Aug 07, 2017· 1.3.3 A good vertical axis wind mill has to remain stable when it is spinning it. If not, the turbine will "shake its head" when the rotor is turning. That will reduce the turbine's life and cause other problems such as noise and mechanical wear. So the best solution is to use a coaxial structure for the wind mill and generator.

A variable speed wind turbine is one which is specifically designed to operate over a wide range of rotor speeds. It is in direct contrast to fixed speed wind turbine where the rotor speed is approximately constant. The reason to vary the rotor speed is to capture the maximum aerodynamic power in the wind, as the wind speed varies.
