• Less than 1% rated power standby losses
  • Cycle every 75 seconds continuous duty
  • Custom engineered parallel capability for high power ratings
  • Lifespan of 10,000,000 charge-discharge cycles

Kinetic Traction's unique high-speed carbon flywheel systems feature high cycling composite rotors running on magnetic and hydrodynamic bearings at up to 36,000 RPM to provide 200kW each. Our systems are capable of delivering more than 1000 charge-discharge cycles per day for 20 years with minimal maintenance.

The GTR flywheel utilizes a fully integrated, permanent magnet, brushless, DC motor generator to provide clean energy capture with significantly lower costs than traditional energy substations. The GTR flywheel technology was introduced nearly 20 years ago and tested in major rail and subway systems in New York, London and Lyon. KTSi builds on this technology, pioneered in the 1990's, to develop high-speed flywheel systems that absorb and deliver power more reliably, economically and effectively than any competing technology.
