bearing screen vibration

An Analytical Approach to Solving Motor Vibration Problems

with 2 times rotational vibration. Problems in a motor such as a rub, loose parts, a bent shaft extension or elliptical bearing journals can cause vibration at 2 times rotational frequency. Due to it''s closeness in frequency to twice line frequency vibration the two levels will add when they are in phase and
