Abrégé

The present invention refers to a centrifugal fan assembly (1) of the plug fan type, comprising a blade group (2) that comprises an impeller (20) with a radial or mixed flow; and a motor group (3) operatively connected to the blade group (2) to rotationally drive it up to a maximum design speed, preferably equal to 3600 rpm. The motor group (3) comprises a static drive shaft (37) extending along the axis (X-X), and a brushless electric motor (30) that comprises a stator (31) supported by the drive shaft (37), and a rotor (32) connected to the blade group (2) rotating about the drive shaft (37). The rotor (32) comprises a plurality of magnets (321), wherein each magnet (321) comprises lateral sides that are inclined with respect to the axis (X-X) by a skew angle (a) between 1.5 and 10.5 degrees, preferably between 3 and 9 degrees.
