Abstract

The present invention relates to the field of fluid machines. In particular, the present invention concerns a centrifugal electric pump (1) for suction of aeriform fluids comprising: - an electric motor (2) provided with a rotating shaft (3); - a suction body (4) provided with an intake (5) for the aeriform fluid and with at least one exhaust port (6); - at least one fan (8), fitted onto said shaft (3) and driven in movement by said motor (2), adapted to draw in a flow of air from said intake (5), spin it and discharge it outside said suction body (4) through said at least one exhaust port (6), wherein said electric motor (2) comprises: - a rotor with windings (9); - a stator (10) adapted to create a magnetic field inside which said rotor (9) rotates, and wherein said stator (10) is of the type with permanent magnets and said rotor (9) rotates at a high number of revolutions.
