Abstract
An air handler blower assembly includes a blower housing containing a centrifugal fan and a motor mounted on the blower housing and connected to the fan. The blower housing has opposite first and second air inlet openings that are coaxial with the fan, and the first inlet opening is larger than the second inlet opening. The motor is mounted on the blower housing with the motor extending axially through the first inlet opening into the blower housing and into the interior of the fan. The positioning of the motor inside the blower housing and inside the fan reduces the overall axial dimension of the blower assembly. The larger first air inlet opening reduces the losses associated with placing the motor in the first air inlet opening while keeping the second air inlet opening at a smaller size than the first air inlet opening avoids creating buffeting noise and a power/efficiency loss from occurring.
