... magnet machines very attractive for wind power generators, because in high power wind mills (> 1 MW), a wind turbine rotor is typically rotating about 10 to 20 rpm. One important aspect of ... the power can be generated already at small wind speeds and the power production can be optimized according to the wind and the generator speed. This seems to be a trend also...
