A motor cooling and sound absorbing system includes a housing (10) forming a chamber (13) around a motor (11). The shaft (12) of the motor (11) carries a fan (40) positioned in a chamber (38) formed by a recess (36) cut in a foam block (35). The fan (40) draws air into the chamber (13) through inlet apertures (33) in the housing (10) and this air is directed past the motor (11) to cool it. The air exits the fan (40) generally radially against an angled surface (37) of the recess (36) of the foam block (35). The air is then received in a diffuser passageway (41) defined by the angled surface (37) and an angled surface (42) of a choke plate (19) positioned above the foam block (35). The diffuser passageway (41) reduces the velocity of the air to assist the foam block (35) in absorbing the noise generated thereby, while at the same time reducing the pressure at the exit of the fan (40) to increase the cooling air flow past the motor (11). The air then passes from the diffuser passageway (41) to a plenum chamber (43) located above the foam block (35) and out elongate slots (26) formed in the bottom of the housing (10).
