These guidelines are presented in terms of both steady-state running values of these indices and any magnitude changes which may occur in these steady-state operations.<\/p>\n<p>This part of ISO&nbsp;14839 is applicable to industrial rotating machines generating or consuming nominal power greater than 15&nbsp;kW, and is not limited by size or operational rated speed (i.e. comprising turbo-compressors, turbo-pumps, steam turbines, turbo-generators, turbo-fans, electric drives and other rotors supported by AMBs). This part of ISO&nbsp;14839 establishes the vibration, current and voltage evaluation of the rotating machinery equipped with AMBs, specified by a comparatively large power capacity as described above, excluding small-scale rotors such as turbo-molecular pumps, spindles and flywheels.<\/p>\n<p>This part of ISO&nbsp;14839 covers both AMB-equipped rigid rotors and AMB-equipped flexible rotors.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Mechanical vibration.
