Problems solved by technology

Locating the motor adjacent to or extending partially into one of the air inlet openings of the blower housing restricts air flow through the inlet opening, thereby making the blower assembly inefficient
Additionally, the impeller fan's circular plate that connects the fan to the motor shaft restricts the free flow of air through the interior of the impeller fan, thereby also causing inefficiency in the blower assembly

Embodiment Construction

[0035] The blower assembly of the present invention basically includes a blower housing 12, a motor 16 and a fan 14 contained within the blower housing.

[0036] The blower housing 12 has an outer wall 18 having a rolled length extending from a first end edge 22 of the outer wall to an opposing second end edge 24 of the outer wall. Such as Figure 3-8 As best shown, the first end edge 22 of the outer wall forms the boundary of the blower housing. Additionally, the first end edge 22 and the second end edge 24 of the outer wall 18 define opposite sides of a rectangular outlet opening 26 of the blower housing.

[0037] The blower housing also includes a first side wall 28 and a second side wall 32 . Portions of the perimeter of the two side walls 28 , 32 are connected to opposite sides of the outer wall 18 as shown in the figures. The first side wall 28 and the second side wall 32 also have respective straight edge portions 34 , 36 . The straight edge portions 34, 36 of the t...

Abstract

A blower comprises a blower housing, a fan, a motor and a support member. The blower housing has an air outlet opening. The fan is within the blower housing, the fan is adapted for rotation about a fan axis. The motor has a stator and a rotor. The rotor is rotatably coupled to the stator for rotation about the fan axis. The rotor and fan are coupled such that the fan rotates with the rotor. The support member is connected between the stator of the motor and the blower housing and extends generally radially from the fan axis. The support member supports both the motor and the fan.

Description

technical field [0001] The present invention relates to a blower assembly for an air handler in which an electric motor is integrated into the construction of the impeller fan and blower housing of the blower assembly. More particularly, the present invention relates to a blower assembly in which an axial flux motor has a stator integrated into the construction of the assembly's blower housing and a rotor integrated into the construction of the assembly's impeller fan. Background technique [0002] A typical configuration of a blower assembly for an air handler such as a boiler includes a fan turned by an electric motor and a blower housing housing the fan. [0003] A typical blower housing includes a rolled outer wall and a pair of side walls connected to opposite sides of the rolled outer wall. The outer wall has opposite ends positioned on opposite sides of the outlet opening of the blower housing. Side walls are also positioned on opposite sides of the outlet opening. ...
