Vibe isolation for machine mounted on wood frame floor
Vibe isolation for machine mounted on wood frame floor
(OP)
I have a 3-phase converter installed on the 2nd floor of an older wood frame building. The phase converter is essentially a large electric motor which weighs about 400 pounds. The installer set it on a rubber pad with bolts running down into a piece of plywood attached to the wood frame floor. You can hear the vibration throughout the whole building.
How do I isolate the vibration? I am leaning to housed spring vibe isolation mounts. Should I also try to add some mass with a concrete pad or something?

Note that the usual approach is to only get as low a natural frequency that will just reduce the vibration to a tolerable level, to minimize the translational motions.

The design of the electrical connections will need to be reviewed.

And like other's said, look out for mechanical short circuiting that limits the free motion of the unit on the isolators.
