    A vertical-axis wind turbine’s (VAWTs) main rotor shaft is set vertically and the main components are located at the base of the turbine. Among the advantages of this arrangement are that the generator can be placed close to bottom of the turbine, which makes these components easier to service.Wind Turbines: Horizontal or Vertical Axis Machines,Vertical axis wind turbines (VAWTs as some people call them) are a bit like water wheels in that sense. (Some vertical axis turbine types could actually work with a horizontal axis as well, but they would hardly be able to beat the efficiency of a propeller-type turbine).,
