The Savonius wind turbine section allows the combined wind turbine system to start spinning in lower wind conditions, allowing the Darrieus wind turbine section to start spinning at a much lower wind speed compared to if the Darrieus section was separate from the Savonius section as typically the Darrieus style of wind turbine requires higher wind speed to start spinning. A Magnetically Levitated (MagLev) Axial Flux AC motor as part of the wind turbine can achieve the same output in less than half the number of revolutions per minute due to having less friction and containing stronger Rare Earth Neodymium Magnets compared to traditional magnetic arrays. This greatly reduces vibration and resonance from the wind turbine to very low levels.X/. N ----------....... /.....0....... ....... 0. Nz& p 0.....
