Once the yaw ring is installed, the nacelle main frame must be turned over in order to complete the yaw system assembly. Temporary legs are installed, and fixtures are added to the yaw ring. The main frame is lifted, and one side is let down while the frame is rotated. Here you can see the…

In the 1970s oil crisis, many countries began to explore alternative energy options and their viability. In the US, NASA, and the Department of Energy have collaborated to develop a series of megawatt large research wind turbines known as Mod series. The Mod Series The wind turbines developed in the mod series were very expensive…
Power from the yaw motors is transmitted to the yaw ring through a reduction gearbox which provides both speed reduction and torque multiplication. This yaw drive uses a planetary gearbox with the motor mounted vertically at the top. Planetary gearboxes are often used on commercial wind turbines because they offer high reduction ratios from a…
