How torque converters work
Torque converters are hydrodynamic transmissions 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 optional adjustable guide vanes. The pump wheel converts the motor's mechanical energy into kinetic fluid energy. 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, which results in 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 reduces 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 retrofitting 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. When designed as a true starting motor, the driver will be smaller, space-saving, and more economical.
Gas turbine starter
Other functions include:
- Turning of the gas turbine utilizing 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 substantial cost 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.
