Abstract
An air mover, such as a cooling fan, comprises a motor and an impeller which is driven by the motor to generate a flow of air through a flowpath. The motor comprises at least one inlet opening and at least one outlet opening, each of which is in fluid communication with the flowpath. In operation of the air mover, a pressure difference between the inlet and outlet openings causes a portion of the flow of air to flow into the inlet opening, through the motor and out the outlet opening to thereby cool the motor.
