Wind turbine generators: DFIG or PMSG?

Why do wind turbines use Rare Earth magnets? The short answer is that Rare Earth magnets have greater magnetic field strengths (flux densities), which opens up direct drive generator configurations with much lower gearing, and without

6 FAQs about [Rare Earth Nair Wind Turbine Generator]

Where are rare earth elements located in a wind turbine?

Rare earth elements, or REEs, are important parts of a wind turbine’s permanent magnets, located in the center of the blades in the electrical box (called the nacelle). The permanent magnets are mostly used to increase power generation and reduce maintenance in larger offshore wind turbines.

How much rare earth does a wind turbine have?

Assuming 35 million EVs and 3 kg of permanent magnets per EV, plus 100 GW wind turbines with permanent magnets (50% market share) at 0.5 kt magnets/GW, with 30% rare earth content in the magnets (IRENA, 2021). The sudden REE boom reflects these elements’ unique optical and magnetic properties (Adler and Müller, 2014).

What is the future market share of rare earth-based wind turbines?

The future market share of wind turbines that use rare earths will most likely depend on the evolution of the price of rare earths and the techno-economic advantages of PMSG (Permanent Magnet Synchronous Generators) in comparison to alternative technologies that do not use rare earth elements. Previous article in issue Next article in issue Keywords: Rare earths, Substitution, Wind turbines

How many rare earth magnets do wind turbines use?

The wind turbine sector uses very large quantities of a rare earth magnets made from an alloy of neodymium, iron and boron (NdFeB) - and it’s predicted that in 2040 there will be a 240,000 tonne shortfall of rare earth magnets, which will slow down our progress dramatically unless an alternative source is established.

How much rare earth is needed for HTS wind turbines?

The demand for rare earths in HTS wind turbines is estimated to be quite low, at approximately 2 kg REEs/MW. The main rare earth element requested is yttrium, in the range of 0.1–0.8 kg/MW (Wuppertal, 2014), but it can be substituted by lanthanum or cerium (Buchert, 2011).

Do wind turbines use a permanent magnet generator?

Some high-speed wind turbines do not use a permanent magnet generator; medium-speed wind turbines use only one-tenth of the permanent magnets needed in direct-drive turbines.
