How torque converters work
Torque converters are hydrodynamic transmissions, that were invented based on the ”Foettinger Principle“. They transmit the torque of the driving motor wear-free and steplessly, within a closed circuit.
This closed circuit consists of a pump, turbine and guide wheel with adjustable guide vanes, as an option. The mechanical energy of the motor is converted into kinetic fluid energy through the pump wheel. In the turbine wheel, this kinetic energy is converted back into mechanical energy and transmitted to the output shaft. The adjustable guide vanes regulate the mass flow thereby providing variable output speed.
- Fixed guide vanes with different characteristics
- Adjustable guide vanes for accurate speed control
- Filling and draining valves, gears and turning device

Your complete system solution
This all-inclusive solution assists in reducing site assembly, alignment, and commissioning time as the components of the packaged starting system are selected to complement each other, achieving an economical and space conscious design.
The torque converter, motor, and all required accessory equipment are factory mounted onto a common base. For more demanding requirements, such as the retrofitting of a unit to an older gas turbine, a self-contained packaged starter design can include an integral oil tank. Additionally, an optional onboard PLC system can be fitted to control the various phases of the starting sequence.
Furthermore, the driver (motor) can be used above its continuous rating during the short start-up of the gas turbine. The driver when designed as a true starting motor will be smaller, space saving, and a more economical.
Gas turbine starter
Other functions include:
- Turning the gas turbine by means of the integral turning gear for slow-roll functions
- Indexing the gas turbine for inspections
- Fast spin-cooling of the gas turbine for ease of maintenance
- Extended gas turbine water-wash cycles
Test field drives
- Volumetric pumps
- Chain conveyors

The revolutionary pump drive and subsea coupling system
Voith has partnered with Fuglesangs Subsea to develop an advanced pump drive and coupling system, leading to outstanding reliability and huge costs savings. By integrating a Voith torque converter into the pump on the sea floor, electrical variable frequency drives on the topside are no longer required for speed control.
