Abstract
A fan unit for cooling an internal combustion engine comprising a fan impeller associated with a coaxial channel for guiding the air travelling through said impeller and an electric driving motor of DC type. The channel is fixed to the ends of the blades of the impeller and rotates with the impeller and itself constitutes the rotor of the electric motor whose stator coaxially surrounds at least a part of the channel. The stator is rigid with a fixed shaft around which the impeller rotates. This fan unit has a high permeability when inoperative so that it is particularly adapted for use in an automobile vehicle.
