Braking Ideas For Wind Turbines

Brakes for wind turbines call for higher cycle rates, higher loads, greater reliability and often in more compact packages than those on conventional factory equipment.

Slowing and halting an 80-m wind-turbine rotor involves converting its kinetic energy into heat. The same mechanical transfer occurs, for example, when stopping a large truck. A 40-ton mining truck, for instance, must be able to stop on a steep gradient.
