<p>A fan (10) and electric motor (12) combination which provides improved cooling for the motor, using a centrifugal impeller including rotating impeller blades (24). The impeller blades span between an impeller inlet and an impeller outlet, and they rotate to assist cooling for the motor. Cooling airflow is also assisted by the position of the impeller in that the impeller outlet is positioned upstream of the intersection of the impeller fan blade trailing edge (92) and the hub (20).</p> |
