Symptoms: 2x Lf 100hz Peak radial - SoftFoot (Stator Eccentricity)
Soft foot and warped bases can produce an eccentric stator. Altering the tension on the hold down bolts, or repairing the foundation can resolve this problem.
SoftFoot (Stator Eccentricity) is characterised by:
Spectrum: The peak at 2xLF will be high. For a two-pole motor this peak will be close to 2X running speed – you will need sufficient resolution to separate them.
We expect to see a high peak in the spectrum at 1X turning speed of the shaft. It is often higher in the horizontal direction compared with the vertical direction due to stiffness.
