Abstract: A single-phase asynchronous motor (1) for a suction assembly of an extractor hood (5) comprises a stator (13) wherein a rotor is driven into rotation, a driving shaft (15) carrying a rotor (16) being integral with the latter for sucking smokes and vapors from a cooktop placed below the hood (5) and for sending them towards an output (8) of the hood, said stator (13) comprising a plurality of stator core laminations (22) provided with sixteen slots (30) containing metal electrical windings wherein current flows so as to generate a magnetic flux suitable for causing the rotation of the rotor. The stator has an outer diameter (D2) greater than 80 mm, the number of the slots (30) being sixteen, such slots having a unit surface of at least 70 mm2.
