Motor/fan assembly having a radial diffuser bypass

A bypass motor assembly, comprising:

• a motor having a rotatable shaft;
• a working air fan secured to said rotatable shaft;
• a shroud having an intake eyelet and at least one exhaust aperture;
• an end bracket having a shaft hole through which said shaft extends, said end bracket and said shroud partially enclosing said working air fan, wherein rotation of said working air fan draws air in through said intake eyelet and exhausts the air through said at least one exhaust aperture;
• said end bracket having a plurality of vanes that form a fan chamber that receives said working air fan such that air expelled by said working air fan is re-directed by said vanes toward said at least one exhaust aperture;
• and
• wherein said end bracket has a sloping shoulder such that said vanes slope in a corresponding manner.

• and
• wherein each said vane has a top edge extending between a leading end to a trailing end, and wherein said shroud is in touching contact with at least a portion of said top edges.

A bypass motor assembly, comprising:

• a motor having a rotatable shaft;
• a working air fan secured to said rotatable shaft;
• a shroud having an intake eyelet and at least one exhaust aperture;
• an end bracket having a shaft hole through which said shaft extends, said end bracket and said shroud partially enclosing said working air fan, wherein rotation of said working air fan draws air in through said intake eyelet and exhausts the air through said at least one exhaust aperture;

• wherein vanes adjacent each other form channels therebetween;
• and
• wherein said shroud is in touching contact with each said vane proximal said leading ends so as to enclose at least a portion of each said channel.

A bypass motor assembly, comprising:

• a motor having a rotatable shaft;
• a working air fan secured to said rotatable shaft;
• a shroud having an intake eyelet and at least one exhaust aperture;

• and
• wherein said plurality of vanes each have a trailing end that with said shroud form a gathering chamber, said gathering chamber logarithmically expanding toward said single tangential exhaust aperture.

A bracket for a bypass motor assembly which includes a tapered working fan rotated by a motor shaft, wherein the tapered working fan is partially enclosed between a shroud having at least one vent and the bracket, the bracket comprising:

• a base having a periphery that is adapted to be sealed by the shroud;
• a shoulder extending from said periphery;
• and
• a plurality of vanes extending from said shoulder, said plurality of vanes facilitating movement of air expelled by the tapered working fan out the vent.

A motorized fan assembly, comprising:

• an end bracket with a rotatable shaft therethrough;
• a shroud having an intake eyelet and at least one exhaust aperture, said shroud enclosing said end bracket;
• a fan connected to said rotatable shaft, and rotatably received between said end bracket and said shroud;
• and
• an air intake seal disposed between said shroud and said fan, wherein said air intake seal comprises a seal strip secured to an underside of said shroud around said intake eyelet.
