Do they require neodynium permanent magnets? AFAIK, there are generators (including big generators at hydroelectric power plants) which use electromagnets instead. The same applies to electric motors; there are some which use permanent magnets, and some (induction motors) which don't.
- philipkglass 5y agoThe majority of wind turbines use electromagnets. You can see it in this industry report graphic: https://nawindpower.com/gwec-tier-one-turbine-suppliers-gained-market-share-in-2018 https://nawindpower.com/gwec-tier-one-turbine-suppliers-gain... "Conventional drive" and "Direct drive - EESG DD" add up to 75.5% market share. These designs don't use permanent magnets.
