    Abstract: In one aspect, a motor assembly is provided. The motor assembly 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

    Abstract: 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.
