How fast will the wind turbine blades rotate?
It decided by which model you choosed, if you choosed big size wind turbine like 1MW or 2.5MW, which blade rotates very slowly, around 20-30r/min, since most of big size wind turbine which are low-speed wind turbine; if you are using small wind turbine like 1kw-2Kw wind turbine, which rating rotate speed is very fast, it can be getting to 240R/min in rating, of course higher r/min it brings much more noise!
Depending on wind speed, the blades of the wind turbine will complete one rotation in between four and eight seconds. This is equivalent to 8 to 16 revolutions per minute (RPM). Many observers describe this rate of rotation as graceful. Older, smaller wind turbines rotated much more rapidly and had much higher RPMs. Click here to see a video of an offshore wind farm operating off the coast of Denmark.
