Nested-rotor open-core flywheel

摘要

Methods and apparatuses are disclosed for incorporating a plurality of independently rotating rotors made from high-strength materials with a high-temperature superconductive (HTS) bearing technology into an open-core flywheel architecture to achieve a desired high energy density in the flywheel energy storage devices and to obtain superior results and performance.

主权项

1. A flywheel assembly for storing and releasing energy comprising:
a substantially cylindrical rotor assembly within a vacuum chamber, said assembly comprising a plurality of rotors, each rotor having an inner and outer surface and each rotor having a different radius; at least one stator assembly, each stator assembly in close proximity with a rotor assembly; at least one rotor magnet affixed to the inner surface of each rotor; at least one stator magnet affixed to each stator; and a high temperature superconducting bearing in communication with the rotor and stator assemblies; wherein the rotor magnet and stator magnet are positioned relative to one another to facilitate levitation of the rotor during operation.
