Abstract:

Magnetic bearing design is an iterative process with many uncertainties. In this paper, many-to-many mapping relationships between the users' requir ements and parameters of design are given and the general design rules presented; moreover, the structural analysis of the magnetic bearing design process is also discussed. Based on these studies, by considering the configuration and constraints of axial magnetic bearings for a flywheel energy storage system, the authors put forward a rational sequence for designing this product better than the conventional trial-and-error method, which establishes the foundation of the performance sy stem of magnetic bearings.
