How are encoders used in wind turbines?
It turns out that high vibration and temperature extremes kill even “heavy duty” optical encoders. So to handle such loads, encoder manufacturers have designed units just for wind turbines. There are three or four basic applications for encoders on the wind turbine, depending on turbine design: Blade pitch, which controls the amount of wind each…
