摘要： A blower includes a housing including a proximal opening and a distal opening that are co-axially aligned, a stator component) provided to the housing, an impeller positioned between the proximal opening of the housing and the stator component, and a motor adapted to drive the impeller. The impeller includes a plurality of impeller blades. The stator component includes a plurality of air directing grooves along its exterior surface. The leading edge of the air directing grooves extend tangentially outwards from the outer tips of the impeller blades and are configured to collect the air exiting the impeller blades and direct it from a generally tangential direction to a generally radial direction by dividing the air from the impeller and directing the air along a curved path towards the distal opening so that airflow becomes substantially laminar.

摘要： A blower includes an electric motor case, a housing having a housing inlet and a housing outlet between which is defined a flow path for gas, a first impeller adapted to accelerate gas tangentially and to direct it radially outward, and a stationary portion. The stationary portion includes an annular gas flow path of sufficient width to allow a flow of gas therethrough without introducing excessive pressure drop. The stationary portion includes a first stator vane structure defining a plurality of stator vane leading edges, the first stator vane structure located on the second side of the motor and arranged to smoothly direct gas flow along a curved path. The motor case provides a shielding function for the stator vane leading edges from an impeller blade pressure pulse.

摘要： A method for making a poly-phase field winding for a slotless stator includes: forming the first coil group by winding an insulated wire for each coil winding in a first direction around a mandrel; axially shifting along the mandrel the insulated wire from a trailing edge of each coil winding a distance substantially equal to one half of twice the number of coil groups multiplied by the number of coil windings minus one times the width of one of the completed windings to position the wires at a leading edge of each of coil winding in the second coil group; forming the second coil group by winding the insulated wire for each coil winding in the first direction; removing the mandrel from the wound coil groups; collapsing the wound coil groups to a single layer web, and wrapping the single layer web into a cylinder to form the field winding.

摘要： An impeller and at least a portion of a cooperating peripheral volute may be integrated are integrally injection molded with, concentric outer rotor and inner stator assemblies, respectively, to achieve a low profile precision impeller mechanism based on an improved brushless D.C. motor with low length to diameter ratio and suitable for use in a variety of other applications. A rotating cap has an inner circumference which is molded about an outer ferromagnetic back ring that in turn supports a rotor magnet having a number of poles of alternating polarity and separated by a relatively small cylindrical air gap from a fixed stator assembly. The fixed stator assembly is integrally molded into a base housing having a bearing support that extends upwardly through the center of the stator assembly and that is rotatably coupled to a rotating shaft that extends downwardly from the center of the rotating cap.
