THE SUPERCONDUCTION FLYWHEEL ENERGY SAVING APPARTUS FOR INCREASING THE ENERGY SAVING EFFICIENCY

摘要

PURPOSE: A super conductive flywheel energy saving device with increased energy saving efficiency is provided to prevent lowering of energy saving efficiency due to eddy currents. CONSTITUTION: A motor generator includes a cylindrical rotor(100), a stator, a back-iron, and a superconductive magnetic bearing. The cylindrical rotor has a protrusion pole(100a). Stator poles(220a~220h) are included in the stator. The back-iron is mounted on the stator. The super conductive magnetic bearing surrounds a rotation axis part. The super conductive bearing fixes the rotation axis part to a fixed location without a contact. The motor generator prevents eddy currents.
