What are Flywheel Energy Storage Systems?
Flywheel Energy Storage Systems are interesting solutions for energy storage, featuring advantageous characteristics when compared to other technologies. Research focuses on cost aspects, system reliability, and energy density improvement for these systems. In this context, a novel shaftless outer-rotor layout is proposed.
How can flywheel geometry design improve energy storage performance?
The geometry design of a flywheel can significantly improve its energy storage performance, as studied in this paper focusing on the five most common geometries. The energy storage performance of each geometry is ranked using a proposed procedure. The dimensions used in the study are: t = 5.08 cm or 2″ for the thickness, and h = 14.605 cm or 5.75″ for the radius.
How much energy does a flywheel store?
It would probably have to be in a cement enclosure, and in Florida a sump pump to keep it dry. A 1,000kg, 5m, 200RPM flywheel would store 685,567J of energy if it was shaped like a disc. That's 0.19kWh of energy — enough to boil the water for about seven (7) cups of tea or run a typical airconditioner for about 10 minutes.
How does a flywheel system work?
The flywheel system is hermetically sealed and operates in a vac-uum environment to minimize windage loss created by the large-diameter high-speed flywheel rotor.
What is the height of the flywheel housing?
The height of the flywheel housing is 940mm, and the diameter is 350mm. The design details can be found in .The flywheel system utilizes patented homopolar permanent magnet biased active magnetic bearings for rotor radial and axial support.
