Flywheel magnetic lift and bearing system

A mechanical-energy storage unit comprising:

• a flywheel including a rotatable mass component and one or more axles coupled with the rotatable mass component, the rotatable mass component including:
• a top clamping plate;
• multiple plates;
• a bottom clamping plate, the multiple plates being located between the top clamping plate and the bottom clamping plate;
• and
• a plurality of fasteners coupling the top clamping plate with the bottom clamping plate and applying a compressive force on the multiple plates;
• a magnetic lift component having one or more magnets positioned around a center perforation, the one or more axles passing through the center perforation in the magnetic lift component, the one or more magnets pulling the flywheel toward the magnetic lift component, the top clamping plate being positioned adjacent to the one or more magnets of the magnetic lift component;
• a support structure coupled with the magnetic lift component, the support structure holding the magnetic lift component at a stationary location relative to the support structure, wherein:
• the support structure includes a lid, the rotatable mass component being located inside the support structure;
• the one or more magnets are coupled to a bottom side of the lid;
• and
• the one or more magnets are located inside the support structure;
• and
• one or more bearings coupled with the support structure and the one or more axles to maintain the one or more axles at an axis of rotation, the top clamping plate being attracted to the one or more magnets to reduce a downward force of the flywheel on the one or more bearings.

A flywheel assembly comprising:

• a magnetic lift component having one or more magnets positioned around a center perforation, one or more axles of a flywheel passing through the center perforation in the magnetic lift component, the one or more magnets pulling the flywheel toward the magnetic lift component, the magnetic lift component being held by a support structure, wherein the magnetic lift component includes:
• a backer ring coupled to the support structure;
• the one or more magnets disposed on the backer ring;
• and
• a magnet holder coupled with the backer ring and providing support to the one or more magnets.

A system comprising:

• a flywheel including a rotatable mass component and one or more axles coupled with the rotatable mass component, wherein the rotatable mass component includes:
• a top plate with a flat top surface, the top plate rotating about an axis of rotation, the flat top surface positioned adjacent to one or more magnets of a magnetic lift component, the top plate being attracted to the one or more magnets to reduce a downward force of the flywheel on one or more bearings;
• the magnetic lift component having the one or more magnets positioned around a center perforation, the one or more axles passing through the center perforation in the magnetic lift component, the one or more magnets pulling the flywheel toward the magnetic lift component;
• a support structure coupled with the magnetic lift component, the support structure holding the magnetic lift component at a stationary location relative to the support structure;
• the one or more bearings coupled with the support structure and the one or more axles to maintain the one or more axles at the axis of rotation;
• and
• one or more seals that form an airtight seal between an inside and an outside of a flywheel enclosure, the support structure including the flywheel enclosure, the flywheel being located inside the flywheel enclosure.
