Hi all - In one of the motor at site, the eccentricity plot of the rotor has increased drastically after a certain rpm.
could this cause any issue in the long run?
This test was done at no-load, solo run before commissioning. Shaft Vibrations and temperature are within the limits.
This is a 2P-IC611 type motor. Self cooled bearings.
