    Abstract - (Show below) - (Hide below)

    Describes 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.

    Scope - (Show below) - (Hide below)

    This part of ISO14839: 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; identifies the primary similarities and differences between AMB systems and conventional mechanical bearings; NOTE This information helps AMB system users better to understand the selection process and implications of transition to AMB technology. identifies the environmental factors that have significant impact on AMB system performance; identifies the operating limitations that are unique to AMB systems and defines standardized methods of assessing these limitations; identifies typical mechanisms for managing these limitations, especially rotor unbalance; provides considerations for the design and performance of touchdown bearing systems; defines a typical signal set for provision in an AMB system for proper system/process interface as well as condition and diagnostic monitoring; details current best practices for monitoring, operation and maintenance to achieve highest operational system reliability; identifies typical fault-handling practices; recommends inspection and preventive maintenance processes for AMB systems.
