vibration the two levels will add when they are in phase and subtract when they are out of phase and then add again when they return to being in phase. This modulation will repeat at a frequency of 2 times the slip on 2 pole motors. Even at no-load, twice rotation vibration on 2 pole motors will vary from 7200 cpm (120Hz) due to slip.

Beginning Vibration Analysis with Basic Fundamentals

01-12-2014  It is the most common term used in vibration analysis to describe the frequency of a disturbance. Never forget the 1 cycle / second relationship ! Traditional vibration analysis quite often expresses frequency in terms of cycle / minute (cpm). This is because many pieces of process equipment have running speeds related to revolutions / minute (rpm).

• Measure the distance between the scribed mark and the outside bearing housing lip. In the case that the magnetic center scribe mark falls inside the motor housing while at rest, scribe a mark in the rest position. While the machine is un-coupled run the motor and estimate the difference between the newly scribed mark and the magnetic center mark.
