Abstract
An open frame motor is coupled to an output shaft rotatable about an axis, and has an axially front end and an axially rear end. An impeller is mounted on the shaft and rotated about the axis to drive air radially outward. A housing has an air flow inlet, an air flow outlet, and a closed inner wall surface. The inner wall surface extends from the inlet to the outlet and surrounds the motor and the impeller. The inner wall surface is located radially outward of the impeller axially from a first location forward of the impeller to a second location rearward of the front end of the motor. The inner wall surface defines a peripheral boundary of an air flow path extending alongside the impeller and the motor from the first location to a third location rearward of the motor to cool the motor.
