined together by a second shaft oriented along a secondary axis (B) perpendicular to said primary axis (A), and fixed to said first shaft by means of a first mechanical part and a second mechanical part, said first mechanical part being adapted to tilt relatively to said second mechanical part around said secondary axis (B), while being centered on said primary axis (A), so as to transmit tilting motion to said blades,
a magnet that is diametrically-magnetized and attached to said first mechanical part, so that said first mechanical part and said magnet can rotate about said primary axis (A) and tilt about said secondary shaft,
an axially wounded air-cored coil fixed on a mechanical support, so that said magnet can rotate in said axially wounded air-cored coil,
wherein bearings are placed between said second shaft and said second mechanical part so as to allow transmission of a torque to said blades through tilting of said magnet and said first mechanical part caused by a magnetic field generated by said axially wounded air-cored coil.
