Abstract: There is disclosed a rotor for an aircraft capable of hovering, comprising: a stationary support structure; a rotative element, which is rotatable about a first axis with respect to said stationary support structure with a first rotational speed; at least one blade, which is operatively connected with said rotative element; and a transmission group, which comprises an output element rotatable about first axis with a second rotational speed different from first rotational speed.

Abstract: There is disclosed a rotor for an aircraft capable of hovering, comprising: a stator; a rotatable element, which is rotatable about an axis with respect to stator; a blade, which is connected with element; a support element, which supports a source of a magnetic field and is either stationary or driven in rotation at a first rotational speed; and a first electric circuit, which is angularly integral with element and can be driven in rotation at a second rotational speed different from first rotational speed; first electric circuit being electromagnetically coupled with source so that an electromotive force is magnetically induced in first electric circuit and an first electric current flows in first electric circuit; rotor further comprises a second electric circuit which is either stationary or driven in rotation at a first rotational speed, and a sensor generating a signal associated to a back electromotive force induced on second electric circuit.
