Over thirty years after their first commercial application, magnetic bearings are making inroads into larger and more demanding industrial machines. Product maturity has allowed the successful use of these bearings in dozens of applications where reliability, operational flexibility, availability and maintainability are important considerations.

These applications now include steam turbine generators and motor compressors with rotor weights exceeding 10 tons and power ratings in excess of 20 MW. Comprehensive feasibility studies for applications to 100 MW and higher demonstrate that the trend to larger and higher-powered machinery will continue.
