摘要

An alternative idea for the construction of active magnetic bearings, adapted from a successful structure used in split-winding self-bearing motors, has been recently discussed in the literature. A mathematical model for this bearing configuration is developed in this paper. Preliminary theoretical results predict a greater equivalent stiffness for this model, when compared with traditional active magnetic bearings. The use of recently built prototypes for testing if these expectations hold true is also discussed.
