Abstract
Techniques for flywheel energy storage devices including magnetic bearings and/or magnetic drives are generally disclosed. Some example magnetic bearings may include a flywheel magnet and a support magnet arranged to magnetically suspend a rotating flywheel. Some example magnetic drives may include at least one drive magnet arranged to magnetically engage a diamagnetic material associated with the flywheel to exert torque on the flywheel.
