Abstract: A fan assembly has a support structure and a motor fixed to the support structure. The motor has a stator, an outer rotor and a controller. Components of the controller are in a thermal exchange relationship with a plate-like heat sink at one end of the stator. A fan, fixed to the rotor, has a hollow hub from which blades extend. Air flows through inlet openings in a front wall of the hub. The heat sink has a slit with an outer side, axially offset from the inner side. A portion of the heat sink forms a wing deflecting part of the air flow coming from the inlet openings through the slit to pass over the surface of the heat sink.

Abstract: A voltage regulating device for an electric motor has programmable control and regulation circuits carried by a circuit board mounted in a sealed support casing. The circuits have at least one programming terminal which is accessible from outside the support casing to enable programming of the circuits without opening the support casing.

Abstract: An electronic control unit, has a casing accommodating a printed circuit board. The casing has a molded plastic intermediate structure having a frame. Two electrically conductive members are partially embedded in the intermediate structure during the course of molding and are connected to the printed circuit board forming output terminals of the control unit. Two flexible conductors, provided with corresponding electrically insulating coverings, connect the control unit to an apparatus to be controlled. Each conductor has an end permanently connected to a respective one of the conductive members and the connection between the conductors and the conductive members are covered and sealed in a fluid-tight way by an electrically insulating material.
