摘要： A blower assembly includes a centrifugal fan and a motor assembly. The centrifugal fan has a plurality of axially extending impeller blades, a first axial end, and an air inlet. The air inlet is at the first axial end of the centrifugal fan. The motor assembly comprises a stator, a rotor, and an air directing surface. The air directing surface is shaped and configured to direct air drawn into the air inlet radially outwardly toward the impeller blades. The air directing surface extends generally along the rotor axis from its first end to its second end. At least a surface region of the air directing surface generally circumscribes the rotor axis and diverges radially outwardly as such surface region of the air directing surface extends away from the first end toward the second end.
