An assembly for moving a fluid includes: a housing having an inlet and an outlet; a first shaft member fixedly coupled to the housing, the first shaft member having a central axis; a stator assembly fixedly coupled to the housing, disposed around the central axis and spaced radially outward from the first shaft member; and a driven assembly. The driven assembly includes: a second shaft member having a first end, a second end, and a cylindrical cavity defined therein extending inward from the first end; a magnetic ring fixedly coupled to the second shaft member at or about the first end; and an arrangement fixedly coupled to the second shaft member at or about the second end. A bearing system is disposed between the first shaft member and the second shaft member such that the driven assembly is rotatably coupled to the first shaft member.

A centrifugal blower assembly includes a scroll wall, a pair of opposing sidewalls, and a cutoff plate. The scroll wall is positioned between the pair of opposing sidewalls such that the scroll wall and opposing sidewalls together define a blower chamber and a blower outlet. The scroll wall extends circumferentially between a cutoff point to an end point and defines a cutout extending circumferentially from the cutoff point. The scroll wall, the pair of opposing sidewalls, and the cutoff point define a blower outlet, wherein the blower outlet defines a blower outlet area. The cutoff plate extends circumferentially from the end point. The cutoff plate defines a notch defining a notch area, the notch area and the blower outlet area define a total blower outlet area, wherein the notch includes a center portion that defines a portion of an elliptical shape.

Disclosed herein are embodiments of magnetically controlled valve and pump systems that can be used to control and facilitate fluid flow in fluidic devices. Various types of magnetically controlled valves and pumps are described as well as methods of magnetically-controlling such valves and pumps.

An electric powered lint blower that includes a housing body having an air intake and outlet, the outlet designed to force air flow through a tube connected to the blower housing and out through the dryer vent exhaust of a building structure. The housing further comprising a detachable component part having an intake opening to receive air flow from a clothes dryers, exhaust vent, and intake opening to receive air from the External Dryer Vent Lint Blower and an opening to expel air into the dryer exhaust vent of a building or structure. The electric motor comprising an attached impeller to generate a powerful air flow. A power supply cord. A second power cord attached to control the power—on/off positions of a power ON/OFF switch.

A gas compression system and a method of flow conditioning by a gas compression system are provided. A gas compression system includes a compact flow conditioner in a form of a flow conditioner tank and a combined multi-phase pump and compressor unit comprising an impeller configured to compress a mixture of gas and liquid, wherein the gas compression system is configured such that the gas and the liquid are separated in the flow conditioner tank, the separated gas and liquid are sucked up through the separate gas and liquid pipes and re-mixed again upstream of the impeller, and the liquid is distributed in a gas flow by Venturi effect, and wherein the Venturi effect is obtained by a constriction in the outlet pipe to the impeller, just upstream of the impeller.

A fan assembly having a reduced dimension formed by several modifications is described. The fan assembly includes a stator having stator coils positioned within a recessed portion of a pillow that receives the motor. The stator may include wire connections positioned between adjacent stator coils and designed to terminate wires of the stator coils. The wire terminations may be on a protrusion or a post positioned between adjacent stator coils, or alternatively, the wire terminations may be disposed on protruding features of a bushing. The protrusion may be formed from an electrically conductive material and electrically connected to a motor control circuit via a flexible printed circuit. In some embodiments, the protrusion is part of an electrically neutral stator bushing having several pins. Also, a gap region between the bushing and a flange feature is designed to improve an adhesive joint.
