Abstract
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.
