To keep from destroying the propellers or the turbine by exceeding maximum tip speeds or thrust forces. The maximum tip speed is the velocity in feet per second of the tip of the propeller making the arc around the circumference. As it nears this velocity the machine would vibrate and tear itself apart. A factor of safety in designing these machines is employed to ensure they never get close to this speed. So a 100 foot propeller would trace an arc with a maximum circumference of 314.15 feet. at 1 RPM the tip of the propeller moves at 50.3 feet per second. Several factors go into determining this safe speed, weather conditions, wildlife concerns, precipitation, thrust forces on the structure, stress fatigue (wear and tear)... etc., all of these factors combine to determine a safe design maximum speed. So large wind turbines spin slowly.

How does the wind cause a turbine to spin?
turbines spin when there is a cause of wind..!!
Do wind turbines spin faster than windmills in light wind?
it would spin slower
Why do wind turbines spin?
Because the wind moves the blades witch causes the turban to go
How is electricity produced by wind energy?
The wind spins the blades which are connected to turbines which cause the turbines to spin and create electricity that is spread across a power grid.
What are those things that spin around called on the wind turbines?
Rotors or blades.

How do wind turbines amke electricity?
they make electricity by wind blowng on the blades makeing the generator spin
What are those things that spin around called on the wind turbines?
Rotors or blades.
How fast wind turbines spin?
It depends on how hard/fast the wind is blowing- the harder/faster the wind blows the faster the wind turbine spins
What type of wind do wind farms use?
Natural air. The power is generated by large turbines that spin when wind blows past. -_- all wind is the same.
What are the white fans that make electricity called?
The white fans that make electricity are called wind turbines. Wind turbines are devices that convert the kinetic energy of the wind into electrical energy through the use of rotating blades. When the wind blows, it causes the blades to spin, which in turn drives a generator to produce electricity. Wind turbines are commonly used to generate renewable energy from wind power.
How can wind flowing water and tides be used to produce electricity?
They can all be used to spin turbines that will generate electricity.
What is the point in wind turbines?
There is no point in wind turbines
What are some of the different designs of wind turbines?
country side wind turbines and modern turbines
