1 Scope
This part of ISO 14839:
-
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;
-
b) 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.
-
c) identifies the environmental factors that have significant impact on AMB system performance;
-
d) identifies the operating limitations that are unique to AMB systems and defines standardized methods of assessing these limitations;
-
e) identifies typical mechanisms for managing these limitations, especially rotor unbalance;
-
f) provides considerations for the design and performance of touchdown bearing systems;
-
g) defines a typical signal set for provision in an AMB system for proper system/process interface as well as condition and diagnostic monitoring;
-
h) details current best practices for monitoring, operation and maintenance to achieve highest operational system reliability;
-
i) identifies typical fault-handling practices;
-
j) recommends inspection and preventive maintenance processes for AMB systems.
