The emerging development of magnetic bearings represents a new dimension in the continuing utility quest for improved plant operating reliability and reduced cost. While magnetic bearings have been used in specialized applications (e.g., centrifuges, space platforms) for some time, recent advances in computing technology now provide the basis for their wide-spread use in turbomachinery. While additional development is required, their ultimate potential is to eliminate bearing wear, provide enhanced control of shaft rotor dynamics, eliminate the generation of forces related to shaft imbalance, provide inherent on-line diagnostics of both the magnetic bearings and the equipment in which they are installed, and eliminate shaft seals in some applications. These guidelines have been developed through the Magnetic Bearing Advisory Committee. Their objective is to foster the commercial acceptance of magnetic bearings through improved communications, so that their benefits can be realized by utilities. The guidelines are written primarily for end-users: plant engineers, operations and maintenance personnel and plant managers, as well as related support personnel, such as architect engineers and consultants. Key topics addressed in these guidelines include an introduction to the principles of magnetic bearings, a review of relevant magnetic bearing experience, technical summaries of differences between magnetic and conventional bearings, suggested methods for technical and economic evaluations, project management considerations, and guidelines for their specification, procurement, installation, operation and maintenance.
