Mechanical vibration -- Vibration of rotating machinery equipped with active magnetic bearings -- Part 3: Evaluation of stability margin
This standard was last reviewed and confirmed in 2016. Therefore this version remains current.
ISO 14839-3:2006 establishes the stability requirements of rotating machinery equipped with active magnetic bearings (AMB). It specifies a particular index to evaluate the stability margin and delineates the measurement of this index.
It is applicable to industrial rotating machines operating at nominal power greater than 15 kW, and not limited by size or operational rated speed. It covers both rigid AMB rotors and flexible AMB rotors. Small-scale rotors, such as turbo molecular pumps, spindles, etc., are not addressed.
ISO 14839-3:2006 concerns the system stability measured during normal steady-state operation in-house and/or on-site.
ISO 14839-3:2006 does not address resonance vibration appearing when passing critical speeds. The regulation of resonance vibration at critical speeds is established in ISO 10814.
