A fan of a rotary electric machine. The fan has an axis of rotation and comprises a plurality of blades (). At least one characteristic of the blades is variable in the direction of a circumference of the fan around the axis of rotation for at least four consecutive blades. The at least one characteristic is selected from the group comprising a spacing angle between a straight line passing radially via a characteristic point of one of the blades and the axis of rotation of the fan and a straight line passing via a corresponding characteristic point of an adjacent blade and the axis of rotation of the fan, a height of the blade, a length of the blade, and an angle of inclination between a straight line passing via two characteristic points of a blade, and a straight line passing via two corresponding characteristic points of an adjacent blade.
