These aging turbines have their rotors swapped out, their blades replaced, and key components like the generator upgraded in order to enhance the machines’ ability to produce electricity from wind.

But another option, popular in offshore wind, is a permanent magnet generator, which contains an enormous ring of brick-shaped rare earth magnets that spin with the rotor to produce electricity.

In wind turbines, the rotor is connected to a shaft, which in turn enters an electrical generator made out of an assembly of magnets and a coil of wire. When the rotor spins the shaft, the shaft ...

Overall, the turbines that provide wind-generated electricity are a great deal, environmentally speaking. They have a “payback” time – that is, the length of time taken for one turbine to ...

German premium wind OEM Enercon has announced a new 6MW onshore wind turbine equipped with a new permanent magnet generator, which it said offers ‘significant improvements’ in annual energy production ...

Through its strong partnership network, Cyclic has already sourced 37 MW capacity of wind turbine generators containing permanent magnets, and 116,000 pounds of MRI machines.

The U.S. Wind Turbine Database contains more than 74,695 wind turbines built since 1980, spread between 1,699 wind power projects in 45 states.

Recycled wind turbines may one day become tiny homes and floating playgrounds Futuristic concepts give new life to retired nacelle casings and turbine blades. Andrew Paul Oct 25, 2024 11:46 AM EDT ...

But another option, popular in offshore wind, is a permanent magnet generator, which contains an enormous ring of brick-shaped rare earth magnets that spin with the rotor to produce electricity.

Offshore wind turbines need rare earth metals. Will there be enough to go around? China dominates production of the crucial metals, and wind companies are scouring the globe for more sources.
