The HybridDrive is Winergy's response to the challenge of further reducing the costs of energy generation. With the direct connection of a three-stage planetary gearbox and a permanent-magnet synchronous generator, a medium-speed drive has been designed ensuring the highest efficiency. The compact design makes the drive system shorter by more than 50%, and the efficiency is outstanding among all other technologies
Our gearbox concept High Densityx unites power density, reliability and efficiency on a new level. The concept set new market standards by increasing torque density by more than 25 percent up to 200 Nm/kg while relying on our proven gearbox design.
The increase in power density results from a significant weight reduction and multiple planets in three planetary stages for balanced ratio distribution. High Densityx covers the full portfolio from low wind turbines to large offshore machines.
Benefit from the increased power density and optimized space requirements with the High Densityx.
By introducing the journal bearing technology for its gearboxes Winergy sets another milestone for the wind turbine drive technology. Bearings belong to the critical wear parts of wind gearboxes as they are exposed to high loads in operation and therefore have a significant impact on the overall gearbox reliability. As journal bearings have proven their advantages in several other heavy industries, Winergy developed the technology as an Alternative to common roller bearings.
The journal bearing technology is available for High speed gearboxes the HybridDrive.
Digital Gearbox by Winergy increases the efficiency of wind turbine gearboxes. Our gearboxes can be run with optimum torque and rotation rate by digitalizing and analyzing their operating data including real measured torque. As a result, either the power output or the gearbox service life can be increased. The turbine operator is aware in which phase of the product lifecycle his gearboxes are in and is able to optimize the lifetime according to his needs.
For wind turbines with gearboxes, our specialized generator systems up to 20 MW offer the perfect combination of performance and quality for onshore and offshore applications. Benefit from a generator customized to your individual system type and get to know the wide variety of products on offer.
Our squirrel-cage induction generators are durable, reliable, and easy to maintain. Due to a simple mechanical and electrical design without brushes and slip rings, they are extremely compact and lightweight despite their high performance. The construction and the technical design of the generator therefore have exactly the characteristics that are required in wind power industry.
The generator is completely decoupled from the grid via the frequency converter and can be controlled over a wide speed range. The usual grid fluctuations cannot influence the operation of the generator and the drive train of the wind turbine. The turbine can be optimally adapted to the current wind conditions, resulting in a positive annual value.
The double-fed asynchronous generators have proven themselves thousands of times over worldwide. A rotor fed by the converter is used for speed control. Together, the generator and converter meet all current grid codes. Due to the small size of the rotor converter and the converter losses from the rotor circuit, the system features a high efficiency and low investment costs.
Only about 30% of the generator's rated power is fed into the grid via the converter. In addition to the high efficiency of the generator, this allows an added increase in the efficiency of the system. Come and see our lifetime-optimized and monitored brush slip ring designs.
Synchronous generators using permanent magnet technology are common in the wind industry. The full converter concept offers advantages, such as optimized yield because of the wide speed control range. This is complemented by the benefits of the permanent magnet technology. These include low maintenance and reliability, as no electrical excitation equipment is required. They bear a high efficiency and ultimately ensure a high total energy yield.
We designed these generators with high ruggedness in mind. The magnets are completely protected against corrosion and are short-circuit proof. Further, they set themselves apart as a result of their modularity: They are available in water-cooled and air-cooled versions, for low voltage and medium voltage designs.
The result: They can be optimally adapted to every turbine type.
The gearless Direct Drive wind generator is a multi-pole synchronous machine, usually equipped with permanent magnet technology. Winergy offers you custom-made stators in segmented design for your Direct Drive wind generator.
Based on its modular platform concept, the generator's stator is not manufactured as a whole but is composed of preassembled sub-segments. This offers especially advantages for the transport and erection and allows a customized adaptation to the respective performance requirements. The stator segments are integrated optimally into the drive train of the wind turbine using finite element calculations.
The stator segments are characterized by extreme mechanical accuracy, stability and highest efficiency and reliability of the electrical design. This makes the stator segments ideal for harsh offshore conditions in particular.
The many successfully installed Direct Drive offshore turbines worldwide featuring Winergy stator segments speak for our components' quality and reliability.
More than 40 years of service experience can be felt at every point in our service program. We are just there - with words and deeds, competent and fast. This is ensured by a complete original documentation to provide a history-based service.
Winergy service performs gearbox and generator refurbishment according to the specific failure mode, condition, design status, and original scope of delivery.
Fast and flexible on-site service solutions help Winergy customers to increase turbine availability and reduce their LCoE. With the right approach, a lot can be achieved up-tower.
With us as your service partner, you benefit from high-quality and immediately available spare parts straight from the manufacturer. We stock spare parts for all standard gearboxes and generators for service purposes.
Moreover, Winergy optimizes tooth geometry on the micron level. Spare parts that are not manufactured according to the original specifications can sustain significantly higher wear. Using original spare parts only means an increased lifespan for your wind turbines.
Should it ever happen that a gearbox or generator needs replacement whether as a preventive measure or in the event of damage it is essential to return the wind turbine to operation as soon as possible.
For this purpose, we have an immediately available stock of Winergy replacement components for all common wind turbine models in our exchange pool. We provide this service for series production as well as custom-built Winergy components. We apply the same strict quality requirements to these custom-built Winergy components as to our series production.
As your original service partner we dont keep our expertise to ourselves, we pass it on in order to enable our customers to install Winergy Original Spare Parts on their own, professionally.
