2017-3-17 Simply, vibration analysis is the primary method of keeping an eye on the health of your motor.” Along with vibration analysis, a heat analysis can also be done to check the surface temperature of bearings and the bearing assembly. If the bearings and assembly are showing excessive heat, then that is likely indicative of a problem.

2021-2-26 Pattern recognition is a key part of vibration analysis, but significant training and experience are necessary to recognize and read the patterns. Vibration analysis can watch bearing wear across 12 to 18 months as they go from slight wear (no action) to extreme wear (replace bearings immediately).

2017-10-11 Vibration Analysis Tests. Excessive vibrations are difficult to detect by hand, but can significantly shorten the life of your electric motor. This is because it can lead to failure of windings or metal fatigue of parts. Excessive vibration can be a result of a defective sleeve, improper balance, misalignments, or excessive belt tension.

2021-4-13 The electric motor operation is based on the following points: • At least one of the two magnetic field is generated by a solenoid carrying a current. • Phase relation between the rotor and stator magnetic field (i.e. the load angle) must be always greater than 0° in order to keep the motor in motion (negative angles reverse the rotation).

2021-4-27 Many vibration programs fail because they become too complicated. Too much data can sometimes become more confusing than too little data. Many potential machinery problems can be eliminated with the analysis if you keep in mind several simple concepts. Vibration units such as acceleration are more sensitive to high frequencies than low frequencies.
