The RB is based upon simple, effi¬cient, conventional electrical and mechanical components. Its simplicity leads to very high reliability and low service costs which, added to the energy saved by the low UPS losses and no requirement for air-conditioning, produces a very low Total Cost of Ownership.

The system consists of a standard synchronous generator with no special windings and a simple steel flywheel. The low speed shaft extends bearing life and reduces maintenance. The ROTABLOC machine is very robust as critical functions do not use fragile components such as power electronics, power capacitors, electro-chemical batteries, active magnetic bearings, electro-mechanical or mechanical friction clutches.
