Due to the large magnetic resistance of the permanent magnet generator of the vertical axis, it is difficult to cut into the starter fan at 3 M / S wind speed. Running. In order to ensure the safe operation of the mechanical structure of the fan, considering the weight and volume of the wind turbine itself and the installation position and height restrictions, it is impossible to design the blade too wide and too long.
