Variable Speed Drives

Variable Speed Drives (VSD),
Adjustable Speed Drives (ASD)

Voith variable-speed drives operate on the principle of hydrodynamic power transmission. They control the speed of the driven machine in drives with electric motor or combustion engine. The driven machine always runs at the optimum speed for the process. This technology is energy efficient and environmentally-friendly thanks to lower CO2 emissions.

Our product portfolio includes:

  • Variable speed fluid couplings
  • Geared variable-speed couplings
  • Variable-speed planetary gear Vorecon and WinDrive
  • Hydrodynamic torque converter

The Voith variable-speed drives transmit power through moving fluid. They operate very reliably without power electronics that are prone to interference. The transmittable power ranges from 45 kW up to over 65 MW.
