Thousands of times in operation worldwide 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.

Product Number: Double_fed_induction_generator One generator for all cases 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.
Compact and rugged. 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.
