Abstract
An optimized flywheel energy storage system utilizing magnetic bearings, a high speed permanent magnet motor/generator, and a flywheel member. The flywheel system is constructed using a high strength steel wheel for kinetic energy storage, high efficiency magnetic bearings configured with dual thrust acting permanent magnet combination bearings, and a high efficiency permanent magnet motor generator. The steel wheel provides a cost effective, high speed construction for the energy storage rotor.
