A permanent-magnet levitation based wind-energy generating unit, passed the technical appraisal organized by the Guangzhou Department of Science and Technology on Monday.

It has been jointly developed and produced by the Guangzhou Institute of Energy Conversion under the Chinese Academy of Sciences and the Guangzhou Zhongke Hengyuan energy Technology Co Ltd. The institute is the only research institution in the areas of comprehensive research and development of new and renewable energy resources in China.

The generator operates without any control systems. Made independently by China, the successful development of the generator will enable China, or even the world, to make a key breakthrough in the technology of wind-energy generation.

Its comparability testing shows that installed with the permanent magnet levitation bearing, the generator will increase its dynamo output by more than 20 per cent, that is to say, at the same wind speed, the generator will increase generating capacity by 20 per cent.
