The present invention relates to a device for directly controlling a blade which comprises a stator (1), at least one blade carrier (7) composed of at least one curved magnet (6), the blade carrier (7) being secured to at least one blade (3) and pivotally coupled to the rotor (8) for varying the alpha angle of said blades with the excitation of the stator (1). The stator (1) is a partially spherical stator, the stator core (1) being the intersection of the blade axis (22) and the rotor axis (20), said stator being radially close to the magnets (3) to control the rotation of the blades (3) around the blade axis (22). A magnetic ring (5) holds the blades (3) in a neutral position, the system can be compared to a cyclically controlled mechanical oscillator, the frequency, phase and amplitude of the oscillation being controlled by said stator. Device providing a compact, lightweight and robust solution for controlling the direction of an aircraft.
