1, Goldwind's biggest company is all-permanent magnet motor.
2. The second most promising energy source is doubly-fed machine (rare earth should not be needed).
3. Most of Sanming Yang Technology is directly driven. From the trend, new products seem to be directly driven.
4. Fourth, Shanghai Electric can't see clearly, and it is directly driven and doubly fed.
