Summary:A fan (100) of a rotary electric machine comprising at least three blades (101) in which at least one property of the blades is, following the circumference of the fan in a given direction, gradual for at least three consecutive blades, the property being chosen from the group including: a spacing angle (102) between a straight line passing through a characteristic point (103) of a blade and an axis of rotation of the fan (104), and a straight line passing through a corresponding characterising point (105) 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 through two characteristic points of a blade and a straight line passing through two corresponding characteristic points of an adjacent blade.
