In one aspect, a centrifugal blower assembly is provided. The centrifugal blower assembly includes a housing defining an interior space and an impeller configured to channel an airflow within the interior space. A motor is coupled to the impeller and configured to rotate the impeller about an axis. The centrifugal blower also includes a plurality of mounting arms. Each mounting arm of the plurality of mounting arms includes a first end coupled to the housing and a second end coupled to the motor. Each mounting arm of the plurality of mounting arms has a cross-sectional profile that comprises a portion of an airfoil shape.

A motor assembly is provided that includes a fan housing having an air inlet and an air outlet, and a motor coupled to the fan housing and positioned within the air inlet. The motor includes a first end, a second end, and a shaft. The motor assembly further includes a fan coupled to the shaft proximate the motor second end. The motor first end includes a contoured surface having a stagnation point and a plurality of points along the contoured surface downstream of the stagnation point. Each point of the plurality of points has a coefficient of pressure less than 1, and the contoured surface is configured to direct air around the motor and to reduce airflow restriction and flow disturbance within the fan housing.
