The Japan Steel Works will develop a large-scale wind generator that is 30% more powerful than the existing wind generator. Although the act to purchase renewable energy started in July, Japan does not have so many areas suitable for wind generation. Accordingly, demand for large-scale powerful wind generators is expected to grow, the company predicted. The new mode named J100 will have an output of 2,700 kW and begin operations in 2013.
The conventional wind generator turns a turbine at high speed by increasing the revolution of blades using an overdrive, but gears and bearings of an overdrive are liable to let it break down. The company plans to adopt a structure that does not need an overdrive for the new model to make it free from breakdown. The company recorded sales of nearly 2 billion yen from wind generators in fiscal ended May 2012 and wishes to increase them to 19 billion yen in fiscal ending March 2015.
