How It Works:

The Liebert FS stores energy kinetically. When needed, inertia of the spinning mass is immediately converted to power. The Liebert FS is a functional replacement or supplement for a bank of chemical batteries. Like batteries, it charges from the two terminal UPS DC bus and returns up to 190 kW per module whenever the bus voltage drops below a programmable threshold.

The flywheel itself is a high-speed, carbon fiber composite cylinder rotating in a vacuum. The flywheel and rotating group is fully levitated and centered by patented 5-point magnetic levitation system that minimizes drag and eliminates mechanical bearings maintenance and replacement. Its synchronous reluctance motor-generator minimizes idling losses and standby power consumption. Originally designed for hybrid vehicles, the levitation system is very robust and responsive to any jarring.
