Current, our country with independent intellectual property rights of the gap wind turbine, the core technology of domestic wind turbine manufacturing is not master. In this regard, the national development and Reform Commission and the Ministry of finance is studying the support scheme of wind turbine machine parts and localization, or will be making machine and spare parts for wind power motor with independent intellectual property rights of the grant funds to support.

At present, the level of development of wind power equipment in China, although it has production capacity of 600kW and 750kW wind turbine, but China's wind power equipment manufacturing enterprises is still in the low-end equipment design and manufacturing level of. Due to the lack of core technology, electrical equipment in our country at present can batch production are developed countries 10 years ago products.

With the continuous innovation of the industrial automation level, linear motor is applied more and more widely. Tamagawa, Panasonic servo motor, the company has products in China, Zhejiang University also has a linear motor products. The world's major companies are vigorously research and development of new products and new applications. Linear motor is asynchronous, synchronous, step by step, DC, brushless DC and other types of.

 

The domestic wind power equipment market is very broad, provide a broad market space for the development of large-scale wind power development of wind power equipment manufacturing industry. At present, the supplier of wind turbine equipment to the decisive role in the selection of automation products, and the wind field investment and management personnel only requires the stable operation of wind power generation equipment, automation has little influence on brand. It is believed that with the small fault wind power equipment market competition intensifies, automation products wind investment and management personnel of the wind power equipment, the influence will be more and more.

With more and more wind turbine manufacturers because of cost considerations, the development focus in VSCF wind power generator, because of its use of direct drive mode, you can not install the gear box, so the variable speed constant frequency wind turbine will gradually become the mainstream market.

So in the coming years, we forecast the average growth rate will be lower than the gear box of wind power generation equipment rate. But not the variable-speed doubly-fed wind turbines disappear immediately, for quite a long time, both will coexist.

Servo system is mainly applied to the variable pitch wind turbine, and all the current R & D wind turbine supplier and production of the products are pitch system based on the unit, early fixed pitch stall wind turbine rarely production.

Therefore, we can think of, the speed of development and the servo product wind power itself can be matched in the wind power growth rate.
