Inomax Regenerative drive for flywheel energy storage

Inomax Regenerative drive for flywheel energy storage

2024-07-28

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the flywheel.

Most FES systems use electricity to accelerate and decelerate the flywheel, but devices that directly use mechanical energy are being developed.

 

Advanced FES systems have rotors made of high strength carbon-fiber composites, suspended by magnetic bearings, and spinning at speeds from 20,000 to over 50,000 rpm in a vacuum enclosure.Such flywheels can come up to speed in a matter of minutes – reaching their energy capacity much more quickly than some other forms of storage.

Inomax four qudrant regenerative drive own the same technology than ABB and Siemens ,and with higher efficiency and user friendly as well as more competitive price.
 
For example ,our regenerative drive can control the wheels rotate at a high speed of 20,000-50,000 rpm.
Can make the THDI less than 3%, and 98% energy return back to on-grid power.
During the past 3 years, our regenerative drive are widely used in several flywheel energy storage manufacturers and got good reputation .
