Abstract: 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.

Abstract: A stator assembly includes an annular body extending about a central axis and a plurality of stator teeth extending axially from the annular body and spaced circumferentially about the annular body. The stator assembly includes at least one conduction coil and at least one bobbin configured to support the at least one conduction coil. The at least one bobbin is coupled to a first stator tooth such that the at least one conduction coil extends about the first stator tooth. The stator assembly further includes at least one insulation member configured to couple to a second stator tooth and extend into a slot between the second stator tooth and the at least one conduction coil. The at least one insulation member includes an end wall configured to cover the distal end of the second stator tooth when the at least one insulation member is coupled to the second stator tooth.

Abstract: A centrifugal blower assembly includes a scroll wall, a pair of opposing sidewalls, and an adjustable 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. The blower outlet defines a blower outlet area. The adjustable cutoff plate is adjustably positioned within the cutout to define a notch defining a notch area. The notch area and the blower outlet area define a total blower outlet area.

Abstract: An insulation member for a stator assembly includes a first portion configured to couple to a first stator tooth and a second portion movably coupled to the first portion. The insulation member has a first configuration and a second configuration. The second portion is configured to move relative to the first portion when the insulation member moves between the first configuration and the second configuration. The second portion is configured to extend adjacent a second stator tooth when the first portion is coupled to the first stator tooth and the insulation member is in the second configuration.

Abstract: A forward curved blower wheel has fan blades having relatively small leading edge blades angles and a relatively lengthy mean camber lines. The blower wheel also comprises leading edge notches adjacent its blower wheel inlet. The leading edge notches eliminate buffeting that would occur with such blades if such notches were not present.
