Abstract

An electric fan (1) comprises a blade impeller (6, 8) and an electric motor with a rotor part (11, 12) including a plurality of permanent magnets (12) fixed to a peripheral ring (19) of the impeller (6), and a stator part (28, 31) which faces a portion of the said ring (11) of magnets (12) of the rotor and which comprises a winding (31) and a support structure (2;20) in which the impeller (6) is rotatably mounted and to which the stator part of the motor is fixed.
The support structure comprises a bracket (20) of generally elongate form having a first end (20a) provided with rotation support means (21) for the impeller (6) and a second end (20b) to which the stator part (28-31) of the electric motor is fixed.
