A motor case assemblya permanent magnet D.C. electric motor includes a motor casehaving a generally cylindrical wall, a closed end, and an open endopposite the closed end, defining an interior. Permanent magnet structureis mounted to the wallin the interior. A surface defines at least one holethrough the wall. The holeis constructed and arranged to be employed in mounting the caseto a shroud to obtain a mass balance distribution of a motor shroud assembly.

Motor stator assembly mounting features for radial mounting to a shroud and assembly method

A fan shroud structure () is constructed and arranged to carry a fan and motor. The fan shroud structure includes a base () and an annular rim () extending from the base. The rim defines a generally central opening () sized to accommodate blades of a fan. Motor mounting structure () is coupled with the rim () and is disposed generally adjacent to the central opening (). The motor mounting structure () is constructed and arranged to support a motor for driving a fan. The fan shroud structure () includes a first pair of opposing sides () and a second pair of opposing sides () coupled to the base to form a box-like configuration defining a perimeter of the fan shroud structure raised with respect to the base such that the sides are discontinuous with respect to the base () to shift resonance of the shroud structure.

Fan shroud structure reinforcement to reduce or eliminate warping and distortion

A fan shroud structureis constructed and arranged to carry a fan. The fan shroud structure includes a bodyhaving a periphery, a main surface, and an annular rimdefining a generally central opening. The openingis sized to accommodate blades of a fan. Fan mounting structureis coupled with the body and is disposed generally adjacent to the central opening. The fan mounting structure is constructed and arranged to support a motor of a fan. The body includes a plurality of surfaces featuresconstructed and arranged to affect resonance of the shroud structure with each feature having a surfacethat is discontinuous with respect to the main surfaceof the body. Each featurealso extends from the annular rim to the periphery of the body.

Fan shroud structure for reducing resonance, improving stiffness and manufacturability

A fanincludes a central hub, an outer ring structure, and a plurality of fan blades. Each blade is of generally Y-shaped configuration having first and second separate branches, respectively, coupled to the huband merging with a third branch. The third branchis coupled to the ring structureat a tipof the blade

Low pressure fan with Y-shaped blades

A fanincludes a hub, a plurality of fan bladesattached to the hub at one end and extending outwardly from the hub, and a ringconcentric with the hub and coupled to tipsof the blades. A dimensionless radius (r/R) is defined from a center of the hub (r/R=0) radially outwardly, wherein each tip of the blades is r/R=1. A pitch ratio increases up to about r/R=0.85, and decreases in a range of about 0.85&#x3c;r/R&#x3c;1.0. In the range of about 0.6&#x3c;r/R&#x3c;1.0, a chord length decreases continually.
