Embodiment Construction

[0042] refer to figure 1 , shows a centrifugal electric pump 1 for suction of a gas jet, equipped with a bypass-type motor 2 with permanent magnets according to a preferred embodiment of the invention.

[0043] Said electric pump 1 is essentially formed by an electric motor 2 provided with a drive shaft 3, a suction body 4 and one or more fans 8 adapted to move an air flow.

[0044] In the embodiment shown, said suction body 4 is cylindrical and comprises an annular base provided with a centrally placed suction opening 5, and side surfaces provided with a plurality of discharge openings 6, adapted to discharge the suction air flow without passing through the motor 2.

[0045] Said body 4 is actually closed at the top by a cover 7 which also serves as a base for said motor 2 .

[0046] The fan 8 is mounted on the drive shaft 3 and driven by the movement of the motor 2 .

[0047] special reference Figure 2-4 , which show details of the electric motor 2 with permanent magnet...

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.

Description

technical field [0001] The invention relates to the field of fluid working machines. [0002] In particular, the invention relates to centrifugal electric pumps for sucking gas jets, especially suitable for use in vacuum cleaners and floor cleaning machines for cleaning surfaces by sucking air containing dust or liquids, for domestic and industrial and professional use environment. Background technique [0003] Due to the very high rotational speeds of these electric pumps, they are commercially defined as "turbines", despite the fact that they are work machines. In fact, the number of revolutions goes well beyond 3,000 revolutions per minute (rpm), reaching 7,000-8,000 rpm and beyond. [0004] Centrifugal electric pumps of the conventional type for suctioning gas jets mainly consist of a motor with a high number of revolutions and a suction pump provided with a suction port for suctioning a liquid and for discharging the same liquid belonging to the same pump body discha...
