Operation parameters of drivesOperation parameters of drives

Drives with frictional (belt) variators

Works effectively in a range of angular velocities (ωmax/ωmin= 3–6).Efficiency is lower than in a mechanical gear.

Drives with Moment

Works most effectively in only a few points.

Drives with MARS

Works effectively in a wide range of angular velocity (ωmax / ωmin greater than 1000). Works effectively in creeping mode. Efficiency is comparable with the efficiency of a manual transmission.
