Abstract
The electric fan assembly includes an electric motor composed of a rotor (11) having a fan wheel (12), and a stator (10) fitted with a card (50) supporting a printed circuit for determining operation of the motor. The stator includes a bearing (60) having two main opposite faces, a lower face and an upper face, for mounting the stator (10), defines a seat (62) for the assembly formed by the card (50) and a plurality of MOSs (54) projecting from the edges of the card, where the MOSs are coplanar to the card. The seat (62) has a depth dimensioned to receive a layer of solidifying resin covering and protecting the printed circuit and the relevant connections. The stator bearing (60) is axially crossed by channels (65) providing electric connection between the stator winding leads (30) and electric contacts (52) located on the card (50) proximate to an opening (51) obtained in the card at the channels (65). Axial fins (31) extend from the upper face of the stator bearing (60) for engaging the stator (10) axially and radially.
