Variapower technology

VariaPower technology is a breakthrough innovation in the field of mechanical variators (CVT). The patented technology at the heart of the Variapower CVT self-adjust to the load without requiring energy, which gives our transmission several advantages:
  • Efficiency is over 98%, which is comparable with gears on all variation range,
  • Low variation energy :
  • Variation of the ratio only requires a few watts,
  • There is no energy consumed outside variation phases,
  • High torque capacity
  • Very high transmission precision with no wear.
We are able to perfectly adjust our technology to your sepcifications, from calculus to design, prototyping and series. Learn more and see our realisations (lien vers services)
