Energy storage flywheel emergency power source and methods

摘要: A flywheel energy conversion device provides highly efficient between kinetic and electrical energy. The produces increased output by providing armature coils in an air gap formed about the (both radial axial embodiments are described). In preferred embodiments, field of a magnetic circuit energized with DC drive current that creates homopolar flux within rotating solid rotor having teeth cut from flat disk. total reluctance remain substantially constant as rotates. may travel radially outward exit disk through passing across gap. Airgap preferably utilized which changing density (due to teeth) induces voltage coils. is diffused before returning one several ways such core losses effectively reduced, thereby enabling operate efficiently at high frequencies.
