Abstract
A centrifugal electric pump (1) for suction of aeriform fluids includes: 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 the shaft (3) and driven in movement by the motor (2), adapted to draw in a flow of air from the intake (5), spin it and discharge it outside the suction body (4) through the at least one exhaust port (6), wherein the electric motor (2) includes: a rotor with windings (9); a stator (10) adapted to create a magnetic field inside which the rotor (9) rotates, and wherein the stator (10) is of the type with permanent magnets and the rotor (9) rotates at a high number of revolutions.

A centrifugal electric pump (1) for suction of aeriform fluids comprising:
- an electric motor (2) of by-pass type 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) belonging to the same suction body (4);
- 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,
- characterized in that said stator (10) is of the type with permanent magnets and said rotor (9) rotates at a high number of revolutions.
