#### Vibrational Issues Machine Service, Inc.

Critical speed vibrations. Critical speed occurs when a drive shaft rotates too fast for its length. It is a function of its rotating speed and mass and it is the RPM where a drive shaft starts to bend off of its normal rotating centerline. As a drive shaft bends, it does two things: It gets shorter.

#### Difference between base speed and rated speed of

Base speed is Hz multiplied by 60 then divides the result by half the number of poles. Rated speed is the base speed minus the slip at full rated load. An induction motor slows as it is loaded. The induction motor must run at a speed below the revolving stator field flux. Forward motion is due to the current flowing in the cage winding.
