Abstract: An electric machine includes a casing, a cap covering the casing to define an enclosure, a heat sink, a circuit board in the enclosure having a first conductive layer as a top face, a second conductive layer as a bottom face, and vias passing through the circuit board between the top and bottom faces. An electronic component is soldered to the circuit board on the first conductive layer and disposed on top of a first part of the vias. A conductive mass is soldered to the circuit board proximal to the electronic component and disposed on top of a second part of the vias. The conductive mass forms part of the circuit through which a power supply of the electric machine flows and is in electric and heat exchange relationship with the electronic component, while the bottom face is in heat exchange relationship with the heat sink.

Abstract: An axial fan includes a motor, an impeller and a hub of the impeller for connecting to a shaft of the motor. A bottom wall of the hub has a central portion and an outer annular portion connected to the central portion by an intermediate portion defined by a plurality of blades arranged radially and angularly distributed about an axis of rotation. The blades are elasto-plastic blades and are able to prevent the impeller from moving axially parallel to the axis, moving radially perpendicular to the axis and a bending of the impeller with movements normal to the plane in which the mean surface of the impeller itself lies. The blades allow a movement with torsional bending around the axis to allow the damping of the resonance frequencies of the assembly formed by the impeller-shaft-rotor.
