Flywheel 101

What makes CLEANSOURCE® PLUS Systems so special?

The answer is Active Power's patented integrated flywheel UPS technology. Flywheel systems store kinetic energy - energy produced by motion - by constantly spinning a compact rotor in a low-friction environment.

When short-term backup power is required because utility power fluctuates or is lost, the inertia allows the rotor to continue spinning and the resulting kinetic energy is converted to electricity.


  • 4.4" high; 25.5" in diameter; 600 lbs
  • Flywheel constantly spins (~ 10,000 rpm) in a vacuum
  • Each flywheel provides 300kW for ~20 seconds or 150kW for nearly 1 minute
