Energy storage system for magnetic floating flywheel

Abstract

The utility model discloses a magnetic levitation flywheel energy accumulation system, which has the advantages of small deadweight, large electricity storage, low manufacturing cost, mobile usage, free adjustment of the real-time discharge quantity value to the outside, and quick charge or large real-time discharge; wherein, the axial component of ''the high-vacuum enclosed housing'' is made of materials of low specific gravity. No permanent magnetic material components are positioned on the ''Flywheel'' and the ''Wheel Disk'' is divided into three rings. Four ''Permanent Magnetic Rotating Motor Devices'' are arranged. The ''Magnet bearing'' is ''all magnetic levitation bearing'' or ''semimagnetic levitation bearing''. The utility model is also provided with a device to guarantee the reliability of the mobile usage of the ''Magnet Bearing''.

Description

Maglev Flywheel Energy Storage System (1) Technical field The invention relates to a magnetic levitation flywheel energy storage system. (2) Background technology The magnetic levitation flywheel energy storage system is an energy storage system that includes a high-vacuum sealed shell, a magnetic bearing, a flywheel and a permanent magnet rotating motor device that stores mechanical energy instead of storing electrical energy, such as in US Patent No. US-5124605 or Chinese Patent No. 01126564.7 The energy storage system described. This energy storage system enables the flywheel to exchange electromechanical energy with the outside world with the help of a permanent magnet rotating motor device, and reduces the frictional energy consumption of the flywheel and permanent magnet rotating motor device during operation with the help of a high-vacuum sealed shell and magnetic bearings, thereby allowing the external input Electric energy is well stored in the form of flywheel m...
