Abstract
A motor assembly is disclosed in which a motor is rotationally connected to an impeller for producing a fluid flow, preferably an air flow. A venturi passage is provided for conducting a high velocity air jet from the air flow. A baffle is configured to the venturi passage to draw an air wash over the motor to provide cooling, without a separate cooling fan.
