Oct 11, 2019 Fact Soft foot was found on a motor to change vibration overall from rough to good levels with a minor lift of only .002 . Soft foot can also be the source of high vibration spike at electrical frequency or 7200 CPM but much lower peak at 1x RPM. The reason is stress on the stator frame when there is uneven contact at all four motor feet.
