This paper reviews these unique capabilities, which can be broadly categorized as: elimination of wear; elimination of sealing and lubrication systems; reduction or elimination of transmitted noise and force; use as instrumentation systems; and thermal capabilities. When combined, these capabilities can provide high reliability and availability in challenging applications. The paper goes on to consider how a challenging application or environment may affect the design of a magnetic bearing system and the use of these capabilities. Examples of such applications within the author's own company are presented together with a brief review of some of the available literature.展开更多
