Japanese Proposal for International Standardization for Active Magnetic Bearing

A basic design for an active magnetic bearing has successfully been developed and trials of it's application to actual rotating machines are expanding widely in many industrial fields. However, there are a few industrial field where AMB is the best option in the selection of a bearing for rotating machinery. Accordingly, Japanese experts have proposed international standardization for AMB to the ISO. The objectives of the standardization are as follows: (I) to serve as a design guide for AMB to achive compatibility, low priced products and wide-spread applications; (2) to provide vibration. and current criteria in commission and maintenance to rapidly resol ve conflicts between venders and users and to assure users safe operation; (3) and to define AMB terminology to promote mutual understanding between research engineers, development engineers, designers and users of AMB. JSMEI ATS 10-25 Technical Section for Standardization on Active Magnetic Bearing is preparing a draft on vibration criteria and terminology and will propose the draft at a meeting of the ISOITC I 08 in Sydney on 16 September 1996.This paper provides a draft of an initial list of terminology which contains nearly 100 relevant terms in English for AMB, and the fundamental ideas for the new regulation concerning the vibration of AMB equipped turbomachinery.
