Product details
Compact, economical, robust: The key benefits of the E-Pack DS are clear to see. But what do they mean in practice for your operations? Click the headings below to learn more.
Compact
Streamlined design for extra efficiency
At up to 30% shorter and as much as 10% lighter, the E-Pack DS enables greater flexibility throughout your operations. Extra efficiency allows you to make greater use of less space, while added simplicity promotes swifter execution of workflows and orders. All this boosts the bottom line for OEMs.
Added value
- One package, fewer interfaces, less overall engineering
- Torsionally and laterally optimized drive system
- Easier on-site deployment at OEM and end user
- Uses fewer resources and has better CO2 footprint
up to 30% smaller footprint
30% reduced footprint with E-Pack DS from Voith and ELIN Motoren
Economical
Reduce power losses, save money
Featuring minimum gear components and bearings, the E-Pack DS outperforms the overall efficiency of a parallel shaft gearbox by up to 1%. A truly harmonized electromechanical drive package, it typically delivers a return on investment (ROI) within 2-3 years – and boosts profits for 20-30 years.
Added value
- Lower power losses and oil temperatures
- Lower operational costs
- Longer-lasting oil and components
- Environmentally friendly package
Robust
One package, fewer interfaces
Fewer components mean more reliability and efficiency, while
fewer bearings enable improved dynamics. In a further boost
to standardization, the gearbox does not require a foundation.
The gear unit and electrical machine use standard oil supply
and drain lines for easy on-site alignment.
Added value
- Harmonized operation and maintenance
- Less lubrication oil, longer service life
- Better spare parts management
- Optimized earthing concept

As a unique synchronized package featuring an electrical machine with an integrated gearbox,
the E-Pack DS sets the benchmark for compact and effective electric drivetrains.
The E-Pack DS can be deployed in retrofits and new developments across a range of settings including the chemical and petrochemical industry, oil and gas production, and power generation.
You can further customize your setup via a series of flexible extension options. These encompass the mechanical oil pump turning gears, rotor turning device, and base frame, as well as the lube oil system and jacking oil system.
Applications
The E-Pack DS is your ideal drive system upgrade for numerous industries, from chemicals and petrochemicals to power, oil and gas. Suitable for motor-driven compressors and pumps as well as generators driven by gas or steam turbines, it does more with less space. From generators in mobile containers to offshore applications and beyond, our drive system combines a small footprint, low weight and high efficiency.
Compressors and pumps
Power and speed in a wide range of settings
The E-Pack DS serves all segments that require turbo-geared electrical machines. It delivers up to 30 MW of power, even reaching 40 MW in special applications. The low- and high-speed shafts on this epicyclic gear unit can deliver speeds as high as 1,800 rpm and 17,000 rpm respectively – and up to 3,600 rpm and 35,000 rpm in specific cases.
Steam and gas turbine
Boosting efficiency of your turbine
The E-Pack DS connects your steam turbine or gas turbine with the synchronous generator, typically running at 1,500 or 1,800 rpm, while the high-speed shaft on this epicyclic gear typically receives speeds between 3,000 rpm and 10,000 rpm from the turbine. The available power range starts from 1 MW and reaches output values up to 40 MW. Compared to traditional parallel-shaft gear installations, the E-Pack DS will improve the gearbox efficiency up to 1%.
