Magnet for MW Wind Generator has very high comprehensive performance, so it can stand extremely harsh environment and own very long life time. 
About 21% of our  magnets are used in wind generator.We has successfully produced many specifications for wind generators. 
And we not only have obtained the certification for Permanent Magnet Industrialization for MW wind PMG, but also have more than 10 invention patents and application patents on material research and equipment improvement for magnets of PMG .
Most of the wind generator magnets are large block shape, tile shape and wedge shape in Ni+epoxy coating,the grade is always in M,H,SH series.In 2014,the new production line which has the imported Germany and Japan equipment it will help to improve the property consistency of the big wind generator magnet and the production efficiency.

Detailed specifications:
1.Size: Custom-made according to your requirements.
