Integrally molded motor isolation system
View Patent ↗A heating, ventilation and air conditioning system includes a housing presenting an opening defining a rim surrounding a motor. A plurality of supports extend from the motor and a plurality of posts extend axially between a first end and a second end and interconnect the supports and the housing. The first ends of each post are supported by one of the supports and the second ends are supported by the housing with each of the posts being flexible for allowing for bending of the posts between the first end and the second end to allow for movement of the motor relative to the housing. In one embodiment, the first ends are upper ends and the second ends are lower ends and the housing includes an extension extending downwardly and a ledge extending radially inwardly. In another embodiment, the first ends are lower ends and the second ends are upper ends integral with the rim.

an opening defined within said housing,
a plurality of mounting supports extending from said motor for mounting said motor on said housing,
a plurality of posts extending axially between said supports and said housing for supporting said motor, wherein each of said plurality of posts includes a first end and a second end axially spaced from said first end,
characterized by said first end of each post being supported by one of said supports and said second end of each post being supported by said housing, wherein each of said posts being sufficiently flexible for allowing for bending of said post between said first end and said second end by said housing allowing movement of said motor relative to said housing for dampening vibrations of said motor.
2. A system as set forth in claim 1 further defined by said supports being spaced from one another circumferentially about said axis.

7. A system as set forth in claim 6 including an intermediate extension extending downwardly from said rim in radially spaced relationship to each of said posts and a ledge extending radially inwardly from said extension to said lower ends of said posts for supporting each post by said housing.
8. A system as set forth in claim 7 further defined by said extension being integral with said rim and said ledge being integral with said extension and said lower ends of said posts being integral with said ledge.
9. A system as set forth in claim 8 including a mechanical connection between said upper ends of said posts and said supports.
10. A system as set forth in claim 8 including a motor casing depending from and integral with said ledge of said extension and extending across said bottom end of said motor.
11. A system as set forth in claim 10 including a stabilizer interconnecting said bottom end of said motor and said casing.
12. A system as set forth in claim 8 wherein said extension is mechanically connected to said rim and said ledge is integral with said extension.
13. A system as set forth in claim 12 including a cage surrounding and supporting said motor, said supports being integral with said cage and integral with said upper ends of said posts, said lower ends of said posts being mechanically connected to said ledge.
14. A system as set forth in claim 5 further defined by said first ends of said posts being lower ends and said supports disposed at said lower ends, said second ends of said posts being upper ends supported from said rim.
15. A system as set forth in claim 14 including a mechanical connection between said lower ends of said posts and said supports.
16. A system as set forth in claim 14 further defined by said supports being mounted at a position between said top end of said motor and said bottom end of said motor.
17. A system as set forth in claim 14 including a guide extending upwardly from and integral with said rim for limiting radial movement of said motor.
18. A system as set forth in claim 17 further defined by said posts being integral with said rim and said rim being integral with said guide.
19. A system as set forth in claim 14 including a foam seal disposed circumferentially about said motor between said extension and said motor and axially between said supports and said rim for sealing said housing about said motor.
20. A heating, ventilating and air conditioning (HVAC) system comprising;
a housing having an inlet for receiving air and at least one outlet for delivering air,
a motor disposed in said housing and having an axis extending between a top end and a bottom end for driving a blower to move air through said housing,
a heat exchanger system disposed in said housing for conditioning air moving through said housing,
wherein said housing includes a rim defining an opening disposed about said axis,
three mounting supports extending from said motor and spaced from one another circumferentially about said axis for mounting said motor from said rim,
three posts each extending axially between a first end and a second end and disposed between said supports and said rim for supporting said motor,
each of said posts having a solid plastic circular cross-section, and
characterized by said first end of each post being supported by one of said supports and said second end of each post being supported by said rim with each of said posts being sufficiently flexible for allowing for bending of said post between said first end and said second end allowing movement of said motor relative to said housing while dampening vibrations of said motor.
21. A system as set forth in claim 20 including;
said first ends of said posts being upper ends and said supports being disposed at said upper ends and said second ends of said posts being lower ends supported by said rim,
