A motor-driven fan includes an electric motor including a rotor and a stator in which the rotor includes an essentially cup-shaped cap which extends at least partly around the stator and has a plurality of lateral exit openings adjacent the bottom wall, and an impeller or fan including a hollow hub from which extends a plurality of main outer fan blades. This hub has a front wall fixed to the back wall of the cap of the rotor and a lateral skirt which surrounds the lateral wall of the cap in a radially spaced relationship. The hub is further provided with inner ventilation blades acting in operation to generate a cooling air stream which passes through the motor.
