The critical speed range is the range of speeds over which the rotor shifts so as to rotate about
its center of mass. Passing through the critical speed range is characterized by some vibration.
†
Relative Centrifugal Field (RCF) is the ratio of the centrifugal acceleration at a specified
2
ω
radius and speed (r ) to the standard acceleration of gravity (g) according to the following
formula:
where r is the radius in millimeters,
60), and g is the standard acceleration of gravity (9807 mm/s
