Abstract
Magnets and methods of their manufacture are disclosed for use in flywheel assemblies, such that the magnets comprise oriented fibers, such as, for example, axially-oriented fibers in a flexible rotor magnet composition to predictably allow the magnet to expand dimensionally upon rotation only in a predetermined and predictable fashion while maintaining critical contact with a rotor surface.
