Blower assembly with integral injection molded suspension mount
A blower assembly comprises a blower housing having a stator assembly integrally formed therewith. The stator assembly includes a stator bore having a rotor magnet rotatable therewithin such that the motor assembly is configured as a brushless D.C. motor. An impeller is mounted on a motor shaft of the motor assembly and has a plurality of vanes extending upwardly therefrom. Each one of the vanes has a vane height which is optimized to minimize the formation of fluid eddy losses during compression of air by the impeller. A bearing assembly rotatably coupling the rotor magnet to the stator assembly is sized and configured to maintain an air gap of approximately 0.0002 inches between the vanes and a housing interior surface of the blower housing during rotation of the impeller.
1. A blower assembly comprising:
a blower housing;
a motor assembly disposed within the blower housing and including a stator assembly and a rotor magnet;
an impeller rotatable with the motor assembly; and
at least one suspension mount extending laterally outwardly from a perimeter of the blower housing and being sized and configured to support the blower assembly, the suspension mount integrally formed with the blower housing by injection molding.
2. The blower assembly of claim 1 wherein:
the motor assembly is configured as a three-slot/two-pole brushless D.C. motor;
the stator assembly including a stator bore extending therethrough;
the rotor magnet being rotatable within the stator bore.
3. The blower assembly of claim 1 wherein the suspension mount is configured to attenuate vibrations generated during rotation of the impeller.
4. The blower assembly of claim 1 wherein the suspension mount is configured as a serpentine spring member.
5. The blower assembly of claim 4 wherein the suspension mount comprises three of the serpentine spring members angularly spaced about the perimeter of the blower housing.
6. The blower assembly of claim 5 wherein:
the blower assembly is adapted to be mounted on a mounting frame having at least one mounting slot;
the spring member having a free end sized and configured to be engaged to the mounting slot.
7. The blower assembly of claim 1 wherein:
the blower housing includes upper and lower housing portions engageable to one another at a perimeter joint;
the suspension mount extending outwardly from at least one of the upper and lower housing portions and being positioned adjacent to the perimeter joint.
