ISO 14839-4

Abstract

This part of ISO 14839: <br>a) indicates a typical architecture of an active magnetic bearing (AMB) system so that users can understand which components are likely to comprise such systems and which functions these components provide; <br>b) identifies the primary similarities and differences between AMB systems and conventional mechanical bearings; <br>NOTE This information helps AMB system users better to understand the selection process and implications of transition to AMB technology. <br>c) identifies the environmental factors that have significant impact on AMB system performance; <br>d) identifies the operating limitations that are unique to AMB systems and defines standardized methods of assessing these limitations; <br>e) identifies typical mechanisms for managing these limitations, especially rotor unbalance; <br>f) provides considerations for the design and performance of touchdown bearing systems; <br>g) defines a typical signal set for provision in an AMB system for proper system/process interface as well as condition and diagnostic monitoring; <br>h) details current best practices for monitoring, operation and maintenance to achieve highest operational system reliability; <br>i) identifies typical fault-handling practices; <br>j) recommends inspection and preventive maintenance processes for AMB systems.
