摘要： A crash management system for implementation in a flywheel energy storage system (FESS) is provided. Implementation of such a system entails designing an FESS rim that is highly failure resistant, and designing the FESS such that if one, some, or even all of its components fail, they are physically prevented from accumulating and releasing enough energy to cause rim burst, thus leaving the rim intact and capable of safely remaining spinning even after one or more FESS component failures have occurred.

摘要： Featured is a method for passively-repulsively lifting a rotor assembly (11) of a flywheel energy storage system (10), comprising the steps of mechanically coupling a first permanent magnet (204a) to the rotor assembly (11) and fixedly positioning a second permanent magnet (204b) proximal to the first permanent magnet (204a) so that a repulsive force is generated therebetween causing the first permanent magnet (204a) to move with respect to the second permanent magnet (204b), thereby causing the rotor assembly (11) to be lifted to an operating level. The method further includes applying a radial force sufficient in magnitude and direction to oppose a radial force being generated by the permanent magnet repulsive force. Also featured is a passive-repulsive rotor assembly lift system (100) for a flywheel energy storage system (10) and a flywheel energy storage system (10) including such a repulsive rotor lift system (100).

摘要： In one aspect of the present invention discloses a dual-stiffness damping system for an evacuated energy storage system, the damping system comprising one or more flexible dampers and a plurality of more rigid bumpers, and a method of damping an evacuated energy storage system using dual-stiffness damping. Indeed, under normal operating conditions, a flexible damper, having a stiffness of about 500 lb/in to about 4000 lb/in, minimizes the rigid body critical speed of the rotor assembly of the energy storage system, allowing relative displacement between the stator assembly and rotor assembly but preventing the assemblies from physically contacting each other. Under more extreme external loading conditions, e.g., during an earthquake, the plurality of more rigid bumpers, having a stiffness of about 50,000 to 250,000 lb/in, engages the outer race of the bearing assembly to arrest further relative displacement substantially. In another aspect of the present invention, the dual stiffness damping system is combined with a bearing assembly and a mounting unit to produce a self-contained damping system that can be quickly and easily installed and replaced.

摘要： Several embodiments of a stiff, metallic hub for an energy storage devices are disclosed in the present invention. The stiff hub produces a critical velocity that is significantly greater than the design operating speed of the flywheel assembly so that resonant frequency is never reached during normal operation of the energy storage device's flywheel assembly. The stiff hub comprises a central core section that maintains a tight interference fit with the rotating shaft; an outer rim section that maintains a tight interference with the high-strength, low-density composite fiber rim, in which energy primarily is stored; and a web section that is situated therebetween, extending radially from the rotary shaft. At high operating speeds, the outer rim of the hub expands radially commensurate with expansion of the composite fiber rim so that enough of the outer rim remains in tight interference fit with the composite fiber rim to substantially minimize vibrations.
