Machinery Vibration Limits#8

levels of vibration are indications of condition except where structural resonances (e.g.: bearing housings, or motor bases) amplify vibrations at certain frequencies (usually integer multiples of shaft speed). Dynamic response at vibration test points can be measured on new installations to assist in establishing standards for absolute vibrations.

Motor Vibration Analysis: Keeping it Simple | Electrical ...

There's typically no way around it. At some time during a motor's life, it is likely to experience high vibration levels. What's behind this maintenance phenomenon? The cause may be an electromagnetic or mechanical imbalance, loose components, rubbing parts, bearing failure, or resonance. When a problem occurs, it is critical to quickly identify the source of the trouble and

ISO 10816 Vibration Severity Standards

ISO 2372 (10816) Standards provide guidance for evaluating vibration severity in machines operating in the 10 to 200Hz (600 to 12,000 RPM) frequency range. Examples of these types of machines are small, direct-coupled, electric motors and pumps, production motors, medium motors, generators, steam and gas turbines, turbo-compressors, turbo-pumps and fans.
