摘要： An axial flow fan comprises a hub rotatable on a central axis and a plurality of radial blades extending from the hub, each having a root portion adjacent the hub and each having tip portion space radially from the hub and surrounded by an annular band. The root portions are substantially equally spaced circumferentially at their junctions with the hub and at least some of the tip potions are substantially unevenly space circumferentially. The latter is due to the condition that blade centerlines are pivoted through unequal angles about points along the junctions between the hub and the blade root portions.

摘要： A motor stator mounting device includes a plastic motor housing having a cylindrical housing section for receiving the stator. Longitudinal ribs along an inside surface of the housing section are inclined to converge gradually in a distal direction, thus tending to center a stator inserted distally into the housing section. An annular stator retaining member includes a plurality of distally extending centering features. Outside surfaces of the centering features interact with an interior surface of the housing section to center the retaining member as it is inserted distally. Inside surfaces of the centering features interact with a proximal region of a previously inserted stator, such that distal insertion of the retaining member both axially positions and radially centers the stator relative to the cylindrical housing. The retaining member is secured to the housing with a series of sonic welds to positionally fix the stator inside the housing.

摘要： An electric motor assembly includes a motor housing having a main body portion with a central plane bisecting the main body portion into an upper portion and a lower portion. The motor housing further includes a first printed circuit board support structure having a plurality of slots and a second printed circuit board support structure having a top surface that is orientationally above at least a portion of the plurality of slots. The motor assembly further includes a printed circuit board having tabs which are configured and arranged to operably coordinate with the plurality of slots to thereby removably retain the printed circuit board at the motor housing and in contact with the top surface of the second printed circuit board support structure.
