The wind motor (1) is of the type comprising a rotor (2) with a swivel-mounted hub carried by a nacelle (5) on which a sensor (8) for the yaw angle ( delta ) is disposed upwind of the rotor (2); first means (15, 19) enable the cyclic pitch of the rotor (2) to be set and varied continuously by differentially varying the setting angles of the blades (3), and, when a yaw angle exceeding a predetermined value is sensed, second means (29, 35) under the control of the sensor (8) then control the first means in such a manner as to cause the plane or rotation of the rotor (2) to rotate relative to the nacelle (5) by aerodynamic effect, in a direction concordant with the yaw angle ( delta ).
