Adoption of gear less wind turbines is nothing but the elimination of gearbox as the weakest link in the design of modern wind turbines. Generally gearboxes lasts for an average 5 years and failing probably due to misalignment operation during the wind turbines life span of approximately 20 years, or due to severe strain and shape changes under sudden wind gusts.
In addition, it eliminates the need for oil cooling avoiding one cause of fires and environmental pollution in the case of the lubricating oil spillage. Like small wind turbines, these have inverters instead of synchronous generators, that is to say, a separate controller that converts the AC electrical power generated into a form that the grid can be fed with. This gearless concept has not yet been universally adopted like the flexible hub concept.
The gearless drive system does not require any oil to separate. The tips of the turbine blades are tilted to reduce noise emissions. The annular generator is of primary importance in the gearless system design of wind turbine. It offers the advantages of totally avoiding the gearbox components. Combine with the rotor hub, it provides an almost friction less flow of energy, while the gentle running of fewer moving components guarantees minimal material wear.
Developing countries such as China, India is mainly responsible for the market growth. Countries such as China, the United States, Germany, Spain, India themselves occupies more than 70 per cent of the market share. While the major share of the opportunities for this market exist in China, Germany and the United States, as these countries are rapidly increasing their new capacity additions to the existing ones.
The only issue with the wind turbine market is that the initial capital investments required is slightly on a higher side when compared to the other non-renewable energy markets in terms of tower installations and turbine and other equipment. Major revolutions happened in the recent years towards the turbine design and installation techniques, which resulted in reducing the initial capital investment required to a fairly reasonable extent.
