Mechanical vibration. Vibration of rotating machinery equipped with active magnetic bearings - Evaluation of vibration Ingestion-build-156411 BS EN ISO 14644-1:1999 Cleanrooms1 Scope This part of ISO 14839 sets out general guidelines for measuring and evaluating rotating machinery equipped with active magnetic bearings (AMBs) with respect to the following two indices: shaft vibratory displacement measured at or close to the AMBs, and working current and voltage measured in magnetic coils or power supply amplifiers. Both indices are measured under nominal operating conditions in house and or on site. These guidelines are
