When you drive past a wind farm the massive white blades seem to be turning in a slow and lazy circle. This optical illusion makes many people wonder exactly how fast these giant machines are actually moving. The truth involves complex aerodynamics strict safety limits and the surprising reality that faster rotation does not always equal more electricity. The Aerodynamics of Rotor Speed and Tip Velocity To understand how fast a turbine spins you must separate two different measurements which are the rotor speed and the tip speed. The central hub or rotor usually turns at a very slow pace of around ten to twenty revolutions per minute. From a distance this looks incredibly sluggish. However the blades on modern turbines are massive and
